Pirates of Silicon Valley Movie Review

It exposed the history and growth of personal computer industry. This movie is between Steve Jobs for Apple and Bill Gates for Microsoft, it illustrates the hardships and milestones of the two prominent companies in order to gain what they have today. The story started with IBM at the early 1980’s. The apple company which is founded by Steve Jobs and his friend ‘Waz’ started doing computers in a garage and reap the idea of graphical user interface from Xerox, a company who developed mouse and standard interface styles that we know today. Xerox let apple look everything they had and naturally, Apple stole everything they could.

On the other hand, Bill Gates formed his company called Microsoft who makes software like operating systems. IBM and Microsoft agreed that the new operating system called DOS will be used in all IBM machines, with this started the Microsoft dynasty. Apple and Microsoft became great rivals on the industry. The movie represents how technology evolves between friendships, Gates and Jobs who are friends became rivals because of their ambitions for their companies. But besides all of this, we should be still grateful for their inventions which we enjoy today.

I-Robot Movie Review

Human seek for convenient, comfortable and easy life. People invent and discover new technologies to make work fast and upgrade our way of living. Machines and robots are some of these inventions, which are a great help in our day to day lives.

The movie was all about the interaction of humans and robots living on the same world. The story started in the year 2035 where is the time of ‘robotophobic’, which means era of robots. In this time, robots are assistants and workers of humans. Robots follow the orders of humans and they work for their human owner. To live together with no harm, there are these 3 laws that robots need to follow and these are the following: first, they cannot harm a human. Two, they must follow whatever they are told by a human being as long as it doesn’t affect law one. And third, they have to defend their selves as long as it doesn’t affect law 1 and 2. Because of an incident, the suicide of Dr. Alfred Lanning, Detective Del Spooner and his friends discovered that there is a killer behind this, and it is VIKI (Virtual Interactive Kinetic Intelligence).

Robots under VIKI started to harm humans and have a plan to dominate the world but through the help of a robot named Sonny, Spooner stopped the mad robots and brought back to their old program. In this movie, humans relied so much on robots that they haven’t expected that these would go against them. It is not bad to explore new technologies and use them for convenience but too much relying would also harm all the human beings as well.

Wall-E Movie Review

The movie was all about a load lifter robot that was made by the Buy-N-Large Corporation. His name is WALL-E, short for Waste Allocation Load Lifter Earth-Class. Its job is to compress all the tons of trash that are caused by human consumption. Wall- e is so dedicated with his job that all his time is spent to it. The non-stop disposal of humans made the earth a place full of garbage and they rely too much on machines that does everything for them even the simplest work.

As a result, humans became fat and can’t able to walk while busy sitting and do virtual things. On the other hand, wall-e as garbage cleaner realized after a long time of doing what he was built for finally discovers what he meant for. Everything changes when he met the love of his life, EVE, a female egg-shaped robot that caught his heart and caused new insights for wall-e.

The movie was fantastic knowing that it extends its real essence to the audience even in the first part, dialogues are minimal. It portrays the effect on continuous dependency of humans on machine. It wants us to realize that technology is a great benefit for all mankind but too much relying on it would make us all worthless.

Assignment #9

Identify an information environment of your choice and write an essay to address the following questions: (3000 words)• What should be your role within this environment?
• How can the principles of information organization and representation help you in performing this role?
• What are the challenges facing you in performing the role? How will you address these challenges?

Technology today is quickly evolving. The things that we don’t know will be known easily through the Internet and it is because of technology. In this assignment, my task is to identify an information environment of my choice and state my role as a student in this environment. In addition, I should be able to explain how the principles of information organization and representation help me in performing my role. Lastly, I will be able to know the challenges that I’m facing in performing the role and how I will address to these challenges, but before anything else, what is an Information Environment?

Information Environment is the aggregate of individuals, organizations, or systems that collect, process, or disseminate information; also included is the information itself. It helps people to access to electronic resources, new environments for learning, teaching and research, guidance on institutional change, and provide advisory and consultancy services.

There is now a critical mass of digital information resources that can be used to support researchers, learners, teachers and administrators in their work and study. The production of information is on the increase and ways to deal with this effectively are required. There is the need to ensure that quality information isn’t lost amongst the masses of digital data created everyday. If we can continue to improve the management, interrogation and serving of ‘quality’ information there is huge potential to enhance knowledge creation across learning and research communities. The aim of the Information Environment is to help provide convenient access to resources for research and learning through the use of resource discovery and resource management tools and the development of better services and practice. The Information Environment aims to allow discovery, access and use of resources for research and learning irrespective of their location.

The Information Environment that I have chosen is The Meta Information Environment of Digital Libraries. The meta-information environment of a library is the aspect of library structure that is likely to be most affected by Digital Library technology. It is important to design meta-information environments for Digital Libraries that simultaneously compensate for the loss of many of the services of librarians and take advantage of the ability to apply digital processing to information objects in the collection of Digital Libraries.

Meta-Information Environment of Digital Libraries

Libraries are organized to facilitate access to controlled collections of information. Traditional libraries (TL's) possess three organizational characteristics that, together, provide a basis for such access. These are the organization of information into physical information objects (IO's) such as books; the physical organization of the collections of IO's according to various attributes, such as subject matter and author; an organized information environment that facilitates direct access to the IO's based on such attributes as author, title, and subject matter, as well as a limited degree of indirect access to the information contained in the IO's.

This last characteristic of a TL typically involves multiple sources of information to support access, such as librarians, catalogs, and the manner in which the collections are organized physically. Since it involves information about information, we term this characteristic the meta-information environment of a library.

As currently conceived, digital libraries (DL's) are libraries in which the controlled collections are in digital form and access to the information in the collections is based almost entirely on digital technology. From a user's point of view, digital technology changes the three organizational characteristics of TL's. First, the organization of information into physical IO's is replaceable with a more flexible organization into logical IO's. Second, the single physical organization of a collection of IO's is replaceable with multiple logical organizations of IO's.

The third and most significant changes, however, occur in the meta-information environment of a library. In terms of advantages, having the IO's in digital form permits the use of digital technology in extracting information from the IO's. The extracted information may satisfy a user's ultimate need for information or it may be employed by “digital librarians'' in characterizing the IO's in the collection. In the latter case, this meta-information may be employed in providing access to the information encoded in the IO's. In terms of disadvantages, important interactions between librarians and users that occur in the meta-information environments of TL's may be lost with the near-automation of information access in DL's.

The term ``metadata'' has been applied in a large variety of contexts. For example, the topics of papers at a recent conference on metadata ranged from metadata in data dictionaries and its use in controlling the operations of database management systems; to metadata used for describing scientific datasets and supporting data sharing among scientists; to metadata used in DL's to support user access to information.

The concept of metadata, when applied in the context of current libraries, digital or traditional, typically refers to information that provides a (usually brief) characterization of the individual IO's in the collections of a library; is stored principally as the contents of library catalogs in TL's; is used principally in aiding users to access IO's of interest.

As an example of its use in the context of TL's, the term ``metadata'' is sometimes used to describe the descriptive cataloging that is specified by the Anglo-American cataloging rules and the MARC interchange format. Such information constitutes a major component of the cataloging information in most TL's. As an example of its use in the context of DL's, the term ``metadata'' has been used to describe the information of the ``Dublin Core'' and the associated ``Warwick Framework'' which is intended to support access to information on the World Wide Web. The Core specifies the concrete syntax for a small set of meta-information elements, and the Framework specifies a container architecture for aggregating additional metadata objects for interchange.

More generally, however, if one surveys the many contexts in which it has been applied, it becomes apparent that the concept associated with the term ``metadata'' is the principal focus of an emerging area of the information sciences whose goal is to discover appropriate methods for the modeling of various classes of IO's. Since a model of an IO is itself typically an IO, and since the concept that is generally associated with the term ``data'' is subsumed by the concept associated with the term ``information object'', it seems preferable to use the term ``meta-information'' and to define it as a model of an information object.

A Scenario for the Use of the Meta-information Environment in a Traditional Library

For the sake of concreteness, let us assume a user whose interest is in finding information on condor re-introduction programs in California. In order to access such information in a TL, the user may engage in a variety of activities. The four most important activities include consulting a librarian; consulting available catalog and reference materials; browsing through the open collections of the library; and processing the information that has been accessed.

Let us assume that the user begins a search by consulting a librarian, and indicates an initial interest in discovering whether programs for re-introducing condors from captive breeding populations have been a success. Several important processes may co-occur during these interactions. First, the librarian may build a ``cognitive model'' of the user that is employed in helping the user. As an example, the librarian may note the user's level of knowledge about the use of a library, and discover that the user does not understand the value of subject heading catalogs in searching for references to information on the decline of the condors.

Second, the librarian may build a cognitive model of the user's information requirements, or ``query'', typically in an iterative process during which the user may change the initial query. The librarian may discover, for example, that the user would like to know the locations of the release sites in order to visit them. Third, and depending on the context of the query, the librarian may also construct a model of the user's information processing requirements. In terms of our example, these might include estimating the time to hike to the release sites.

In conjunction with these emerging models of the user's knowledge base and information needs, the librarian employs a cognitive model of the library's information resources to determine an appropriate set of actions that will lead to the satisfaction of the user's information needs. Three classes of activities are worthy of note. First, the librarian may direct the user to meta-information, such as the subject catalog, that points directly to IO's of interest. Second, the librarian may guide the user to ``general'' meta-information that can be used in a less direct manner in finding IO's of interest. For example, the user may be directed to a gazetteer in order to find the geographical coordinates of the release sites, whose names the librarian may happen to know. These coordinates may then be used in accessing the appropriate maps from the library's map collection. Third, the librarian may suggest that the user browse in the ornithology section of the library to look for books that may be relevant to the topic of condors. In so doing, the user may assess meta-information in the form of titles and tables of contents.

Before leaving the library, the user may employ the relevant maps to estimate the time it would take to hike to the condor release areas.

A Characterization of the Meta-information Environment of a Traditional Library

The preceding example, which is by no means artificial, emphasizes the fact that the meta-information accessed by users of TL's in satisfying their information needs is not restricted to the meta-information in the author, title, and subject catalogs. In particular, the scenario was devised to emphasize that, during search, a user may conceivably employ as meta-information almost all the information sources in a library. Such sources range from the librarian's general knowledge of the world to information encoded in the IO's on the stacks.

An analysis of the preceding and similar usage scenarios suggests that one may further characterize the meta-information environment of a library in terms of a simple model involving sets of services for
coordinating user interactions with the meta-information environment, exemplified in the above scenario in terms of the user's interactions with the librarian; constructing models of the user, the user's query, and the user's workspace requirements, exemplified in our scenario by interactions with the librarian; providing access to models of IO's, exemplified in our scenario by use of the subject catalog and browsing among the stacks; making matches between the model of user queries and models of IO's, exemplified in our scenario in part by actions of the librarian and in part by actions of the user in relation to such library resources as the subject catalog; extracting information from retrieved IO's, exemplified in our scenario by the computation from the maps of the time it would take the user to hike to the release sites. creating models of IO's which, although an important service of the meta-information environment of libraries, is not exemplified in the preceding scenario.
The scenario emphasizes the key role played by librarians in providing services in the meta-information environment of many TL's.

Knowledge Representation Systems in the Meta- information Environments of Libraries

In order to analyze further the manner in which the preceding sets of services provide support for user access to information, it is useful to introduce the concept of knowledge representation systems (KRS's). We argue that an important component of the functionality of the six sets of meta-information services in TL's is provided by a diverse set of KRS's. This conceptualization in terms of KRS's provides a useful theoretical framework for the design and analysis of DL's.
A KRS may be defined as a system for representing and reasoning about the knowledge in some domain of discourse, and is generally comprised of: an underlying knowledge representation language (KRL), whose expressions are intended to represent knowledge about some domain of discourse;
a semantics that gives meaning to the expressions of the KRL in terms of the domain of discourse;
a set of reasoning rules that may be employed in inferring further useful expressions from a given set of expressions; a body of knowledge about the domain of discourse expressed in terms of the KRL.
Concepts similar to the concept of a KRS that have been used by other researchers in relation to meta-information include formal systems with interpretations and semi-formal systems.

In general, we may view the KRS's of a library as providing a diverse set of services that are of particular value in the modeling of both IO's and user queries. They are, for example, of particular significance in supporting the modeling of IO's in terms of their content, since, in principle, the content of library materials may refer to any representable aspect of our knowledge.
In order to gain further insight into the nature and significance of KRS's, we provide examples of their use in supporting key sets of services in the meta-information environments of TL's.

KRS supporting the User Query and IO Modeling Services
Thesauri are an important class of KRS's that are employed in constructing models of the subject matter (or ``content'') of IO's for the catalog systems of TL's. The motivation for the use of thesauri is the difficulties that arise from using a KRS based on natural language (NL) in this context. These difficulties arise from the syntactic and semantic complexity and the high levels of ambiguity that are typically associated with general expressions in NL. The KRL of a thesaurus, on the other hand, is designed to possess a restricted syntax and semantics that permits the representation of restricted domains of discourse in an unambiguous manner. These restrictions result in the construction of many domain-specific thesauri, which in essence represents a ``divide-and-conquer'' approach to building unambiguous representations of a complex world.

For the present purpose, we may use a highly-simplified view of a thesaurus that is abstracted from the ANSI-NISO standard for thesauri.

The KRL of a thesaurus may be viewed as specifying the terms of a simple language and a few relations (or predicates) defined on the terms. These predicates include the three ``broad term/narrow-term'' predicates, the ``related term'' predicate, and the ``synonymous term'' predicate.

In relation to the semantics associated with its KRL, a term defined in a thesaurus is intended to denote a single concept. Typically, terms represent classes of entities, although class instances are permitted. Ambiguity arising from synonymous and homonymous terms is effectively removed. The mapping from terms to concepts is provided informally by the cognitive processing of the reader of the terms.

With respect to reasoning procedures, the use of the basic inference rules of logic (such as ``if A and A implies B are both true, then B is true"), together with axioms involving the various predicates (such as ``if A is a narrow term for B, and B is a narrow term for C, then A is a narrow term for C''), it is possible to carry out simple reasoning that is interpretable in terms of the concepts being represented in the KRL.

In terms of viewing a thesaurus as representing a body of knowledge about some aspect of the world, the terms and predicates of a thesaurus represent a set of concepts and their relations that model some aspect of the world.

Large numbers of thesauri are currently employed in library contexts. The representation of the content of IO's is typically achieved by choosing a relatively small number of terms from some domain-specific thesaurus.

Another important research issue concerns the construction of semantic mappings between the KRL's of different KRS's. It is possible to employ different sets of KRS's for modeling user queries and for modeling IO's. There is therefore a need for translation during the application of matching services. One approach to constructing such mappings involves the use of human experts working in a top-down manner, which is likely to be a time-consuming and controversial process. An approach that is promising in terms of automation involves bottom-up techniques based on empirical analyses of the use of language.

As a student, I do research most of the time. Through digital library, I don’t need to go to the library, refer to the card catalog and find the book to get the information that I need. I will just simply refer to the digital libraries over the Internet. It is my responsibility to use this technology advantage well for better, but still don’t forget to give credits and importance to traditional library and its ways.

Assignment #8

What is outsourcing? What is in-source? Which is better outsource or in-source? Before anything else and before I state my stand on this topic, let us be acquainted with outsource and in-source, and what are their advantages and disadvantages.

Outsourcing is an arrangement in which one company provides services for another company that could also be or usually have been provided in-house. Outsourcing is a trend that is becoming more common in information technology and other industries for services that have usually been regarded as intrinsic to managing a business. In some cases, the entire information management of a company is outsourced, including planning and business analysis as well as the installation, management, and servicing of the network and workstations.
Outsourcing can range from the large contract in which a company like IBM manages IT services for a company like Xerox to the practice of hiring contractors and temporary office workers on an individual basis.

Outsourcing involves the transfer of the management and/or day-to-day execution of an entire business function to an external service provider. The client organization and the supplier enter into a contractual agreement that defines the transferred services. Under the agreement the supplier acquires the means of production in the form of a transfer of people, assets and other resources from the client. The client agrees to procure the services from the supplier for the term of the contract. Business segments typically outsourced include information technology, human resources, facilities, real estate management, and accounting. Many companies also outsource customer support and call center functions like telemarketing, CAD drafting, customer service, market research, manufacturing, designing, web development, print-to-mail, content writing, ghostwriting and engineering. Offshoring is the type of outsourcing in which the buyer organization belongs to another country.

Outsourcing and offshoring are used interchangeably in public discourse despite important technical differences. Outsourcing involves contracting with a supplier, which may or may not involve some degree of offshoring. Offshoring is the transfer of an organizational function to another country, regardless of whether the work is outsourced or stays within the same corporation/company.

Multisourcing refers to large outsourcing agreements. Multisourcing is a framework to enable different parts of the client business to be sourced from different suppliers. This requires a governance model that communicates strategy, clearly defines responsibility and has end-to-end integration.

Strategic outsourcing is the organizing arrangement that emerges when firms rely on intermediate markets to provide specialized capabilities that supplement existing capabilities deployed along a firm’s value chain. Such an arrangement produces value within firms’ supply chains beyond those benefits achieved through cost economies. Intermediate markets that provide specialized capabilities emerge as different industry conditions intensify the partitioning of production. As a result of greater information standardization and simplified coordination, clear administrative demarcations emerge along a value chain.

Due to the complexity of work definition, codifying requirements, pricing, and legal terms and conditions, clients often utilize the advisory services of outsourcing consultants or outsourcing intermediaries to assist in scoping, decision making, and vendor evaluation.

The competitive pressures on firms to bring out new products at an ever rapid pace to meet market needs are increasing. As such, the pressures on the R&D department are increasing. In order to alleviate the pressure, firms have to either increase R&D budgets or find ways to utilize the resources in a more productive way. There are situations when a firm may consider outsourcing some of its R&D work to a contract research organizations or universities.

Reasons why a firm could consider outsourcing are:
-new product design does not work
-project time and cost overruns
-loss of key staff
-competitive response
-problems of quality/yield.


Here are some reasons why companies prefer outsourcing:

Cost savings. The lowering of the overall cost of the service to the business. This will involve reducing the scope, defining quality levels, re-pricing, re-negotiation, cost re-structuring. Access to lower cost economies through offshoring called "labor arbitrage" generated by the wage gap between industrialized and developing nations.

Focus on Core Business. Resources are focused on developing the core business. For example often organizations outsource their IT support to specilaised IT services companies.

Cost restructuring. Operating leverage is a measure that compares fixed costs to variable costs. Outsourcing changes the balance of this ratio by offering a move from fixed to variable cost and also by making variable costs more predictable.

Improve quality. Achieve a step change in quality through contracting out the service with a new service level agreement.

Knowledge. Access to intellectual property and wider experience and knowledge.

Contract. Services will be provided to a legally binding contract with financial penalties and legal redress. This is not the case with internal services.

Operational expertise. Access to operational best practice that would be too difficult or time consuming to develop in-house.

Access to talent. Access to a larger talent pool and a sustainable source of skills, in particular in science and engineering.

Capacity management. An improved method of capacity management of services and technology where the risk in providing the excess capacity is borne by the supplier.

Enhance capacity for innovation. Companies increasingly use external knowledge service providers to supplement limited in-house capacity for product innovation.

Reduce time to market. The acceleration of the development or production of a product through the additional capability brought by the supplier.

Commodification. The trend of standardizing business processes, IT Services and application services enabling businesses to intelligently buy at the right price. Allows a wide range of businesses access to services previously only available to large corporations.

Risk management. An approach to risk management for some types of risks is to partner with an outsourcer who is better able to provide the mitigation.

When done for the right reasons, outsourcing will actually help your company grow and save money. There are other advantages of outsourcing that go beyond money and here are some of them:

Focus On Core Activities. In rapid growth periods, the back-office operations of a company will expand also. This expansion may start to consume resources (human and financial) at the expense of the core activities that have made your company successful. Outsourcing those activities will allow refocusing on those business activities that are important without sacrificing quality or service in the back-office.

Cost And Efficiency Savings. Back-office functions that are complicated in nature, but the size of your company is preventing you from performing it at a consistent and reasonable cost, is another advantage of outsourcing.

Reduced Overhead. Overhead costs of performing a particular back-office function are extremely high. Consider outsourcing those functions which can be moved easily.

Operational Control. Operations whose costs are running out of control must be considered for outsourcing. Departments that may have evolved over time into uncontrolled and poorly managed areas are prime motivators for outsourcing. In addition, an outsourcing company can bring better management skills to your company than what would otherwise be available.

Staffing Flexibility. Outsourcing will allow operations that have seasonal or cyclical demands to bring in additional resources when you need them and release them when you’re done.

Continuity & Risk Management. Periods of high employee turnover will add uncertainty and inconsistency to the operations. Outsourcing will provided a level of continuity to the company while reducing the risk that a substandard level of operation would bring to the company.

Along with its advantages are the disadvantages and criticism of the public about outsourcing. Here are some of them.

Loss Of Managerial Control. Whether you sign a contract to have another company perform the function of an entire department or single task, you are turning the management and control of that function over to another company. True, you will have a contract, but the managerial control will belong to another company. Your outsourcing company will not be driven by the same standards and mission that drives your company. They will be driven to make a profit from the services that they are providing to you and other businesses like yours.

Hidden Costs. You will sign a contract with the outsourcing company that will cover the details of the service that they will be providing. Any thing not covered in the contract will be the basis for you to pay additional charges. Additionally, you will experience legal fees to retain a lawyer to review the contacts you will sign. Remember, this is the outsourcing company's business. They have done this before and they are the ones that write the contract. Therefore, you will be at a disadvantage when negotiations start.

Threat to Security and Confidentiality. The Life-blood of any business is the information that keeps it running. If you have payroll, medical records or any other confidential information that will be transmitted to the outsourcing company, there is a risk that the confidentiality may be compromised. If the outsourced function involves sharing proprietary company data or knowledge (e.g. product drawings, formulas, etc.), this must be taken into account. Evaluate the outsourcing company carefully to make sure your data is protected and the contract has a penalty clause if an incident occurs.

Quality Risk is the propensity for a product or service to be defective, due to operations-related issues. Quality risk in outsourcing is driven by a list of factors. One such factor is opportunism by suppliers due to misaligned incentives between buyer and supplier, information asymmetry, high asset specificity, or high supplier switching costs. Other factors contributing to quality risk in outsourcing are poor buyer-supplier communication, lack of supplier capabilities/resources/capacity, or buyer-supplier contract enforceability. Two main concepts must be considered when considering observability as it related to quality risks in outsourcing: the concepts of testability and criticality.

There is a strong public opinion regarding outsourcing (especially when combined with offshoring) that outsourcing damages a local labor market. Outsourcing is the transfer of the delivery of services which affects both jobs and individuals. It is difficult to dispute that outsourcing has a detrimental effect on individuals who face job disruption and employment insecurity; however, its supporters believe that outsourcing should bring down prices, providing greater economic benefit to all.

In the area of call centers end-user-experience is deemed to be of lower quality when a service is outsourced. This is exacerbated when outsourcing is combined with off-shoring to regions where the first language and culture are different. The questionable quality is particularly evident when call centers that service the public are outsourced and offshored.

Outsourcing sends jobs to the lower-income areas where work is being outsourced to, which provides jobs in these areas and has a net equalizing effect on the overall distribution of wealth. Some argue that the outsourcing of jobs (particularly off-shore) exploits the lower paid workers. A contrary view is that more people are employed and benefit from paid work. Despite this argument, domestic workers displaced by such equalization are proportionately unable to outsource their own costs of housing, food and transportation.

On the issue of high-skilled labor, such as computer programming, some argue that it is unfair to both the local and off-shore programmers to outsource the work simply because the foreign pay rate is lower. On the other hand, one can argue that paying the higher-rate for local programmers is wasteful, or charity, or simply overpayment. If the end goal of buyers is to pay less for what they buy, and for sellers it is to get a higher price for what they sell, there is nothing automatically unethical about choosing the cheaper of two products, services, or employees.

Social responsibility is also reflected in the costs of benefits provided to workers. Companies outsourcing jobs effectively transfer the cost of retirement and medical benefits to the countries where the services are outsourced. This represents a significant reduction in total cost of labor for the outsourcing company. A side effect of this trend is the reduction in salaries and benefits at home in the occupations most directly impacted by outsourcing.

Quality of service
Quality of service is measured through a
service level agreement (SLA) in the outsourcing contract. In poorly defined contracts there is no measure of quality or SLA defined. Even when an SLA exists it may not be to the same level as previously enjoyed. This may be due to the process of implementing proper objective measurement and reporting which is being done for the first time. It may also be lower quality through design to match the lower price.

There are a number of stakeholders who are affected and there is no single view of quality. The CEO may view the lower quality acceptable to meet the business needs at the right price. The retained management team may view quality as slipping compared to what they previously achieved. The end consumer of the service may also receive a change in service that is within agreed SLAs but is still perceived as inadequate. The supplier may view quality in purely meeting the defined SLAs regardless of perception or ability to do better.

Quality in terms of end-user-experience is best measured through customer satisfaction questionnaires which are professionally designed to capture an unbiased view of quality. Surveys can be one of research. This allows quality to be tracked over time and also for corrective action to be identified and taken.

Staff turnover
The staff turnover of employee who originally transferred to the outsourcer is a concern for many companies. Turnover is higher under an outsourcer and key company skills may be lost with retention outside of the control of the company.
In outsourcing offshore there is an issue of staff turnover in the outsourcer companies call centers. It is quite normal for such companies to replace its entire workforce each year in a call center. This inhibits the build-up of employee knowledge and keeps quality at a low level.

Company knowledge
Outsourcing could lead to communication problems with transferred employees. For example, before transfer staff have access to broadcast company
e-mail informing them of new products, procedures etc. Once in the outsourcing organization the same access may not be available. Also to reduce costs, some outsource employees may not have access to e-mail, but any information which is new is delivered in team meetings.

Failure to deliver business transformation
Business transformation has traditionally been promised by outsourcing suppliers, but they have usually failed to deliver. In a commoditised market where any half-decent service provider can do things cheaper and faster, smart vendors have promised a second wave of benefits that will improve the client’s business outcomes. According to Vinay Couto of Booz & Company “Clients always use the service provider’s ability to achieve transformation as a key selection criterion. It’s always in the top three and sometimes number one.” Often vendors have promised transformation on the basis of wider domain expertise that they didn’t really have, though Couto also says that this is often down to client’s unwillingness to invest in transformation once an outsourcing contract is in place.

Productivity
Offshore outsourcing for the purpose of saving cost can often have a negative influence on the real productivity of a company. Rather than investing in technology to improve productivity, companies gain non-real productivity by hiring fewer people locally and outsourcing work to less productive facilities offshore that appear to be more productive simply because the workers are paid less. Sometimes, this can lead to strange contradictions where workers in a developing country using hand tools can appear to be more productive than a U.S. worker using advanced computer controlled machine tools, simply because their salary appears to be less in terms of U.S. dollars.

In contrast, increases in real productivity are the result of more productive tools or methods of operating that make it possible for a worker to do more work. Non-real productivity gains are the result of shifting work to lower paid workers, often without regards to real productivity. The net result of choosing non-real over real productivity gain is that the company falls behind and obsoletes itself overtime rather than making investments in real productivity.

Security
Before outsourcing an organization is responsible for the actions of all their staff and liable for their actions. When these same people are transferred to an outsourcer they may not change desk but their legal status has changed. They no-longer are directly employed or responsible to the organization. This causes legal, security and compliance issues that need to be addressed through the contract between the client and the suppliers. This is one of the most complex areas of outsourcing and requires a specialist third party adviser.

Fraud is a specific security issue that is criminal activity whether it is by employees or the supplier staff. However, it can be disputed that the fraud is more likely when outsourcers are involved, for example credit card theft when there is scope for fraud by credit card cloning. In April 2005, a high-profile case involving the theft of $350,000 from four Citibank customers occurred when call center workers acquired the passwords to customer accounts and transferred the money to their own accounts opened under fictitious names. Citibank did not find out about the problem until the American customers noticed discrepancies with their accounts and notified the bank.

I already mentioned some advantages and disadvantages of Outsourcing, and in addition I will site what Insourcing and its advantages and disadvantages.

Insourcing often involves bringing in specialists to fill temporary needs or training existing personnel to perform tasks that would otherwise have been outsourced. An example is the use of in-house engineers to write technical manuals for equipment they have designed, rather than sending the work to an outside technical writing firm. In this example, the engineers might have to take technical writing courses at a local college, university, or trade school before being able to complete the task successfully. Other challenges of insourcing include the possible purchase of additional hardware and/or software that is scalable and energy-efficient enough to deliver an adequate return on investment (ROI).

Insourcing can be viewed as outsourcing as seen from the opposite side. For example, a company based in Japan might open a plant in the United States for the purpose of employing American workers to manufacture Japanese products. From the Japanese perspective this is outsourcing, but from the American perspective it is insourcing. Nissan, a Japanese automobile manufacturer, has in fact done this.

The opposite of outsourcing can be defined as insourcing. When an organization delegates its work to another entity, which is internal yet not a part of the organization, it is termed as insourcing. The internal entity will usually have a specialized team who will be proficient in the providing the required services. Organizations sometimes opt for insourcing because it enables them to maintain a better control of what they outsource. Insourcing has also come to be defined as transferring work from one organization to another organization which is located within the same country. Insourcing can also mean an organization building a new business centre or facility which would specialize in a particular service or product.

Organizations involved in production usually opt for insourcing in order to cut down the cost of labor and taxes amongst others. The trend towards insourcing has increased since the year 2006. Organizations who have been dissatisfied with outsourcing have moved towards insourcing. Some organizations feel that they can have better customer support and better control over the work outsourced by insourcing their work rather than outsourcing it. According to recent studies, there is more wok insourced than outsourced in the U.S and U.K. These countries are currently the largest outsourcers in the world. The U.S and U.K outsource and insource work equally.

If I were to choose between Outsorcing and Insourcing, my stand would be with Insourcing. On my own opinion, it is much better if the school will do insourcing due to the following reasons: the university has the capable individuals that can perform the task regarding the information system, it is safer for the university to let its own employee manage the system than letting others manipulate it, and it is also cheaper to insource because free resources are abundant nowadays. While in ousourcing, the outsourcing company will be motivated by profit. Since the contract will fix the price, the only way for them to increase profit will be to decrease expenses. As long as they meet the conditions of the contract, you will pay. In addition, you will lose the ability to rapidly respond to changes in the business environment. The contract will be very specific and you will pay extra for changes.
