Module 2 – Case
NET-CENTRIC COMPUTING AND INFORMATION SYSTEMS
Case Assignment
The idea of Net-Centric computing is a relatively recent formulation, although in many ways it revisits the old architecture of mainframes and terminals. This netcentriccomputing.org definition is short and to the point:
“The underlying principle of Net-Centric Computing (NCC) is a distributed environment where applications and data are downloaded from servers and exchanged with peers across a network on as as-needed basis. This is in stark contrast to the use of powerful personal computers that rely primarily on local resources. In some respects, NCC resembles an earlier computing era of mainframes and centralized services. However, there are significant differences. For example, NCC relies on virtually portable applications running on multiple platforms, mobile data accessed via high-speed network connections, and low-cost appliances for local processing. In many ways, NCC is the enabling technology for a significant percentage of modern enterprise applications.”
It is clear that this perspective commands a lot of interest and has some powerful forces behind it, not the least of which is the US Department of Defense. But it is also clear that like many powerful concepts, it is capable of being interpreted in so many different ways that its functional meaning is frequently obscure. To say, as one analyst has described it, that “the underlying principle of net-centric computing is that of an intelligent distributed environment where applications and data are available on demand” is to promise a great deal, but none of it particularly specific.
As in so many other areas, the problem is that systems have to be to be used by people. James Robertson has written a provocative article on 10 principles of effective information management (KM. 1 November 2005), that cogently describes what might be described as “people-centric” concerns, that constitute the day-to-day preoccupations of IT managers.
Your task in this module is to bring net-centric ideas to these people-centric problems. When you have reviewed the material in the background information regarding Net-Centric computing and related issues, and consulted any other material that seems helpful to you, please write a 3-5 paper discussing the question:
Analyze and discuss how Robertson’s 10 principles apply in the context of a computer network.
Assignment Expectations
Your paper should be 3–5 pages. Take a definite stand on the issues, and develop your supporting argument carefully. Using material from the background information and any other sources you can find to support specific points in your argument is highly recommended; try to avoid making assertions for which you can find no support other than your own opinion.
You will be particularly assessed on:
Precision: Your draw on a range of sources, and to establish your understanding of the historical context of the question. You carried out the exercise as assigned, or carefully explained the limitations that might have prevented your completing some parts (running out of time isn’t generally considered an adequate limitation).
Support for assertions: You use examples, citations (especially to the required readings), and elaboration to support assertions. You provide evidence that you have read the required background materials.
Clarity: Your answers are clear and show your good understanding of the topic. You see what the module is all about and to structure your paper accordingly.
Breadth and Depth: The scope covered in your paper is directly related to the questions of the assignment and the learning objectives of the module.
Critical thinking: The paper incorporates YOUR reactions, examples, and applications of the material to business that illustrate your reflective judgment and good understanding of the concepts. It is important to read the “required readings” posted in the background material plus others you find relevant. Your informed commentary and analysis is vital — simply repeating what your sources say does not constitute an adequate paper.
Overall quality: Your paper is well written and the references, where needed, are properly cited and listed (refer to the Student Guide to Writing a High-Quality Academic Paper) if you are uncertain about formats or other issues.
