IT and Business Architecture/PLZ i need your help


What is the purpose of a computer aided decision support system? What are the major components of such a system? How does it help the decision making process?

2.    What are the determinants of MIS design according to Zani? Explain the following statement, “there is a two way relationship between organization and Information Systems”.

3.   What is computerized maintenance management? Explain the conceptual model through which the maintenance function can achieve its objectives on a sustained

4.   In which phase of system life cycle the following are performed? Defining the problem, indentifying its causes, specifying the solution, and identifying the information requirements.

5.   What are expert systems? Mention the working principles of expert systems. Also discuss how knowledge can be represented in expert systems.

1. a. Computer aided decision support is largely the reporting front ends on top  enterprise data warehouse which you can apply what-if questions to to determine courses of action based on past experiences.
b. As stated a data warehouse, an analytics engine and reporting tool.
c. see answer a.

2. a. I am not familiar with Zani.
b.  Information Systems are reflective of Organizations, they capture the functional  activities, and interaction of an organization with all of its business parties (employees, customers, suppliers, regulators, etc).

3. This is an archival of the assets, inventory, tools and schedules of all maintenance required. The system then does a predict analysis based on use and or time of the planned/scheduled maintenance and couples this to the predictive planning based on mean time to failure for replacement.

4.  If you know what a virtuous circle is then in every stage we identify and then determine if they are issues, bugs or merely functionality to be explained.  Then most software has a planned release schedule (biannual major releases, semi-annual bug fixes; for example) these elements are then included into them along with a road map designed around the business change and development cycle.

5. Expert systems are usually the same analytics from question 1, that are specifically tuned to critical business processes.  Good examples, are sale/market planning and forecasting systems, transportation infrastructure modeling systems ( how to route ships/plans in a disaster).

I truly felt these were interview type questions.  Each of these would have a myriad of more sub questions in areal interview so I suggest you research them online to get the most complete answers and good luck with the interview.
