Information sytems lecture agenda Sept 7
Main topics in Sept 7 lecture of IS
A. Probability/ Impact Grid in Risk Analysis
B. Investment appraisal and Requirement Determination
1. 4 appraisal techniques: payback method, accounting rate of return, NPV, IRR\
- Accounting rate of return:
(average annual accounting profit/ average investment) x 100%
Average investmnet = (initial investment + scrap value)/ 2
2. Comparison of NPV and IRR
3. Business requirements and user requirements
* Business requirments
* User requirements: functional requirements and non-functional requirements
4. Requirement determination
* What is a requirement

* Requirement analysis techniques: BPA, BPI and BPR
- Business Process Automation: leave the basic way in which the organization operates unchanged. Techniques: problem analysis, root cause analysis
- Business Process Improvement: make moderate changes in business operation; techniques to use: Duration analysis, Activity-based costing, Informal benchmarking
- Business Process Engineering: change business operation in a fundamental way; techniques to useL outcome analysis; technology analysis; activity elimination
* Requirement gathering techniques: Interviews, JAD, Questionnaires, Document Analysis; Observations
- Interview steps: (1) select interviewees, (2) designing interview questions, (3) preparing for the interview; (4) conducting the interview; (5) postinterview follow-up
Joint Application Development:
- role of the facilitator: set agenda; ensure to stick to the agenda; explain technical terms to participants; record and show group's inputs in a public display area

- role of Groupware: eJAD
