1: What are the legal and ethical implications of using COTS software? Of using subcontractors? For example, who is responsible for fixing the problem when the major system fails as a result of a fault in COTS software? Who is liable when such a failure causes harm to the users, directly (as when the automatic brakes fail in a car) or indirectly (as when the wrong information is supplied to another system). What checks and balances are needed to ensure the quality of COTS software before it is integrated into a larger system?
2: Draw a diagram to capture the process of buying an airplane ticket for a business trip.
3: Consider the Software Life-Cycle Models introduced. Which one give you the most flexibility to change in reaction to changing requirements?
Why can a count of faults be a misleading measure of product quality?
4.Why can a count of faults be a misleading measure of product quality?
5: Even on your student projects, there are significant risks to finishing your project on time. Analyze your software development project and list the risks. What is the risk exposure? What techniques can you use to mitigate each risk?
6: CPM Problem
Assume that for “company A” a number of processes should be conducted for risk management process. The process is reflected by the graph below (Critical Path).
Note: Each number represents the total days required to finish the particular job.
- Which path is the critical path?
- What is the minimum of number days required to finish the whole task?
- Fill out the table.
| Path | Slack Time |
| A..B | |
| C..E | |
| D..F | |
| E..F | |
| E..H | |
| G..H | |
| J..H | |
| H..I |
7: Suppose as your project supervisor, I want you to estimate effort required to build a 10,000 lines of code.
- Calculate the effort (in person-months) based on Walston/Felix model. Round it to closest whole (integer) number
- Calculate the effort (in person-months) based on Bailey/Basili model. Round it to closest whole (integer) number
8: Your project manager has developed a new technique for estimating project size. He has been using this new technique for variety of projects and his estimates and the actual values for project size are shown below. Use the project size estimates and the criteria given to answer the questions.
Project Estimate Actual
A 7800 8000
B 9000 9500
C 7000 7100
D 28000 25000
E 8000 8600
- Given the estimates and actuals, what is the MMRE? Round to the nearest 1/100.
- What is the PRED ?
