Software Engineering

1. Assume the table below defines the activities for a small project. Task Dependencies A B C D E F G H Completion time (days) 7 5 4 3 3 6 8 6 A B CD F E, G a. A Network Diagram (i.e. Pert Chart) is commonly used when applying the Critical Path Method to a project. Based on your diagram, what is the critical path for this project? b. How many weeks will it take to complete the project if everything stays on schedule? c. How many weeks can task E be delayed (if any) without causing the overall project to go off schedule? d. Expand your Pert Chart into a full network diagram that shows the earliest start time, earliest finish, late start, late finish, and float for each task. 2. How are software effort and cost estimates made when using experience-based techniques? 3. How are software effort and cost estimates made when using algorithmic cost modeling? 4. What approaches can be used to estimate lines of code for a system? 5. Briefly discuss why accurate code sizo estimates are difficult to make at the beginning of a project
