CHAPTER 1 The Software Life Cycle 5
Review Questions
1. How does a phased life cycle model assist software management?
2. What are two required characteristics of a milestone?
3. For each of the following documents, indicate in which phase(s) of the software life
cycle it is produced: final user manual, architectural design, SQA plan, module specification,
source code, statement of work, test plan, preliminary user manual, detailed
design, cost estimate, project plan, test report, documentation.
4. Order the following tasks in terms of the waterfall model: acceptance testing, project
planning, unit testing, requirements review, cost estimating, high-level design, market
analysis, low-level design, systems testing, design review, implementation, requirement
specification.
5. Draw a diagram that represents an iterative life cycle model.
Answers to Review Questions
1. How does a phased life cycle model assist software management?
The phased life cycle improves the visibility of the project. The project can be managed
by using the phases as milestones. More detailed phases will allow closer monitoring of
progress.
2. What are the two required characteristics of a milestone?
A milestone (1) must be related to progress in the software development and (2) must
be obvious when it has been accomplished.
3. Documents in the software life cycle:
Final user manual Implementation phase
Architectural design Design phase
SQA plan Project planning phase
Module specification Design phase
Source code Implementation phase
Statement of work Feasibility phase
Test plan Requirements phase
Preliminary user manual Requirements phase
Detailed design Design phase
Cost estimate Project planning phase
Project plan Project planning phase
