Deck 32: Process and Project Metrics

Question 1

What are four useful indicators of software quality that should have measures defined and monitored by the software project team?

Answer 1

correctness,maintainability,integrity,usability

Question 2

What are the goals for using object-oriented software metrics?

Answer 2

-To better understand product quality
-To assess effectiveness of the process
-To improve the quality of work performed at the project level

Question 3

Explain how size-oriented metrics differ from function-oriented metrics.Discuss the pros and cons of each.

Answer 3

Size-oriented measures are computed by normalizing direct measures of the software engineering process (e.g.effort or defects)over the product size,measured in lines of code.Function-oriented measures are indirect measures that are computed from measures of the information domain of a business application and an assessment of its complexity.Size-oriented metrics are relatively easy to collect,but can present problems when component-based or visual programming methods are applied.Function-oriented metrics can be determined much earlier in the software cycle,but are an abstraction that is open to interpretation.

Question 4

Why is it important for software developers to make use of measurement to guide their work?

Question 5

How do software process metrics differ from software project metrics?
