Module 2: Assessment (Graded) » Week 2 » Reviews & Metrics For Software Improvements

Q: List the types of software peer reviews in order from the least formal types of reviews to most formal types of reviews:

Correct. Software walkthroughs are informal “show-and-tells”, while software technical reviews address technical aspects of the product. Software inspections find and fix defects in word products according to rigid structures.

Q: The peer review techniques that involve assessing requirements based on the criteria of: ambiguity, consistency, and completeness are (Choose two that apply):

This is a correct answer because in a requirements technical review, reviewers examine requirements written by the author in order to identify defects, using all of the requirements criteria to help identify high-risk areas. This includes not only ambiguity, consistency, and completeness, but correct, clear, verifiable, feasible, traceable, manageable, and simple.

Q: Some common reasons software projects may avoid using metrics include (select all that apply):

This is a correct answer because projects usually have a limited amount of time, so any time spent on things other than coding can seem like a waste of time, leading to skipped metrics. This is a danger of Agile, since Agile focuses on fast and efficient development, so metrics can seem especially undesirable.

Q: The Goal, Question, Metric paradigm helps alleviate the following issues surrounding metrics (Choose two that apply):

This is a correct answer because the development team better understands what they are measuring and why through the establishment of a goal and related questions, the metric will be more effective if GQM is used.

Q: Gabriela is working on a piece of software that will help a concert venue sell tickets. The clients would like to provide customers with free shipping of tickets if they spent over $250.00. Gabriela will use this number in her code to change shipping to $0.00 – if the number is under $250.00, then the customer has to pay for shipping. The number $250.00 is an example of:

Correct. An indicator is a measure that informs the numbers in some way. In this case, $250.00 and above indicates that the customer should not pay shipping fees.

Q: Examples of desirable properties of metrics include (Choose two that apply):

This is a correct answer because a metric should have a steady, consistent definition of what is being measured.

Q: The popular uptime metric measures in percentages how long a product is “up” and available to users. What requirement does this measure?

Correct. The longer a product is “up” and available to users, the more reliable it is.

Q: Which of the following are properties of defect analysis? (Choose three that apply)

This is a correct answer because software barrier occur when the number of defects create is the same as the number of defects fixed. A subsystem with a software barrier should get more focus from the team.
