Software Engineering Practice Questions Part 1

Which of the following is not part of a formal/tabular use case description? a. actor b. scenario c. exception d. stakeholders

stakeholders

Give two of the most representative characteristics of agile process in comparison to traditional process models.

Examples: customer being part of the team; quick response to changes; emphasis on customer communication; frequent delivery of product; trustworthy customers; senior development team, etc

The goal of software process is high quality. Why does better quality imply better timeliness?

In short, the reason is that lower quality usually leads to rework. Higer quality implies less rework then better timeliness.

Is quality assurance an umbrella activity or framework activity?

It is an umbrella activity as it applies throughout software process

What are the major differences between the incremental model and the spiral model?

Structure/process flow: evolutionary versus incremental Deliverable: partial versus early Focus: risk reduction/quality control versus delivery of operational product

Compared to sequential process, all iterative process models have a common strength concerning risk. What is it and why do all iterative models have this strength?

The strength is risk reduction, because an iterative process allows iterations hence enabling adoption of feedbacks and revisions/corrections. As such, errors can be discovered and fixed earlier thus risk can be reduced

Which of the following UML diagrams are used in scenario-based modeling? a. class diagrams b. state diagrams c. activity diagrams d. swimlane diagrams e. state diagrams and activity diagrams f. activity diagrams and swimlane diagrams

Which of the following describes software process incorrectly? a. the iterative process flow generalizes the evolutionary process flow. b. all umbrella activities are always evenly applied across software process. c. in the spiral model, each iteration (cycle) must end up with working software. d. all umbrella activities are always evenly applied across software process and in the spiral model, each iteration (cycle) must end up with working software e. all umbrella activities are always evenly applied across software process, in the spiral model, each iteration (cycle) must end up with working software and in the spiral model, each iteration (cycle) must end up with working software.
