C. Start-Start

D. Finish-Finish

Which of the following is correct?

A. It is OK to include QUI details when writing a use case

B. We invite the clients to attend both the sprint review and retrospective meeting at the end of a sprint

C. We break a use case into tasks during the release planning meeting

D. Waterfall process can be very useful when the requirements are stable and well-defined

Free Response : What are the 4 design activities in software engineering?

Database, Interface, Architecture, and Component Design

Free Response : List one advantage and one disadvantage of the waterfall model.

Advantages : useful when requirements are clear and stable

Disadvantages : difficult for customer to state all requirements explicitly, working software comes later, not good when requirements change

Free Response : Why do we need to prioritize requirements?

Software requirements are important because they clearly define what a system must do and reduces the risk of error and project failure.

Free Response : List 4 agile practices.

The Planning Game, Simple Design, Pair Programming, 40-Hour Work Week, Small Releases, Continuous Testing, Collective Code Ownership, On-Site Customer, System Metaphor, Refactoring, Continuous Integration, Coding Standards

Free Response : During requirements elicitation, a stakeholder says, “The system should generate reports quickly and accurately.” Identify 2 potential ambiguities in this requirements and explain how you would clarify or refine it.

Both “quickly” and “accurately” are vague. Ask stakeholder to explain more specifically what they expect. Provide a measurable value for how quick (3 seconds, 1 minute, 5 minutes). What percentages of accuracy are they looking for?

Free Response : What is the difference between product backlog and sprint backlog?

Product Backlog are the requirements the product should have

Sprint Backlog are the tasks created from the list of requirements

Free Response : List 2 techniques used to determine if a use case is written at the right abstraction level.

The Boss Test, Elementary Business Process Test (EBP), The Size Test

Free Response : Why do we need prototyping?

Prototyping provides a good visual to show the clients so that they can actually see the progress. It is much easier to show a working visual prototype than to show the clients code, which they may not understand.

Free Response : What is the purpose of writing Vision and Scope documentation?

A Vision and Scope document defines the overall goals, boundaries, and requirements of a project so there is a clear understanding of what the system will accomplish.

Free Response : Recall the Software Iron Triangle. What is the main takeaway from this triangle.

The Software Iron Triangle consist of Scope, Resources, and Schedule where all 3 determine the quality of the project. The main takeaway is what a company or client prioritizes.
