COMP1531 - Requirement Engineering

What is a fundamental difference between the Waterfall and Agile software development methodologies?

• Waterfall is iterative and flexible, while Agile is sequential and rigid.

• Waterfall is best suited for projects with fixed requirements, whereas Agile is more adaptable to changing requirements.

• Agile prioritizes extensive documentation, while Waterfall focuses on working software.

• Agile involves a single, large development cycle, while Waterfall uses multiple short cycles.

Which of the following is the correct sequence of phases in the Waterfall Software Development Life Cycle (SDLC)?

• Requirements, Design, Implementation, Testing, Deployment, Maintenance

• Planning, Analysis, Implementation, Testing, Maintenance, Deployment

• Design, Requirements, Testing, Implementation, Deployment, Maintenance

• Analysis, Planning, Design, Implementation, Testing, Deployment

In the context of the Waterfall development model, if features, time, and cost are fixed, which aspect is typically compromised?

• Scope

• Quality

• Resources

• Schedule

In the Agile approach, if cost and time are fixed, what becomes the variable aspect that can be adjusted?

• Quality

• Budget

• Features

• Schedule

Why are robust deployment strategies crucial for large-scale software systems like social networks or banking systems?

• To reduce the overall development cost.

• To minimize the impact of potential bugs or failures on a large user base.

• To accelerate the initial development phase.

• To simplify the codebase for easier maintenance.

The "Canary Release" deployment strategy is named after the historical practice of using canaries in coal mines. What does this analogy signify in software deployment?

• The software is expected to sing praises if successful.

• A small, sensitive part of the system is deployed first to detect potential issues.

• The deployment process is highly automated and requires minimal human intervention.

• The software is designed to be lightweight and consume minimal resources.

What is the primary purpose of A/B testing in software deployment?

• To ensure all users receive the latest software version simultaneously.

• To compare different versions of a feature to determine which performs better based on user data.

• To gradually release new features to a small subset of users for initial feedback.

• To maintain two identical production environments for immediate failover.

In A/B testing, how are users typically divided to evaluate different versions of a feature?

• Into a development group and a testing group.

• Into a control group (original version) and a treatment group (new version).

• Into an alpha group and a beta group.

• Into a front-end group and a back-end group.

What is the primary purpose of A/B testing in software development?

• To ensure all users receive the same software version simultaneously.

• To compare different versions of a feature to determine which performs better based on user data.

• To detect bugs and performance issues in a production environment before full release.

• To gradually roll out new features to a small group of users to minimize risk.

Which of the following is a common performance measure used in A/B testing to evaluate feature effectiveness?

• Number of lines of code written.

• Developer's subjective opinion.

• Number of clicks needed to reach a certain point.

• Time taken to compile the software.
