CAD Agile Development Practices 4

Question 1

Which Agile technical practice focuses on keeping the design as simple as possible and deferring decisions until the last responsible moment?

Accepted Answer

Simple Design / Emergent Design

Answer

Simple or emergent design means designing only for current needs, letting the architecture evolve with refactoring rather than over-engineering upfront.

Question 2

What is a 'spike' in Agile development?

Accepted Answer

A time-boxed research or prototyping task to reduce uncertainty

Answer

A spike is a time-boxed effort—typically a prototype or research task—used to gain knowledge needed to estimate or implement a story with confidence.

Question 3

In Agile, which metric best indicates the sustainable pace of a team?

Accepted Answer

Average velocity over several sprints

Answer

Average velocity across multiple sprints reflects a team's sustainable pace and is the most reliable input for release forecasting.

Question 4

Which practice best supports the Agile principle of 'responding to change over following a plan'?

Accepted Answer

Using short iterations with frequent reprioritization of the backlog

Answer

Short iterations with frequent backlog reprioritization allow teams to incorporate new information and changing priorities at low cost.

Question 5

What is 'refactoring' in Agile development?

Accepted Answer

Restructuring existing code without changing its external behavior to improve quality

Answer

Refactoring improves internal code structure—readability, maintainability, or design—without altering the software's observable behavior.
