DIS Software Development Lifecycle 3

Question 1

Which SDLC model is best suited when imaging software requirements are unclear at the outset and expected to evolve frequently?

Accepted Answer

Spiral

Answer

The Spiral model combines iterative development with risk analysis, making it suitable for projects where requirements are uncertain and may change.

Question 2

In Continuous Integration (CI) for an imaging pipeline, what action triggers an automated build and test run?

Accepted Answer

A developer commits code to the shared repository

Answer

CI systems monitor the shared repository and automatically build and test the project whenever a developer pushes a commit.

Question 3

What is 'technical debt' in the context of imaging software development?

Accepted Answer

The implied future rework from choosing quick, suboptimal solutions now

Answer

Technical debt refers to the extra work created when shortcuts or poor design choices are made to meet deadlines, requiring cleanup later.

Question 4

In the V-Model SDLC, the System Testing phase corresponds directly to which earlier phase?

Accepted Answer

Requirements Analysis

Answer

In the V-Model, System Testing validates the entire system against the original Requirements Analysis, forming the top-right arm of the V.

Question 5

A team tracks work items on a board with columns: To Do, In Progress, and Done, with WIP limits. Which methodology is this?

Accepted Answer

Kanban
