Which SDLC phase encompasses activities such as OS updates, bug patches, and performance tuning after the imaging software is in production?
Answer: Maintenance
The Maintenance phase covers all post-deployment activities including corrective, adaptive, and perfective changes to keep the software operational.
A digital imaging team uses pair programming, test-driven development, and continuous refactoring. These practices belong to which Agile framework?
Answer: Extreme Programming (XP)
Extreme Programming (XP) prescribes engineering practices including pair programming, TDD, and continuous refactoring to improve software quality.
What is the primary goal of a sprint retrospective in an Agile imaging project?
Answer: Identify what went well and what to improve in the team's process
The sprint retrospective is a team ceremony focused on continuous process improvement by reflecting on the just-completed sprint.
In risk management during the SDLC, what does 'risk mitigation' mean?
Answer: Taking proactive steps to reduce the likelihood or impact of a risk
Risk mitigation involves implementing actions before a risk materializes to reduce its probability or minimize its potential impact on the project.
Which metric measures the number of story points a Scrum team completes per sprint, used to forecast future delivery?
Answer: Velocity
Velocity is the average number of story points a team completes per sprint and is used to predict how much work can fit in upcoming sprints.
A developer writes a test for an imaging color-conversion function before writing the function itself. This approach is called:
Answer: Test-driven development (TDD)
Test-Driven Development (TDD) follows a red-green-refactor cycle where tests are written first, the code is written to pass them, then refactored.
In which SDLC document are the system's inputs, outputs, processes, and data stores typically modeled using Data Flow Diagrams (DFDs)?
Answer: System Design Specification
DFDs are created during the System Design phase and documented in the System Design Specification to illustrate how data moves through the system.
