Preventive Maintenance Procedures Flashcards

When a legacy system has no documentation, which approach helps recover its requirements?

Answer: Reverse engineering of existing behavior, code and usage combined with stakeholder input

Requirements for legacy systems are recovered by analyzing artifacts and behavior and validating with stakeholders.

What is a key advantage of reusing well-maintained requirements across projects?

Answer: Reduces effort and increases consistency

Reuse saves effort and promotes consistent quality, but reused items still need validation.

Which lifecycle consideration applies to requirements during product operation?

Answer: They must be kept current as the product evolves and new releases are planned

Requirements remain a living reference throughout the product lifecycle.

What does a requirements glossary contribute to long-term maintenance?

Answer: It prevents terminology drift and misunderstandings over time

A maintained glossary keeps shared terminology consistent as the team changes.

Which practice supports knowledge preservation when team members leave?

Answer: Keeping rationale and decisions documented alongside requirements

Documented rationale lets successors understand why decisions were made.

In an agile context, how is the product backlog maintained as a living requirements artifact?

Answer: It is regularly refined, reprioritized and pruned

Backlog refinement continuously updates and reprioritizes items.

Which is the best reason to archive rather than delete obsolete requirements?

Answer: It preserves history for audits and later reference without cluttering active requirements

Archived items remain retrievable for traceability and audits while the active set stays clean.
