ORIGINAL COMPANY-CONTEXT PRACTICE
Keep an equipment-work approval valid after the plan changes
Original practice scenario: A hypothetical energy-site planning application routes a work package for review. The equipment scope changes after approval. Design version and authorization checks.
Written for independent practice using company context; this is not a verified question from a company interview.
A REASONED APPROACH
Model answer.
Bind an approval to a specific plan version and scope. A historical signature must not silently authorize later changes to the equipment, time window or work description.
Work through it
- Model the work package as versioned data with identified reviewers, approved scope and decision timestamps; preserve superseded versions for audit.
- Classify which edits invalidate which approvals, rechecking authorization and required reviews before the updated package may be released.
- Use optimistic concurrency or another explicit conflict mechanism, with idempotent decision records and tests for simultaneous edits, revocation and expired time windows.
Tradeoffs to discuss
- Fine-grained approval reuse avoids repeated review but requires a defensible dependency model; invalidating every edit is simpler while creating more workload.
Common pitfalls
- The application should support an approved operational process rather than claim to establish site safety by itself.
- Never authorize execution merely because a user opened an approved version earlier.
