IPA IP 2023 Question 54

Topic: Project Management

A question IPA Japan published in 令和5年度 ITパスポート試験 公開問題 問54, translated into English. ITPEC is based on the same exams.

Same question on ITPEC: Oct 2024 Q51

Among the descriptions A through D below concerning project management in system development, which of the following lists all and only the failures in scope management?

A:The labor costs incurred in development were underestimated, so the budget was exceeded.B:The time required for development work was set short, so development could not be completed within the planned period.C:A project was started without first deciding the function to be created, so the development period is exceeded.D:Several activities that should be implemented in a project were omitted from the plan, so the system could not be completed.

Explanation

C, D — both fail to define the work the project must deliver, which is what scope management does.

  • •A Underestimated labor costs overrun the budget: a cost management failure.
  • •B Too little time set for the work misses the planned period: a schedule management failure.
  • •C Starting without deciding which functions to build leaves the product scope undefined: a scope failure.
  • •D Omitting required activities from the plan leaves the project scope (the WBS) incomplete: a scope failure.

Answer (d)

Why not others:

  • •(a) A, B — both are cost and schedule failures, and neither scope failure is listed
  • •(b) B, C — includes B, a schedule estimate, and omits D
  • •(c) B, D — includes B, a schedule estimate, and omits C

Key rule: Classify a failure by its cause, not its symptom: C also overran the period, but the root error was undefined scope, not a bad time estimate.
