PMI Professional in Business Analysis (PMI-PBA) — Question 135

In the first few weeks after a large implementation of a new web-based application, a critical report failed. Further investigation determined that a worker had been using a field that was not supposed to be used. This issue was not identified in testing.
Which technique could have prevented this problem from occurring?

Answer options

• A. Prototyping
• B. Use cases
• C. Document analysis
• D. Diagrams

Correct answer: B

Explanation

Use cases provide a detailed description of how users will interact with the application, helping to clarify requirements and identify potential misuse of fields. In this scenario, proper use case analysis could have highlighted the restrictions on field usage, preventing the issue. The other options, while useful, do not focus specifically on user interactions in the same way that use cases do.
