Professional Scrum Master I (PSM I) — Question 109

Which of the following best describes an increment of working software?

Answer options

• A. A decomposition of all Product Backlog items into tasks for future Sprint Backlog lists.
• B. Additional features in a usable state that complement those delivered in previous iterations.
• C. A new user interface design for functionality delivered in previous iterations.
• D. An automated test suite to verify functionality delivered in previous iterations.
• E. UML diagrams that describe how to deliver functionality in future iterations.

Correct answer: B

Explanation

The correct answer, B, highlights that an increment consists of new features that are in a usable state, building upon previously delivered work. Options A, C, D, and E describe elements that do not represent an increment of working software, as they focus on breakdowns, redesigns, validation, or planning rather than the addition of usable features.
