Understanding Increments in Scrum
An Increment is a key concept in Scrum, representing a concrete step toward the final product. Here’s an analysis of an exam question related to identifying an Increment:
Exam Question
Which of the following is an example of an Increment? (choose the best answer)
- A. A plan for the overall product release.
- B. A mock-up of the product marketing materials.
- C. A design for the product.
- D. A product roll-out plan.
- E. A valuable, useful set of product features.
- F. All of the above.
Correct Answer
E. A valuable, useful set of product features.
Explanation
Why E is Correct
An Increment in Scrum is defined as a concrete step forward in the product’s development, resulting in a potentially shippable product that adds value. It must be a complete, usable piece of the product that can be inspected and potentially released.
Key Points about Increments:
- Value Addition: Increments represent valuable, usable sets of product features that provide actual value to the stakeholders or end-users.
- Potentially Shippable: An Increment must be complete and meet the Definition of Done, making it potentially shippable even if it is not actually released.
- Inspectable: Each Increment should be inspectable, allowing stakeholders and the Scrum Team to review and provide feedback.
Examining the Other Options
A. A plan for the overall product release: While important, a release plan is not a tangible product feature that can be delivered to stakeholders. It does not meet the criteria of being a potentially shippable product increment.
B. A mock-up of the product marketing materials: Mock-ups are preliminary designs and not a working product increment that provides value in terms of functionality.
C. A design for the product: A design is a blueprint for development but is not a functional piece of the product itself. It does not provide direct value to end-users in terms of functionality.
D. A product roll-out plan: Similar to a release plan, a roll-out plan is a strategic document and not a tangible increment of the product.
F. All of the above: This option is incorrect as only one of the choices (a valuable, useful set of product features) truly represents an Increment in the Scrum sense.
Roles and Responsibilities in Scrum
- Developers: Work to create potentially shippable increments each Sprint, ensuring that each Increment meets the Definition of Done.
- Scrum Master: Facilitates Scrum events and helps the team adhere to Scrum practices, ensuring that Increments are delivered effectively.
- Product Owner: Prioritizes Product Backlog items to ensure that each Increment delivers maximum value to stakeholders.
Relevance to the PSM I Exam
Understanding what constitutes an Increment is crucial for the PSM I exam. This knowledge helps candidates recognize the importance of delivering complete, usable product features that add value. Mastery of these concepts is essential for effectively implementing Scrum practices and achieving certification.
Conclusion
An Increment in Scrum is a valuable, useful set of product features that meet the Definition of Done and are potentially shippable. Understanding this concept is crucial for success in the PSM I exam and for the effective implementation of Scrum practices.
