PSM I - Kaizen Example Questions

Test your knowledge of Kaizen

Question 1

You, as a ScrumMaster, have identified some areas for potential improvements. When would you suggest these during the Kaizen event?

After each team member has had an opportunity to share their own suggestions and ideas. Before the Kaizen event to pre-influence the team's thoughts. At the start of the Kaizen event to guide the discussion. Immediately after the Sprint Review meeting, before the Kaizen event.

Correct Answer: After each team member has had an opportunity to share their own suggestions and ideas.

The best answer possible is 'After each team member has had an opportunity to share their own suggestions and ideas'. The essence of Scrum and likewise Kaizen events is collaboration and team involvement. It would be more effective if the ScrumMaster allows each team member to share their suggestions and ideas first before suggesting their own. This ensures that everyone's thoughts are heard and taken into consideration before any changes are implemented. The other answers suggest timing that could potentially rob team members of their opportunity to share or influence their thoughts. For example, suggesting improvements at the start could guide the discussion in a biased way. Suggesting improvements before the event could pre-influence the team's thoughts, and suggesting immediately after the Sprint Review might not give team members enough time to consider their own suggestions and ideas.

Question 2

During a Kaizen event, a team member suggests an improvement that was previously tried and failed. As a ScrumMaster, how should you respond?

Allow the team member to implement the idea without a team discussion. Immediately dismiss the idea as it was unsuccessful in the past. Ask the team member to come up with a new suggestion instead. Discuss the suggestion, why it failed previously, and explore if any changes could lead to a different outcome.

Correct Answer: Discuss the suggestion, why it failed previously, and explore if any changes could lead to a different outcome.

The fundamental concept of the Kaizen is continuous improvement. If a team member suggests an improvement that was previously tried and failed, it doesn't mean that it should be outrightly dismissed as it might work under different circumstances or with some modifications. This matches the option 'Discuss the suggestion, why it failed previously, and explore if any changes could lead to a different outcome.' And that's why it's the correct answer. On the other hand, the other options do not encourage open discussion and learning from past failure, which contradicts the principles of Kaizen and Scrum. 'Immediately dismiss the idea as it was unsuccessful in the past.' This response is dismissive, closes off potential learning opportunities, and discourages team members from sharing their ideas. 'Allow the team member to implement the idea without a team discussion.' This response doesn't promote the idea of collaboration, ignores potential input from other team members, and misses an opportunity to learn from past mistakes. 'Ask the team member to come up with a new suggestion instead.' This response is also dismissive and discourages learning from past failures.

Question 3

During a Kaizen event, the team identifies a process that could significantly improve efficiency but would require a substantial initial investment. The stakeholders are hesitant to allocate the necessary funds. As the ScrumMaster, what should be your approach?

Facilitate a cost-benefit analysis with the team and stakeholders, highlighting the long-term benefits of the improvement. Encourage the team to find alternative solutions that achieve similar efficiency gains without requiring substantial upfront costs, even if they may not be as effective. Defer the decision to the stakeholders and move on to other potential improvements that don't require significant investment. Implement the improvement without stakeholder approval, as the long-term benefits outweigh the initial cost.

Correct Answer: Facilitate a cost-benefit analysis with the team and stakeholders, highlighting the long-term benefits of the improvement.

As a ScrumMaster, the best approach is to facilitate a cost-benefit analysis with the team and stakeholders, highlighting the long-term benefits of the improvement. This allows for a data-driven discussion about the potential return on investment, addressing stakeholder concerns while advocating for process enhancements that can significantly boost efficiency. Deferring the decision entirely to stakeholders may cause the team to miss out on valuable improvements. Implementing the change without approval undermines trust and collaboration. Encouraging alternative solutions is good, but if the identified improvement is truly the most effective, it's worth making a strong case for it.
