Lean Problem-Solving

Correct Answer: Clarify and validate the problem definition

In the lean problem-solving approach, the first step is always to 'Clarify and validate the problem definition'. This aims to understand the root cause of the problem rather than rushing to develop solutions for the perceived problem. When we understand the problem correctly, only then can we devise an appropriate strategy to solve it. On the other hand, 'Increase project budget', 'Replace the existing team with a new team', or 'Change the project’s schedule randomly' are not ideal first steps. Increasing the budget or replacing the team might not solve the problem if the root cause is not correctly identified and understood. Moreover, changing the schedule randomly can lead to chaos and confusion, adding more problems instead of solving the existing ones.

Correct Answer: Identify the root cause of the problem

The best approach to solve a problem according to Lean problem-solving principles is to identify the root cause of the problem. This technique emphasizes on understanding the underlying issues that cause inefficiencies or problems, and focusing on addressing these root causes rather than putting a temporary fix. The other answers are not aligned with Lean principles: 'Switch to a more easy-going project' and 'Work overtime to meet the deadline' only avoids or masks the issue rather than truly solving it, and 'Ask your team to figure it out themselves' does not demonstrate the collaborative problem-solving approach promoted by Lean.

Correct Answer: Identify the key constraints in communication, gather more data to understand the root cause, and then apply the most fitting solution.

The best answer is 'Identify the key constraints in communication, gather more data to understand the root cause, and then apply the most fitting solution.' This approach aligns with Lean Problem Solving which promotes identifying constraints, understanding the root cause, and finding the best solutions. 'Start by implementing a new communication tool without understanding the root cause.' is an incorrect choice because it's jumping into a solution without understanding the problem first. Similarly, 'Fire the team members who are ineffective communicators.' is counterproductive, as it does not solve the root cause. It might even create a fearful environment thus hindering open communication. Lastly, 'Ignoring the problem as if it doesn't exist' is never a solution since it allows the problem to persist and possibly worsen over time.
