To answer this question, you need to understand the DMAIC (Define, Measure, Analyze, Improve, Control) methodology, which is a problem-solving approach used in Six Sigma.
In the DMAIC methodology, the phase where brainstorming for solutions occurs is the "Improve" phase. This is the phase where potential solutions are identified, evaluated, and selected to address the root causes of the problem identified in the previous phases.
Let's go through each option to understand why it is correct or incorrect:
Option A) Control - This option is incorrect because the control phase focuses on implementing and sustaining the selected solution, rather than brainstorming for solutions.
Option B) Measure - This option is incorrect because the measure phase focuses on collecting and analyzing data to understand the current state of the process, rather than brainstorming for solutions.
Option C) Analyze - This option is incorrect because the analyze phase focuses on identifying the root causes of the problem, rather than brainstorming for solutions.
Option D) Improve - This option is correct because the improve phase is where brainstorming for solutions occurs. In this phase, potential solutions are generated, evaluated, and selected to address the root causes identified in the analyze phase.
The correct answer is D) Improve. This option is correct because the improve phase is where brainstorming for solutions takes place in the DMAIC methodology.
