Detailed Explanation:
The correct answer is B. Prioritization matrix.
A prioritization matrix is specifically designed to compare options against selected criteria and rank them in a structured way. In this case, the company wants to evaluate improvement initiatives based on impact and feasibility, which makes the prioritization matrix the most suitable tool.
A prioritization matrix helps teams:
Compare multiple alternatives
Apply weighted criteria if needed
Rank projects or actions objectively
Focus effort on the most beneficial initiatives
This is especially useful when resources are limited and not all initiatives can be pursued at once.
Why the other options are incorrect:
A. Affinity diagram
An affinity diagram is used to organize large amounts of ideas or data into related groups. It helps with categorization, not ranking.
C. Activity network diagram
An activity network diagram is used for scheduling and sequencing activities in a project, not for selecting among improvement options.
D. Tree diagram
A tree diagram breaks broad goals into smaller tasks or levels of detail, but it is not primarily a ranking tool.
