In the Plan-Do-Check-Act cycle, what is the primary purpose of the 'Plan' phase?

• A. Plan changes to improve quality
• B. Do implement
• C. Check evaluate results
• D. Act adjust or standardize based on findings

Answer: (A)

Plan is where you design the improvement: decide exactly what changes to try, why they should improve quality, and how you will implement them. It involves outlining objectives, selecting the changes to test, detailing steps, assigning responsibilities, setting a timeline, and deciding what data or metrics will show whether the change works. This preparation creates a concrete plan that can be put into action in the next phase and guides how success will be measured.

The other phases serve different roles: implementing the plan is the Do step, evaluating results is the Check step, and adjusting or standardizing based on findings is the Act step.
