Plan-Do-Study-Act (PDSA) Cycle

Shewhart Cycle

Description

Plan-do-check-act (PDCA) is a four step cycle that allows you to implement change, solve problems, and continuously improve processes. Its cyclical nature allows it to be utilized in a continuous manner for ongoing improvement.

Uses

When implementing change.

For problem solving.

For continuous improvement.

To develop a design.

How do I use this tool?

1. PLAN the change or improvement.

2. DO: Conduct a pilot test of the change.

3. CHECK: Gather data about the pilot change to ensure the change was successful.

4. ACT: Implement the change on a broader scale. Continue to monitor the change and iterate as necessary by repeating the cycle.

Expertise Required

This tool is easy to use and requires little or no training.

Advantages

Makes sure that all appropriate steps are followed.

Offers a systematic improvement method.

Is an effective process improvement guide.

Informs future improvement by providing feedback.

Maintains order during problem solving.

Disadvantages

Requires significant commitment over time.
