The power of PDCA is its simplicity and cumulative improvement possibilities by continually repeating the cycle, done either by the same team or other teams.

PLAN: Start with the expected results in mind. Establish the objectives and processes required to attain the expected results.

DO: Implement the new process. Start small at first to test the new idea.

CHECK: Measure the new process relative to the expected results.

ACT: Analyze the differences and root causes by comparing current best practice versus new ideas to understand specific opportunities. Each cause should be the beginning of another PDCA, resulting in further improvement.
