What are the steps of the PDCA Cycle?

1. PLAN  

2. DO  

3. CHECK  

4. ACT  

PLAN :

Identify the Problem :

• Identify the problem that needs to be solved
• Make a problem statement to define the problem
• Make SMART goals ( Specific, Measurable, Achievable, Realistic & Time-bound)
• Identify the Team.

Analyze the Problem:

• Check the process flow of the complete process or system.
• Do brainstorming for the possible causes.
• Analyze data to validate the root cause.
• Revise the problem statement if required.

Tools used for the Plan step :

• Process Flow Diagram
• Process Mapping
• Cause & Effect diagram
• Pareto Chart

DO :

Develop Solutions:

• Do that activity or experiment
• Do design of experiment (DOE)
• Discuss with the team for a solution to get the right solution.

Implement the solution :

• Implement the solution on a trial basis.

Tools used for DO steps :

• Cross-Functional Team (CFT)
• Design of Experiment (DOE)
• Provide training about the work 

CHECK :

Verify the results:

• Analyze the result of the solution
• Validate the result

Achieve the required Goal :

• If the goal has been achieved, then go to ACT
• If the goal is not achieved, go to PLAN, and revise the problem/actions.

Tools used for CHECK steps:

• Control Charts
• Key performance indicator (KPI)
• Process observation

ACT :

Implement the Solution :

• Identify the systematic changes.
• Training needs identification (TNI)
• Plan continuous monitoring of the solution.
• Do Kaizen in the process.

Tools used for ACT steps:

• Standardization of work & process
• Do Poka Yoke
• Process Mapping
• Provide regular training
