What is DMAIC & PDCA in Lean Manufacturing?

What is DMAIC?

DMAIC stands for Define, Measure, Analyze, Improve, and Control. The five steps define a continuous improvement cycle that should be followed in order to uncover best practices and get closer to ideal procedures.

Define

• The improvement team’s focus, scope, direction, and incentive are all defined in the project charter.
• To understand input from existing and potential consumers suggesting offerings that please, delight, and dissatisfy them by using the voice of the customer.
• A value stream map shows the entire workflow, beginning and ending with the client, and analyzes what is required to meet their needs.

Measure

• A process map is used to record the activities that are carried out as part of a process.
• Capability analysis is used to evaluate a process’s capacity to meet requirements.
• Analyze the frequency of issues or causes with a Pareto graphic.

Analyze

• Root cause analysis (RCA) is a technique for determining the root causes of a problem.
• FMEA stands for failure mode and effects analysis, and it is used to identify potential product, service, and process failures.
• To detect various types of variation inside a process, use a multi-vari chart.

Improve

• Design of experiments (DOE) is a method for resolving problems arising from complicated systems in which many variables influence the outcome and it is hard to isolate one aspect or variable from the others.
• Kaizen events are used to bring about rapid change by focusing on a specific project and utilizing the ideas and motivation of those who perform the task.

Control

• Plan for quality assurance to document what is required to maintain a better process at its current level.
• For monitoring process behaviour, statistical process control (SPC) is used.
• To design a workplace that is conducive to visual control, use the 5S method.
• To make errors difficult or instantly apparent, use mistake proofing (poka-yoke).

What is PDCA?

The Plan-Do-Check-Act (PDCA) Cycle is a four-step iterative problem-solving method for improving corporate operations. The PDCA Cycle may help a company stand out from its competitors, which is especially important in today’s business world, as companies are constantly looking for methods to optimize their operations, cut costs, raise revenues, and improve customer satisfaction.

Plan

• The framework for operations is provided by a well-defined project plan. It should, above all, reflect the mission and values of the organization.
• It should also sketch out the project’s objectives and clearly show how to achieve them.

Do

• This is the point at which the strategy is put into action.
• The strategy was devised for a reason, so it’s critical that players follow it to the letter.
• This stage is divided into three sections: training for all project participants, the actual work process, and recording insights, or data, for future evaluation.

Check

• Throughout the project, there should typically be two checks.
• First, tests during implementation guarantee that the project’s goals are met.
• Second, after the project is completed, a more extensive evaluation is conducted to identify the project’s successes and problems so that future modifications can be made.

Act

• Once prior mistakes have been discovered and rectified, the final step is to take corrective action.
• The PDCA Cycle is repeated, and under new criteria, it could be reformulated to get better results.

DMAIC vs PDCA

The main point of contention between Lean and Six Sigma practitioners is the benefits of respective problem-solving cycles. The PDCA approach is represented by Lean, but the DMAIC notion is prevalent in Six Sigma.

• PDCA appears to be a more simple and straightforward method. It is employed to address the vast majority of business issues. You may apply its problem-solving methodology at every level of your organization and solve dozens of problems every day.
• DMAIC is a more rigorous and in-depth version of PDCA. It appears to be effective at resolving large, complex problems. Problem-solving should be led by someone with technical expertise, according to the method. This worker will have at least a “green belt” qualification in Six Sigma.

They both, however, DMAIC and PDCA have a lot in common since they both are a scientific method for solving business challenges.

• They are problem-solving techniques.
• They work in a continual improvement environment.
• They go through a planning, execution, and control process.
• They employ both quantitative and qualitative techniques.

Frequently Asked Questions

Define, Measure, Analyze, Improve and Control, the five steps of a continuous improvement cycle. Define sets the team's focus and scope in a project charter, listens to the voice of the customer and maps the value stream. Measure records the process and its capability and ranks problems on a Pareto chart. Analyze finds root causes with RCA, FMEA and multi-vari charts. Improve runs design of experiments and kaizen events. Control holds the gain with SPC, 5S and poka-yoke.

Plan-Do-Check-Act is a four-step iterative method for solving problems and improving operations. Plan sets out the project's objectives and how to reach them, in line with the organization's mission and values. Do puts the plan into action, with training for participants, the work itself and recording of data for later evaluation. Check tests during implementation and again after completion to find successes and problems. Act takes corrective action and starts the cycle again under new criteria.

PDCA belongs to lean and DMAIC to Six Sigma. PDCA is the simpler and more direct method, used for the great majority of everyday business problems, and anyone at any level of the organization can apply it to solve several problems a day. DMAIC is the more rigorous, in-depth cycle for large, complex problems, and the method expects it to be led by someone with technical training, at least a Six Sigma green belt.

Both are scientific methods for solving business problems, so they share more than they differ. Each is a problem-solving technique, each works inside a continual improvement environment, each moves through planning, execution and control, and each uses quantitative and qualitative tools. The choice between them comes down to the size of the problem and the expertise available, with PDCA for daily issues and DMAIC for big projects.

Four appear most often. A quality assurance plan documents what is required to keep the improved process at its new level. Statistical process control monitors process behaviour over time so drift is caught early. The 5S method organizes the workplace for visual control, so abnormalities show at a glance. Mistake proofing, or poka-yoke, redesigns the step so errors are hard to make or instantly obvious when they happen.
