Welcome to DMAIC

DMAICSix Sigma takes a handful of proven methods and trains a small cadre of in-house technical leaders, known as Six Sigma Black Belts, to a high level of proficiency in the application of these techniques. The tools are applied within a simple performance improvement model known as DMAIC, or Define-Measure-Analyze-Improve-Control. DMAIC can be described as follows:


Define the goals of the improvement activity. At the top level the goals will be the strategic objectives of the organization, such as a higher ROI or market share. At the operations level, a goal might be to increase the throughput of a production department. At the project level goals might be to reduce the defect level and increase throughput. Apply data mining methods to identify potential improvement opportunities.


Measure the existing system. Establish valid and reliable metrics to help monitor progress towards the goal(s) defined at the previous step. Begin by determining the current baseline. Use exploratory and descriptive data analysis to help you understand the data.


Analyze the system to identify ways to eliminate the gap between the current performance of the system or process and the desired goal. Apply statistical tools to guide the analysis.


Improve the system. Be creative in finding new ways to do things better, cheaper, or faster. Use project management and other planning and management tools to implement the new approach. Use statistical methods to validate the improvement.


Control the new system. Institutionalize the improved system by modifying compensation and incentive systems, policies, procedures, MRP, budgets, operating instructions and other management systems. You may wish to utilize systems such as ISO 9000 to assure that documentation is correct.

DMAIC Problem Solving Worksheet, is a step by step problem solving methodology to statistical find the real causes of problems. The ChartitNOW package contains a DMAIC Problem Solving Template.

DMAIC Problem-Solving Course Outline -- 2 Units

Unit 1 - Getting Started Lesson 1: Becoming Aware of a Problem. · Ways to recognize indications of problems. · Ideas to help decide which problems to work on first. Lesson 2: Why Use a Structured Problem-Solving Process? · How a formal problem-solving approach can improve the effectiveness of the whole organization. · Building a common problem-solving language. Lesson 3: Do You Need a Team? · Five questions to determine which problems need a team and which problems one person working alone can effectively handle. Lesson 4: The Importance of Data. · How data leads to information and information points the way to knowledge. · Subjective versus objective data. · Attribute data versus variable data. · Using data to infer and make judgments. Lesson 5: Overview of Different Problem-Solving Models. · 8-Discipline Problem-Solving Model. · DMAIC Project Cycle. · Xerox Problem-Solving Process. · Boeing Process Flow for Working Projects. · A generic Six-Step Problem-Solving Model. Challenge: An assessment of the learner's progress in this unit.

Unit 2 - DMAIC Project Cycle Lesson 1: Define. · Establishing a project (problem-solving) team and getting the team started up. · Developing the Problem Statement. Lesson 2: Measure. · Setting up the measurement systems so that the appropriate data needed to determine the root cause of the problem can be collected. Lesson 3: Analyze. · Using a systematic approach to collect, display, and analyze data to identify the root cause(s). · Verifying that the cause identified is truly the root cause. · Identifying a solution to attack the root cause and correct the problem. Lesson 4: Improve. · Executing the problem solution. · Developing simple and complex action plans. · Using Gantt and PERT Charts to plan the implementation and monitor progress. Lesson 5: Control · Finishing the job to ensure the problem does not come back. · Ensuring training, audit practices, and knowledge transfer are completed. Challenge: An assessment of the learner's progress in this unit.
