Task Based Techniques. DMAIC model for “six sigma methodology” Ibrahim tag
Task Examples in this report isn’t all tasks done in each phase, but it’s just examples for such a model tasks. There are other several tasks and tools used in this model.

Task Based Techniques.
Introduction The main purpose of the report is to define task based techniques used in quality improvement methodologies like six sigma, reengineering and kaizen ……etc. The focus of this report is on techniques used in tasks involved with DMAIC model (solving problem method) which used as a project manager for the six sigma methodology to make a quality improvement for a certain process. Six sigma methodology as a definition is using the statistical approaches to reduce failures in processes and making the defects per million opportunities just 3.4 defects by controlling the process limits and make it all the time within the specification limits with 1.5 sigma shift and it’s a breakthrough improvement. Six sigma is using DMAIC model to achieve that goal. DMAIC model consists of five phases: 1. 2. 3. 4. 5.
Define Measure Analyze Improve Control
And each phase contains many tasks which are accomplished by several techniques with supportive tools and indicators.

Task Based Techniques.
Define the problem. •
Task: identifying the problems. Technique: Pareto analysis.
•
(Pareto principle states that in any population that contributes to a common effect, a relative few of the contributors—the vital few—account for the bulk of the effect. The principle applies widely in human affairs.) Tools: Pareto chart.
•
Indicator: priority of improving a specific
•
problem.
•
Task: define the customer. (Who is the customer?) Technique: brain storming.
•
(Brainstorming is a group creativity technique designed to generate a large number of ideas for the solution of a problem.) Tools: team members, check sheets and questions ….etc.
•
Indicators: stakeholders.
• •
Task: define the project. Technique: project charter.
•
(The project charter includes the project justification, the major deliverables, and the project objectives. It forms the basis of future project decisions, including the decision of when the project or subproject is complete.) Tools: project charter worksheet.
•
Indicators: the scope and the vision of the project.
•

Task Based Techniques.
• •
Task: identifying root causes. Technique: cause and effect analysis. (This is a graphical method of showing the relationship between cause and effect. Each type of nonconformity (an effect) would be analyzed to postulate the causes so.)
• •
5
Tools: fishbone diagram. Indicators: the effective causes of the problem.
Task Based Techniques. Measurement of process parameters: • • • •
• • •
Task: Temperature measurement. Technique: direct measurement. Tool: thermocouple or thermometer. Indicator: temperature.
Task: dimension measurement. Technique: direct measurement. Tools: vernier caliber and micrometer ……etc.
•
Indicator: dimensions (diameter , length and height …...Etc.)
Analyze the process • • • •
• • • •
6
Task: process capability measurement. Technique: statistical. Tools: measuring DPMO and other factors. Indicator: process performance.
Task: find the effective parameters. Technique: statistical. Tool: Design of experiment. Indicators: process performance.
Task Based Techniques. Improve the process: • • • •
• • • •
7
Task: reducing non-value added activities. Technique: work break down structure. Tools: flowchart of the current process. Indicator: sequence of the process.
Task: create future state process map. Technique: brainstorming. Tools: process mapping and flowchart. Indicator: performance of the improved process.
Task Based Techniques. Controlling the process • • • •
Task: controlling the process. Technique: statistical. Tools: process charts. Indicators: process performance.
