Learn to Understand About Six Sigma

Well, our article this time will discuss six sigma in terms of definition. Of the hundreds of books on six sigma, there are many definitions described – but if we draw the conclusion line there are three fundamental things from the definition of six sigma. We discuss one by one

Six Sigma as a Measure Tool

What tools do we use if we want to know the heavier who is between you and me? right scales. If you want to know more. then the meter is the answer. The same is true if we want to compare two or more different processes and want to know which one is better performing? So six sigma is the measuring instrument.

Level how good, judging by how many products/services we produce in accordance with customer expectations, or in other words the smaller the defects generated by our process, the better our process. Statistically, six sigma means our process will not make defects more than 3.4 every one million products or services received by customers, the fewer defects you make then the higher the sigma level. To see more detail about sigma level, see table below: Sigma Defects in Percentage of defects on a million occasions:

1                              69%                                                   691,462

2                              31%                                                   308,538

3                              6.7%                                                   66,807

4                              0.62%                                                    6,210

5                              0.023%                                                    233

6                              0.00034%                                                   3.4

Six Sigma as a Methodology

In solving a problem, six sigma provides a methodology known as DMAIC, this methodology is also used by Six Sigma Black Belt Training. Define is validating the problem, Measure is measuring the problem, Analyze is looking for the source or root of the problem, Improve determines, prioritizes, and implements the solution of each validated problem, Control is keeping the applied solution running so that the problem does not reappear.

The six sigma methodology does not have to use DMAIC when you want to create a new product we know DMADV. We will discuss in more detail in subsequent articles on this methodology

Management System

The use of a consistent measurement tool will help the organization understand and control its core processes, and with systematic problem-solving methodologies will help the organization to find solutions based on the root causes. However, in reality applying the appropriate measurement tools and discipline methodology has not yet guaranteed the organization to achieve remarkable performance improvements. For that, at a higher level, six sigma can be used as a practice management system that focuses on four areas:

  • Understand who the customer is and what his needs are
  • Synchronize strategies and core processes to meet those needs
  • Use detailed data analysis to understand and minimize variations in core processes
  • Strong infrastructure, to ensure the running of improvement activities within the organization can move
  • barrier-free
