Six sigma 6σ
The applied method, called DMAIC (Define, Measure, Analyze, Improve, Control), uses statistical tools, as well as devices to observe the process variables and relationships that help them manage their properties.

What is Six Sigma?

Six sigma is arevolutionary approach to measuring and managing quality improvement has become a reference method for the same time, meet customer needs and achieve to levels close to perfection. But what exactly is Six Sigma?

Simply put, is a method, based on data, to bring quality to levels close to perfection, unlike other approaches as it also corrects problems before they arise. More specifically it is adisciplined effort to examine the repetitive processes of companies.

Literally any company can benefit from Six Sigma process. Design, communication, training, production, management, losses. All fall within the field of Six Sigma. But the road is not easy. The possibilities for improvement and cost savings are enormous, but the Six Sigma process requires a commitment of time, talent, dedication,persistence and, of course, economic investment.
A typical cost of quality non-errors, defects and loss-processes can account for 20 to 30per 100 of sales. The field is wide, even without reaching the level Six Sigma (3.4 errors or defects per million opportunities), the ability to significantly improve the results are limit less. Only necessary that the organization makes available to itscapabilities and proceed in a manner consistent with its resources.

The beginning

It is essential that the commitment to the Six Sigma approach begins and remains in the top management of the company. Experience shows that when the address does not express his vision of the company, does not convey strength and enthusiasm, not evaluate the results and does not recognize effort, improvementprograms become a waste of valuable resources. The Six Sigma process begins with the awareness of executives to reach a common understanding of the Six Sigma approach and to understand the methods that will allow the company to achieve quality levels hitherto unsuspected

The next step is the selection of employees, professional capacity and responsibility in their areas or functions that willbe intensively trained to lead improvement projects. Many of these employees will have to devote a significant portion of their time to projects, if you intend to significant results.

The formation of these leaders takes place in four sessions of four days each, over a period of 12 weeks during which they will work on a specific project for improvement, which will enable candidates to a newprofession, "black belts" as implementers of these advanced quality initiatives. This training, taught by experts, including the selection of a project in the first week and the application of learning to the project before the next session, by an improvement team.

To reach the level "black belt" candidates have to demonstrate the results achieved at the project level and this enables them to continue tolead new teams for new improvement projects.

The method

The Six Sigma method, known as DMAIC, is the application, project to project, a structured process in five phases.

In the definition phase identifies any potential Six Sigma projects to be evaluated by management to avoid under-utilization of resources. After selecting the project prepares its mission and select the most suitableequipment for the project, giving it the necessary priority.

The measurement phase is to characterize the process by identifying the key customer requirements, key features of the product (or outcome variables) and parameters (input variables) that affect the functioning of the process and the characteristics or variables
key. From this characterization is defined as the system and measure...
