INTRODUCTION

When six sigma or six sigma's processes refer to a concept that states one aspiration or goal in common when it comes to quality for processes of an organization. The term is first used in the 1980-1989 decade and gave its name to the improvement program six sigma. Through the concepts seen before is easy to analyze and understand the level of quality in term of the number of sigmas.

It was started in Motorola in 1987 by engineer Bill Smith, as a business strategy and improving quality, but later improved and popularized by General Electric. The cost to train a person in Six Sigma is largely compensated by the benefits gained future. Motorola claims to have saved 17,000 million since its implementation, so many companies have decided to adopt this method.

5S was developed in Japan and was identified as one of the techniques that enabled Just in Time manufacturing.

Two major frameworks for understanding and applying 5S to business environments have arisen, one proposed by Osada, the other by Hirano. Hirano provided a structure for improvement programs with a series of identifiable steps, each building on its predecessor. As noted by John Bicheno, Toyota's adoption of the Hirano approach was '4S', with Seiton and Seiso combined. Although the origins of the 5S methodology are in manufacturing, it can also be applied to knowledge-economy work, with information, software, or media in the place of physical product.

OBJETIVES

GENERAL:

• To know the concept of six sigma and the 5s methodology and how are they important inside an organization that adopts them.

SPECIFIC:

• Establish the tools that the six sigma methodology uses to evaluate the quality of an organization.

• Define each one of the 5s from the 5s methodology.

• Define the number of sigmas and organization has according to its efficiency.

SIX SIGMA

Is a process improvement methodology, focused on reducing the variability of them, getting reduce or eliminate defects or failures in delivery of a product or service to the customer. 6 Sigma's goal is to reach a maximum of 3.4 defects per million events or opportunities (DPMO), meaning any default event a product or service fails to meet customer requirements.

• Six Sigma's aim is to eliminate waste and inefficiency, thereby increasing customer satisfaction by delivering what the customer is expecting.

• Six Sigma follows a structured methodology, and has defined roles for the participants.

• Six Sigma is a data driven methodology, and requires accurate data collection for the processes being analyzed.

• Six Sigma is about putting results on Financial Statements.

• Six Sigma is a business-driven, multi-dimensional structured approach for:

o Improving Processes

o Lowering Defects

o Reducing process variability

o Reducing costs

o Increasing customer satisfaction

o Increased profits

The word Sigma is a statistical term that measures how far a given process deviates from perfection.

The central idea behind Six Sigma: If you can measure how many "defects" you have in a process, you can systematically figure out how to eliminate them and get as close to "zero defects" as possible and specifically it means a failure rate of 3.4 parts per million or 99.9997% perfect.

Obtain 3.4 defects in one million of chances is a very ambitious goal, but reachable. There can be classified the efficiency of a process based on its number of sigmas:

• 1 sigma= 690.000 DPMO = 31% of efficiency

• 2 sigma= 308.538 DPMO = 69% of efficiency

• 3 sigma= 66.807 DPMO = 93,3% of efficiency

• 4 sigma= 6.210 DPMO = 99,38% of efficiency

• 5 sigma=
