Quality and productivity improvement using DMAIC methodology in a functional test station in a production line.

Abstract

In a competitive world as ours, companies of all business types must maintain two key points as their main metrics, these are productivity and quality, these two have a direct proportional relationship, if one goes down the other will also do so in the same magnitude. It is known that quality in goods and services is one of the main factors sought by companies, but in many cases having or maintaining a level of quality considered good is achieved at a high cost due to the large amount of waste and rework that exists and as we mentioned, it directly affects productivity since in order to meet the requirements, more resources must be invested in the manufacturing of the goods. In order to remain in the competitive business environment, the company must improve and maintain the quality and productivity in its processes, then they must work on solving problems related to these two metrics, hence the use of methodologies for solving problems is the best way to contribute to increase the performance of quality and productivity levels. Having trained employees capable of solving problems through a methodology is an excellent investment in the short and long term. The six sigma methodology with its DMAIC structure has shown great versatility of use, from a beverage industry to an automotive company, or in the administrative sector, its structure is well received for solving problems, improving the main competitiveness metrics of any company, guides the teamwork in a practical and methodological way to reach the root cause and the real solution of the problem, eliminating waste and increasing profits. The key to the success of any company is quality and productivity in all of its processes.
