Lean and Six Sigma are both process methodologies used by companies that are usually in the manufacturing or services sector. Both seek to improve production processes and delivery of products and services. There are major differences however in the approaches of the two methodologies. But in essence, the final goal of Lean and Six Sigma is to upgrade the efficiency of production processes to make products competitive and reduce production cost.
Lean methodology is an ideal process flow improvement for increasing the speed of production and delivery of products. The focus of Lean is to accelerate the process with minimum or zero waste. In this way, production or service costs can be significantly reduced therefore increasing profit margins and improving customer satisfaction.
Six Sigma on the other hand, focuses on eliminating defects in the process and seeks to elevate the quality of producing and delivering products. By eliminating defects and mistakes in the flow of production, companies can increase the viability of their products. Therefore, it can effectively compete with others which will result to increasing profit.
Companies with inefficient work flow processes, undisciplined organization, and sub-standard quality control can be overhauled using Lean and Six Sigma principles. These measures can ensure that companies can survive in the world market by instituting world class production processes.
The application of combined Lean and Six Sigma methodologies in the production processes of companies can have powerful impact in their productivity, efficiency, and profitability. More companies now are adopting the Lean and Six Sigma principles in order to compete effectively in the global market.
