A look at six sigma methodologies
The structure of Six Sigma is to get as close to perfection as possible. Therefore, companies measure how many defects are in a process and then narrow them down to achieve perfection. In order for a company to achieve Six Sigma, it cannot produce more than 3.4 defects per million opportunities, where an opportunity is defined as a chance for nonconformance.
Six Sigma asserts the following:
The Six Sigma Methodologies The breakdown for the acronym is as follows: The DMADV methodology is geared towards creating new products and business practices. The breakdown for the acronym is as follows: The main thing that makes both processes stand out is the Define step. This step proves that the customer satisfaction is the most important factor. The Define stage calls for baselining and benchmarking the process to be improved. The similarities between the two processes are as follows:
There are many key differences between the processes as well. DMAIC should be used when a product or process is in existence, but not meeting expectations. DMADV should be used when a product or process is not in existence and needs to be developed or an existing product is developed and has been optimized with DMAIC and is still not meeting requirements. Six Sigma proponents claim that its benefits include up to 50% process cost reduction, cycle-time improvement, less waste of materials, a better understanding of customer requirements, increased customer satisfaction, and more reliable products and services. One firm, Computer Sciences Corporation (CSC) helped a U.S. government agency "increase customer satisfaction and save approximately $2.8 million." They implemented a Quality Management System that entails document control, quality assurance processes, and information assurance certification and delivery coordination. CSC also reported helping another client save more than $1 million for helping to reduced time in service requests and data analysis. DMAIC, DMADV or any other method of Six Sigma will yield results if implemented as required. Not only will your company save money, but the outcome of other processes will be pleasing.
