Six Sigma is a methodology for solving and preventing quality problems. The ultimate goal here is to (almost) always meet the requirements or specifications of the customer; such a process produces less than 3.4 deviations per million possible deviations (0.00034%). Six Sigma is an improvement methodology introduced by Motorola, but put in the spotlight by General Electric. Today, the method is not only used by many large companies such as Essent, Heijmans, Rabobank, MSD, but it is also widely used in small and medium-sized enterprises.
Quality problems often cause major problems at a later stage in the overall process. For example, products have to be returned or services have to be delivered again, resulting in extra work for those who have to fix the problems. Because the problems have to be solved in addition to the 'regular' work, the workload is increasing. When the workload becomes too high, even more quality problems will arise, because work is done in a rush. Subsequently, more problems have to be repaired and a vicious circle has developed. A quality problem must therefore be tackled at the earliest possible stage. We are therefore convinced that the application of Six Sigma in your processes will be very beneficial.
The step-by-step plan used at Six Sigma is abbreviated with DMAIC, which stands for:
