Six Sigma is a business strategy developed in the 1980s at Motorola and systematically aims to improve the processes within a business or organization. It initially was developed to focus on reducing defects in the products produced but has evolved over the years and now includes improved product/service quality, customer satisfaction, and productivity. By adopting this stratagem, organizations can hope to achieve significantly larger output both quantitatively and qualitatively.
The key to success in six sigma involves multiple factors.
1. The DMAIC methodology/program is one of the key factors that often ensures a successful six sigma implementation. DMAIC refers to define, measure, analyze, improve and control. This step-by-step approach forms one of the core philosophies of six sigma which is to continuously lower defects in products/services and reduce variation in processes.
2. Another core philosophy of six sigma is providing optimum customer satisfaction. Six sigma theories believe that customer satisfaction is directly related to the defects in a product/service and the cost of operating it. Thus eliminating defects in products/services serves to improve customer satisfaction directly according to six sigma values.
3. Senior management needs to be mandatory involved in showing support to six sigma initiatives in person. They need to be involved directly in various six sigma activities such as:
4. Customizing six sigma programs in order for them to be aligned with an organization’s broader policy and long-term goals. This will further improve efficiency in the implementation of the six sigma programs. In order to do this, organizations may hire a six sigma consultant to impart training to team members. The training must be flexible and time-bound to avoid producing inadequately trained members who will become a liability in deploying six sigma programs.
These factors listed above account for most of the major factors crucial to the success in deploying a six sigma program in an organization.
