Zhang Chi Consulting Group believes that where there is a process, there is a six-sigma map. In manufacturing, people always focus on optimizing product quality; In the service industry, people pay attention to customer relationship. The application of Six Sigma to enterprises can be summarized as follows: (reducing costs, improving productivity, increasing market share, retaining customers, shortening cycle time, reducing defects, changing corporate culture, improving products/services, and enhancing the comprehensive competitiveness of enterprises. )
Zhang Chi Consulting Company provides open six sigma courses and project consultation (six sigma, lean six sigma, design for six sigma, lean production).
