Variation reduction

We strive to deliver high-quality products that result in consistent performance for our customers. Minimizing variation in our products, processes and raw materials is critical to achieving this goal. Our variation reduction processes and projects protect customers from product variation.

The variation reduction program focuses on implementing and improving quality-related processes that protect customers from product variation and on identifying and reducing sources of product variation. This includes rigorous use of statistical process control (SPC), a robust change management process, strong supplier management and a Six Sigma culture that strives to eliminate variation.

Supplier Management

Our supplier management is a collaborative process owned by our supplier quality and sourcing teams with significant input from R&D. The foundation of our supplier management process is built on the high expectations of the semiconductor industry and includes key components such as:

Change Management

Process Control Systems

Business Continuity Plans

Continuous Improvement

Supplier Scorecards

Supplier Audits

Supplier Awards


Each of these components, and more, are integrated into a closed loop process which follows the Six Sigma DMAIC structure of: Defining the expectations, Measuring and Analyzing supplier performance, Improving suppliers through continuous improvement, and then Controlling the supply base through approved supplier ratings and integration into new product development.

Six Sigma

It is our commitment to offer the highest quality, lowest variation products which is why we’ve incorporated Six Sigma into our culture. Six Sigma is the practical application of statistical tools and methods to help us define, measure, analyze, improve and control our processes. This proven methodology reduces variation, enhances process knowledge and directs our focus onto customer performance.
