Article Abstract

This abstract is an edited version of the author's original.

This is a continuation of Quality Function Deployment (QFD) on a Defense Contract. This installment examines the application of Total Quality Management (TQM) to the latter stages of a project. It discusses Statistical Process Control (SPC) and how QFD and Design of Experiments (DOE) help implement SPC. The goal of the project is to develop a factory to build high-rate, low-cost microwave hybrids for the aerospace, automotive, and defense industry.

Implementing a successful SPC program on the production floor requires many TQM tools. The process includes three basic steps:

  1. setting the foundation,
  2. establishing controls, and
  3. making sure that these controls meet our needs and our customer's needs.
  • Step 1 talks about the use of QFD and DOE to define the best manufacturing approach, select the best equipment, and fingerprint that equipment so precontrols can be put on each process.
  • Step 2 discusses how to go from precontrol to full-fledged control charts; it also covers the need to establish Process Action Teams, Process Control Logs, Out of Control Condition Procedures, and risk assessments.
  • Step 3 looks at ensuring that the controls in place meet our needs and the needs of our customer.
The Hughes Aircraft Company develops partnerships with vendors through the GM Targets for Excellence system. This system provides a method for continuous improvement at the vendor level so all can benefit.
