Use of Short-run Statistical Process Control Techniques: A Comparison of JIT and Non-JIT Manufacturing

The purpose of this paper is to compare the implementation of short-run (i.e., small lot-size) statistical process control (SPC) techniques for manufacturing between the U.S. and Japan. Using U.S. and Japanese questionnaires, this research focuses on the use of several manufacturing management elements such as setup time, stability of process, and quality improvement. These elements are compared in terms of their respective countriesÕ short-run SPC techniques implementation. Barriers to the implementation of short-run SPC techniques are also examined. In addition, this research identifies current process control techniques used to support short-run SPC in both countries. Results show how the significantly different short-run SPC techniques are utilized in the U.S. and Japan.
