Introduction

Some organizations experience problems implementing Statistical Process Control despite insistence from customers demanding higher quality. For example, one common problem is the small production lot sizes. Traditional SPC charting does not work well with the short-run processes, and this situation creates frustration for these manufacturers. This problem is understandable-- indeed, traditional charts are NOT designed to work with short production runs (i.e JIT Manufacturing Environment).

Generally, SPC charts require a long, continuous and homogeneous process to be most effective, whereas most job-shop and companies practicing Just In Time (JIT) manufacturing have short production runs of many different products. This scenario creates legitimate problems for a JIT organization that desires to implement traditional SPC charts.

This seminar provides the solution to this vexing problem and covers other innovative methods that settles all the irregular problems associated with the use of traditional SPC charts. By utilizing special data transformation formulas, the short-run charts allow users to plot all the various part-number products to run through the process on a single control chart. Furthermore, this method reduces time consuming paper work, and increases the effectiveness of the process control.

Because all process data rests on a single chart, control limits can be determined sooner (with some charts almost immediately) as compared to traditional SPC charts. Users can interpret the chart in a real-time mode, while parts still are being run. Since all process data is plotted on the same chart, interpretation of time-related process changes (like runs, trends, cycles ..etc.) becomes possible. The user can now control the process as well as part number.

In this training, various short-run charts appropriate for different short-run environments will be discussed. Examples and case studies from various job shops and companies using JIT manufacturing will be presented and analyzed. Also included are tips and suggestions for successful implementation of short-run charts ( as well as traditional charts) including where to begin, what to chart, how to select suitable chart, subgroup size, sampling frequency for a given process and when to recalculate the control limits.

Target Audience

1) Those responsible for implementing SPC ( Engineers and Managers) as well as those in the production line who actually do the charting in-job shops or Companies practicing JIT, Group technology, or lean manufacturing techniques.

2) Quality Engineers/Managers and Suppliers Quality Engineers/Managers responsible for helping their short run-suppliers implement SPC or JIT for the purpose of quality improvement and cost reduction.

Prerequisite
The participants should have a basic knowledge of SPC and Control Chart Concept.
