Cusum modelling of the dynamics of process performance improvement programmes

Abstract

Purpose

To evaluate the Cusum model as a means of rapid trend detection and dynamic response classifier in a low signal/noise environment.

Design/methodology/approach

The method used was the design and implementation of an IT system for automatic on‐line monitoring of press operator performance.

Findings

Operators engaged following an in‐house skills enhancement programme display a wide range of performance profiles.

Research limitations/implications

Identifies opportunities for further management investigation of working practices identified as leading to regression plus operators obviously learning to “work smarter, not harder”.

Practical implications

A range of novel performance templates based on the Cusum model have been derived and tested on 18 press operators.

Originality/value

The Cusum model is already well established in the literature. This case study shows that the model can be readily exploited via automatic operator performance monitoring and subsequent classification.
