Measurement of the maintenance process from a demand‐based perspective

Abstract:

While various figures have been published on the workload distribution of maintenance activities, this information is at best indicative of management perceptions, most of it originating from surveys, and almost none based on actual data. The reason for such a lack of published data is very simple: the industry does not measure or collect maintenance‐type data in a timely and accurate fashion. This article presents empirical data from a two‐year measurement effort in the maintenance environment of a Canadian financial institution. The findings reported here are based on a daily data‐collection process including 2152 work requests, which required 11 332 days to complete. Based on the supply/demand paradigm, maintenance data have been collected and analysed to investigate the basis of productivity analyses through such concepts as the product group, the product mix and the product mix changes on the demand side, as well as resource allocation by product classification and quarterly and yearly distribution changes. This paper includes a discussion on the measurement program implemented, and illustrates how insights into the maintenance process are gained through various measurements. The paper also presents hard data on the demand side and on the supply side of the maintenance process, as well as an analysis of the data collected. The findings reported are part of a larger measurement program introduced to manage the maintenance area in the same way as any other business unit. Copyright © 1993 John Wiley & Sons, Ltd
