Maintenance and Reliability 
(#10 of 10 Strategic OM Decisions) – ch. 17

A good maintenance and reliability strategy protects both a firm’s performance and its investment.  The object is to maintain the capability of the system while controlling costs.  Good maintenance drives out variability.  Maintenance includes all activities involved in keeping a system’s equipment in working order.  Reliability is the probability that a machine part or product will function properly for a specified time under stated conditions.

This chapter examines four tactics – two involve reliability (improving individual components) and providing redundancy) and two involve maintenance (implementing or improving preventative maintenance and increasing repair capabilities or speed.  Top firms build and maintain systems so that customers can count on products and services that are produced to specifications and on time.

Final Topic:  Forecasting – ch. 4

Forecasting is the art and science of predicting future events – is often a mathematical model adjusted by a manager’s good judgment.  There are both qualitative and quantitative forecasting techniques.  Qualitative approaches employ judgment, experience, intuition, and a host of other factors that are difficult to quantify.  Quantitative forecasting uses historical data and causal, or associative, relationships to project future demand.  Because of the complexity of the calculations and the often large amounts of data, operations managers turn to software packages like Forecast PRO, SAP, tsMetrix, AFS, SAS, SPSS and Excel.
