Overall Equipment Effectiveness (OEE) 
Case Study at Oscar Mayer

Overall Equipment Effectiveness (OEE)

In this case study, The Lean Group supported the factory management team to implement aom1.gif system of OEE (Overall Equipment Effectiveness) measurement across 3 factories. The aim of this programme was to enable them to accurately identify the potential for capacity increase and labour cost reduction within the 3 factories on the Chard site.

Analysis of the main downtime losses in all factories Indicated that product changeover and line clean down accounted for 80% of the total lost time.

om2.gifA study team comprising line leader, operators and supervision Studied the actual changeovers– using video and stopwatch, enabling them to fully understand the sequence of the changeover and the critical factors that would ensure a hygienically clean line.

Having understood the current situation, a number of improvement actions were identified that would significantly reduce the unnecessary motion required during the changeover activity.

These ranged from making cleaning materials more accessible to a full analysis of the man assignment and work content for each operator.om3.gif


A new procedure was written and all staff trained before re-studying the changeover.

The results of these activities across the three factories have been significant as can be seen from the chart on the right.

Oscar Mayer are now able to more confidently achieve the Daily volumes despite significant fluctuations in daily requirements.
