You will also need to determine your ultimate world-class goal or benchmark
on the OEE measure. This should not be an idle dream: rather, it should be
realistic, exacting, demanding and better than your competitors. Take each of
the three elements in turn and set your ultimate goal. There may be a strong
argument for your saying that the performance rate of the plant should be
nothing less than 100 per cent, but be realistic. Figure 3.16 shows an example

Question: What is stopping us achieving best of best consistently?
* Answer: We are not in control of the six big losses
* However: Best of best has a high belief level. Therefore teamwork and problem
solving will lead to elimination of the six big losses.
Question: What is each percentage point improvement worth on OEE?
* Answer: 5 per cent improvement in OEE is often equivalent to 25 per cent of the
annual maintenance budget
