The mean reason that OEE has developed into an accepted and valuable Key Performance Indicator is the fact that performance is measured against the actual capacity of the segment we are measuring with OEE and not against others. Measuring against others might give us a subjective view of our performance compared to how the rest is doing but it would fail to give us the information we actually need to be able to improve: How are we performing within the provided capacity? OEE tells you, when done properly of course, without any dilution how the performance was during any given moment in time compared with the actual capacity for that time. Due to Availability% * Quality% * Rate% against Capacity the Performance was xx% of the available capacity. This gives us the opportunity to look at the total OEE and the individual loss categories, do detailed analyses of the causes and implement improvements based on facts.
So why not do the same with IQ/EQ/SQ and measure the actual performance against the actual capacity of oneself? Not against others, not against what others tell us what the capacity should be. Just against our own true capacity as we see it, as we feel it. Measure our performance against our very own best we can be. I suggest we try this in the same manner we work with OEE.
- Step 1: Make a realistic estimate of your capacity as a human being within your organization as a professional and as an individual in your private environment.
- Step 2: Establish your peak performance under optimal conditions, just as we do to establish the peak performance to measure OEE against, of course for the combination of your professional and personal life.
- Step 3: Keep a daily diary of your performance and losses for a period of 2 weeks and attempt to objectively determine which factor and influence kept you from reaching your 100%.
- Step 4: Evaluate your findings with someone you trust. This could be your partner, your coach, your peer, anyone you feel totally confident with to give insight in your personal thoughts and observations.
