In the preferred calculation, you get the best of both worlds. This is the role of Availability, Performance, and Quality. What your OEE score doesn’t provide is any insights as to the underlying causes of lost productivity. And it makes it easy to track improvements in that process over time. OEE scores provide very valuable insight – an accurate picture of how effectively your manufacturing process is running.
And, as described earlier, multiplying Good Count by Ideal Cycle Time results in Fully Productive Time (manufacturing only Good Parts as fast as possible, with no Stop Time). This is the “simplest” OEE calculation described earlier. OEE = (Good Count × Ideal Cycle Time) / Planned Production Time
