Turn OEE into a financial indicator

Three steps to calculate the value of measuring effectiveness.


Overall Equipment Effectiveness (OEE) is one of the best indicators of process reliability, but many struggle to connect OEE to the bottom line. How much of an OEE improvement is necessary? How aggressive does my reliability improvement program need to be? Turning OEE into a financial indicator helps us translate these questions into business decisions.

First, if not familiar with OEE, here are the basics:

  • OEE is the product of Uptime, Operational Efficiency, and First Pass Quality (FPQ).
  • OEE measures the effectiveness of a process, or a grouping of assets, when utilized.
  • OEE tells us, as an organization, how well we executed our asset management plans.
  • OEE is the result of losses that impact the desired performance of the process.

Turning OEE into a financial indicator is easier than you think.

  1. Calculate or record the total revenue, or contribution margin, recognized for the time period.
  2. Next, divide the total revenue by the number of OEE points for the same time period. For example, if you recorded an OEE of 63% at the end of July then you would divide your July revenue by 63 points.

Assume, for a moment, that the current OEE is 63% and desired target is 85%. The difference is 22 OEE points. Now take the value of 1 OEE point and multiply it by the difference between the current and target OEE. That's the potential financial value of OEE improvement.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
