OEE ‘Waterfall’ Reports Help Make Production’s ‘Added Value’ Visible

A waterfall might appear to be an unusual model on which to base an OEE production report for the food and drink industry but when the objective of the exercise is to reduce wasted time in the production process it is a good way to visualise how well (or how badly) things are working.

 

The process is simple; the start point is a time period, illustrated in the graphic as a ‘Total Time’ of 168 hours, in a single week. In this case we don’t run the plant at the weekend so schedule ‘off’ 64 hours leaving a scheduled ‘running’ Time of 104 hours.

 

The next bar, as the waterfall cascades downwards, is the value in red, the OEE loss which in this case is 72 hours. That loss comprises the next four values: 33 hours due to Availability losses, 5 hours due to changeovers (in yellow), 33 hours due to Performance losses and 2 hours due to Quality Losses.

 

The last value represents the true point of the exercise, the discovery that out of our scheduled time of 104 hours we managed to ‘Add Value’ to the business for only 32 hours. Unfortunately we funded labour, materials and energy costs for the full 104 hours to gain those 32 hours of added value benefit.
