Case

Hello,I would start by clarifying what performance exactly means, as this has a huge impact on your approach.

One way of looking at it could be to measure performance as the output of good product per hour. In that case you can follow the OEE definition to structure your analysis at the highest level:

Potential production time (calendar year)
Minus availability losses (breakdowns, waiting time, etc.)
Minus performance losses (minor stops, lower speed, etc.)
Minus quality losses (scrap or re-work product)
Equals the output of good product

You can use this structure as the first level, after which you can easily add a second layer with drivers for each of the losses.

Hope this helps!
