I'm creating a performance metrics for the quality of my team's work towards certain assessment document.
Assuming we have a way to measure the value of X's, we can assign overall 'quality' of each document.
I set up the quality criteria to be below:
X1: If the document is reviewed by team of 4
X2: If the document filled out every sections
X3: If the document is approved on time (Assuming target duration is 90 days, so we want the document to be approved within 90 days)
I assigned the weights to X's, and they are: X1=0.5, X2=0.25, X3=0.25. (Assuming X1 is most important, and X2, X3 are equality important)
Ex) For certain document: 1. It is reviewed by 2 people (Out of 4) 2. 50% of the sections are filled out. 3. It took 92 days for the document to be approved. With this, we can assign, 50% to X1 since it is 2/4, and 50% to the X2. I'm having trouble assigning 92 days to X3, because they are not ratio (Or percentage).
My idea is to use percentage deviation, 1-(observed-expected)/(expected), so it will be 1-((92-90)/90)=.98, 98%.
However, if you think about possible observed duration of 200 days, this can go well above 100%.
Any suggestions or feedback will be appreciated
