Hi Experts:
I have a problem regarding scores when it comes to KPIs that have negative targets and negative actuales eg. Actual= - 1 Target= - 1 Score= -100% (red status of course, since I have tolerance set red for scores below 89). But actually if I planned -1 and achived -1 my score should be 100% (light green satus) and not -100.. and if by the same target (-1) I achieve 0, 1,2 + my score should be even better (over 100).
At the moment the formula I'm using in PAS is the classical Achievement formula to calculate scores, could anybody advice any alternative formula for these cases?
Thank you in advance
