| Oct 3, 2019 at 20:47 | comment | added | Reza Afzalan | My question is about $realization$ please update the answers and include it, so I can select it as right answer, also if possible add some reference material. | |
| Oct 3, 2019 at 20:40 | comment | added | prubin♦ | You could use $\frac{a-g}{\max\{a,\epsilon\}}$ for some arbitrary $\epsilon >0$ (maybe $\epsilon = 1$). If $g=0$ and $a$ gets close to 0, it will depart from the previous formula. I've seen variations of this in other contexts. | |
| Oct 3, 2019 at 18:45 | comment | added | Reza Afzalan | OK, if we use $(a-g) /a$ to calculate deviation then with $1-deviation=realization$ will get $realization=g/a$ that is the same formula we are using already. | |
| Oct 3, 2019 at 18:11 | comment | added | prubin♦ | Your question said "lower is better" and mentioned goal zero. If lower is better and outcomes cannot be negative, actual = 0 would imply goal = 0. As I said in the answer, we would just define this as 100% (which is the limit of the formula I gave as $a\rightarrow g$ when $g=0$. There is one catch: using my formula, any $a$ results in 100% when $g=0$. So the problem is not $a=0$, but you may not be happy with the formula when $g=0$. | |

| Oct 2, 2019 at 22:25 | comment | added | Reza Afzalan | I think when kpi meets the target, we have to get 100% for the realization ratio and 0 deviation, and your answer is closer to the deviation than the realization ratio. | |
