Scorecard Question Part 1 - multiple IFs formula - excel-formula

Question

my challenge is of 2 parts (2nd part was already responded by Michal Rosa and Lee Mac).
Here is part 1:
I am working on a scorecard which has series of references. I initially wrote a series of Nested IFs which was very long and also is tedious to change especially when targets change. How can I hardcode or create a formula where I can just change the targets/scoring matrix on the table
Please see sample data:
KRA Data
Say if the agent's LOB is Email, and is in a tenure of 61-90 Days, we return corresponding KRA Rating from the KRA Rating Matrix depending on Actual Score. Like for Agent 1, her Actual Closure score is 18.55 and corresponding KRA rating for her tenure of 61-90 Days is 4.
Similarly, for her TPH, her Actual TPH is 7.02, which assigns a KRA Rating of 3 in the Scorecard Rating Matrix.

Answer 1

You can use nested INDEX / MATCH :
For the outer one (i.e. the one that will find the rating), you use a MATCH which will match the nearest value in the table that is still less than value. You have to modify the look of your rating matrix, instead of putting 4.5 - 5.5, you have to put a single value, i.e. 4.5. You always start with the lowest possible value (typical 0 or minus something), and you end with the highest value.
With the inner one, you extract the array (row) from your matrix that matches both criteria (tenure and LOB), and this array will be fed into the outer match. As it is now, you have to use two formula's, one for the TPH and one for the closure. If your KPI would not be in merged cells, but on each row (like for Tenure and LOB), you could add another condition in the inner MATCH and do everything with a single formula.
The array formula (ctrl+shift+enter) is like this:
{=INDEX($C$1:$F$1;MATCH(D9;INDEX($C$2:$F$5;MATCH(1;($A$2:$A$5=$A9)*($B$2:$B$5=B9);0););1))}
This is a screenshot, starting from A1 (Tenure) and with the formula in F9. I used the colors of your spreadsheet to make it more visual.
This is the same formula with the cell and range references replaces by text so you can better understand and replace with the correct ranges of your worksheet. I hope it is self-explanatory, otherwise just ask:
=INDEX(The_rating;
MATCH(closure-rate_value;
INDEX(Matrix_with_closure-rate_cutoffs;MATCH(1;(LOB_column=LOB_value)*(Tenure_column=Tenure_value);0););1))
