Index vs Target Reference Table


Indexes are used in order to compare with target setCalculations
Process Effectiveness

YTD only
Using ponderation as 75% for payment on time and late posting as 25%.
YTD Average based on monthly index
Exemple for Jan 2019 to Sep 2019: 1.81
Index for Sep 2019 : 2.25
Payment on Time (Volume) Sep 2019 : 90%

Late Posting Sep 2019 : 4.7%
We can see that :
90% Payment on Time will fall under the score of 2
4.7% late posting will have score of 3
With that, the result will be (2 x 75%) + (3 x 25%) = 1.5 + 0.75 = 2.25
Process Conformity

YTD only
Using ponderation as 40% for buying channel, 30% invoicing (3 ways match), 15% late invoices and 15% non conform PReq.
YTD Average based on monthly index
Exemple for Jan 2019 to Sep 2019: 3.58
Index for Sep 2019 : 3.85
Buying Channel - 66%

Invoicing (3 ways match) - 65%

Late invoices - 13%
Non conform PReq - 2.7%
We can see that :
66% Buying Channel falls under the score of 4
64.5% Invoicing (3 ways match) have score of 4
13% Late invoices have score of 2
2.7% Non conform PReq have score of 5
With that, the result will be (4 x 40%) + (4 x 30%) + (2 x 15%) + (5 x 15%) = 1.6 + 1.2 + 0.3 + 0.75 = 3.85
Process Productivity

YTD only
Using ponderation as 60% for invoice per FTE and 40% PO per FTE.
YTD Average based on monthly index
Exemple for Jan 2019 to Sep 2019: 2.91
Index for Sep 2019 : 2.6
Invoice/FTE - 884
PO/FTE - 332
We can see that
  • number of invoice/FTE 884 falls under the score of 3
Figures for 1 month :


  • number of PO/FTE 332 has score of 2
Figures for 1 month :


With that, the result will be (3 x 60%) + (2 x 40%) =1.8 + 0.8 =2.6
