Delivery performance (DP) is a broadly used standard KPI measurement in supply chains to measure the fulfillment of a customer's demand to the wish date. Following the nomenclature of the DR-DP-Matrix three main approaches to measure DP can be distinguished:
Type of measurement: volume (V)/singular(S) Type of view: on time (T)/ delivery (D)
Volume/on time
Formula If ()
Else NULL
Demand:= customers wish c:= product identifier p:= Time period e.g. a day, a week, a month ...
The cumulation over a period and a group of product identifiers c is done as follows:
whereas p is determined by demand period
Singular/delivery and singular/on time
Singular case definition To fit to the needs of the environment, the granularity of a singular case () has to be defined. In general a singular case is described by a n-Tuple consisting of a set of the following order and delivery details: order number customer identifier product identifier wish date of customer confirmed date of supplier ship to information delivery date delivery note number
Formula
After a singular case has been delivered to the customer its DP is measured as follows: If (wish date = arrival date) then DPsingular case=1 else DPsingular case=0
arrival date = delivery date + transit time
By cumulating the results of singular cases over a certain period p and, if necessary, additional criteria c (e.g. customer, product, ...) the delivery performance is calculated as follows:
whereas p is determined by the arrival date
After a period has elapsed all singular cases with wish date within period are considered and their DP is measured as follows: If (wish date = arrival date) then DRsingular case=1 else DRsingular case=0
arrival date = delivery date + transit time
By cumulating the results of singular cases over a certain period p and, if necessary, additional criteria c (e.g. customer, product, ...) the delivery performance is calculated as follows:
whereas p is determined by the first confirmed date
