DIFOT


DIFOT or OTIF is a measurement of logistics or delivery performance within a supply chain. Usually expressed as a percentage, it measures whether the supply chain was able to deliver:
OTIF measures how often the customer gets what they want at the time they want it. Some consider it superior to other delivery performance indicators, such as shipped-on-time and on-time performance, because it looks at deliveries from the point of view of the customer.
This key performance indicator has the advantage of measuring the performance of the whole logistic organization in meeting customer service expectations. To reach a high OTIF level, all the functions of the supply chain must work at their best level.

Calculation

Generally OTIF is calculated by taking into account the number of deliveries:
OTIF = number of deliveries OTIF ÷ total number of deliveries * 100
But it can also, according to organizations, be calculated according to the number of orders or the number of the order lines.
Some organizations calculate OTIF by the percentage of the total order quantity that has been on-time. This goes against the principle of OTIF as the in-full component of OTIF has not been met.
Requirements for the OTIF measurement are :
If the orders are split at the customer request, then each delivery line is considered.
Companies which have set up a measure of the OTIF are unanimous in recognising its value. They quote among other positive aspects: the increase of the operating profit due to the reduction of operating expenses and the increase of sales.
Typically, leading practice in the retail sector would demand an OTIF in excess of 97 per cent measured at a stock keeping unit level.
The OTIF notion was extended to DIFOTAI, which also takes into account the quality of the invoicing.
