Optimize system velocity using the
Flow Index Report

The Demand Driven Operating Model comes with a set of operational metrics, one of which is the Velocity. This metric refers to the speed at which materials and products move through the supply chain, facilitated by strategically placed inventory buffers.

The Flow Index Report

This report helps to measure velocity at the decoupling points, by comparing the order frequency across multiple products. In the screenshot below you can see, in the horizontal axis, the order frequency in number of days, and in the vertical axis, the number of stock buffers that fall into each order frequency. Clicking on each of the bars will take you to the stock buffers falling in that category.


Understand the results

Rarely ordered

Products that fall into the high number of days of reordering frequency indicate that are rarely ordered. This may be due to a decreased popularity of the product, the use of too large minimum order quantities when reordering, reordering too infrequently, or a combination of those.

This translates into excess inventory that is not being used to protect the flow, and is becoming a liability to the organization, often ending up in inventory write-offs.

Those cases need to be analysed in detail. In some cases it may be beneficial to reduce the minimum order quantities or to increase the reorder cycle.

Too frequently ordered

Each time we reorder a product we incur in transactional costs associated with the actual purchase. Those costs can be administrative, excessive coordination efforts, transportation, inspections or quality assurance. 

While reordering frequently has many benefits, such as reduced storage and reduced risk, it has to be weighted against the transactional costs.

Increasing the minimum order quantities or the reordering review cycle could be beneficial in those cases where the transactional costs outweigh the benefits of improved velocity.
