inventory optimisation

In these times of seemingly endless disruption, one powerful strategy for riding the waves is inventory optimization.

To learn more about the why's and how's of this, I invited Robert Olszak from global consulting firm RGP to come on the podcast to talk about it.

We had a fascinating conversation covering the different inventory optimization options, best practices in inventory optimization, and where to from here.

I learned loads, I hope you do too...

How do big grocery retailers maintain product availability for their customers day after day while minimising food wastage and storage costs? The answer is Inventory Optimisation, the science of maintaining sufficient stock levels of a set of products so that customers see an appropriate level of availability when they walk into your store. 

The trade-off
It’s hard because it often costs money to maintain a large inventory of products, because of space that is given over to bulky stock as the cost of buying a large amount of potentially expensive items without getting a return on that investment until sale. A long lead time from stocking to use or sale means no value is extracted from those items and that can have cashflow implications for a company while obviously minimising risk of so-called stockout.

Wastage
A significant further complication comes from food and grocery retail where the items being stocked are themselves perishable with varying expiry dates. Further significant costs are incurred if the product expires while still being stocked. This leads to huge food waste problems around the world which in turn have a significant carbon and environmental impact on the direct supply chain for the retailer.
