In brief
Demand pooling combines similar requirements from several sites, departments or periods in order to improve terms and processes.

What is Demand pooling?
With demand pooling, individual requirements that would otherwise be ordered separately are combined into larger volumes. This strengthens the negotiating position with suppliers and reduces the number of ordering and invoicing transactions. It is a key instrument of strategic procurement and often the basis for framework agreements.
Pooling can take place across sites, for example when several plants need the same item; across categories, when one supplier covers several related ranges; and over time, when a year's requirements are combined in one contract. A prerequisite is transparency about actual consumption and uniform item descriptions. Pooling therefore often goes hand in hand with standardisation: variants of the same part are reduced so that larger quantities arise in the first place.
Limits become apparent with critical and equipment-specific parts. Here, availability, originality and traceability count for more than price, and pooling with only one supplier can increase the risk of supply failure. It therefore makes sense to differentiate by criticality: standard and wear parts are pooled, while critical parts remain deliberately secured.
In practice: maintenance and procurement
A first step is to reconcile the material masters of several sites: the same part is often held under different numbers. Using the manufacturer part number, such duplicates can be identified and then included in a joint enquiry.

Frequently asked questions
What types of demand pooling are there?
A distinction is usually made between geographical pooling across several sites, pooling by subject across categories or items, and pooling over time, in which the requirements of a longer period are combined in one contract. In practice, these forms are combined, for example in a cross-site annual contract for one category.
What is the difference between demand pooling and supplier consolidation?
Demand pooling starts with the requirement: similar quantities are combined. Supplier consolidation starts with the supplier base and reduces the number of sources of supply. The two are closely linked, as pooled requirements are usually placed with fewer suppliers, but one is possible without the other.
What does demand pooling require?
Reliable consumption data, unambiguous item master data and specifications that are as standardised as possible are needed. If identical parts are named differently at different sites, the pooling potential remains hidden. Internal coordination is also needed so that sites and specialist departments actually use the joint contracts.
When does demand pooling not make sense?
For critical, equipment-specific or rarely needed parts, pooling can bring more risk than benefit, for example if only one supplier remains as a result. Even where standardisation would force technical compromises or quantities remain small despite pooling, the effort often outweighs the advantage.
