The SCOR Model

Supply Chain Council, now ASCM · 1996

Also known as Supply Chain Operations Reference model

A shared vocabulary and set of measures for the standard processes every supply chain performs.

Its place in the frameworkBusiness Core›Supply Chain

What it does

It names the chain’s activities — plan, source, make, deliver, return, enable — at increasing levels of detail and attaches standard metrics to each. Its worth is comparability: without a shared definition, two companies measuring the same thing are measuring different things, and neither knows it.

Reach for it when: When comparing performance against anyone outside the company, or when two organisations have to describe a shared chain to each other.
Where it stops: It standardises description, not design. A chain can score well on every standard measure and still be the wrong chain for the strategy.

Supply Chain Operations Reference model, Supply Chain Council, from 1996; now maintained by ASCM.

Why it sits at Supply Chain

Everything between a supplier and a customer — sourcing, moving, holding and delivering. The part of the business most exposed to events nobody controls.

A model is only useful when you reach for it at the right moment. This one answers a question that arises here — so it is filed here, and nowhere else. These are the working areas it serves:

SourcingProcurement practice and the Kraljic matrix, which sorts purchases by profit impact and supply risk to decide how each should be handled.
LogisticsLogistics management on the cost-speed-reliability trade-off, and total landed cost rather than freight price alone.
InventoryInventory theory: safety stock, reorder points and the service-level trade-off; and lean’s treatment of inventory as a symptom of variability elsewhere.
ResilienceSupply chain risk management, and the post-2020 literature on the efficiency-resilience trade-off that most organisations had resolved without noticing.

All of Supply Chain

What it touches elsewhere

Nothing in a business is decided on its own. A conclusion reached with this model at Supply Chain lands in these other cores, whether or not anyone follows it there.

Business CoreSuppliers are partners, and the terms sit in the same place as any other agreement.
Time CoreLead times and contingency planning are the same conversation from two directions.
Omni CoreDelivery is often the most tangible part of what a customer experiences.
Data CoreService level, lead time variability and stock turn are what tell you the chain is healthy.

Filed at the same place

These answer questions that arise at Supply Chain too. Where they disagree with this one, the disagreement is the useful part.

The Kraljic MatrixSort what you buy by how much it matters and how risky it is to get, and buy each kind differently.
The bullwhip effectSmall changes in end demand grow into large swings the further back up the chain you go.
On-time in-fullOne measure of delivery that counts an order as good only if it arrived complete and on the day promised.

Elsewhere in Business Core

These are other people’s models, named here so you can go to the source and use them properly. The Omnigoal is not affiliated with their authors and is not endorsed by them; nothing of theirs is reproduced here — no canvas, no diagram, no wording. Each is described in our own words, with the originator credited, because the framework is a place to put thinking, not a replacement for the people who did it. Model names and trademarks belong to their respective owners and are used here only to refer to the work itself.
