Category management in procurement: a practical UK guide

What category management actually is

The case for doing this properly is not theoretical: category management strategies deliver around 12% average savings across indirect spend (Gitnux) ^[1], and category-based strategic sourcing more broadly produces savings in the 5-20% range (US Government Accountability Office) ^[3]. Category management groups related spend - IT hardware, logistics, professional services, MRO, packaging - so that one team can build market knowledge, run coordinated sourcing and manage suppliers to a strategy. It is the difference between negotiating one contract at a time and shaping a category over three years.

The five-step category cycle

• Understand - spend, demand, specifications, incumbents, contracts and internal stakeholders.
• Analyse the market - suppliers, capacity, cost drivers, benchmarks, disruptors and regulation.
• Set the strategy - a one-page category strategy with sourcing approach, targets and risks.
• Execute - sourcing waves, negotiation, transition and contract mobilisation.
• Manage - performance, compliance, savings tracking and continuous improvement.

Segmentation before strategy

The Kraljic matrix is old but still useful for one purpose: forcing a category owner to separate categories where price is the point (leverage, routine) from categories where risk and value dominate (strategic, bottleneck). Sourcing approach should differ - a leverage category runs a reverse auction; a strategic category runs a joint value plan.

Tail spend is where category discipline pays off fastest

Tail-spend optimisation and category programmes yield 15-20% savings for a majority of organisations (Worldmetrics) ^[2], and it is usually the fastest category to show results because it has had the least attention. Bringing fragmented, low-value suppliers under a single category owner is often the first sourcing wave worth running.

Category strategy on a page

The best category strategies fit on one page and answer seven questions:

• What do we spend, with whom, on what, and why?
• What is happening in the supply market that could help or hurt us?
• What is our target - price, cost, service, risk, ESG - over the next three years?
• What sourcing approach fits (auction, RFP, joint plan, single-source renegotiation)?
• What do we need internally - demand consented, specs frozen, stakeholders aligned?
• What are the go / no-go decisions and who owns them?
• How will we measure savings, value and risk over time?

Category-team sizing benchmarks

A common failure mode is asking two people to run £150m of category spend across four disparate towers. See our target operating model guide for team sizing benchmarks by spend band and category mix.

Where category management goes wrong

• No demand control - buyers negotiate a great price on a spec no one questioned.
• Solo sourcing waves - each event optimised in isolation, no category compounding.
• Category owners with no time - firefighting P2P instead of shaping strategy.
• No savings governance - reported savings never reach the P&L.
