Strategic Sourcing and Category Management
The Strategic Sourcing and Category Management domain tests segmentation and sourcing decisions: how to analyse spend, group it into categories, understand supply markets, choose a sourcing approach, evaluate offers on total value, and manage supplier relationships by segment.
Core rules and concepts
- Spend analysis. Cleanse and classify spend (UNSPSC, eCl@ss or an internal taxonomy), apply Pareto to find the small share of suppliers carrying most spend, and separate addressable from non-addressable spend. Demand management frequently beats price negotiation.
- Kraljic portfolio matrix. Plot categories by profit impact and supply risk: strategic (partner), leverage (compete), bottleneck (secure and diversify), non-critical (simplify and automate).
- Category strategy is a cross-functional plan: category profile, internal needs, market and competitive analysis (Porter's five forces, capacity, cost drivers, technology), strategy options, implementation plan, tracked benefits.
- Evaluation. Use RFI, RFQ, ITT or RFP according to need. Weight criteria before offers arrive, score against evidence, and award on most economically advantageous tender rather than price alone. Should-cost modelling exposes supplier margins and cost drivers.
- E-auctions suit commoditised, specifiable purchases with credible competition and low switching costs, not complex services.
- SRM. Tier suppliers by importance; strategic suppliers get joint improvement plans, innovation pipelines and executive sponsorship.
Worked example
Two machines meet the specification. A costs £120,000, maintenance 10% of purchase price a year, energy £18,000 a year, and averages five days' downtime annually. B costs £150,000, maintenance 5%, energy £12,000, downtime two days. A day of lost output is worth £2,000. Evaluate over five years.
Reasoning: purchase price alone favours A. Total cost of ownership: A = 120,000 + (5 × 12,000) + (5 × 18,000) + (25 downtime days × £2,000) = £310,000. B = 150,000 + (5 × 7,500) + (5 × 12,000) + (10 × £2,000) = £267,500. B is cheaper by £42,500 despite the higher price, and the downtime difference should be probed in reference checks. Add qualitative factors such as spares lead time and energy price trend before awarding.
Traps that cost marks
Awarding on purchase price; setting weights after seeing bids; using an e-auction for a complex service; misplacing categories on Kraljic (bottleneck is about supply risk, not spend); failing to validate spend data.
