Why spend analysis comes first

Procurement's leverage is concentrated, but how concentrated is an empirical question about your own firm, not a rule you can assume. Spend distributions are usually skewed: a minority of suppliers carry a majority of the money, and the shape of that skew determines where sourcing effort pays back. Some firms really do see something close to the classic 80/20 split; others, especially those with a large maintenance and services tail, need half their supplier base to reach 80 percent of spend. Measure it before you plan around it. Without a clear view of where the money goes, the team may spend too much time on purchases with little effect on cost or service. A spend analysis consolidates purchasing data by supplier, category, and item, then asks three questions: How concentrated is spend, how critical is each category to operations, and how much leverage does the firm have over price and supply. The answers drive which categories deserve a category strategy, which deserve a simple online buy, and which deserve to be eliminated entirely. Choose a review schedule that reflects how quickly prices, demand, and the supplier base change.

Kraljic's matrix in practice

Kraljic's matrix segments purchased items by two axes: profit impact (how much a supply failure or price spike would hurt the business) and supply risk (how complex, scarce, or monopolized the supply market is). The four quadrants drive distinct strategies. Strategic items (high profit impact, high supply risk) call for long-term partnerships, joint improvement, and explicit risk management. Leverage items (high profit impact, low supply risk, often commodity inputs at high volume) call for aggressive price negotiation, multi-sourcing, and tight contract terms. Bottleneck items (low profit impact, high supply risk) call for securing supply through long contracts, safety stock, or dual sourcing even at higher unit cost. Non-critical items (low on both) call for process efficiency, e-catalogs, and minimal touch. Misclassifying an item can lead to too little protection for a bottleneck or too much negotiation effort on a routine purchase.

Building the strategy

A category strategy answers four questions: what is the supply market structure, what is the firm's current position, what is the target position, and what are the three to five moves that close the gap. Good strategies include a quantified business case (savings, service improvement, risk reduction), a clear owner, and a time horizon. They also include an explicit decision about what not to do; for example, a decision not to dual-source a commodity input because the savings do not justify the qualification cost. The most useful category strategies are short, two to four pages, and are revisited when the market or the firm's product mix changes materially. A strategy that has not been revisited in three years is not a strategy; it is a habit.

Worked example

Problem

A firm's annual addressable spend is $40,000,000 across 250 suppliers. The top 10 suppliers account for the following annual spend (in $ millions): 5.0, 3.2, 2.8, 2.5, 2.0, 1.8, 1.6, 1.5, 1.4, 1.2. Compute (a) the share of spend with the top 10 suppliers, (b) the share with the top 5 suppliers, and (c) approximately how many suppliers are needed to reach 80 percent of spend if the remaining suppliers are treated as an even tail. Then state whether this spend base fits the classic 80/20 pattern.

Step by step

  1. Top 10 spend = 5.0 + 3.2 + 2.8 + 2.5 + 2.0 + 1.8 + 1.6 + 1.5 + 1.4 + 1.2 = $23.0 million.
  2. Top 10 share = 23.0 / 40.0 = 0.575 = 57.5 percent.
  3. Top 5 share = (5.0 + 3.2 + 2.8 + 2.5 + 2.0) / 40.0 = 15.5 / 40.0 = 0.3875 = 38.75 percent.
  4. Remaining spend after the top 10 = 40.0 - 23.0 = $17.0 million, spread across 250 - 10 = 240 suppliers, so the average tail supplier is 17,000,000 / 240 = $70,833.
  5. The 80 percent threshold is 0.80 x $40.0 million = $32.0 million. After the top 10 we still need $32.0 - $23.0 = $9.0 million.
  6. Tail suppliers required = 9,000,000 / 70,833 = 127.1, so about 127 more, or roughly 137 suppliers in total.
  7. Concentration read: 137 / 250 = 55 percent of the supplier base is needed to reach 80 percent of spend. That is well short of the classic 80/20 shape, which would put 80 percent of spend inside 50 suppliers. This firm has a heavy tail.
  8. Strategic implication of the heavy tail: category strategy work belongs on the top 10 to 25 suppliers, where 57.5 to roughly 70 percent of the money sits, while the 200-plus supplier tail is a process problem (catalogues, P-cards, consolidation) rather than a negotiation problem. Trying to run sourcing events across a 240-supplier tail costs more in procurement labour than it can return.

Answer. Top 10 suppliers account for 57.5 percent of spend; top 5 for 38.75 percent. Roughly 137 suppliers, or 55 percent of the base, are needed to reach 80 percent of spend. This is a flatter distribution than the 80/20 rule of thumb assumes, which changes the plan: negotiate the head, and attack the tail with process automation and supplier consolidation rather than with category strategies.

Practice

Work each question before opening the solution.

  1. A category represents 4 percent of spend but is sole-sourced from a financially distressed supplier and feeds a flagship product. Which Kraljic quadrant does it belong to and what is the dominant risk?

    Show solution for question 1

    High profit impact (flagship product) and high supply risk (sole source, distressed supplier), so it is Strategic. The dominant risk is supply continuity, not price. The strategy should focus on qualifying a second source and on supplier development or transition planning rather than aggressive price negotiation.

  2. Why is classifying a category as Leverage when it is actually Bottleneck a particularly costly mistake?

    Show solution for question 2

    Leverage strategy pushes for aggressive price and multi-sourcing competition, which a tight supply market cannot support. The supplier pushes back, performance deteriorates, and the firm ends up with both a worse price and a worse service level, having burned trust in the relationship that should have been managed as a strategic partnership.

  3. A category strategy says 'consolidate spend with the current supplier to extract 6 percent savings' but does not name a backup source or a contingency plan. What is missing?

    Show solution for question 3

    Risk and exit strategy. Consolidation without a credible alternative removes the firm's leverage the next time something goes wrong, because the supplier knows the firm has no Plan B. A complete strategy would include at least a qualified alternate, a documented transition plan, and a contract clause that protects the firm if performance slips.
