Procurement and Supply Principles

This domain tests whether you understand why procurement exists and the principles that govern sourcing decisions. Expect questions on the procurement cycle, the five rights, value versus price, ethical and sustainable sourcing, and the difference between a transactional purchase and a strategic sourcing decision.

Core rules and concepts

  • The CIPS procurement cycle is a continuous loop: understand need, define specification, develop strategy, identify suppliers, evaluate, negotiate, contract, implement, manage performance, and review. Stages overlap; a review can restart the cycle.
  • The five rights are right quality, quantity, time, price and place/source. They trade off: faster delivery may raise price; tighter quality may reduce supply options.
  • Total cost of ownership (TCO) includes acquisition, use, maintenance, disposal and risk costs. Price is only the entry ticket.
  • Ethical sourcing means applying the CIPS Code of Conduct: integrity, transparency, fairness, respect and professionalism. Sustainability adds environmental and social criteria (for example ISO 20400 guidance).
  • Spend analysis by category, supplier and risk directs effort: high-spend, high-risk items need strategic sourcing; low-spend, low-risk items suit catalogue or spot buying.

Worked example

A buyer compares two printers. Printer A costs £400 and uses £120 of toner a year for four years; disposal is £20. Printer B costs £550 and uses £70 a year; disposal is £20. TCO A = 400 + (120 × 4) + 20 = £900. TCO B = 550 + (70 × 4) + 20 = £850. B is £150 dearer to buy but £50 cheaper over life. Reasoning: compare like-for-like periods and include recurring costs; if annual volumes differ, adjust per page. The principle is to evaluate the cost of the whole requirement, not the invoice.

Traps that cost marks

  • Choosing the lowest purchase price and ignoring TCO.
  • Treating the five rights as independent; exam scenarios usually involve a trade-off.
  • Describing the procurement cycle as a one-way linear process.
  • Reducing ethics to a policy document rather than behaviours and supplier due diligence.
  • Assuming strategic sourcing is always appropriate; low-risk buys can be handled transactionally.
