Case Studies
Real-world examples of flexible procurement — from airlines to IT implementations. Each calculator scenario is based on a documented case.
Ryanair Fleet Procurement
Ryanair bulk-ordered Boeing 737s during crises (post-9/11: 100 aircraft), achieving below-market prices through negotiation flexibility — without rigid tender procedures.

Rura vs Pole — ten sam zakup, dwa światy
An EU-threshold public tender is a pipe: one locked path, buyer as step-executor. A procurement policy is a field: authorisation boundaries active everywhere, buyer as value navigator. Same contract — drastically higher opportunity cost on the pipe side.

Coupa Catalog — Amazon-like UX for B2B
Companies with end-to-end catalogs reduce maverick spend by 60–80% and cut order time from days to minutes. The buyer becomes a catalog curator, not an invoice processor.

Zara MRP — 2-tygodniowy cykl kolekcji
Zara implemented MRP-driven procurement for raw materials — AI forecasts demand, system generates orders. Traditional tender procedures were too slow for the 2-week production cycle.

Ryanair CAPEX — Boeing bulk order at crisis prices
Ryanair applies full CAPEX governance for fleet purchases — but cuts it 30% via Boeing pre-qualification as sole supplier. Governance has value; waste lies in steps that can be eliminated.
Rigid procedure
60 days
CAPEX investment (justified governance)
Procurement policy

Why don't airlines use open tenders?
Fleet procurement (e.g. LOT — 40 Airbus A220, Ryanair — 100× Boeing 737 post-9/11) is conducted through direct manufacturer negotiations, often exploiting market crises to achieve below-catalogue pricing. No public tender could match that level of timing and negotiation flexibility. Result: Ryanair built a 400+ aircraft fleet with margins competitors can only envy.

The Enforcement Fallacy
A common counter-argument: “if users bypass the process, the process isn't enforced well enough — just block the bypass.” This misunderstands the dynamics. Lipsky (1980) showed that frontline workers alwaysadapt rules to operational reality. Vaughan (1996) demonstrated that forced compliance without operational slack creates “normalization of deviance” — invisible workarounds that accumulate until catastrophic failure. Holmström & Milgrom (1991) proved that enforcing compliance on measurable steps crowds out value creation on unmeasured ones. Enforcement does not fix the incentive structure — it hides the problem.
