Procurement systems operate through contracts and procedures, but people interpret those systems through culture.
Two organisations can sign the same form of contract and behave very differently.
One may raise issues early, share information and solve problems pragmatically. Another may withhold information, escalate defensively and treat every ambiguity as an opportunity to protect its position.
The difference is not necessarily the contract.
The supplied Week 1 notes use Walker and Rowlinson’s systems view of culture, showing national, professional, organisational, project-team and individual cultures alongside deeper layers of observable artefacts, shared values and common assumptions. The procurement slides then connect project culture with transactional, lowest-cost contracting and fragmented teams where relationships may become tense and untrusting.
The model is useful because it reveals something leaders often ignore: procurement behaviour is shaped below the level of policy.
The Strategic Context
Culture influences what people consider normal.
Do teams escalate bad news early? Do buyers believe suppliers are partners, adversaries or interchangeable vendors? Do engineers respect commercial controls? Do procurement professionals understand technical concerns? Do contractors assume variations are a legitimate mechanism or evidence of buyer failure?
These assumptions shape behaviour before formal governance intervenes.
Procurement is especially sensitive because it joins organisations with different incentives and histories for a limited period.
A project team can therefore contain several overlapping cultures at once:
- organisational;
- professional;
- national;
- functional;
- supplier;
- project-specific.
The commercial system has to operate across them.
What Leaders Commonly Misread
Culture is too soft to affect procurement performance
Culture affects communication, trust, escalation and interpretation. Those behaviours directly influence cost, delay and claims.
A strong contract can neutralise culture
Contracts establish rules, but they cannot prescribe every interaction.
A contract can require notification of risk. Culture influences whether people raise that risk early, defensively or only after evidence becomes undeniable.
Supplier culture is fixed
Project-specific culture can be shaped.
Clear governance, joint objectives, leadership behaviour, meeting routines and fair issue resolution can create different norms from those found in either parent organisation.
Collaborative culture means weak commercial control
Collaboration without clarity can be dangerous.
The goal is not to replace accountability with friendliness. It is to create norms where parties can communicate honestly while still respecting obligations and authority.
Reframing the Issue
Culture should be treated as a commercial operating condition.
Leaders do not need to “manage culture” as an abstract concept. They need to understand which behaviours the project requires and whether the procurement model reinforces or undermines them.
If the project depends on innovation and shared problem solving, a highly adversarial commercial model may create friction.
If the work is simple and fully specified, a transactional model may be entirely appropriate.
Culture matters most when behaviour between organisations affects value.
Strategic Analysis
Observable artefacts are only the surface
Policies, templates, meeting structures and procurement systems are visible.
Below them sit shared values: beliefs about fairness, speed, control, customer service or technical excellence.
Deeper still are assumptions that may never be stated: “suppliers cannot be trusted”, “procurement only slows us down”, “the client always changes scope”, or “commercial people do not understand engineering”.
Those assumptions influence decisions even when official policy says otherwise.
Professional cultures can collide
Engineers may prioritise technical robustness. Commercial teams may emphasise contractual exposure. Operations may value continuity. Project managers may prioritise schedule.
None of these perspectives is inherently wrong.
Conflict becomes destructive when one group treats its own definition of success as the only legitimate one.
Procurement choices can reinforce behaviour
Lowest-price competition can be effective for standardised work. Used indiscriminately, it can also select suppliers with little commercial room to absorb uncertainty, increasing sensitivity to change.
Relationship-based approaches can encourage collaboration but may reduce competitive pressure if not governed well.
Commercial architecture sends behavioural signals.
Leadership behaviour becomes the local culture
If executives demand early risk disclosure but punish teams that report bad news, the real culture is concealment.
If buyers insist on fair dealing but exploit every supplier mistake opportunistically, suppliers will adapt.
Culture is learned from consequences.
Culture Becomes Visible Under Commercial Pressure
The most useful time to observe procurement culture is not during mobilisation. It is when something goes wrong.
A supplier misses a milestone. A buyer discovers a scope gap. A technical assumption fails. A variation is larger than expected.
Under those conditions, the project’s real norms become visible.
Do parties disclose information quickly or protect their position first? Do managers search for root causes or for blame? Are commercial notices used as factual governance tools or as threats? Can technical and procurement teams disagree without bypassing each other?
These behaviours determine how quickly the system recovers.
Leaders can deliberately create routines that make constructive behaviour easier. Joint risk reviews, clear escalation thresholds, disciplined issue logs and agreed decision times reduce the need for personal trust to carry the entire relationship. At the same time, fair treatment when problems emerge builds confidence that early disclosure will not automatically be punished.
Culture is therefore not separate from governance. Governance creates repeated experiences, and repeated experiences become expectations.
The strongest commercial cultures combine transparency with accountability: parties can raise difficult information early and still remain responsible for their obligations.
Decision Framework
For major procurements, ask five cultural questions.
- What behaviours does successful delivery require?
- Which existing organisational or professional norms support those behaviours?
- Which assumptions could create friction across the buyer-supplier boundary?
- What commercial mechanisms reinforce the desired behaviour?
- How will leaders respond when parties raise problems early?
This assessment need not become a psychometric exercise.
Its purpose is to expose predictable behavioural risks before they become contractual disputes.
From Strategy to Execution
Immediate action: identify procurement relationships where recurring issues are being labelled “supplier performance” but may actually reflect mismatched expectations, incentives or communication norms.
Medium-term capability: include behavioural expectations in mobilisation. Clarify escalation, decision rights, information sharing and how disagreements will be handled.
Long-term positioning: treat supplier culture and internal procurement culture as part of capability development. Measure whether teams actually behave in ways consistent with stated values.

Signals to Monitor
Watch for defensive meetings, late disclosure of problems, excessive reliance on formal notices for routine coordination, repeated conflict between technical and commercial teams, or suppliers who stop offering improvement ideas because previous suggestions were rejected or exploited.
Also monitor internal language. When teams routinely describe suppliers as “the problem” or procurement as “the blocker”, the organisation may be hiding systemic issues behind functional stereotypes.
Questions for the Leadership Team
- What assumptions do our teams hold about suppliers before work begins?
- Which behaviours does the contract encourage under pressure?
- Where do professional cultures clash across engineering, procurement, finance and project management?
- How do we respond when suppliers disclose risk early?
- Are we creating project-specific norms or merely importing the cultures of parent organisations?
- Which recurring commercial disputes may actually be behavioural-system problems?
Closing Perspective
Culture does not replace procurement strategy, governance or contracts.
It determines how people use them.
Leaders who ignore culture can build a technically sound commercial system that behaves unpredictably because the parties interpret risk, fairness and cooperation differently.
The practical task is to align the commercial model with the behaviours the project requires and to ensure leadership actions reinforce those behaviours when pressure rises.
