Project Procurement and Contract Management Guide
Integrate make-or-buy decisions, sourcing lead time, contract risk, supplier interfaces, acceptance, and cost commitments.
Core concepts
Build the mental model first
- Make-or-buy analysis
- Comparison of internal and external delivery considering capability, cost, timing, strategy, and risk.
- Fixed-price contract
- Price risk is generally placed more heavily on the seller for defined scope.
- Cost-reimbursable contract
- The buyer carries more cost risk and needs stronger cost oversight.
- Procurement lead time
- Internal approvals, solicitation, evaluation, award, supplier delivery, logistics, inspection, and acceptance.
Formula reference
Calculate—and understand what direction means
| Measure | Formula | Interpretation |
|---|---|---|
| Total procurement lead time | Σ internal + supplier + logistics + acceptance durations | End-to-end time, not only supplier manufacturing. |
| Contract variance | Approved contract baseline − forecast contract cost | Direction depends on the stated convention. |
Worked reasoning
Long-lead equipment package
Situation
The supplier quotes twelve weeks, but the project need date is fifteen weeks away.
Manager’s approach
Add internal approval, evaluation, award, transit, customs, inspection, and acceptance time before judging feasibility; evaluate alternate sources and schedule responses.
Takeaway
A supplier quote is only one component of procurement lead time.
PMP lens
What to remember in scenario questions
- Contract changes follow the contract and formal change process.
- A procurement statement of work should be clear enough for sellers to respond consistently.
- Seller selection uses defined criteria, not price alone.
- Claims administration relies on documented facts and contract terms.
Common doubts
Questions learners ask
Which contract type is always best?
None. Select based on scope clarity, market conditions, risk allocation, incentive needs, and management capability.
Should contingency be hidden in supplier pricing?
Risk treatment should follow the approved commercial and estimating method and remain transparent to authorized decision makers.
Who manages supplier interfaces?
Ownership should be explicit across project, procurement, technical, commercial, and operational stakeholders.
