PMGT5820 Chap.4 Resources, Procurement and Supplier Decisions
Resources, Procurement and Supplier Decisions
Resource and procurement management connect capability, timing, sourcing, supplier evidence and contract risk. This chapter moves from a defined need through make-or-buy and market-route choices to weighted evaluation, negotiation, award and supplier control. It stresses that a numeric ranking supports a decision only when mandatory conditions, evidence quality and sensitivity are also visible.
A sourcing route should follow the nature of the need rather than habit. Stable commodity requirements permit a different comparison from an uncertain service whose value depends on method, integration and learning. Evaluation criteria must distinguish meaningful strengths, avoid double-counting and state the evidence that earns each score before proposals are opened.
Contract form then allocates selected risks but cannot erase project exposure to delay, poor quality, claims or supplier failure. Award begins a managed relationship. Promised capability must become owned deliverables, milestones, review evidence, invoices, change routes, acceptance conditions and closure obligations connected to the wider project control system.

Key terms
- Mandatory condition
- A requirement a proposal must meet before it can remain in the comparative evaluation.
- Weighted score
- The sum of criterion scores multiplied by their stated decision weights.
- Sensitivity check
- A test of whether plausible changes in assumptions, scores or weights alter the preferred option.
- Procurement register
- A current record of sourcing actions, commitments, performance, changes and closure obligations.
Resources, Procurement and Supplier Decisions FAQ
How should supplier criteria be chosen?
Start from the required outcome, interface, timing, quality evidence and constraints. Use criteria that separate meaningful supplier strengths without double-counting. Define the evidence and scale before proposals arrive, and screen mandatory requirements before calculating a weighted ranking.
Does a fixed-price contract remove project risk?
No. It can allocate some cost risk when scope is well defined, but uncertainty may return as exclusions, disputes, change requests, quality shortcuts or supplier failure. Schedule, operational and reputational consequences may remain with the project.
What happens after a supplier is selected?
Convert proposal commitments into contract deliverables, milestones, owners, review points and acceptance evidence. Track invoices, risks, changes, performance and outstanding obligations. Award begins supplier control; it does not complete procurement management.
Assessment move
Build one supplier table from a fresh scenario and explain every criterion before calculating. Re-score after a plausible weight change and describe what the sensitivity means. Then trace the selected supplier into schedule milestones, risk ownership, acceptance evidence and procurement closure so the commercial choice remains connected to project control.
Begin by writing the outcome, interfaces, timing, quality evidence and constraints without naming a preferred supplier. Decide whether internal delivery is feasible and identify the uncertainty that the market route must handle. Separate mandatory conditions from scored criteria. For each criterion, define a scale and the proposal evidence that supports a high, medium or low score.
Check that two headings are not rewarding the same experience or capability. Perform the weighted calculation, show every contribution and compare the margin between alternatives. Change one plausible weight or score to test whether the ranking is robust. If a small change reverses the result, report that sensitivity as decision information rather than concealing it behind a decimal total.
Add qualitative checks for concentration, conflict, capacity and unsupported claims. Once a supplier is selected, convert its proposal into a control map containing contract deliverables, dates, owners, linked schedule activities, risk triggers, review points and acceptance evidence. Rehearse a post-award dispute by tracing the statement of work, assumptions and authority before recommending enforcement or change.
Close revision by listing the commercial records needed for final acceptance, payment, warranty, claim resolution and future supplier learning. Check that every promised benefit has a matching contract obligation or management action rather than relying on proposal language after award.
