7 Procurement and Supplier Management

Plan the purchase

Procurement is the process of obtaining goods or services from outside an organization. Effective procurement connects project needs with a suitable delivery approach, supplier, contract, and monitoring plan. It begins during planning and continues through contract closeout.

Start by defining the need in terms of outcomes, required quality, quantities, delivery dates, constraints, and acceptance criteria. Research the market to understand what suppliers can provide, typical lead times and prices, and whether viable alternatives exist. Use these findings to shape the requirements and procurement schedule.

A procurement plan should identify:

• What will be purchased and when.

• Whether work will be made internally, bought, or delivered through a combination of approaches.

• How suppliers will be invited and evaluated.

• Who approves decisions and manages the contract.

• The budget, schedule milestones, acceptance checks, and key risks.

Allow time for the full procurement process, not just delivery. For example, a purchase of specialized testing equipment may require supplier research, a competitive request, technical evaluation, delivery, installation, and acceptance testing, in addition to shipping time.

Compare delivery options

A make-or-buy analysis compares internal delivery with external purchase. A mixed approach may also be appropriate, such as building a core system internally while purchasing a specialist component.

Compare options using whole-life cost rather than only the initial price. Consider setup, staffing, training, operating, maintenance, integration, transition, and end-of-life costs, alongside schedule and performance risks.

Assess whether the organization has the skills, capacity, time, and facilities to deliver internally, and whether the work is strategically important or involves sensitive knowledge. Also consider whether suppliers offer better expertise, technology, scale, or speed. Supplier dependence, integration effort, and the ability to support the result after delivery are relevant as well.

For example, an internal team might develop a reporting tool for $\$60{,}000$, with $\$20{,}000$ in support costs over two years. A supplier might offer a tool for $\$50{,}000$, with integration and two years of subscriptions adding $\$35{,}000$. The estimated whole-life costs are $\$80{,}000$ for the internal option and $\$85{,}000$ for the supplier option. Faster delivery or stronger support could still justify the higher supplier cost. Record assumptions and compare benefits and risks alongside cost.

Evaluate suppliers consistently

Use market research to identify potential suppliers, then set evaluation criteria that reflect project priorities. Criteria may include technical fit, quality, delivery plan, relevant experience, team capability, support, financial or operational resilience, and total cost.

State the criteria and their relative importance before reviewing bids. Assess each supplier against the same criteria and document the reasons for the decision. A best-value choice balances price with quality and delivery capability rather than automatically selecting the lowest bid.

A weighted scorecard can make comparisons transparent. One example assigns technical fit a weight of $40\%$ and a supplier score of $4$ out of $5$; delivery confidence a weight of $25\%$ and a score of $5$; relevant experience a weight of $15\%$ and a score of $3$; and whole-life cost a weight of $20\%$ and a score of $4$. Multiply each score by its weight and add the results. Scores support judgment, but do not replace checking minimum requirements, validating references, or considering significant risks.

Set up and manage the contract

The contract turns the selected proposal into clear, enforceable commitments. Define the scope, deliverables, schedule, price and payment basis, acceptance process, quality requirements, responsibilities, reporting, change control, confidentiality or data obligations, remedies, and exit or transition arrangements.

Fit the pricing approach and allocation of risk to the work. A fixed price can suit a well-defined scope, while uncertain or changing work may need a different arrangement and stronger cost controls. Assign risks to the party best able to manage them, and avoid transferring risks a supplier cannot reasonably control.

After award, manage the supplier actively. Hold a kickoff and regular review meetings, track milestones, cost, quality, issues, and risks, and inspect or test deliverables against acceptance criteria. Record decisions and changes, and use agreed escalation routes to address problems early.

Manage procurement risks and performance

Common procurement risks include supplier failure, long lead times, poor quality, price increases, unclear requirements, weak subcontractor performance, cybersecurity or data exposure, and dependence on a single source.

For each important risk, identify its likelihood and impact, an owner, warning signs, a response, and any contingency. Responses may include qualifying an alternate supplier, ordering long-lead items early, staged acceptance testing, backup capacity, or transition assistance. Market research and continuing supplier monitoring can help identify risks before they threaten delivery.

Track procurement performance with measures tied to the contract, such as on-time delivery, defect rate, acceptance-test pass rate, response time, cost variance, or unresolved critical issues. Define how each measure is calculated, its target, and what action follows if performance falls short.

Close out procurement

At closeout, confirm acceptance, resolve outstanding claims or actions, complete the handover, and capture performance and lessons learned. Contract administration includes monitoring progress and compliance with the contract throughout its performance.

To apply these practices to a project deliverable, compare make, buy, and mixed options using whole-life cost. Draft three supplier evaluation criteria, one acceptance test, and two procurement risks with responses.
