Plan Sourcing Strategy
Inputs, tools & techniques, and outputs for this process.
A proactive plan that defines how the project will obtain external products and services, including make-or-buy decisions, sourcing channels, contract approach, supplier selection criteria, risk allocation, and governance.
Purpose & When to Use
- Clarify how the team will acquire needed goods and services from outside the organization to meet scope, schedule, and budget goals.
- Optimize value by choosing the right delivery and contract models that balance cost, speed, flexibility, and risk.
- Align supplier engagement with the project life cycle, whether predictive, iterative, or agile, and set clear performance expectations.
- Use early in planning, revisit at phase gates or major backlog releases, and update when scope, risk, or market conditions change.
- Apply whenever external spend is material, specialized capabilities are needed, or compliance and IP considerations are significant.
Mini Flow (How It’s Done)
- Review context: business case, scope or backlog, schedule, budget, constraints, and enterprise procurement policies and thresholds.
- Assess capability and capacity: perform make-or-buy and outsourcing analysis using total cost of ownership, lead time, and strategic importance.
- Scan the market: conduct market research, identify supplier categories, check competition levels, and develop should-cost ranges.
- Select sourcing approach: single vs multiple suppliers, one-time buy vs framework agreement, waves or bundles, local vs global, and centralized vs decentralized buying.
- Choose delivery and contract models: fixed-price, time-and-materials, or cost-reimbursable, plus incentives, unit pricing, or not-to-exceed as appropriate to requirements stability and risk.
- Define commercial terms and risk allocation: warranties, liabilities, IP and data rights, security, confidentiality, service levels, acceptance criteria, and termination rights.
- Set selection method: prequalification needs, evaluation criteria and weightings, mandatory pass/fail items, independent estimates, and the use of RFI, RFQ, or RFP.
- Plan collaboration and governance: roles and responsibilities, communication cadence, contract change control, performance reviews, and escalation paths.
- Plan logistics and onboarding: lead times, delivery milestones, integration with the team, knowledge transfer, and transition or exit strategy.
- Address compliance and ethics: conflicts of interest, sustainability goals, data residency, and applicable regulations.
- Document and baseline: record the sourcing strategy, update schedule and cost baselines, risks and assumptions, and obtain required approvals.
- Key outputs: sourcing strategy document, supplier evaluation matrix, draft solicitation content, contract model guidance, and updates to plans and registers.
Quality & Acceptance Checklist
- Make-or-buy decision is justified with total cost, lead time, and capability rationale.
- Market research supports feasibility, competition level, and timing assumptions.
- Selected contract type matches requirements stability and risk profile.
- Evaluation criteria and weightings are measurable, unbiased, and agreed by stakeholders.
- Risk allocation, IP and data terms, and warranties are clearly defined and reviewed by legal.
- Service levels, KPIs, and acceptance criteria are specific, verifiable, and tied to payments or incentives.
- Governance model covers roles, decision rights, change control, and performance reporting cadence.
- Lead times, delivery milestones, and supplier onboarding activities are integrated into the schedule.
- Budget includes procurement admin costs, contingencies, and potential incentives or penalties.
- Compliance, ethics, and sustainability requirements are addressed and documented.
- Stakeholder approvals are recorded, and the strategy is baselined with version control.
Common Mistakes & Exam Traps
- Confusing the strategy with execution: strategy defines how you will source; conducting procurement executes the plan and awards contracts.
- Choosing fixed-price when requirements are evolving, which can raise change costs and disputes.
- Ignoring total cost of ownership by focusing only on unit price and not on integration, support, or transition costs.
- Using vague evaluation criteria, leading to subjective scoring and protests.
- Poor risk allocation, such as pushing uncontrollable risks to suppliers, which inflates prices or reduces competition.
- Not involving legal, security, or compliance early, causing late rework and delays.
- Skipping independent estimates, making it hard to spot unbalanced or unrealistic bids.
- Single-sourcing without a continuity plan, creating supply risk for critical items.
- For adaptive delivery, forgetting to plan flexible ordering, backlog-aligned deliverables, and shorter contract cycles.
- Assuming the lowest price is the best value when non-price factors were defined as important.
PMP Example Question
Your project has evolving requirements and a tight timeline. The team lacks a specialized skill and plans to bring in a vendor to work iteratively alongside internal staff. Which sourcing choice best fits the situation?
- Fixed-price contract with detailed upfront specifications and a single delivery at project end.
- Time-and-materials contract with a capped ceiling and sprint-based deliverables.
- Cost-reimbursable contract with award fee tied only to lowest total cost.
- Multi-year exclusive framework with no defined performance metrics.
Correct Answer: B — Time-and-materials contract with a capped ceiling and sprint-based deliverables.
Explanation: Evolving scope and tight timelines favor a flexible model; T&M with a ceiling controls cost while enabling iterative collaboration and incremental outcomes.
