9.2 Procurement Strategy and Supplier Selection

9.2 Procurement Strategy and Supplier Selection

Definition (APM BoK7 glossary): A procurement strategy is the high-level approach for securing the goods and services required from external suppliers to satisfy project, programme and portfolio needs.

This is the wording assessment criterion 6.6 asks for. BoK7 (2.1.4) adds that the procurement strategy is informed by decisions on strategic sourcing and leads to the procurement element of the integrated project management plan, and that it turns on two questions agreed with the sponsor and wider governance: how much risk to retain in the project and how much to share with suppliers, and on a continuum from transactional to collaborative, what type of relationship is desired with different suppliers, and why. BoK7’s governing principle is that "the best outcome is most likely to be achieved if risk is allocated to the party that is best equipped to manage it".

Very few modern organizations possess the complete spectrum of specialized skills, manufacturing plant, raw materials, and capacity required to deliver complex projects entirely in-house. A civil engineering project requires specialized tunneling equipment; an aerospace project depends on proprietary avionics software; a healthcare transformation requires specialized management consultants and enterprise software vendors. Project success is therefore fundamentally bound to how effectively the project team acquires external goods, works, and services from the commercial marketplace.

Procurement is not merely a tactical purchasing activity. Within the APM Body of Knowledge framework, it is a disciplined commercial discipline that begins with defining a high-level Procurement Strategy, conducting rigorous Make-or-Buy analyses, and executing a transparent, ethical Supplier Selection Process.

The Project Procurement Strategy

A procurement strategy is the high-level approach to securing the goods and services the project needs from external suppliers. Rather than ordering items ad hoc, it is formulated during the project’s Definition phase as an integral component of the Project Management Plan (PMP). BoK7 notes that the complexity of the work, the capability of the team, the client or owner’s appetite for risk and the life cycle approach chosen all inform the decisions it records, as does the market analysis in the sourcing strategy.

Core Elements of a Procurement Strategy

• Procurement Packages: Decomposing the WBS into logical contract work packages that can be competitively tendered in the market without creating excessive interface risks.
• Delivery Model: Deciding whether the organization acts as the primary integrator (managing multiple discrete trade contractors) or appoints a single main turnkey contractor (such as an Engineering, Procurement, and Construction [EPC] partner) to manage lower-tier sub-contractors.
• Supplier Selection Route: Determining whether to use open public competition, restricted tendering via pre-qualified frameworks, or direct negotiation (sole-source procurement) under exceptional circumstances.
• Contractual and Reimbursement Model: Selecting appropriate legal contract conditions and payment structures (e.g., fixed price, target cost, cost-reimbursable) aligned with the risk profile of each work package.
• Procurement Timetable: Mapping critical procurement lead times—such as specification drafting, tender periods, evaluation, and supplier manufacturing/mobilization—into the master project schedule.

The Make-or-Buy Decision Framework

Before approaching the external market, the project sponsor and project manager must address a fundamental question: Should the project produce the required deliverable internally using organizational resources, or should it purchase it from external suppliers?

This decision is governed by a holistic evaluation across four key criteria:

+-----------------------------------------------------------------------------------+
|                         THE MAKE-OR-BUY DECISION MATRIX                           |
+-----------------------------------------------------------------------------------+
|  1. Strategic Alignment:    Core Competency & IP Protection vs Non-Core Task      |
|  2. Technical Capability:   Internal Expertise vs Specialized Supplier Technology |
|  3. Financial / Economics:  CapEx & Retained Overhead vs Variable Market Pricing  |
|  4. Capacity & Risk:        Internal Bandwidth Bottlenecks vs Risk Transfer       |
+-----------------------------------------------------------------------------------+

1. Strategic Alignment and Intellectual Property (IP)

• Make: An organization should manufacture internally if the deliverable involves proprietary core competencies, competitive trade secrets, or confidential technology that provides distinct market advantage. Exposing such assets to third parties risks intellectual property leakage.
• Buy: If the deliverable is a standard commodity, non-core activity, or utility (e.g., standard networking infrastructure, office fit-outs, commercial off-the-shelf software), buying from the market is strategically preferable.

2. Technical Capability and Quality

• Make: If the organization already possesses mature internal skills, specialized tooling, and quality systems that meet or exceed market offerings, retaining the work internally ensures direct quality control.
• Buy: When the internal team lacks specialized technical knowledge, certified equipment, or regulatory accreditation, purchasing from established suppliers leverages external expertise, cutting-edge R&D, and proven industry best practice.

3. Financial and Economic Considerations

• Make: Developing an internal solution avoids supplier profit margins and markups. However, it may require substantial upfront Capital Expenditure (CapEx) in plant, facilities, and staff training that cannot be amortized over future business.
• Buy: External suppliers typically benefit from economies of scale by serving multiple clients across the industry, allowing them to deliver at a significantly lower unit cost. Buying transforms fixed internal overhead into variable operational expenditure (OpEx).

4. Operational Capacity and Risk Allocation

• Make: Making in-house is only viable if internal departments have spare capacity and bandwidth. Forcing project deliverables onto an already overstretched operational workforce results in delivery delays and core business disruption.
• Buy: Buying transfers technical, operational, and delivery schedule risk to an external commercial entity contractually bound by service level agreements (SLAs) and financial delay damages.

The Five Stages of the Supplier Selection Process

Once the decision to buy is confirmed, the project team executes a formal, structured supplier selection process. Aligned with APM BoK7 guidelines, this lifecycle progresses through five disciplined stages:

Detailed Breakdown of the Selection Stages

Stage 1: Procurement Planning and Statement of Requirements (SoR)

The foundation of successful procurement is clarity of requirements. The project team drafts a Scope of Work (SOW) or Statement of Requirements (SoR). Requirements may be written as functional/performance specifications (describing what the output must achieve, allowing suppliers to propose innovative solutions) or detailed technical specifications (prescribing exact dimensions, materials, and processes).

Stage 2: Supplier Identification and Pre-Qualification (PQQ)

To prevent wasting time evaluating hundreds of unsuitable bids, the project issues a Pre-Qualification Questionnaire (PQQ) or Selection Questionnaire (SQ). This filters suppliers on baseline organizational fitness:

• Financial Viability: Audited balance sheets, credit ratings, and annual turnover ratios to ensure the vendor will not become insolvent mid-project;
• Track Record and Experience: Case studies and verified client references on similar project scopes;
• Quality and Safety Accreditations: Compliance with international standards such as ISO 9001 (Quality), ISO 14001 (Environmental), and ISO 45001 (Occupational Health & Safety);
• Resource Capacity: Ensuring the vendor has sufficient staff, plant, and management bandwidth to undertake the contract alongside their existing commitments.

Stage 3: Invitation to Tender (ITT) / Request for Proposal (RFP)

The shortlisted bidders are issued a comprehensive Tender Dossier, comprising the Instructions to Tenderers, SoR/SOW, proposed contract terms and conditions, pricing templates, and the evaluation criteria weighting. During the tender window, suppliers may submit Requests for Information (RFIs) to clarify ambiguities. To maintain fairness, all clarification questions and answers must be anonymized and shared simultaneously with all participating bidders.

Stage 4: Tender Evaluation

Proposals are systematically appraised against the published evaluation matrix. Leading procurement governance employs a Two-Envelope Evaluation Method:

• Envelope 1 (Technical & Quality Proposal): Evaluated first by technical experts, blind to price, to score technical competence, proposed methodology, project management controls, key personnel qualifications, risk mitigation, and environmental sustainability.
• Envelope 2 (Commercial & Cost Proposal): Evaluated separately by commercial specialists to calculate whole-life costs, payment milestones, and financial risk.

Scores are combined using a predetermined weighting (e.g., 60% Quality / 40% Price) to determine the Most Economically Advantageous Tender (MEAT), rather than simply accepting the lowest bid, which often leads to poor quality, claims, and disputes.

Stage 5: Negotiation and Contract Award

Before signing, the project manager and commercial lead may conduct final negotiations with the preferred bidder to resolve minor technical ambiguities, confirm key team appointments, and finalize delivery dates. Once formal governance sign-off (e.g., Project Sponsor or Investment Committee approval) is obtained, the contract is signed by authorized signatories. Finally, standard procurement ethics requires offering a constructive debriefing to unsuccessful bidders, explaining where their submissions fell short.

Ethics, Probity, and Fairness in Project Procurement

Because procurement involves transferring substantial financial sums to private commercial entities, project professionals must uphold the highest ethical standards:

• Transparency and Non-Discrimination: All tenderers must be treated identically. Evaluation criteria and weightings must never be altered after tenders have been submitted to favor a particular vendor.
• Conflict of Interest Management: Project personnel must immediately declare any personal, familial, or financial relationships with bidding companies. Anyone with a conflict must recuse themselves from drafting specifications or evaluating bids.
• Anti-Bribery and Corruption: Absolute compliance with statutory legislation (e.g., the UK Bribery Act 2010). Project team members must never solicit or accept gifts, hospitality, inducements, or favors from suppliers.
• Confidentiality: Commercially sensitive information—especially pricing structures and proprietary technical designs submitted by bidders—must be fiercely guarded to maintain competitive integrity.
