“Plan Sourcing Strategy” (often called Procurement Planning) focuses on how the project will acquire products, services, or results from outside the organization to maximize valuue. Plan Sourcing Strategy is the process of determining what to procure, how to procure it, from whom, and under what terms, aligned with organizational strategy and project objectives.
Key Objective
Ensure the right resources are obtained at the right time, cost, quality, and risk level
Core Decisions in Sourcing Strategy
1. Make-or-Buy Analysis
Decide whether to:
Make internally
Buy from external vendors
Example:
Develop solar panels internally
Procure from specialized vendor
2. Sourcing Approach
Single supplier vs multiple suppliers
Local vs global sourcing
Strategic partnership vs transactional vendor
3. Contract Type Selection
Fixed Price (FP)
When scope clarity is very high and uncertainty is low
In all fixed price contracts, the Cost risk is with the Seller where as all other risks like Schedule, Quality etc is high on the Buyer.
Cost Reimbursible (CR)
Used when there is high uncertainty
In all cost reimbursible contracts, the cost risk is high on the buyer. The seller will never make a loss.
Time & Material (T&M)
Used when Scope is higly flexible
The cost risk is high on the buyer
Purchase Order
Used to procure off the shelf, standard items

How vendors will be selected
Evaluation criteria (technical, cost, experience)
Approval workflows
5. Risk Allocation
