When to use it
- The team needs options beyond incumbents and referrals.
- A category has multiple possible supplier segments.
- Sourcing needs a clean handoff into shortlist planning.
Supplier discovery
Supplier Discovery Playbook
Supplier discovery should capture why a supplier might fit, what evidence supports that view, what constraints are known, and what questions remain.
Version 1.1. Last reviewed July 11, 2026.
Overview
Create a structured supplier universe before shortlist planning or formal evaluation.
Supplier discovery should capture why a supplier might fit, what evidence supports that view, what constraints are known, and what questions remain.
Example artifact
How this playbook shows up in the sourcing packet.
This playbook produces a reviewable artifact that connects to the starter-kit workflow. It should capture source notes, assumptions, owners, status, open questions, and the decision gate for the next sourcing stage.
When it is not sufficient
It does not decide the supplier shortlist, evaluate proposals, score vendors, or approve final suppliers. It prepares evidence for human review.
Decisions supported
- Which suppliers deserve additional research.
- Which candidates appear to match the sourcing model.
- Which evidence gaps need validation before outreach.
Inputs required
- Market scan findings
- Supplier websites
- Directories and referrals
- Incumbent information
- Geographic or capability constraints
Included artifacts
- Supplier discovery grid
- Source URL and note log
- Fit-signal fields
- Evidence gap tracker
- Priority indicator
Example prompts and questions
- What capability signal supports inclusion?
- What constraint could disqualify this supplier?
- Which claims are unverified?
- Does the supplier fit the sourcing model or only part of it?
Illustrative use case
Illustrative example: a sourcing analyst records regional facilities providers, local trade firms, a national IFM provider, a specialty HVAC network, and the incumbent. Each has fit signals, constraints, evidence gaps, and a priority status.
Common mistakes
- Shortlisting based on familiarity.
- Mixing verified facts with unsupported claims.
- Leaving source notes blank.
- Ignoring coverage or capacity limits.
Frequently asked questions
How many suppliers should discovery include?
Enough to understand viable options and market variety; the right number depends on the category.
Can an incumbent be included?
Yes, but incumbent familiarity should be documented separately from evidence of future fit.
