The outline
What's inside the guide
Nine pages of actionable frameworks, templates, and governance principles. Writte for teams who need to move beyond spreadsheets and secondary data without rebuilding their process from scratch.
Assign an internal advocate
How to identify the one person whose ownership determines whether your supplier programme succeeds or stalls, and what they need to run it effectively.
Scope before you request
A data readiness framework for mapping what you already hold internally before contacting a single supplier, so you only ask for what you actually need.
Start with a Minimum Viable Data Request
A staged approach to supplier engagement that builds model confidence early, then targets quality improvements only where hotspot analysis makes them worthwhile.
Define governance upfront
Clear rules for submission, approval, traceability, and confidentiality that make supplier data defensible and scalable rather than ad hoc.
Validate without creating friction
A simple quality ladder, 30-second review checks, and acceptable evidence types that keep validation consistent without overburdening suppliers.
Build for reuse across reporting cycles
How to structure naming, storage, and mapping logic so supplier data collected today can be refreshed and reused rather than rebuilt every reporting cycle.
