A supplier presentation may describe many capabilities. A purchasing decision needs evidence connected to the actual work, location and requirements under consideration.
ASQ's supplier-quality resources address managing supplier capability and performance within the supply chain. ASQ — supplier quality.
Connect evidence to the purchase
Ask which site and process the evidence covers and whether it relates to the proposed product. Keep a general capability statement separate from evidence about the actual material or construction. Neither a company photograph nor a broad quality slogan answers that question.
Review performance over time
Define what information will be reviewed during supply and how exceptions will be handled. A one-time selection exercise cannot establish every future delivery result. Use observed performance without silently changing the original requirement after a problem appears.
For a plush project, the useful supplier record is focused and current. It shows why the supplier was selected for the particular work and what evidence still needs to be provided.
