Sourcing · The supplier list · Element
The performance
How each supplier has actually performed against their terms.
The part
What it is
On-time delivery, quality and responsiveness, tracked over time rather than remembered.
Performance history is what makes a sourcing decision evidence-based rather than a matter of who last caused a problem.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
