What is a Dynamic Purchasing System (DPS)?
An open list buyers run over several years, and why it suits smaller suppliers. Here is the plain-English meaning, why it matters and what a supplier should do next.
Definition
Definition is a procurement concept suppliers need to understand before relying on it in a live submission. In practical terms, it affects how an opportunity is advertised, assessed or awarded. Always check the tender documents because the buyer's stated procedure and definitions govern that competition.
The practical test is simple: can an evaluator or colleague trace the decision back to the source and understand what happens next? If not, add the missing requirement, owner, evidence or deadline.
