In which of the following does a project manager assign certain points towards various categories to judge the vendors?

A project plan documents how the project will be executed and controlled but does not define a vendor scoring mechanism.

Project analysis is a general term referring to evaluating project data or performance, not a vendor evaluation technique.

A screening system establishes minimum requirements to eliminate non-qualifying vendors but does not assign weighted points across categories.

A weighting system is a source selection technique in procurement management where the project manager assigns numerical weights to evaluation criteria such as cost, experience, and technical capability. Each vendor is scored against these weighted categories, producing a total score that enables objective, consistent comparison. This method reduces subjective bias and is a recognized PMI procurement tool.
