Software Vendor Selection Matrix

This vendor selection matrix makes a software buying decision easier to explain. Three vendors are scored against product fit, security review, implementation effort, three-year cost, and support quality. Required features and security have the highest weights because a low score in either area can outweigh an attractive price. The decision mode calculates the weighted total and ranks the options, but procurement should still inspect any non-negotiable requirement separately. A vendor that fails a mandatory security or compliance requirement should not win just by scoring well elsewhere. Define scoring evidence before vendor meetings, keep the assumptions with the decision record, and update the matrix if pricing, scope, or implementation plans change.

よくある質問

Why include three-year cost?

It captures recurring fees and implementation costs better than an initial price alone.

Can a vendor fail a mandatory requirement?

Yes. Treat mandatory requirements as gates in addition to weighted scores.

Who should score vendors?

Include the people responsible for users, security, procurement, and implementation.
