What's inside

The whole method, start to finish.

Why most bake-offs pick the wrong vendor

The three failure modes that measure the demo instead of the deployment, and how to design each one out.

The four shapes of a bake-off

RFP, build-vs-buy, head-to-head, incumbent displacement, and the decision rule each one demands.

The seven-step method

From defining "good" before any demo to deciding on the weights you locked first. The order matters.

Mining your production calls

Turn real calls into the scenarios, behaviors, personas, and background noise your shared test suite needs.

Reading the scorecard

Score every vendor on the same evidence, so no single demo can move the goalposts after the fact.

Run it in rounds

Cull a wide field, then score how fast finalists fix what you flag, the strongest signal of the partnership to come.
