Co-create criteria and fair weights
Draft an initial list of criteria across outcomes, usability, integration, security, scalability, vendor viability, implementation effort, and cost. Facilitate a workshop to adjust and weight them, using techniques like MoSCoW, 100-point allocation, or Analytic Hierarchy Process where appropriate. Capture dissent and reasoning, then publish the final set. Invite peers here to critique your draft; outside perspectives often expose blind spots that insiders overlook.
