Score each criterion from 1 (not in place) to 5 (fully ready). Items marked Critical can block a Go decision on their own. Everything runs in your browser and nothing is sent anywhere. Don't enter confidential information.
Limits: scores are human judgements, so the tool structures a go/no-go discussion rather than replacing it. Thresholds and weights are illustrative and should be agreed with stakeholders. A real review also needs evidence behind each score, such as test results, sign-offs and attrition data.
