Pillar 2 of 6
Tools
Decision-support calculators, planners, checklists, estimators, and assessment tools. Every tool publishes its methodology, assumptions, and limitations — no black boxes.
A CRI tool ships only when its methodology is public, its assumptions are documented, and its underlying data has been validated. Neither calculator meets that bar today, so neither will give you a number. We removed their output rather than let them look authoritative while a caveat sat further down the page.
The methodologies are published anyway, so they can be examined before anyone is asked to trust them. Read the CRI Methodology.
