The Bell Mason Diagnostic is the most scientifically designed/architected/backtested framework to apply a 'real estate inspection roadmap equivalent' for the startup lifecycle. Also designed by Coopers & Lybrand, it also represents the best/only 'GAAP-equivalent' reporting structure for startups, to allow for objective measurement of startup status...to take the 'art' out of valuation, and allow for objective monitoring of status/progress post-investment.
Btw, it is the structure of our reporting/analytics service for startups, and Gordon Bell is an investor in AngelSpan.
