Based on the perceived inadequacies of Steve Blank's "Investmeter" or thermometer for the Investment Readiness Level (IRL), I decided to develop the Business DNA Clock as a visual tool that shows a customizable roadmap for developing businesses that are built to last. We are currently using the Business DNA Clock to systematically develop, test, and validate ideas for our Business DNA Search Engine project. The Business DNA Clock is method or tool-agnostic: the Business DNA Clock can be used with tools such as the Experiment Board, Business Model Canvas, and Lean Canvas. The Business DNA Clock also comprehensively summarizes ideas in Eric Ries's "The Lean Startup" as well as Furr and Dyer's "The Innovator's Method." Try the Business DNA Clock and let's hear from you.
