Progress in manufacturing is measured by the production of high quality goods. The unit of progress for Lean Startups is validated learning-a rigorous method for demonstrating progress when one is embedded in the soil of extreme uncertainty. Once entrepreneurs embrace validated learning, the development process can shrink substantially. When you focus on figuring the right thing to build-the thing customers want and will pay for-you need not spend months waiting for a product beta launch to change the company's direction. Instead, entrepreneurs can adapt their plans incrementally, inch by inch, minute by minute.
Technical debt describes what happens when software or hardware is built quickly to validate hypotheses and find early customers. This quick and dirty development results in software that can become unwieldy, difficult to maintain and incapable of scaling. Organizational debt is all the people/culture compromises made to “just get it done” in the early stages of an innovation project. You clean up technical debt through refactoring , by going into the existing code and restructuring it to make the code stable and understandable. You fix organizational debt by refactoring the team, realizing that most of the team who built and validated a prototype may not be the right team to take it to scale but is more valuable starting the next innovation initiative.
