Many companies in the digital space often fail due to missing mechanisms for a continuous innovation of their product or product portfolio. The bets placed are too high, and a strategic focus with structured risk assessment does not take place.
For exactly this reason I would like to recommend the recently published book "Testing Business Ideas", published by Strategyzer around Alex Osterwalder. The Strategyzer team has already introduced valuable tools such as the Business Model Canvas or the Value Proposition Canvas. In Testing Business Ideas, the focus sharpens on the principle that every business hypothesis — no matter how small — must pass through a test. At the same time, it ensures that business ideas and hypotheses are created in a structured way and run through the full loop of business design and test.
The book offers a comprehensive toolbox for this purpose, suited to every business situation.
