Bland and Alexander Osterwalder, draw upon their vast experience and expertise in business model innovation to provide a practical and hands-on approach to testing business ideas. The authors emphasize the importance of experimentation in the early stages of business development. They argue that, too often, businesses fail because of a lack of proper verification and validation of their underlying assumptions. This is where Assumption Mapping comes in. It is a process that helps identify the most uncertain and impactful aspects of a business idea. Once these critical assumptions have been identified, the authors suggest 44 different types of experiments that can be conducted to verify and validate these assumptions. These range from simple online surveys to more complex pilot programs and minimum viable products (MVPs). The experiments are designed to provide real-world data and feedback that can be used to refine and improve the business idea. The authors borrow the Build-Measure-Learn feedback loop from Lean Startup methodology to emphasize the iterative nature of testing business ideas. They argue that this feedback loop should be at the heart of all business experimentation. Another important concept introduced in the book is the four types of Risk Profiles: Market Risk, System Risk, Execution Risk, and Stakeholder Risk. These risk profiles help determine the nature and extent of experimentation required for the business idea. The book also includes an Experiment Library, a comprehensive resource that guides entrepreneurs on how to design and conduct experiments effectively. This, coupled with the real-life case studies, provides a practical and hands-on approach to experimentation. The authors also stress the importance of collaboration with stakeholders in the experimentation process. They argue that involving all stakeholders ensures that the outcomes of the experiments are understood and accepted by everyone involved in the business. Finally, the book introduces Learning Cards, a tool designed to facilitate learning from the experiments and adjustments of the business ideas. They serve as a record of what was learned from the experiment and what changes are made as a result. In conclusion, "Testing Business Ideas - A Field Guide for Rapid Experimentation" provides a comprehensive, practical, and hands-on approach to the verification and validation of business ideas through experimentation.

Project to Product - How to Survive and Thrive in the Age of Digital Disruption with the Flow Framework
Mik Kersten

Key Facts and Insights from the Book The shift from project to product is essential in the age of digital disruption. The book introduces a new approach called the Flow Framework that enables businesses to align software delivery with business goals. The Flow Framework helps to measure the flow of value in software delivery and identify bottlenecks. Organizational structure plays a crucial role in the successful transition from project to product. Understanding and aligning the value stream is critical for success in the digital era. The book presents case studies from companies that have successfully made the transition from project to product. Surviving in the digital age requires a holistic approach that includes culture, process, and technology. Technology is an essential investment, not a cost center. Business leaders need to understand the principles of software delivery to drive the digital transformation. DevOps is a crucial aspect of the transition from project to product. In-Depth Summary and Analysis The author Mik Kersten begins by posing a crucial question that every business leader should consider: "Are you a digital disruptor or the disrupted?" In the era of digital disruption, Kersten argues that the traditional project management approach is no longer effective and that companies must shift from project to product to survive and thrive. The Flow Framework is introduced as a new approach that aligns software delivery with business objectives. The Flow Framework measures the flow of value in software delivery and helps identify bottlenecks, enabling businesses to continuously improve their software delivery processes. This is a key insight because it shifts the focus from output (how many features are delivered) to outcomes (the value those features provide to the business). The book emphasizes the importance of organizational structure in a successful transition. Kersten argues that the traditional hierarchical structure hinders the flow of value and that organizations need to adopt a network structure that supports the product-centric approach. This structure enables cross-functional collaboration and reduces dependencies, thus accelerating the flow of value. Another important concept presented in the book is the value stream. The author posits that understanding and aligning the value stream is critical for success in the digital era. The value stream includes all the activities, from idea to delivery, that deliver value to the customer. By aligning the value stream, businesses can ensure that every activity contributes to the business goals. Kersten also presents case studies from companies like BMW, Microsoft, and Tasktop that have successfully made the transition from project to product. These case studies provide practical insights and lessons learned that can guide other businesses through their digital transformation journeys. The author stresses that surviving in the digital age requires a holistic approach that includes culture, process, and technology. The book argues that technology should be treated as an essential investment, not a cost center. This is a profound shift from the traditional view of IT as a support function and emphasizes the strategic role of technology in the digital era. Kersten also argues that business leaders need to understand the principles of software delivery to drive the digital transformation. This includes understanding the principles of DevOps, a crucial aspect of the transition from project to product. DevOps practices, such as continuous integration and continuous delivery, enable businesses to accelerate the delivery of value and respond to changes faster. In conclusion, "Project to Product - How to Survive and Thrive in the Age of Digital Disruption with the Flow Framework" by Mik Kersten provides a comprehensive guide to navigating the digital disruption. The book offers valuable insights and practical guidance to business leaders embarking on their digital transformation journeys. It emphasizes the importance of shifting from project to product, aligning the value stream, adopting a network structure, and investing in technology. By adopting the principles and practices presented in the book, businesses can successfully transition to the digital age and thrive in the era of digital disruption.
