Book review: The Principles of Product Development Flow

51PdVCFcp3L._AC_US436_QL65_Don Reinertsen wrote the book The Principles of Product Development Flow – Second Generation Lean Product Development.

A very complete book that describes the underlying principles that create flow in product development processes. After reading this book I now understand why in the SAFe methodology and corresponding training material there are so many references to this book. The eight major areas focus on practical methods to:

  • improve economic decisions
  • Manage queues
  • Reduce Batch size
  • Apply WIP constraints
  • Accelerate feedback
  • Manage flows in the presence of variability
  • Decentralize control.

I find many concepts and methods that are present in the SAFe framework too. E.g. economic objectives, cost of delay, economic batch size based on transaction and holding costs, queues, CFD, little’s law, variability, batch size, synchronization, Weighted Shortest Job First (WSJF) and many, many more.

The book follows the already mentioned eight major areas and you get for each area a set of principles explaining that specific area. Each principle is explained in detail including examples. In total, you get 175 principles explained.

Conclusion: this book is definitely a must read. If you want to improve or create the flow in your product development process start with this book. If you are using SAFe this book gives you a lot of background and explanation behind specific methods and principles that are included in SAFe.
