1. The Core Shift: Manufacturing Flow vs. Product Development Flow
Use visual management tools like Kanban boards to track hidden information queues across departments. 4. Exploiting Small Batch Sizes
Human beings and development teams cannot multitask efficiently. When individuals switch contexts between four or five different projects, they lose significant chunks of time to "cognitive switching costs." The Principles of Product Development Flow: A Deep
Limiting work-in-progress to maintain flow and prevent system overloading.
The Principles of Product Development Flow: A Deep Dive into Second Generation Lean and aims to eliminate waste
Product development is a process of continuous learning. The faster a team can validate an idea, the less capital they waste on incorrect assumptions.
This rule is disastrous in product development. The Principles of Product Development Flow: A Deep
Small batch sizes are only possible if testing, integration, and deployment are automated. Invest heavily in CI/CD infrastructure to remove manual handoff friction.

Product development flow is a holistic approach to product development that focuses on creating a smooth and continuous flow of work from idea to delivery. It is based on the principles of lean manufacturing and agile development, and aims to eliminate waste, reduce variability, and improve overall efficiency.
Reinertsen argues that product development is not a factory; it is a network of queues . You cannot manage it with manufacturing logic. You need the economics of flow .
