Information. It is invisible, hidden in code, designs, and brains.
In your PDF search, look for the chapter on Economic View . It contains tables comparing marginal economic value versus urgency.

Every decision in product development must be tied to economics. Reinertsen advocates for using a single metric to align all choices: . Cost of Delay (CoD)
Every product development decision is fundamentally an economic trade-off. To optimize flow, teams must establish a clear economic framework that quantifies the cost of delays and the value of speed. Cost of Delay (CoD)
Teams must establish explicit WIP limits at every stage of the product development lifecycle. If a team has a WIP limit of three tasks in the "Testing" phase, engineers cannot pass new code to testing until the existing tasks are completed. This forces teams to collaborate, swarm on bottlenecks, and finish existing work before starting new work. 4. Exploiting Variability and Cadence Information
I can tailor a specific implementation plan or calculate a mock Cost of Delay framework for your scenario. Share public link
Understanding CoD allows teams to make rational trade-offs between development speed, product cost, product performance, and expense. For example, spending $10,000 on an extra server is a smart economic choice if it prevents a two-week delay that costs $100,000. Weighted Shortest Job First (WSJF)
To transition your organization from a traditional stage-gate mindset to a lean product development flow, follow these actionable steps: It contains tables comparing marginal economic value versus
The goal of product development flow is not to eliminate variability, but to . You can achieve this by: Creating short feedback loops to catch failures early. Keeping the economic cost of failure low. Buffering critical paths with capacity, not extra time. 4. Reduce Batch Sizes
When resource utilization approaches 100%, wait times increase exponentially. By focusing on the speed at which value moves through the system, organizations can drastically reduce cycle times and respond to market feedback in real time. The 8 Foundational Frameworks of Flow
