The result is a framework that treats product development like a financial portfolio, optimizing for throughput and economic value , not just speed. For example, should you delay a project by

In manufacturing, inventory is visible. You can see piles of parts on a factory floor. In product development, inventory is invisible—it is information. It is the list of tickets in your Jira backlog, the un-reviewed code in a pull request, or the documents waiting for executive sign-off.
