At Toyota, waste (muda) is defined relative to a known value-creation flow: overproduction, waiting, defects — all of these are deviations from a flow that has already been found and works. A startup does not yet have a value stream — it is unknown what will prove valuable at all. Therefore, when lean thinking is carried into innovation, the category of waste is redefined: the main waste is work that does not produce knowledge about what is valuable. A product nobody wants is the ultimate overproduction: every kind of resource has been spent for zero value.
The scale of the waste is macroeconomic: over the twentieth century, the effects of labor-productivity growth exceeded the effects of job reductions — the economy found new uses for the hands that had been freed up. The result was excess productive capacity that firms did not know what to do with; some of it is wasted unproductively, including in failed startups. Thus, the question “what to do with excess capacity” becomes the entry point for the whole method: direct it toward the production of validated knowledge. A grounding caveat: for Ries, this is a generalization from a single example (the United States, +15% output), a background premise rather than a demonstrated claim.
The consequence is that flawless execution of an unwanted plan is also waste — and the most insidious kind. The distinction between resource and flow efficiency takes its most extreme form here: a team can be perfectly busy — and dead from a flow perspective, because the value stream has never been found. Busyness simulates progress.
The moral conclusion of the introduction is that it is not labor alone that is wasted — “the passion, energy, and vision that people bring to these new ventures are resources too precious to waste.” What is at stake in applying lean to innovation is human capital, not unit cost.
Parallels in the vault (connections made here):
- Work in progress is a structural safeguard against the same waste: work waiting outside the system remains an option and does not create irreversible costs.
- Market failure is instinctively treated with engineering solutions — the mechanism by which this waste is produced: engineering amplification instead of validating need.
- Structural shifts from productivity growth — the macro level: where the excess capacity that gets wasted comes from, and why institutions like Lean Startup are needed to redirect it.
- A startup is steered by feedback, not guided by pre-launch calculation — the same waste at the level of a company’s fate: achieved failure, disciplined execution of the wrong plan.

If waste is work without knowledge, then the only way to eliminate it systematically is to make the production of validated knowledge the objective of the work. Redefining waste and redefining the goal are two sides of the same move.
