Explanation
Eliminate Waste is the lean/agile principle that directly targets inventory as a source of hidden errors. In lean thinking, inventory - including partially completed work, unmerged code, or untested features - is classified as waste (muda). Inventory sitting idle obscures defects, creates handoff problems, and delays feedback. Eliminating waste means reducing work-in-progress and moving toward continuous flow so that errors surface quickly rather than accumulating undetected. The other principles (Fast-Flexible-Flow, Optimize the Whole, Deliver Early and Often) are related but do not specifically target inventory as a waste category.
