Deliver value in small increments rather than large batches. Get the work in front of the customer early and often. Prefer working results over exhaustive documentation. Adapt the plan as evidence comes in instead of forcing reality to fit the plan. Trust cross-functional teams to organize the work themselves.
Agile inherits directly from lean manufacturing: small batch sizes, pull instead of push, visual management, retrospectives that mirror Hansei. Kanban boards moved from Toyota's shop floor to software teams almost unchanged. What differs is the domain, knowledge work instead of physical parts, but the underlying belief is the same: shorter cycles expose problems faster and let the team improve continuously.
Agile shows up in factories through Kaizen events, cross-functional problem-solving, iterative rollout of digital tools, and product development that ships prototypes early instead of waiting for a perfect specification. It works well anywhere the answer is not fully known in advance and the fastest way to find it is a series of small, cheap experiments.
Agile is less a specific methodology than a mindset: small steps, visible progress, honest feedback, disciplined adaptation. Combined with lean, it gives teams both the tools and the culture to improve without waiting for permission or perfection.
