David J Anderson is interviewed by geekwire: How an automotive secret can make for better software.

Kanban is a way of visualizing invisible knowledge work activities such as software development, and limiting the quantity of work in progress. Limiting work-in-progress has several benefits: by avoiding over-burdening, quality is often significantly higher, while workers are happier and better motivated; delivery times are usually significantly shorter and far more predictable; priorities are often clear and prioritization decisions are simplified.

Kanban is also helping organizations improve their methods of working in an incremental, evolutionary fashion with reduced resistance to change and adopting new ways of working and collaborating together. Most managers appreciate that resistance to change is a major impediment to improving the economic performance of their business. Kanban is addressing this problem.
