Lean Lego Game
The document describes a workshop on introducing lean principles to software development. It begins with an agenda and introduction to lean concepts. Participants then take part in hands-on exercises simulating production processes to experience issues like waste, uneven workflow, and inflexibility without lean. The exercises demonstrate how lean tools like kanban, pull systems, and multitasking can address these issues and improve flow. The workshop emphasizes that lean is not just tools but a long-term philosophy of continuous improvement respecting people.

Seen through client’s point of view Everything that is done but not necessary for the final product There is one visible kind of waste now: inventory How may houses produced x 25 Pieces x 1 Compare inventory accumulation with chart Show over/under production in the example Houses produced but not sold Houses demanded but not produced
