Don Reinertsen, batch sizes & WIP limits

During november we will at Bestrains Academy be hosting the Don Reinertsen two-day masterclass called “Achieving Product Development Flow” in Stockholm and Copenhagen.

The workshop covers the ideas contained in his bestselling book, “The Principles of Product Development Flow”. It focuses on proven leverage points and specific practical methods that have helped participants achieve as much as a 90 % reduction in cycle time.

If you are not already familiar with his work I recommend watching these two videos where he elaborates on two topics that he will cover in his class, the importance of understanding batch sizes and WIP constraints:

In this talk Don does a deep dive into the math behind batch size, the origin of the Economic Lot Size equation, and the implications of this equation for product developers.

Here Don takes deep dive into what makes WIP constraints work. You will find out why the Kanban technique of the Toyota Production System (TPS) is only one of many strategies that we can use to reduce WIP when it becomes to high.
