Task switching blur your vision

The document discusses the importance of limiting work in progress (WIP) to improve efficiency and reduce waste in processes. It emphasizes that while some activities add value, extended lead times due to task switching can be considered waste. The focus should be on identifying real bottlenecks rather than the wasted time caused by multitasking.

- 2. I´m sure you who reads this, understand the importance of limiting work in progress Still some of this could be useful in discussions with teams about this subject. Please do not hesitate to let me know if you think my reasoning is wrong or if you have any improvement suggestions to these slides.

- 7. Our focus path As we can only focus on one thing at a time. The path of your focus when performing multiple tasks could be visualized as below. As soon as we focus on one started activity all other activities experiences waste in the form of extended lead time.

- 11. Move this waste from blur to visible The waste from task switching is now minimized and visible in the queueing time. Now it´s possible to focus on real blockages and bottle necks which in the long run will lower the queueing time.
