Woke up at 5.30 so crunched some numbers to help some stakeholders understand the impact of high work in progress limits. The team commits 60% of its time to planned project work. In practice, they probably do more, but this gives them time for team activities and unplanned work. 60% of one month is about 100 working hours. If someone has five projects, and spreads their time so that the most important project gets the most time, it works out at 30 hours for the highest priority, 25 hours for the second priority project, and just 10 hours for the lowest priority project. That’s less than two days of working time.
