Understand FlowWhere do you spend your time? How much time is due to multi-tasking?Where do you wait?

% Flow Efficiency = (Work Time/ Lead time) * 100

Completion Time = 114 Days made up of 41 days waitingThis is only between different functions Does not include the wait time within a function% Flow Efficiency = (Work Time/ Lead time) * 100=(73/114)*100 = 64%
