Kanban seeks to reduce
multi-tasking and context switching. Here is a quick and easy exercise to experience the effect of
multi-tasking.
Have each participant divide
a page into 3 columns with headers as shown:
Start a timer and have each fill out the columns by hand, working from left to
right, one row at a time (one entry in left column, then 1 entry in center column, then 1 entry in right column, then 1 entry in left column...). Note that the middle column is Roman numerals. Stop the timer when finished. Note each person's time.
Now create the same table again on a blank
sheet. This time start the timer and fill out the columns vertically
(fill out the left column completely first, then the middle column, then the right
column). Stop the timer when finished. Compare the result with the times from the
first table. This is the effect of multi-tasking vs. focus.
