On Monday, we have introduced Taguchi-san's idea on his bubble map todo list. He told me today on his further thoughts on his bubble map idea. He slices off the area in the bubble based on the stress you have eased on the task. Psychologically, this give you peace in mind and you will feel more positive as you cross off more area of the task bubble:
… Please not that how much you slice off is based on your stress (= mind-share) of the task, not based on the numbers of sub-tasks left.
Remember that a bubble represents the mind-share of your stress, not amount of the work you have to do (a bubble f lots of work with little stress is smaller than a bubble of one phone call with a lot of stress)…
One more good thing about the Bubble map – [idea * idea]
