I read the whole article. It is designed for certain types of task, and it is not appropriate to others. For example, sometimes my tasks involve, "travel to the city and speak with Joe." "Travel to the city" takes 40 minutes. It should not be split into two work units with a break in between. Further, "speak with Joe" would not be splittable. How am I going to say, "Joe, when the timer rings, we are going to get up and not talk to one another for 5 minutes." However, for desk-work it might help me. I have to stop every 20 minutes and take a 5 minute break anyway due to RSI. Using this interval as an atomic unit for task completion, recording, and estimation may be useful.
