 - Flow state and productivity
-- Percentage of average hours worked per day as surveyed by IBM (Table 10.1)
-- Working alone is a minority, but **real work can be done when you are alone**, so you can't ignore it
-- In a noisy office, it is impossible for a programmer working alone to be in a **flow state**
-- Anything that distracts you reduces programmer productivity and significantly increases the cost of your project.

-- A true record of time spent on work: It is NG to analyze the accumulated flow time against the flow time required to complete the project on a physical labor time basis.

 - E factor (environmental factor)
-- Daily measurement of the E-factor formally acknowledges the idea that programmers need some uninterrupted time.
-- By pushing the E factor to the forefront, we can change the corporate culture in the direction of not interrupting work.

 → A corporate culture of uninterrupted time logging helps programmers have time to do real work
