Learning from Interruptions

New insight into focus and estimates based on Tempo interruptions. slack

Startling result: more focus means less predictable.

This is coding's version of Learning from Incidents.

interruption ⇒ focus ⇒ learning ⇒ value

routine ⇒ tempo ⇒ predictable ⇒ obvious

Note: in this usage the interruption is internal to the process. Peopleware made a big deal of Concentration Interruptions such as the phone ringing. That was a bigger deal in an older style of programming that took place mostly in the head instead of on the screen.
