Kiwi programmers have amazing attention spans. When we are in “brain-dump” mode the code is flowing, the fingers are flying and the tests are running alongside.
We work until this pair-days work is done. Sometimes we finish before 5pm; sometimes not. It is not about overtime but about coming to natural breaks.
We call in the customer (or Nominal User) to sight our tests and “sign” them off.
We do our off-line stuff, e-mail, and buffer our time by cleaning up the documentation.
Next morning we begin with our stand-up meeting for the next task. Thus while urgency is accepted, overtime is at our discretion.
We are productive when our minds are screaming along and not when our emotions are jerked about by pressure and abuse.
