Defensive estimations and time management

Defensive task estimations

  1. Break the project into tiny tasks. Tiny tiny tiny. Smaller than that. Each task should have a clear definition of done.
  2. Give each tiny task an estimation. No tasks should take less than 2 hours, no task should take more than 2 days, 3 if you must.
  3. Sum all of that up and add 20% buffer.
  4. Add on-call duty, time off, holidays etc.
  5. Add another buffer for customer bugs and unplanned interruptions and delays.
