You don’t know what you don’t know.

Lack of understanding

  • Define what needs to be done to complete the piece of work
  • Plan how you will go about doing the work with the technology being used

Changing business requirements

Outside influences

  1. Add in some padding to your estimate to allow yourself some extra time in case of small blockers.
  2. Try and identify any potential blockers before estimating.
  3. Raise the blocker to make the relevant stakeholders aware of risk to the work being delivered.
