SMART tasks principles

SMART model is used for creating effective goals.

  • S - Specific
  • M - Measurable
  • A - Achievable
  • R - Relevant
  • T - Time-boxed

Indicators of progress. The team needs to agree on what that mean. Basically describe your vision of “Definition of Done”.


Stories are broken into tasks for the developers, but a customer should still be able to expect that every task can be explained and reasonable.


A good story can be estimated. We don’t need an exact estimate, but just enough to help the customer rank and schedule the story’s implementation.


A task should be limited to a specific duration. This does not mean that task must be estimated in hours or days, but should be an expectation of time frames.
