Feedback loops are the basis of learning and continuous improvement in agile development.
They can be found at several levels throughout different frameworks:

  • Compiler feedback
  • Pairing feedback from the pairing partner
  • Feedback from the automated test system
  • Daily feedback in the daily standup meetings
  • Customer or stakeholder feedback on the product in the review meetings
  • Feedback on the team work or the process in the retrospectives

Feedback is also an XP value.
