The Invest Principles in Agile is a mnemonic that helps teams remember the key characteristics of a well-defined user story. The acronym INVEST stands for:

- Independent: User stories should be self-contained, allowing them to be developed and delivered independently of other stories. This helps in prioritizing and scheduling work without dependencies causing delays.
- Negotiable: User stories are not contracts; they should be flexible and open to discussion between the development team and stakeholders. This allows for adjustments based on feedback and changing requirements.
- Valuable: Each user story should deliver value to the end-user or customer. This ensures that the team focuses on features that provide real benefits rather than just technical tasks.
- Estimable: User stories should be clear enough to allow the team to estimate the effort required to complete them. If a story is too vague or complex, it may need to be broken down into smaller, more manageable pieces.
- Small: User stories should be small enough to be completed within a single iteration. This helps maintain a steady flow of work and allows for quicker feedback and adjustments.
- Testable: Each user story should have clear acceptance criteria that allow the team to verify that the story has been completed successfully. This ensures that the delivered functionality meets the expected standards and requirements.

By adhering to the INVEST principles, Agile teams can create user stories that are well-defined, manageable, and focused on delivering value to users. This leads to more efficient development processes and better outcomes for projects.
