What's Next?
Once you have your Concept or Concepts, share them with your developers to make sure they make sense and that any points that need clarifying get resolved. Once this has been done, and the Concepts have been approved by whatever stakeholders are involved in the design process, you're ready to start development.
warning
Remember, Concepts should only contain things that end users should be aware of. They should not include implementation details.
Once the feature is ready for testing (as the Concept may need refining during the development process), the documentation and QA teams can be given the Concept, this will ensure everyone is using the same terminology, and is aware of the intended use-cases, states and behaviours.
