Your first mobile release starts with a need
How to scope a first release your team can review with users.
Choose one core journey
Describe who will use the app and what they need to complete. Prioritize a complete journey from entry to outcome before adding secondary features.
Consider the context of use
Ask where the app will be used, what connectivity is available and what data it needs to store. Test loading states, errors and recovery of a task.
Define how to review the result
Agree on observable criteria: completing the journey, understanding messages and recovering information. Review a working version with users and use their feedback to prioritize the next step.
