Create a system, targeting end-users (patients), that facilitates the recording and commenting of heart arrhythmia events. Describe your system in a Lean Canvas (focusing on the patient-side and backend interactions), describe the behaviour in a User Story Map, and create at least two different prototypes as Wireframes (in a Story Board) and preferably also as executable prototypes, following Google Material Design.

Perform an A/B test with multiple participants and record your findings using either Wireframes (maybe cut out to individual frames) or better, your executable prototype.

Upload one PDF per group containing 1) your Lean Canvas, 2) User Story Map and 3) both Wireframes with a) annotated microinteractions (triggers, rules, feedback) and b) external interaction and 4) a link to your executable prototype. Also 5) add a validation slide that describes a) what you validated, b) how you did c) a summary of the findings, and d) any additional observations learned.
