Process consists of research and definition, ideation, prototype and test phases. Research was conducted to gain better understanding about the target audience and help define the problem. Ideation process helped brainstorm and list possible solutions. Selected ideas from ideation phase were developed into concrete prototypes and presented to the group of target audience for an evaluation. For full details, please refer to the paper or presentation slides.

Evaluation method
User evaluation was conducted with six people with following procedure:
– Conducted an interview with selected group of people about PMA system
– Asked them to use PMA Mobile App Prototype
– Asked them to provide oral feedback and comments about PMA system and PMA Mobile App
