5 Design study I: How to create an ambulatory app for patients with BPP 159 Figure 2. CeHRes Roadmap for the development of eHealth technologies [87]. Reprinted with permission. The adapted model was coined the ‘Elements-Methods-Products [EMP]-framework’ (Figure 3). The left column of the model shows Garrett’s planes (the ‘E’ or ‘Elements of UX’). The green circles in the middle column are inspired by the research activities and methods of the CeHRes roadmap and represent the methods used in the study (‘M’). The right column shows the deliverables or products (‘P’) that will result from these methods. This study focuses on the ‘strategy & scope’ and ‘structure’ planes, the first two planes of the EMP-model. Purpose was on getting to know the context and users when developing an eCoaching application in mental health care while remaining agile in the design process. The main results or ‘products’ (P) obtained in these planes of designing (see Figure 3) that will be described in this paper are the Persona’s, User needs and Design requirements, and the Mental model(s) of the target user group(s). The process of developing a working prototype, which is at the heart of the ‘skeleton & surface’-plane, is not discussed here but is intended to follow in a future publication.
