Using a Sequential Exploratory Design: Acquired Learning from the Development of a Smartphone-App for Individual Work Time Management.

This case elaborates on a sequential exploratory research design in which a quantitative method follows a qualitative data collection approach. It explains how this design can be implemented for the purpose of developing a smartphone app. In our case, the systematic review of existing apps was followed by qualitative interviews, during which the critical incident method was used to explore desired app features. These features were thereafter quantified and ranked in an online panel survey to understand priorities of potential app users. The case study explores how research can contribute to developing a technical solution for a current behavioral issue. The development and implementation process of a smartphone app for research purposes is also addressed. This process shows how workshops assessing usability and user experience were employed. The case discusses the value of the analysis of data provided by the app. Thereby, it provides valuable insights into challenges encountered frequently and lessons learned as a result thereof.
