Martin Bergaus investigated Service Delivery Platforms (SDP), focussing on their challenges and design aspects from a user's perspective. Qualitatively he incorporated user experience in SDP research, developing a Grounded Theory (GT) then set out parameters needed when developing SDP investigations from a user viewpoint, before technical implementation. This study indicates usability factors for future SDP systems and contributes to the exploratory framework represented by the six GT categories. The results of this study benefit Information Systems (IS) experts developing SDP based ICT systems and those interested in practical applications of GT.  Contents Literature Review Research Methodology Presentation of Findings Model Development and Discussion of the Results Conclusions  Target Groups Researchers and students in the field of IS research, SDP researchers, usability researchers, and qualitative researchers using Grounded Theory Methodology (GTM) Practitioners in the field of Ubiquitous and Cloud Computing, practical application of GT  About the Author Martin Bergaus, Ph.D., teaches as an associate lecturer at the University of Applied Science and Technical University in Vienna. His current research interests focuses on a qualitative research using Grounded Theory in the field of Information Systems. He has professional experiences within the ICT and company start up.
