The results of the analysis are transferred into formal or technical concepts: e.g., a system architecture, a system specification, or a design concept. Both, a deep understanding of the domain and a broad technical know-how are needed.
The conceptual or technical feasibility is examined in relation to the requirements that were worked out in the analysis phase. Alternative solutions are compared regarding cost and benefit. It is decided which requirements, aspects or factors will be considered in the final concept and which will not. For the sake of a manageable concept or solution, often the results of the analysis phase are simplified, and some special cases may get eliminated. In this phase, diversity requirements and considerations of time and effort may get into conflict. There is an inherent risk of losing sight of relevant gender and diversity aspects.
