"I en optimal värld skulle det inte se ut som det gör idag" : En kvalitativ fallstudie om vad som händer när kravdokumentation inte tas på allvar

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area. Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented. To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work. This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption. This study has also contributed a strategy for how the requirements may be submitted retrospectively in an efficient manner.
