In this reflexive report I detail my process for creating effective documentation for computer game design. I begin by explaining the background of my work, the goals and limitations I had during this thesis, my goal being to find good practices about writing effective design documents. One chapter is dedicated to the methods I used while writing both the documentation, as found in appendix A, and this report. I then document and discuss my work process and the choices I made as well as the basis of those choices, I also reflect on the effects of my changes. My analysis is based on my iterative work, external sources and private experiences. Based on my work I conclude that creating documents that are easily searched and that only document the information crucial for implementation leads to effective abstract design documents.
