This thesis was written at the same time, as a project of creating an instruction card of the RADAR-iTE in cooperation of the author and Rouven Küster took place. Rouven Küster administered the communication between the author and the collaborative Police Department of Berlin. At the beginning of the project, there was no previous form of an instruction card in use, but previous measures nationally, were conducted by using Wiki service to spread information during year 2017. The purpose of the instruction card was to present the procedure of making Violent Extremism Risk Assessment, using the RADAR-iTE as assessment tool. The objective of the thesis was to develop an instruction card for operational and educational purposes. The instruction card is meant for people who are using the risk assessment tool for the first time or are having their first case and need reminding and concentration of using RADAR-iTE assessment tool. As the instruction card was prepared, practice research was conducted to collect information of the RADAR-iTE before prototyping of the instruction card. For the practice-based development, qualitative research was conducted. Practice research was used to recognise the RADAR-iTE as an assessment tool to help recognise Militant-Salafis by a two-stage assessment. The practical part of the thesis is instantiated by three prototypes of the instruction card. The prototypes were developed in scope of the PDSA cycle, to help recognise needed development of the structure of the instructions and the graphics of the instruction card. The prototypes were presented to representatives of the Police Department of Berlin in a meeting which was administered for the decisions of the design and information. The meeting was additionally administered for assessing the need of more isolated development of the instruction card prototypes, and to scoping of theory found by the practice research.
