AB  - The German Biobank Alliance (GBA) aims to establish a cross-site biobank network. For this endeavor, the so-called Sample Locator has been developed ‒ a federated search-tool for biospecimens and related data ‒ forming the heart of its IT infrastructure.To ensure the sustainable use of such a tool, we included researchers as participants in an end user based usability evaluation.To develop a prototype ready for evaluation, we needed input from GBA IT experts. Thus, we conducted a two-day workshop with eight GBA IT team members. Focus was on the respective steps of a user-centered design process. With the acquired knowledge, the participants designed low fidelity mockups. The main ideas of these mockups were discussed, extracted and summarized into a comprehensive prototype using MS PowerPoint. Furthermore, we created a questionnaire concerning the usability of the prototype including the System Usability Score (SUS), questions on negative/ positive aspects, and typical tasks to be fulfilled with the tool. Subsequently, the prototype was pre-tested on basis of this questionnaire with researchers having biobank background. Based on this preliminary work, the usability analysis was ultimately carried out with researchers and the results were evaluated.Altogether 27 researchers familiar with sample requests evaluated the prototype. The analysis of the feedback certifies a good usability given the Sample Locator prototype was seen as intuitive and user-friendly, by 74
