One of Husqvarna AB's largest customer segments is Green Space Professionals (GSP). Being aGSP means taking care of a large variety of green areas such as golf courses, parks, and footballpitches. The diversity within the GSP profession makes it very important to adapt the productsto many types of people by involving the end user as much as possible in the productdevelopment process.The first part during the study has been to define usability based on theory and how this can beapplied to the current fastening device. The end user was involved in order to obtain a deeperunderstanding of areas of potential improvement that exist within the current fastening deviceand the consequences of these. A literature study was conducted with the aim of setting up atheoretical framework on human interaction with products. It became clear that the currentfastening device lacks features that satisfies certain aspects of usability. The connectionbetween the user and the theoretical framework contributed to a set of functional requirementswhich could be compiled into two important factors.The second part of the study was to apply these factors in a concept. The development of theconcept was carried out with classic tools for development of concepts and prototypes, whichinclude elements such as idea generation, screening, and prototype development.The third part was to evaluate how well the factors were applied through the concept andwhether these factors increased the usability of the concept.After the interview results were linked to the theory, it could be concluded that the twoimportant factors that needed to be improved, Time consumption and Response. A conceptwhich involves the developed factors and is based on the principle "quick release" wasdeveloped. With a complete concept and with the factors in mind, a user study was designedwith the intention of evaluating these factors and the usability in general based on thetheoretical framework. The user study consisted of four sub-parts, a visual test, a blind test, atime test, and a questionnaire. The results from the tests showed that a significant differencewas achieved regarding the two factors. This was further confirmed by the results from thesurvey, where it was clear that the participants also experienced the new concept as faster,smoother, and easier to understand.With the documentation presented, it can be stated that a change in line with what has beenproduced in this work, would with most certainty improve the usability of the fastening device.Keywords: Usability, UX-design, User experience, User study, User involvement, DoubleDiamond, Triangulation
