The appreciation of good user interface have been increasing for a quite a while in many areas. People do not want to spend their time pondering what the user interface is all about. In user interfaces of machine automation companies, safety is one of the most important aspects. When big machines are handled, a mistake can lead to hazardous situations and unclear error messages can cause incorrect interpretations. That is why the meaning of good user interface is significant. Sandvik’s user interface design process diagram was out of date and it was supposed to be replaced with a new diagram. In this thesis the new diagram is created. The diagram defines what phases belong to user interface design. In addition the new diagram has a list of people who are part of user interface design and their tasks in it. For the creation of the new diagram, existing user interface design methods were studied and they were utilized in suitable parts in the design of the new diagram. Additionally Sandvik’s employees were interviewed. It was examined in the interviews, what would be good to have in the new diagram to make it as useful as possible. According to design methods, interviews, and the old diagrams the first version of the new diagram was created. It was verified by interviewing more people. The interviewees were able to freely express their views about the diagram and its possible flaws. The interviews made clear that the diagram includes all of the parts in user interface design fairly well. However, some suggestions for improvement were discovered in the interviews. According to the second round of interviews the diagram was edited to its final form. The outcome of this thesis is user interface design diagram that is customized for Sandvik’s needs. The diagram consists of the main diagram which includes the phases of making user interface design. The phases are research, concept design, design, implementation, support and updates. In addition, there is more information about different parts around the main diagram. There is argumentation about why user study would be useful to do, examples about design models that could help with design are given, it is listed where things should be documented, and tips for making the project are given. Additionally one of the most important aspects of the diagram, roles connected to user interface design and their tasks, are listed.
