Tiivistelmä
CGI Suomi Oy has developed a web application for supervisors, HR Timeline, which is used to accept or reject overtime and on-call hours inputted by employees. The web application is not compliant with the current company UI guidelines; The UI components are different looking, and the colours are wrong. Additionally, the application was developed in a tight schedule without consulting the future users, resulting in bad usability. CGI wants to improve the usability of the application and bring it up to standard with the company UI guidelines in order to improve the satisfaction of current users while making it easier to sell to new customers. To achieve this, key interface elements are examined with the help of usability metrics. The application and its interface elements are also compared and contrasted with other similar applications to see what kind of elements and user flows would be good to have.
The study is divided into two main parts, first usability test and second usability test. First, usability testing was used to evaluate the current state of the application in terms of usability. Questionnaires and user interviews were used to map the subjective satisfaction of the usability of the application. Results of the usability tests, questionnaires, and interviews were analysed, and necessary improvements were implemented in a clickable prototype. In the second part, the prototype was used in another usability test to determine if the improvements were good and the usability of the application was improved. The overall results were evaluated using usability metrics identified in the literature review. In the end, suggestions in terms of usability were made for designing or improving a similar application.
Based on the results of the first usability test, there were many aspects and interface elements of the application that showed low levels of usability. Selection of persons and time span as well as approving or rejecting more than one timestamp pair at a time were among these. The study shows these problematic parts had better levels of usability after fixing them in the prototype.
