Systematic guidance on usability methods in user-centered software development

摘要

Context: In order to ensure usability, it is necessary to schedule activities and methods to be applied throughout different stages of the development process. There exists a substantial number of usability methods to be applied in user-centered software development. However, the application of each usability method largely depends on specific constraints that should be closely considered. Even so, these constraints are not always known beforehand, remaining unidentified or under uncertainty at early stages of the project.
