Gilbert, DavidFischer, HolgerRöder, Dirk2021-05-132021-05-132021https://dl.gi.de/handle/20.500.12116/36435Usability and user experience maturity models are used to evaluate the capabilities of an organization in order to provide an assessment of their ability to develop usable products. But, as the main focus of such models is on an all-encompassing organizational level, they are difficult to implement in more complex organizations with a wide range of diverse and interlinked projects. This paper presents a project related UX maturity model, which was developed at DB Systel to address this issue: the PUXMM. It takes into account the nested internal customer relationships between departments and subcontractors and applies a human-centered design approach. There are two practical application scenarios for the PUXMM. It can be used to determine the UX maturity level of an ongoing project and as checklist to align a project to a desired maturity level from the outset.enUX maturity modelUX capabilityhuman-centered designproject planningassessmentText/Journal Article10.1515/icom-2020-00292196-6826
