  Although integrating UX practices into software development processes is a
type of Software Process Improvement (SPI) activity, this has not yet been
taken into account in UX publications. In this study, we approach UX
integration in a software development company in Sweden from a SPI perspective.
Following the guidelines in SPI literature, we performed a retrospective
meeting at the company to reflect on their decade of SPI activities for
enhancing UX integration. The aim of the meeting was to reflect on, learn from,
and coordinate various activities spanned across various organizational units
and projects. We therefore supported the meeting by a pre- generated timeline
of the main activities in the organization that is different from common
project retrospective meetings in SPI. This approach is a refinement of a
similar approach that is used in Agile projects, and is shown to improve
effectiveness of, and decrease memory bias. We hypothesized that this method
can be useful in the context of UX integration, and in this broader scope. To
evaluate the method we gathered practitioners' view through a questionnaire.
The findings showed our hypothesis to be plausible. Here, we present that UX
integration research and practice can benefit from the SPI body of knowledge;
We also show that such cross-section evidence-based timeline retrospective
meetings are useful for UX integration, and in a larger scale than one project,
especially for identifying and reflecting on 'organizational issues'. This
approach also provides a cross- section longitudinal overview of the SPI
activities that cannot easily be gained in other common SPI learning
approaches.
