We investigate professional greenhouse growers' user experience (UX) when using climatemanagement systems in their daily work. We build on the literature on UX, in particular UX at work, and extend it to ordinary UX at work. In a ten-day diary study, we collected data with a general UX instrument (AttrakDiff), a domain-specific instrument, and interviews. We find that AttrakDiff is valid at work; its threefactor structure of pragmatic quality, hedonic identification quality, and hedonic stimulation quality is recognizable in the growers' responses. In this paper, UX at work is understood as interactions among technology, tasks, structure, and actors. Our data support the recent proposal for the ordinariness of UX at work. We find that during continued use UX at work is middle-of-the-scale, remains largely constant over time, and varies little across use situations. For example, the largest slope of the four AttrakDiff constructs when regressed over the ten days was as small as 0.04. The findings contrast existing assumptions and findings in UX research, which is mainly about extraordinary and positive experiences. In this way, the present study contributes to UX research by calling attention to the mundane, unremarkable, and ordinary user experiences at work.
