Introduction: The aging of the population in Western Europe has led to a substantial increase in home-based care services. These services are quite simple in nature, but very complex to provide in the community. Little is known about how they are actually provided. Aim: Using trajectory and arc of work analysis, the aim of this qualitative sociological study is to understand how support and care activities are ran in their local context. Method: Eight home care situations were observed during a period of three months, in three different home-based centers of one French-speaking canton of Switzerland. Data collection included semi-structured and ethnographic interviews, service documents, key reference documents, and observation of working practices in natural settings. Results: Data analysis showed that the standardization of evaluation practices—and a common frame of reference oriented by administrative principles—limited the possibility of problematizing situations as a whole, from a caring point of view. Consequently, services are mainly delivered in a fragmented way—and work organization is presently driven by compliance concerns. Conclusion: The ongoing standardization of care processes is a challenge to individualized and community-based care.
