This chapter provide a case and an investigation of how a particular mobile ICT support has been used within an established practice of homecare work. The discussion shows a perspective of how technology and practice coevolves and get enmeshed together. The importance of seeing the interface of either the mobile devices or the stationary computer as common information spaces is stressed, since the single-user interface the current system offers is not enough support for the collaborative activities the mobile workforce of homecare work is engaged in. The problem resides in this case in the relations to predecessors of the system, found in diaries and coordination tools. A modest suggestion posed by the author is that an understanding of the work maintaining the role of these predecessors can provide beneficial information for the future design of these technological supports.
