Crisis situations often led to profound professional transformations in terms of resources and practices. For example, COVD-19 has had major impacts on work environments with measures such as mandatory mask wearing, social distancing and containment episodes. Civil protection organizations (firefighters, emergency operations, healthcare) have not returned to their pre-confinement set-up since the end of the pandemic: their collaborative tools and professional practices (i.e. regular introduction of teleworking, new inter-departmental communication tools), that is their artifact ecologies, have evolved. My research aims to develop a better characterization of these evolutions by documenting and analyzing the evolutions of the ecologies of hardware and software artifacts of civil protection organizations, while and after the lockdown period. To achieve this, my study uses a qualitative research strategy based on semi-directive interviews and practical observations of inter-service training sessions. The lessons learnt from this aim at providing guidance for dealing with changes during crisis situations in the context of long-term cooperating organizations and their associated ecologies of artifacts.
