Collaboration largely determines ERP development success but is fluid with difficulties. We propose them originating from collaborating actors’, such as developers’ and clients’, diverging perceptions. Identifying these perceptions is difficult

Information systems (IS) implementation is essentially a social activity. Technical solutions emerge from the humans’ social interactions and cognitive processes and are then planted into the IS users’ subjective realities. These interactions are
