Abstract:
The objective of this study is to understand the interrelations among the micro processes which comprise sensemaking
(WEICK, 1995) and the construction of trust (LUHMANN, 1996) in unexpected events. Unexpected events transcend
routine and planning orders. However, when they happen, they demand from the organizations solutions as efficient and
effectual as those programmed events. The methodology consists of the analysis of six semi-structured interviews and
Conversation Analysis (CA) of the main extracts of the conversation between the agents and the supervisor from the
beginning of event until its conclusion (recorded in real time). As empirical evidence, an unexpected event at the Operations
Center of the Brazilian Electrical System (COS) of an important Brazilian state, on September 24 and 25, 2009 is
investigated. The conclusion is that there is an interrelationship between micro processes of sensemaking, considered as
ambiguity, experience and interactions, and the micro processes of trust, considered as complexity, familiarity and social
behavior.
