Information use by multi-agency teams in time constrained, uncertain and complex environments
This research investigates information practices issues in a time constrained,
uncertain and complex environment with a focus on emergency management. During
a major incident, commanders from the multi-agency emergency services such as
from the police, fire and rescue, and ambulance need to come together to manage
the incident. Depending on the nature of the incident, commanders involved in
emergency management vary; hence they meet on an ad-hoc basis. The literature
states that information should be shared among members of a team for coordination.
It is thus necessary to understand issues underlying information sharing. Also, one of
the major tasks in emergency management is to make decisions. From an information
science perspective, it is imperative to understand how information is used by
decision makers to make decisions. Thus, two research questions of interest are (1)
the issues which impact information sharing and (2) how information is used for
making decisions. This research takes an interpretive approach in which activity
theory is used as a methodological and analytical framework to address these
research questions.
Investigating the first research question, it was found that different components
impact information sharing. These components are grouped into six dimensions
providing more holistic understanding of the context, which is advocated in
information practices research. A model (the POSSTT model) is proposed as a
framework to study information sharing of such ad-hoc multi-agency groups.
Addressing the second research question, contributions are made to the ongoing
debate on types of decision making. In theory, type 2 (analytical) decision making is
promoted by many researchers; however, in practice it was found that in a time
constrained environment, decision makers may use a combination of type 1 (intuitive)
and type 2 (albeit not deliberative) decision making. A model for how experienced
people use information to make decision is proposed. In addition, a need is realised
for sub-dividing the experienced decision making model into an "experienced
decision maker" model, and, an "experienced and confident decision maker" model.
These contributions have practical implication for policy making and system design
