'Complex sociotechnical systems' are systems made up of numerous
interacting parts, both human and non-human, operating in dynamic,
ambiguous and safety critical domains. Cognitive Work Analysis
(CWA) is a structured framework specifically developed for
considering the development and analysis of these complex
socio-technical systems. Unlike many human factors approaches, CWA
does not focus on how human-system interaction should proceed
(normative modelling) or how human-system interaction currently
works (descriptive modelling). Instead, through a focus on
constraints, it develops a model of how work can be conducted
within a given work domain, without explicitly identifying specific
sequences of actions (formative modelling). The framework leads the
analyst to consider the environment the task takes place within,
and the effect of the imposed constraints on the way work can be
conducted. It provides guidance through the process of answering
the questions of why the system exists, what activities can be
conducted within the domain as well as how these activities can be
achieved, and who can perform them. The first part of the book
contains a comprehensive description of CWA, introducing it to the
uninitiated. It then presents a number of applications in complex
military domains to explore and develop the benefits of CWA. Unlike
much of the previous literature, particular attention is placed on
exploring the CWA framework in its entirety. This holistic approach
focuses on the system environment, the activity that takes place
within it, the strategies used to conduct this activity, the way in
which the constituent parts of the system (both human and
non-human) interact and the behaviour required. Each stage of this
analysis identifies the constraints governing the system; it is
contended that through this holistic understanding of constraints,
recommendations can be made for the design of system interaction;
increasing the ability of users to cope with unanticipated,
unexpected situations. This book discusses the applicability of the
approach in system analysis, development and evaluation. It
provides process to what was previously a loosely defined
framework.
