ABSTRACT
The objective of this chapter is to give you a better feel for how the products of a CWA
can be used in both systems design and research. As we mentioned before, this book is
primarily about analysis, but work analysis is a means, not an end in itself. During the
last five chapters, we have pointed out how CWA can be used to derive requirements for
the design of sensors, databases, constraint-based procedures, automation, context-
sensitive interface mechanisms, human-computer dialogue modes, dialogue process
flows, organizational structures, training programs, selection criteria, and interface forms.
It is important to illustrate some of these connections to systems design in concrete detail
so that the payoffs that arise from the effort that is invested in conducting a CWA become
more tangible. The first part of the chapter deals with implications for design by showing
how the concepts in CWA have been used to design innovative interfaces for library
