| The aim of a CTSA is to develop as complete
and systematic a picture as possible of the trade-offs among risk,
competitiveness (i.e., performance, cost, etc.), and conservation associated
with the substitutes in a use cluster. To accomplish this, a CTSA employs a
modular approach to data collection and analysis utilizing "information
modules." An information module is a standard analysis or set of data
designed to build on or feed into other information modules to form an overall
assessment of the substitutes. A CTSA records and presents facts collected in
the information modules, but does not make value judgements or advocate
particular choices. This chapter summarizes the information module approach, describes the flow of information between modules, and provides an overview of the information modules currently in the CTSA methodology |
