ABSTRACT
If Chapter 2 was concerned with the idea that taxonomies lie at the core of safety management (and databases in general), this chapter and Chapter 4 are about working with such taxonomies. In fact, in the simplest of terms, this chapter is about
input to
databases, and Chapter 4 is about
output from
databases. To use the standard terminology, therefore, this chapter is about the
reliability
of taxonomies,
and Chapter 4 is about the
validity
of taxonomies
.
