Although listed as an output from and an input to tasks associated
with the requirements discipline, this artifact can be updated at any time and
by any role as new terms are identified. The terms defined should be used according
to the recorded definitions in all project documentation so that all stakeholders
can clearly see that terms are being used consistently.
One of the primary decisions when developing this artifact is whether
to have all terms in a single glossary or to maintain terms in several glossaries,
business terms artifacts, or models. If terms are defined in multiple places,
you need to communicate all of those sources to the team and decide which take
It may be important, even in small projects, to reference and use existing
broader glossaries, business terms artifacts, or data models, where they exist.
Industry- and organization-wide glossaries may be referenced, and compliance
with such specific chosen standards may be required.
