The basis for successful RE is a common understanding of the terms used. The CPRE Glossary covers the core terms of Requirements Engineering—it is the central reference work across all CPRE modules and levels! The RE@Agile Glossary supplements the CPRE Glossary with terms for Requirements Engineering in an agile environment.
The glossaries are also available in various languages for download.
