In RE: A well-argued request for changing one or more ↑baselined ↑requirements.
The CPRE Glossary
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 glossaries are also available in various languages for download.
