To remain consistent and reduce misunderstandings, a common vocabulary is established for all business terms, technical terms, abbreviations/acronyms, and actors that are relevant to the project. This common vocabulary should be used in all descriptions of the system.
It is important to use existing terminology of the business when possible. The
Application Development Glossary defines terms and acronyms common to the FSA. Any terms defined in the FSA Glossary do not need to be included in project level glossaries.
To identify common terms in the domain, consider terms used in the requirements, as well as the development team's general knowledge of the system to be built. Focus on terms describing the following concepts:
Each term in the common vocabulary should typically be described as a noun, with a definition. Terms should be in the singular form (i.e., "order" and "task", not "orders" and "tasks"). All interested stakeholders should agree on definitions for the terms.
