Some differences exist between the terminology used in IEEE Std 14143.1-2000 and that in IEEE Std
610.12-1990, IEEE Standard Glossary of Software Engineering Technology, because the terminology of the
International Standard is specialized to its particular purpose. The reader should use the local definitions in
IEEE Std 14143.1-2000 where there is a difference with those of IEEE Std 610.12-1990. In some cases, the
definition in IEEE Std 610.12-1990 may provide further clarification. It is important to keep in mind,
however, that full compatibility of definitions has yet to be achieved in the evolving field of software
engineering.
