In many organizations, the quality of the individual requirement statements and sets of requirements is often poor, not having the characteristics of well-formed requirement statements and sets of requirements. Correctness, completeness, consistency, ambiguity, feasibility, implementation, leveling, etc. are common issues. This puts a heavy burden on the design team to address and correct these issues. Given these issues, it is common for modern systems engineers to even question the need for text-based requirements. This paper discusses why text-based requirements are still important, their role in the overall systems engineering lifecycle activities, and identifies key issues in the current approach many organizations practice concerning requirement development and management (RDM) – especially how RDM relates to current model-based design and systems engineering approaches.
