Expert writing Tips
Best practice
Before using the term "a formal specification," verify that the specification is indeed formally documented and follows a recognized standard or methodology. This maintains credibility and avoids misrepresentation.
Common error
Avoid using "a formal specification" when referring to preliminary or undocumented requirements. Instead, use terms like "initial requirements" or "preliminary guidelines" to accurately reflect the level of formalization.
