GRAMMAR POINTS TO REMEMBER
In formal business writing, such as explaining project delays or failures, how you phrase the problem greatly impacts how the Board or the client perceives it:
- The Objective “Such a/an” Noun Phrase:
- Saying “The project was so complex that we failed” places the focus on your reaction to the project.
- Saying “It was such a complex project that it required more time” places the focus objectively on the nature of the project itself.
- Rule: Use Such + a/an + Adjective + Singular Countable Noun (e.g., such a monumental task, such an unprecedented challenge).
- Using “So” for Direct Impact:
- Use So + Adjective/Adverb when you want to highlight the severity of a specific condition without wrapping it in a noun.
- Example: The regulations were so strict that we had to pause.
- Quantifying the Overload:
- When the delay is caused by sheer volume, use So + many/much/few/little.
- Example: There were so many dependencies and we had so little warning.
