Best practice
When using "requirements which", ensure the clause following "which" provides specific, non-essential information about the requirements. If the information is essential, consider rewriting the sentence for clarity.
Common error
Avoid using "that" in place of "which" when introducing a nonrestrictive clause (a clause that adds extra information but isn't essential to the sentence's meaning). "Which" is more appropriate in these cases. For example: "The software has certain requirements, which are outlined in the user manual."
