Expert writing Tips
Best practice
Consider the formality of your writing. While "a system in which" is generally acceptable, more formal contexts might benefit from alternatives like "a framework wherein" or "a mechanism through which".
Common error
Avoid using "a system in which" without clearly specifying what the system entails or how it operates. Vague references can confuse the reader. Instead of saying, "The organization has a system in which decisions are made", be specific: "The organization has a system in which all decisions are reviewed by a committee before implementation".
