What it means
次第で means that a result or situation changes depending on a particular factor. It is commonly attached to a noun and emphasizes that the factor determines what happens. It is often used in formal or written explanations, announcements, and discussions of conditions, although it can also appear in ordinary speech.
Usage note
次第で should not be confused with the verb-stem construction 次第だ, which means “as soon as.” The related form 次第では means “depending on” or “in some cases depending on,” and adds a stronger sense that different outcomes are possible.
