If I'm working with a coworker or a client and they ask me something that I don't know the answer to, I will typically say, I need to look into that further, I'll get back to you, and then I'll go ahead and figure, you know, ask the right point of contact, what the answer is to that question, and then follow up, you know, with that client or with that customer with an answer to their question. Or if it still can't be resolved, then to just keep in contact with the customer or the client to say kind of what steps we're doing or what steps I'm going through in order to kind of escalate their issue up to a higher level of management if it's required.
