When it comes to solving a problem at work, that would all depend on what exactly the problem is. Is it a problem with one of the clients? Is it a problem with a potential client? If that is the question, I would basically refer to my resources that usually the company does make available to you, your resources, whether it be online or notes that I've taken. If the problem is with a fellow staff member, I would definitely do my best to take it to a superior in a non-confrontational way, of course.
