When I'm asked a question, my reply often is "Well, there are two answers to that question: a short one and a long one (or a simple and complex)..." And that is because there are indeed two types of answers to many questions. I would call them definitive and process oriented. For example, "how long will it take to complete this project?". The simple answer might be "we do not know", the complex answer will be "we do not know, but here is how we can control and manage schedule for our project and make it possible to make certain commitments on dates depending on your goals".
Another perspective on these answers is that one of them is like "here it is" and another one is "oh, here is how you get it".Remember that saying that professionals do not always know all the answers, but they always know how to find what they need.
The matter of fact is that process oriented answers are just as important as definitive replies. Of course, we should always starve to simplicity, but if there is no simple solution, we should not abandon looking for complex ones.
