No. When you are structuring the framework, take the time to think it through, before telling your interviewers. Chances are that when you first start working on the structure you need sometime to collect your thoughts and organize them properly. If you think out loud at this stage, you would likely sound very random and unstructured to your interviewer. This is a time in the case that you can take the time to do some quiet work, take the chance and don't waste it.
