I think the key would be to speak to what you are able to accomplish as a practitioner. If the mechanics are too complicated or lengthy to explain to everyone, then don't. I would focus on explaining the issue and then describing how your solution would fix it. Think about flying to the Moon, people wanted to do that and a dream was sold to the crowd by simply saying 'we will do it', most did not ask how the rocket would work! Let me know if this helps?
