Tab - Idea: for initial thought, revision, thesis, hypothesis, tag line, mission statement
Tab - Design: initially some rough drawings. Maybe dimensions with a goal.Probably cad files as final for this
Tab - Marketing: Commericals, pictures of product.
Tab - Prototype: The first one built. What is going wrong. What is going right. …updates? What needs to be done to ‘mass’ produce this by me?
Tab - Product: This will be where the money is made. Some cad files for free, some for sale. Subscription model. Sell products too.
