> "Customer collaboration over contract negotiation" The distinction is more about how granular you need things. Do you need to negotiate every piece of business-logic and get signoffs on mockups up-front, and in the case of paying customer, rather than internal stakeholder potentially including placing them into a legal SOW? Or can you just agree to a bullet-list of high level functionality, and then establish a working arrangement to receive feedback and refinement. Build and MVP and get some use, then make it better. Likely the initial understanding of the requirements was flawed anyway, so being reactive to the change, with buy-in from the customer will be a better plan for success. But yeah, this might not work with physical products.
