Frameworks can be fine. Using them before understanding what you make is not. At that point you often see it is faster and better to just make the parts you needed yourself.

Model as in you have a clear opinion on what your system does, why, how, and what it doesn’t do. A model evolves during development, which is where it becomes hard: You always need to make room for things you didn’t predict, so you need to adapt and refine the system model so that the change makes sense.

Adding features until a full system explanation consists largely of “but”, “and also” or “except”, things like “and you should ask Bea about how that part works” or the worst of all “this part can be anything”, is the opposite of working from a model.
