What makes it a business is that the skills and problems are more unnamed than not. If it was really that well-understood, someone would be trying to automate the heck out of it. The business only has to get far enough to deliver a product or service; its solutions are basically guaranteed to be 80% - instead of telepathy we have cell phones, instead of teleportation we have vehicles. Et cetera. Thus, grit. The combination of building from what you already understand, and being willing to experiment with what you have, is usually enough to make iterative progress, and occasionally it results in an unexpected innovation.
