It is a truism that engineers see the world rationally... too rationally. Everything has one or more defined answers, all you need is to find the right set of solutions.
Because of that rationalist (using the term loosely) view, many engineers who have succeeded at product engineering, building the product, have failed at product development, designing and successfully marketing the product.
The problem with product development, and especially new product development, is that you never really know if your market is ready for your solution, and even if they are ready, if they will accept the product/solution, if they will like and adopt the design, if they can and will pay a profitable price, if the packaging and channels are right.
