I think this is why I as an a graphic and web designer don't always enjoy working on the projects of clients. Whenever they ask for a redesign they want me to visualize and build the solution for them. They don't always ask me to look at the problem and then think of the solution.
When I work on my own personal projects I get to do both, which is why the work I do for myself is miles ahead of the work I do for clients.
Over the years, I constantly remind my manager, clients, an colleagues to bring me in much sooner than they think they need to. When that happens, the problem definitions are much easier and the resulting solution works. Obvious, when you think about it. The analogy I use is that if we were constructing houses, then my role is both architect and builder.
