It sort of reminds of mechanical engineering, where engineers sketch out the problem solution, do the calculations, and make sure the solution works. Then, they supervise drafters or technologists to produce the actual final product of engineering, drawings (2D/3D, paper/CAD, whatever). Of course, that's in larger orgs. Smaller places will typically have an engineer doing everything.
