Personally, I think consulting works well, like contracting works well, when you have a specific requirement that the Consultant/Contractor can meet. We paid a lot of money for a software consultant once to produce an encryption library in .Net (packaging things, not inventing algorithms) and although he was clearly confident and reasonably competent, he wasn't able to produce it in 2 months. Once he left, I did it personally in 2 weeks on top of my CTO role. If we had planned this better, we would have only recruited someone with experience with the specific issues we had around DI and .Net encryption and it might have gone a whole lot better.
