It's an interesting point you mention regards Consultants. I've been operating as a strategic consultant for the last 2 years, but purely as a one-man band. At every step of the way, I've been constantly asked to assist with the implementation/execution as well (since I only focus on the planning element).
The thing is, I read a book called Million Dollar Consulting by Alan Weiss, and he always stated that consultants don't ever do execution, that they only focus on the thinking/strategising side. I'm now starting to think that was a big mistake and that I should indeed form a team.
Any thoughts or suggestions in light of the above?
