Partner or GC?: The move from law firm partner to general counsel is not always the best choice
The selection of an attorney to serve as a company's general counsel can further a company's business goals significantly if the selection is well considered and draws from a pool of candidates with demonstrated strengths for the role. Some aspects of the role, though, may be under appreciated to the degree that they don't fit well with candidates from some pools.
For example, partners in law firms might find the role so different from that to which they are accustomed that the fit never works.
