That's a difficult question to answer.
I think we saw, in some of the contracts we reviewed, that they felt that once one contract had been issued, McKinsey would then have knowledge of the business, which then justified their being more efficient and effective in future contracts. But I think that could be said about any vendor. That's why I do believe that the first requirement to determine exactly what you're hoping to accomplish with a procurement process is that it is well thought through and well documented. Then you pick the most appropriate tool that is available—and sometimes they are competitive and sometimes they are not—to accomplish that outcome.
