The only way that market research clients improve their business is by having the best fieldwork suppliers. It's that simple. Yes they can streamline their internal processes, train their staff to be the best of the best, sell their services to every blue-chip company in the world. But if they buy a poor quality fieldwork supplier it all falls apart. The power of the purchasing department's ability to make or break a project / researcher / company cannot be overstated. Whoever buys the best, wins.
