Their top answer is always - Quality. As long as a consultant's fees are in an acceptable range, price isn't a major concern. Availability of specific skills isn't a problem, either. No matter what skills are needed, they can usually find them in the marketplace. A gap in the supply of good people isn't a concern.
Quality is what they want.
They want Information Technology vendors to do the job right. Do what's expected. And do it right the first time. Over and over again. Allen Consulting Group is in business to sell solutions, not just time.
