Selection of an improper test partner is a risk of outsourced testing that might not apply to distributed testing. Be sure to ask a prospective vendor what unique intellectual property and best practices it can bring to your project. You will want a team that has done it before and distilled its years of experience and success in completing projects into a set of best practices, accelerators, methodologies, and tool kits. Having these assets will help accelerate your quality efforts and reduce time to market.
