This document outlines three perspectives on outsourcing using matrix models. Perspective I uses a matrix to show that outsourcing makes most sense for non-core activities that are complex, not critical to the business, and involve costs and risks. Perspective II looks at requirements for outsourcing providers using a matrix of flexibility, efficiency, knowledge, and reliability. Perspective III outlines a path for providers to develop competitive advantages through improving business processes, knowledge bases, economics, and investments.
