Forrester fielded 85 formal client inquiries on the topic of vendor management and the development of the vendor management office (VMO) over the past 12 months. These inquiries come from a variety of roles across organizations, not just from sourcing and vendor management (SVM) professionals, as business units become more capable of bypassing sourcing and IT's third-party vendors play an increasingly strategic role for the business. Overall, most of the inquiries focus on understanding the value proposition of vendor management and the best practices for building a VMO. Forrester views the VMO as a critical response to the growth of third-party IT relationships, which should merit the attention of every IT organization with strategic vendor relationships.
