The document discusses outsourcing vendor-managed service programs (MSP) using vendor management software (VMS) in the UK private sector market. It notes that while VMS MSP solutions were initially more popular in the public sector, the private sector appetite is now growing. There are different models for outsourcing like using just the VMS internally, outsourcing to a single "vendor-neutral" MSP, or a combined model outsourcing the VMS and MSP separately. The benefits of outsourcing include reduced costs, increased spend visibility, and ensured compliance across the organization.
