Book excerpt: Note: This book is available in several languages: French, English. The eSourcing Capability Model for Client Organizations (eSCM-CL) is the best practices model that enables client organizations to appraise and improve their capability to foster the development of more effective relationships and to better manage these relationships. This title helps readers successfully implement a full range of client-organization tasks, ranging from developing the organization's sourcing strategy, planning for sourcing and service provider selection, initiating an agreement with service providers, managing service delivery, and completing the agreement. The eSCM-CL has been designed to complement existing quality models and sourcing frameworks so that clients can capitalize on their previous improvement efforts and meet mandated requirements. ITIL V3 suggests that ITIL be supplemented with eSCM when service management is performed in the context of a sourcing arrangement. Developed by The IT Services Qualification Center (ITSqc) and endorsed by a number of organizations including IAOP® (International Association of Outsourcing Professionals), this title represents a major step forward for professionals looking to implement Best Practice within the Industry.
