Service integration and management (SIAM) is a management methodology for creating value in an ecosystem where multiple service providers contribute to end-to-end services. It has evolved as organizations moved from single-supplier outsourcing to multi-sourced, increasingly digital, cloud-enabled delivery, where objectives, contracts, data and targets can become misaligned.SIAM enables cross-functional, cross-process and cross-provider integration by establishing a service integrator capability that coordinates governance, management, assurance and continual improvement. It creates an ecosystem where all parties understand their role, responsibilities and context, are empowered to deliver within boundaries, and are accountable for the outcomes they enable.SIAM Professional, third edition, forms part of the refreshed Scopism SIAM Body of Knowledge and is the official guide for the EXIN SIAM Professional certification. This book supports candidates preparing for the certification and focuses on applying SIAM in practice, building on the concepts introduced in SIAM Foundation. The book will appeal to:Practitioners who want to deepen their SIAM capability and achieve the SIAM Professional certificationCustomer organizations seeking practical guidance for operating and improving multi-provider servicesService integrators and their teams delivering integrated, outcome-focused governanceInternal and external service providers wanting clarity on how to collaborate in a SIAM ecosystemConsultants in service management and related frameworks looking to extend their expertise Over the last decade we ve seen SIAM gain relevance across increasingly complex provider landscapes and supply chain management challenges. The updated SIAM Body of Knowledge offers a renewed look at the core concepts of multi-provider management but extends the breadth and depth of this with additional and flexible Compendiums. More than 75 experts from around the world offered their knowledge, experience and thoughts to provide content that is applicable and suitable for any type of organization.As part of the Body of Knowledge, SIAM Professional does exactly that; it expands on the foundational concepts, offering advice and examples that transform SIAM theory and common sense to practically applicable guidance. We hope practitioners can find knowledge and inspiration from this publication to improve their organizational operating model. Simon Dorst & Michelle Major-Goldsmith
