Book Description
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 provides governance, management, integration, assurance and coordination at strategic, tactical and operational levels. It creates an ecosystem where all parties:
-
- Understand their role, responsibilities and context
- Are empowered to deliver within clear boundaries
- Are accountable for the outcomes they enable
This updated edition of SIAM Foundation provides a comprehensive introduction to SIAM and is the official guide for the EXIN SIAM(TM) Foundation certification. This publication helps candidates prepare for the Foundation exam and introduces SIAM concepts, roadmap stages, structures, roles, practices and cultural considerations for successful adoption. It will appeal to:
-
- Anyone seeking an introduction to SIAM and the SIAM(TM) Foundation certification
- Customer organizations and their staff managing multi-provider ecosystems
- Service integrators and their teams establishing end-to-end accountability
- Internal and external service providers wanting to work effectively in SIAM
- Consultants in service management supporting SIAM design and adoption
“SIAM Foundation brings together the real-world experience of practitioners from across the SIAM community to provide a clear, practical introduction to managing services in a multi-provider ecosystem. It will help you focus on outcomes, deliver maximum value, and manage end-to-end services across complex supply networks, a necessity in today’s digital, cloud-enabled environments. SIAM Foundation sets out the essential definitions, roles, structures and practices, and explores the common challenges you’ll face when adopting SIAM, making it valuable for practitioners at every level as well as those studying for the globally recognised SIAM Foundation certification.”
