Service Level Mgmt Enterprise Networks

SERVICE LEVEL MANAGEMENT FOR ENTERPRISE NETWORKS
by Lundy Lewis

“After Service Level Agreements (SLA) are made between IT providers and consumers,
expectations and services to be rendered vary widely and standardization is often
fragmented. This first-of-its-kind, comprehensive examination of IT Service Level
Management provides a much-needed framework for implementing and evaluating Service
Level Agreements and helps you avoid common pitfalls.

“Service Level Management of Enterprise Networks not only delivers new methodology and
techniques to improve SLAs, through discussion of SLM processes and architecture, but
also serves as a baseline against which to measure existing and future SLM programs. With
a general knowledge of business processes, information management and technology, and
networking equipment, IT professionals and clients will learn more about the challenging
issues of SLM and the viable, real-world solutions available.

“ Examining research challenges, using real-world case studies, and discussing current tools
and applications, this up-to-the-minute book is essential for suppliers and consumers of IT in
large organizations and suppliers serving multiple clients, vendors building tools to support
SLM, and university professors interested in the application of SLAs.”
