"Those who use the service on a day-to-day basis. Users are distinct from customers, as some customers do not use the IT service directly."
"Third parties responsible for supplying goods or services that are required to deliver IT services. Examples of suppliers include commodity hardware and software vendors, network and telecom providers, and outsourcing organisations."

Change organisational culture
Deliver value for customers
Focus on business strategy and customer need
Management of money, risk, knowledge, resources, capabilities
Effective, efficient, and economical
Improve interaction and relationships with customers
"The complimentary set of ITIL publications provides guidance to specific industry sectors, organisation types, operating models, and technology architectures"
ITSM is complicated because...
intangible nature of output
demand tightly coupled with customer's assets
high level of contact with customers
perishable nature of output
Outcome-based definition of service
customer outcome more important than requirements
"customers seek outcomes, but do not wish to have accountability or ownership of all the associated costs and risks."
Four Perspectives of ITSM
- People Perspective
- Product/Technology Perspective
- Process Perspective
"Automation is considered to improve the utility and warranty of services."
- adjust to demand
- across timezones
- basis for measuring and improving services
- computing power
- codified knowledge
