Evolution of IT Management

IT Service Management • It is a discipline for managing large-scale IT systems • Philosophically centered on the customer's perspective of IT's contribution to the business • Stands in deliberate contrast to technology-centered approaches to IT management • Has ties and common interests with the process improvement movement (E.g. TQM, Six Sigma, CMM etc.) • “IT thinking about the delivery of IT to the business” and not • “IT thinking about the 'information' needs of the business”

IT Service Management (contd) • Contributing frameworks: – Control Objectives for Information Technology (COBIT) – Microsoft Operations Framework (MOF) – Enterprise Computing Institute – Information Technology Infrastructure Library (ITIL)

Overview of ITIL • ITIL is a framework of best practice approaches intended to facilitate the delivery of high quality IT services • It is published in a series of books (hence the term Library), each of which covers a core area within IT Management • The names ITIL and IT Infrastructure Library are Registered Trade Marks of the United Kingdom's Office of Government Commerce (OGC)

Availability Management • Availability •Reliability •Maintainability •Serviceability

Availability Management • Percentage availability (uptime) • Downtime duration • Downtime frequency

• Business must have clearly defined  availability objectives •SLM must have been clearly set up to  formalize agreements

Capacity Management • Performance Management: Measuring,  monitoring and tuning the performance of IT  infrastructure components. • Application Sizing: Determining the  hardware or network capacity needed to  support new or modified services. • Capacity Planning: Developing capacity  plan, based on CDB.

Capacity Management • Predictability of customer demand • Technology • Cost

• Accurate business forecast &  expectations. • Understanding of IT strategy and  planning.

Continuity Management • Disaster: An event that affects a  service or system such that significant  effort is required to restore the original  performance level.

Continuity Management • No of identified shortcomings of the  recovery plan • Revenue lost further to disaster

• Support and communication throughout  the organization • Dedicated training for anyone involved  in the process

Benefits of ITIL • Benefits to the customer/user: – Provision of IT services becomes customer­ focused – Agreements about service quality improves  relationship – Services are described better, in customer  language – Quality, Availability, Reliability and Cost of  services are managed better

Benefits of ITIL (contd) • Benefits to the IT organization:

IT organization develops clear structure More focus on corporate objectives More control of infrastructure Easier to manage changes Coherent framework for internal and external  (supplier) communication – Process structure provides for effective  outsourcing of elements of IT service – – – – –

Some Testimonials • Procter & Gamble – Started using ITIL in 1999 and has realized a 6% to 8% cut in operating costs. – Another ITIL project has reduced help desk calls by 10%. In four years, the company reported overall – Savings of about $500 million.

Testimonials (contd) • Caterpillar – Embarked on a series of ITIL projects in 2000. – After applying ITIL principles, the rate of achieving the target response time for incident management on Web-related services jumped from 60% to more than 90%.

Testimonials (contd) • Nationwide Insurance – Implementing key ITIL processes in 2001 led to a 40% reduction of its systems outages. – The company achieved a $4.3 million ROI over the next three years

Reasons for failure of ITIL implementation • Lack of management commitment • Spending too much time on complicated process diagrams • Not creating work instructions • Not assigning process owners • Being too ambitious • Concentrating too much on performance • Not reviewing the entire ITIL framework
