ITIL Service Strategy

”People do not want quarter-inch drills. They want quarter-inch holes.”

– Professor Emeritus Theodore Levitt, Harvard Business School

  • Customers do not buy products but buy a satisfaction of particular needs.
  • Understanding customer needs in terms of:
    • Why,
    • What and
    • Customers of customer.
  • Aligned to the Business culture.
  • Based on the clear understanding of the existing competition.

ITIL Service Strategy – Key Concepts

Value creation through Service Strategy.

1. Resources & capabilities – Turned into products & services of value to the business.

  • Resources – Direct inputs for the production.
  • Management, organization, people and knowledge – used to transform resources.
  • Capabilities – ability to coordinate, control and deploy resources.
  • Capabilities without adequate resources cannot produce value.

2. Distinct capabilities are developed to retain customers with value propositions that are hard  for competitors to  duplicate.

What is the value for the customers ? Create Value

  • Marketing Mindset – Help to understand the value of a service to the customer in terms of their:
  • Perceptions,
  • Preferences.

Questions to ask:

  • What is our business ?

  • Who is our customer ?

  • What does the customer value?

  • Who depends on our services?

  • How do they use our services ?

  • Why are they valuable to them ?


ITIL Service Strategy – Four P’s

  • Perspective: The distinctive vision and direction.
  • Position: The basis on which the provider will compete.
  • Plan: How the provider will achieve their vision.
  • Pattern: The fundamental way of doing things – distinctive patterns in decisions and actions over time.

ITIL Service Strategy – Service & Warranty

ITIL Service Strategy – Service & Warranty

Service Utility

  • Add activities, objects, or tasks that the customer wants.
  • Relax or remove constraints on performance.

Service Warranty

  • What the customer wants is available when needed and in sufficient capacity or magnitude.
  • What the customer wants is delivered with security and continuity.

ITIL Service Strategy – Service Provider Types

  1. Type I – Internal Service Provider
    • Business unit functions serving solely for one business unit.
    • Eg: TIS having its own IT arm
  2. Type II – Shared Service Provider
    • Serving multiple BU in same organization but are NOT at the company’s core competitive edge.
    • Eg: WT IMG serving all business of WT
  3. Type III – External Service Provider
    • Supporting multiple external customers
    • Eg: TIS serving multiple external client

ITIL Service Strategy – Service Provisioning Models

  • Managed Service: The business unit that requires the service fully funds for all its IT services.
  • Shared Service: Provisioning of multiple services to multiple Business units through shared infrastructure and resources.
  • Utility: Services are provided based on customer business needs.

ITIL Service Strategy – Service Portfolio

1. Service portfolio is the collection of all the services committed to the customers.

  • Present contractual commitments
  • New service development
  • Ongoing service improvement programs

Note: It also includes third part service programs which are integral part of customer service offerings

2. Service Portfolio represents the ability  and the readiness of the service provider to serve the customer in the market space.

3. Three Phases

  • Service catalog – currently available
  • Service pipeline – what is cooking
  • Retired services – no longer available

ITIL Service Strategy – Service Catalog

  • Subset of service portfolio which is visible to customers.
  • Contains services that are currently being offered plus the services which are approved and ready to offer.
  • The virtual projection of service providers current capabilities.

Two Kinds:

  • Business Service catalog – Customer view of the service catalog.
  • Technical Service catalog – underpins the Business service catalog not visible to customers.

ITIL Service Strategy – Purpose

  • Sits at the core of ITIL V3 life cycle.
  • Sets out guidance to service providers and customers to thrive in the long term  by clear building of Service strategy.
