Service Design-Overview

We will focus on the purpose, objective, scope, and value of service design.


The purpose of service design includes the following:

  • To design IT services in alignment with the governing policies, IT practices, and processes

  • To understand the service provider’s strategy

  • To make sure the service delivery is of high quality

  • To ensure cost-effective service provision and customer satisfaction

Now let us understand the objectives of service design.


Following are the objectives of service design:

  • Service design aims at designing IT services efficiently and effectively to avoid major improvements.

  • The changing trends in business are identified and this leads to opportunities for the improvement of services and solutions.

  • Continual Service Improvement or CSI is included in all service design activities to ensure their effectiveness.

Let us now focus on the scope of service design.


The scope of service design is to interpret and design the following:

  • New, existing or modified business requirements

  • Management information systems and tools

  • Technology, management and architecture systems

  • Measurement methods and metrics

  • All processes essential for effective service design

Now let us discuss the value that service design brings to a business. 


Service design offers the following benefits:

  • Lower Total Cost of Ownership (TCO) of services

  • Improved quality of service delivery

  • Improved consistency of the service, as services are designed within the corporate strategy, architectures, and constraints

  • A simpler implementation of new or modified services

  • Improved services being aligned with the needs of the business

  • Improved effectiveness of performance with incorporation and recognition of capacity, financial availability and IT service continuity plans
