Introduction to Continuous Service Improvement (CSI) according to ITIL for the continuous improvement of service management

In today's digital age, where organisations are constantly growing and evolving, it is crucial for the efficient delivery of IT services to continuously improve. Continual Service Improvement (CSI) is an important part of the ITIL v3 framework and offers companies the opportunity to continually optimise their IT services. In addition to: Service Operation, Service Transition, Service Strategy and Service Design, Continual Service Improvement rounds off professional IT Service Management in accordance to ITIL v3. In this blog article, we will introduce CSI, explain its purpose, define basic terms, explain processes and activities used in CSI, describe the different roles and finally illustrate the benefits of CSI for your Service Desk in ITIL Service.

Continual Service Improvement is one of the five core areas of the IT Infrastructure Library (ITIL) v3 framework. It aims to continuously improve the performance and efficiency of IT services. Through an iterative and action-based approach, CSI enables companies to identify weaknesses, optimise their services and increase customer benefits.

Objectives of Continuous Service Improvement (CSI) according to ITIL

The main aim of continuous service improvement is to establish a proactive culture of improvement. It encourages companies to constantly look for ways to optimise the quality of their IT services. CSI aims to identify, analyse and eliminate weaknesses and introduce proven methods to continuously monitor and improve the service.

Basic concepts of CSI

To make it easier to understand CSI, it is important to define basic terms:


Improvement is the continuous service improvement of IT services and service management processes. It involves identifying areas that can be improved, defining goals and measures to achieve these goals, and regularly reviewing and monitoring progress. The aim of improvement is to increase efficiency, quality and customer satisfaction in IT service management.

Service Level Agreement (SLA)

An SLA is an agreement between the service provider and the customer in which the objectives, performance and expectations for the service are set out.

Key Performance Indicators (KPIs)

KPIs are used to measure the success of the service and provide information on service quality and customer satisfaction.

Service Improvement Plan (SIP)

A SIP is a documented concept that describes the identification, analysis and resolution of problems as well as the implementation of improvement measures.

EcholoN Blog - ITIL CSI - the seven-step improvement process

Sieben-Schritte-Verbesserungsprozess (7-Step Improvement Process)

The seven-step improvement process is a process model that helps organisations to achieve continuous improvements in their IT services. This process is an essential part of IT service management and consists of seven consecutive steps. Each step is designed to identify problems, propose changes, implement them and review their impact.

  • The first step of the process is to identify opportunities for improvement. This can be done by monitoring key performance indicators, collecting feedback from customers or employees or conducting audits. The aim is to identify areas where there is room for change.
  • In the second step, the objectives for the change are defined. The aim here is to define clear and measurable goals to be achieved. These goals should be aligned with the company's business objectives and be realistic.
  • In the third step, solutions are developed to implement the identified improvements. This can include, for example, implementing new technologies, adapting processes or training employees. Here it is important to evaluate the various solution options and select the most suitable one.
  • The fourth step is to implement the solutions. This involves conducting tests to ensure that the changes work, as well as training employees to ensure that they understand and can use the new processes or technologies.
  • Implementation is followed by the fifth step, monitoring and measurement. This is where the relevant key performance indicators are continuously monitored to ensure that the desired goals are being achieved. If necessary, adjustments can be made to achieve the desired result.
  • The sixth step involves an evaluation. It is checked whether the implemented measures have actually achieved the desired results and whether further changes are possible. Feedback from customers and employees can help to carry out this evaluation.
  • b If these are successful, they become part of regular operations and are integrated into the IT service management processes. If further changes are required, the process starts again.

The process model of the seven-step improvement process in the CSI offers companies a structured method for achieving continuous improvements in their IT services. It provides a systematic approach to identifying problem areas, developing and implementing solutions and monitoring the results. Through this process, companies can increase their service quality and reduce costs at the same time.
