Continual Service Improvement is the final stage in the ITIL lifecycle. This was covered in online ITIL training. During this stage, all services within the IT service provider are reviewed in order to identify areas that need improvement. ITIL online courses discuss how continuous improvement is applied to all stages of the ITIL lifecycle: Service Strategy and Design, Service Transition, Service Operation, and Service Transition. These stages are fed by CSI, and the information or data that comes from them also feed into the CSI process. CSI is essential to ensure that all services continue to add value to the business as well as its customers.
The continuous service improvement (CSI), stage focuses on service improvements that support business processes. CSI follows a seven-step plan that is crucial for CSI and other stages in the ITIL lifecycle.
Seven Steps to Continuous Improvement
This figure shows how the seven-step continuous improvement process aligns with the PDCA cycle (and DIKW hierarchy). Let’s review the definitions for the PDCA cycle as well as the DIKW hierarchy. The PDCA cycle shows the continuous service improvement cycle that moves through the following stages: Plan, Do-Check-Act. The DIKW hierarchy shows how data moves from unintelligible to information to knowledge and wisdom.
Step 1: Identify the strategy to improve.
It is important to understand the need for continuous improvement before a plan can be implemented. In the initial phase of ITIL service cycle, i.e. in service strategy and service development. This information is gathered through a deep understanding of the business objectives and areas that could benefit from continuous improvement. It also examines the effectiveness of the continuous improvements plan. These data are then fed into the continuous improvements plan cycle.
Step 2: Define what will measure the Continuous Improvement Process
It would be simple to identify which areas to measure by taking into account the new service level requirement and available funds. The service design stage identifies IT capabilities and implements them via service transition. To identify opportunities for continuous improvement, a gap analysis takes place during this stage. If CSI determines that the available resources and tools are not sufficient or the cost is prohibitive to deliver the desired data then the measure in the earlier step of the continuous improvements plan must be re-evaluated.
Step 3: Collect the data
The next step in the plan is to gather data according to the service operation’s goals and objectives. Monitoring is necessary to ensure that both raw and quantitative data are collected. Data quality is crucial and can be collected by manual or automated means. To collect high quality data for continuous improvement, the data collection process must be reliable and repeatable.
Step 4: Process the data
It is crucial to present the data to the audience in the format required once it has been collected. The key success factors and ITIL KPI play an important role in processing the data. It is easy to process and transform raw data into information by organizing it according to its operation and categories.
Step 5: Analyze and interpret the data
The next step in the continuous improvement plan is to analyze the data that has been converted into information. This will identify gaps and determine the impact on business. All relevant external and internal factors that directly or indirectly affect the information are taken into account.
