Last month I started a series of preparation notes as I study for my IT Infrastructure Library (ITIL®) Foundation certification:
- Part 1 was an overview/introduction.
- Part 2 covered service strategy.
- Part 3 covered service design.
- Part 4 looked at service transition.
- Part 5 was concerned with service operation.
This post continues by looking at the topic of the fifth and final stage in the ITIL service lifecycle: continual service improvement (CSI).
Continual Service Improvement
Generally, the performance of a service can be improved upon – that’s where CSI comes in:
“Focuses on increasing the efficiency, maximising the effectiveness and optimising the cost of services and the underlying ITSM processes.”
- Japanese term that means continuous improvement (literally, “change good”). Small steps.
- IT Governance:
- Defining expectations, assign power, verify performance. Has everything been done that should be.
- Enterprise (business); Corporate (regulatory); IT (management, rules, regulations and framework of IT department).
- CSI register:
- Database/record of improvement opportunities. Part of the Service Knowledge Management System (SKMS).
“If you can’t describe what you’re doing as a process, you don’t know what you’re doing” [William Edwards Deming]
Seven Step Improvement Process:
- Identify the strategy for improvement.
- Define what you will measure. (Because you can’t control what you can’t measure!)
- Gather the data.
- Process the data. Turn it into information.
- Analyse the information and data. Identify actions.
- Present and use the information. Changes to be made.
- Implement improvement.
Deming cycle (actually it’s not Deming’s work – but he’s often credited):
- Check. On progress.
- Act. Maybe need another iteration…
The CSI Approach:
- What is the vision? Business goals, etc.
- Where are we now? Establish baselines.
- Where do we want to be? Set target (measurable).
- How do we get there? Process improvement – gap analysis, defined goals.
- Did we get there? Measure and check metrics.
- How do we keep up the momentum? Look to go around again…
That’s the end of this series – by the time you read this, I’ll be on my way to the exam testing centre…
40 questions, multiple choice, 60 minutes. £168.
Fingers crossed, creating these notes will help me – and I hope they help you out too.
