Let’s now look at the continual improvement model in ITIL 4.
The continual improvement model provides a structured approach for identifying and managing improvements.
It helps organisations understand where they are now, where they want to be, and how to get there.
The model consists of several steps that guide improvement activities.
These steps help ensure that improvements are planned, measured, and aligned with organisational objectives.
The continual improvement model can be applied to services, practices, and the organisation as a whole.
Using the model helps organisations make consistent and effective improvements.
Understanding the continual improvement model is important for applying continual improvement in practice.
2. How this applies to TakeCars (car-rental marketplace)
This section explains how TakeCars can turn “we should fix this” into a repeatable improvement discipline instead of reactive firefighting.
a) The continual improvement model = structured learning loop
In TakeCars terms, the model forces clarity:
- Where are we now?
- High dispute rate on deposits
- Slow supplier confirmations
- Where do we want to be?
- Fewer disputes
- Faster confirmations
- How do we get there?
- Policy refinement
- Automation
- Supplier segmentation
Without this structure, improvements remain opinion-driven.
b) Preventing “random optimisation”
Marketplaces often:
- Fix what is loudest
- Optimise what feels urgent
- Chase symptoms instead of causes
The ITIL model forces:
- Baselines
- Targets
- Measurable outcomes
For TakeCars, this means:
- Measuring dispute resolution time before changing rules
- Tracking confirmation speed before automating
- Comparing cohorts before rolling out changes
c) Making improvement scalable
As TakeCars grows:
- Founders cannot decide every improvement
- Support cannot invent fixes ad hoc
The continual improvement model:
- Creates shared language
- Enables delegation
- Preserves consistency
This is how improvement survives growth.
3. Key ideas to read right before the exam (high-yield)
The continual improvement model is often tested as a “what is its purpose?” question.
Core understanding
The continual improvement model:
- Provides a structured approach
- Supports planning and managing improvements
- Helps move from current state to desired state
If an answer:
- Mentions structure and alignment → strong
- Mentions ad-hoc improvement → weak
Exam trap to avoid
Wrong answers often:
- Confuse the model with the guiding principles
- Treat it as a single step
- Limit it to IT only
Correct answers:
- Emphasise structured improvement
- Apply broadly
- Align with objectives
