ITIL4F ITIL Service Value System Practice Question
A project team is developing a new mobile banking app. They decide to reuse an existing authentication module and focus on adding new features. Which ITIL 4 guiding principle is being applied?
⚠ Common exam trap
A common mix-up: candidates confuse 'Start where you are' with 'Focus on value' because both involve efficiency, but the key distinction is that 'Start where you are' specifically addresses leveraging existing assets, while 'Focus on value' is about ensuring all activities deliver measurable outcomes to stakeholders.

Correct answer & explanation
✓
Start where you are
The team is reusing an existing authentication module rather than building a new one from scratch. This directly applies the 'Start where you are' guiding principle, which recommends leveraging existing services, processes, and capabilities to avoid unnecessary rework and reduce risk. By starting with what already works, the team can focus effort on new features, maximizing efficiency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Collaborate and promote visibility
Why it's wrong here
The 'Collaborate and promote visibility' guiding principle emphasizes working across organizational boundaries and ensuring that information, activities, and progress are transparent to all relevant stakeholders. While crucial for project success, this principle primarily addresses communication and teamwork dynamics, fostering shared understanding and mutual respect. It does not, however, directly advocate for the strategic identification and incorporation of pre-existing components or processes into a new development effort, which is distinct from promoting open communication.
- ✗
Progress iteratively with feedback
Why it's wrong here
The 'Progress iteratively with feedback' guiding principle advocates for organizing work into smaller, manageable iterations, allowing for frequent feedback loops and adjustments throughout the development lifecycle. Its core focus is on continuous improvement and adaptability through incremental delivery, enabling learning and course correction. This principle guides how work is done and refined over time, rather than the initial assessment and strategic incorporation of existing organizational resources or solutions to accelerate a new project.
- ✗
Focus on value
Why it's wrong here
The 'Focus on value' guiding principle directs all activities towards delivering outcomes that contribute to the value perceived by stakeholders. While reusing existing components might indirectly contribute to value by reducing costs, accelerating time-to-market, or improving quality, this principle's primary emphasis is on understanding and defining value from the consumer's perspective. It ensures all efforts align with its realization, rather than prescribing the specific approach of leveraging pre-existing assets as the core tenet.
- ✓
Start where you are
Why this is correct
The 'Start where you are' guiding principle mandates that organizations assess their current state and leverage existing services, processes, tools, and people whenever possible, rather than starting from scratch. For a new mobile banking app, this means identifying and reusing existing components, APIs, security protocols, or even development methodologies already present within the organization. This approach avoids unnecessary duplication of effort, accelerates development, and leverages prior investments, directly promoting the strategic reuse of assets.
