ITIL4-CDS Create, Deliver and Support Practice Question
When implementing a new service, which approach best aligns with the CDS principle of 'Keep it simple and practical'?
⚠ Common exam trap
Candidates often select options that involve comprehensive planning or extensive documentation, incorrectly assuming that 'best practice' means building a perfect, feature-complete service before the initial release.

Correct answer & explanation
✓
Deliver a Minimum Viable Service (MVS) that addresses the primary business goal, then iterate.
The 'Keep it simple and practical' principle encourages avoiding over-complication. In service implementation, this means starting with the minimum viable functionality and iteratively improving it. This reduces complexity, lowers the initial barrier to entry, and allows the team to learn from real-world feedback rather than spending months building features that might not be necessary or might not work as intended in the production environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Document every possible edge case before writing a single line of code.
Why it's wrong here
Documenting every edge case is an example of over-engineering and 'analysis paralysis.' This approach is complex, slow, and often based on assumptions that change once the service is in use. It contradicts the principle of keeping things simple, as it delays value delivery for unnecessary, theoretical documentation.
- ✗
Build a comprehensive, feature-rich service that includes every user requirement identified.
Why it's wrong here
Attempting to build everything at once leads to high complexity, long lead times, and potential project failure. It is the opposite of keeping things simple. By prioritizing all requirements, the team risks delivering a bloated service that is difficult to support and doesn't focus on the most critical value.
- ✓
Deliver a Minimum Viable Service (MVS) that addresses the primary business goal, then iterate.
Why this is correct
Delivering an MVS is the epitome of keeping it simple and practical. By focusing only on the primary goal, the team minimizes risk and complexity. This allows for rapid delivery and constant refinement based on actual usage, which is far more efficient than planning for every theoretical requirement beforehand.
- ✗
Adopt a complex microservices architecture immediately to ensure the system is future-proof.
Why it's wrong here
Introducing complex architecture prematurely is an unnecessary complication. Unless the business requirements explicitly demand high-scale microservices, it is better to start simple and evolve as needs grow. Over-engineering architecture early on leads to significant maintenance burdens and operational complexity that is often not justified by the initial business value.
