PRINCE2F Project Initiation and Stages Practice Question
A project is in the Initiation Stage. The project manager is creating the Project Plan and needs to define the project's products and activities. Which PRINCE2 principle should guide the level of detail included in the plan?
⚠ Common exam trap
The trap here is selecting a principle that seems relevant to planning, such as 'Focus on products', when the question specifically asks about the level of detail, which is governed by tailoring.

Correct answer & explanation
✓
Tailor to suit the project environment
The PRINCE2 principle 'Tailor to suit the project environment' guides the level of detail in plans. It requires adapting the method to the project's specific needs, so the Project Plan's detail should reflect the project's size, complexity, and risk.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manage by exception
Why it's wrong here
Manage by exception is about defining tolerances and delegating authority, not about the level of detail in plans. It ensures the Project Board only gets involved when tolerances are threatened. It does not directly guide how detailed the Project Plan should be; that is influenced by the principle of tailoring.
- ✓
Tailor to suit the project environment
Why this is correct
The principle 'Tailor to suit the project environment' means PRINCE2 should be adapted to the project's size, complexity, and risk. The level of detail in the Project Plan should be tailored accordingly. For a small, low-risk project, a less detailed plan may suffice, while a large, complex project requires more detail.
- ✗
Focus on products
Why it's wrong here
Focus on products means defining and delivering products that meet requirements. It influences what is planned but not the level of detail. The detail of the plan is a tailoring decision, not a product-focus decision. The principle of tailoring is the correct guide for how much detail to include.
- ✗
Learn from experience
Why it's wrong here
Learn from experience involves using lessons from previous projects to inform current work. While lessons may influence planning, they do not dictate the level of detail. The principle of tailoring is directly concerned with adjusting the method's application, including plan detail, to the project's needs.
