Answer: C - An unmanaged or open-ended piece of work cannot be called a project, according to PRINCE2.
Key takeaway: The principle of tailoring PRINCE2 to the project environment means (amongst other things) that certain processes and products can be simplified or expanded as necessary. It does not mean that management or plans can be dispensed with altogether. It may also come as a surprise that, despite the prevalence of meetings in modern projects, they are not always necessary.
