Exam PRINCE2-Practitioner topic 21 question 18 discussion

C. No, because benefit tolerances should only be set at the project level within the business case ? In PRINCE2, benefit tolerances are set in the business case to define the expected benefits of the project and the range of acceptable variation. These tolerances are a project-level control measure, and are not typically established within individual work packages.

A In this case, the project manager is authorizing the work package for the ‘marketed courses’, which are expected to generate sales. By setting a benefits tolerance within this work package, the project manager is defining the acceptable range of sales (benefits) that this work package should generate. This is an appropriate action because it helps to manage expectations and provides a clear target for the ‘marketed courses’ to achieve. It also allows for effective management by exception, as any deviation outside this tolerance would need to be escalated for decision-making
