Which role is responsible for ensuring that the project continues to have business justification?
The Executive is responsible for business justification.
Why this answer
The Executive is the single point of accountability for the project and is responsible for ensuring that the project continues to have business justification throughout its lifecycle. This includes approving the business case, monitoring its validity, and making the final decision to continue, change, or close the project based on ongoing justification.
Exam trap
The trap here is that candidates often confuse the Project Manager's responsibility for developing and maintaining the business case with the Executive's accountability for approving and ensuring its ongoing validity.
How to eliminate wrong answers
Option A is wrong because the Senior Supplier represents the interests of those providing the project's products and resources, but does not own the business case or have authority to decide on continued business justification. Option B is wrong because the Senior User represents the interests of those who will use the project's outputs and specifies the benefits, but does not hold the ultimate accountability for business justification. Option D is wrong because the Project Manager is responsible for day-to-day management and producing the business case, but the authority to approve and ensure ongoing justification rests with the Executive.
