In a project using PRINCE2, the project board is reviewing the End Stage Report. They notice that the actual costs are significantly lower than planned, but the scope is complete. What should the project board do?
Trap 1: Request an exception plan to reallocate the surplus
An exception plan is only triggered when a stage or project is forecast to exceed its tolerances; underspend with complete scope breaches nothing. It is tempting because surplus feels like a deviation needing formal handling, but PRINCE2 exception mechanisms address forecast breaches, not favourable variances.
Trap 2: Immediately authorize the next stage as the project is under budget
The board should first understand the reasons for the under-run before authorizing.
Trap 3: Ask the project manager to revise the project plan to increase costs
Revising the plan to spend surplus contradicts PRINCE2's principle of continued business justification; underspend with complete scope needs no corrective plan. It is tempting because budgets are usually the problem, but here the board should simply authorise the next stage, since tolerances are not breached.
- A
Request an exception plan to reallocate the surplus
Why it fails: An exception plan is only triggered when a stage or project is forecast to exceed its tolerances; underspend with complete scope breaches nothing. It is tempting because surplus feels like a deviation needing formal handling, but PRINCE2 exception mechanisms address forecast breaches, not favourable variances.
- B
Immediately authorize the next stage as the project is under budget
Why it fails: The board should first understand the reasons for the under-run before authorizing.
- C
Ask the project manager to revise the project plan to increase costs
Why it fails: Revising the plan to spend surplus contradicts PRINCE2's principle of continued business justification; underspend with complete scope needs no corrective plan. It is tempting because budgets are usually the problem, but here the board should simply authorise the next stage, since tolerances are not breached.
- D
Review the End Stage Report and decide whether to authorize the next stage
PRINCE2 stage boundaries require the project board to review the End Stage Report and authorise the next stage. Underspend with complete scope is favourable but does not remove that governance checkpoint; the board still decides whether to proceed.
