This scenario is fundamentally about learning from post-project review , updating future assumptions, revising asset management planning, and ensuring the organization’s financial records and depreciation assumptions reflect the new evidence. The IAM Anatomy of Asset Management Version 4 states that asset costing and valuation include the organization’s end-to-end process for quantifying the financial value of assets in accordance with accounting standards , and specifically includes depreciation as the method used to establish the residual or remaining lives of assets and the accuracy of depreciation calculations.
In your scenario, the asset was originally given a 50-year depreciation life , but evidence from the post-project review now indicates the useful life is more likely 30 years . Under IAM-aligned practice, that new information should absolutely be fed back into future modelling, project design and build , and the Asset Management Plan should be updated. In addition, because the revised life affects asset value, remaining life, and depreciation treatment, the financial function must be informed so that any required accounting adjustments can be assessed. That last step is an inference from IAM’s explicit treatment of asset valuation, depreciation, and alignment with the financial balance sheet .
Why the other options are incorrect:
A is wrong because assigning blame is not the primary asset management response; the priority is learning, updating plans, and correcting financial implications.
B is wrong because reducing maintenance simply to recover cost is not IAM logic and could destroy value.
D may become relevant later, but the question asks what to do with the information now; the immediate cross-functional requirement is also to notify Finance .
E is clearly wrong because the information materially affects planning assumptions and potentially financial reporting.
Therefore, the best IAM-aligned answer is C .
