Responsibility Centres and Financial Performance FAQ
Why can ROI discourage a good project?
A project may exceed the company required return while reducing a division's existing ROI. Residual income reveals the added dollar value and the resulting incentive conflict.
Exam move
Start with the organisation chart only to locate decision rights. Draw a boundary around the revenue, cost and asset choices the manager actually controls, then list centrally imposed items outside that boundary. This prevents a responsibility-centre label from becoming a shortcut for controllability.
Revisit the boundary for the relevant period because a lease, staffing commitment or transfer price may be fixed this month but negotiable next year. In an answer, state the centre type and immediately explain which decisions justify that classification. Build the financial measures from their definitions before comparing performance.
For return on investment, write income over invested capital and check that both quantities use the same period and accounting basis. Decompose the percentage into sales margin and capital turnover to identify whether profitability or asset use drives the result. For residual income, subtract the capital charge from income and name the required return.
Recalculate both measures after a proposed investment so the incentive conflict is visible rather than asserted. Use a decision table with four columns: current division, proposed project, combined division and company requirement. The project can exceed the required return while falling below the current divisional ROI.
That pattern explains why a manager evaluated only on the combined percentage may reject value for the organisation. Residual income exposes the positive dollar contribution, but it does not automatically make divisions of different size comparable. Write the strength and limitation of each measure beside the result. Practise denominator discipline.
Decide whether invested capital is measured at beginning, ending or average values and apply that convention consistently. Check whether assets are recorded at gross cost or written-down amount, because older assets can mechanically raise ROI. Identify idle assets, leased resources and shared facilities before deciding what belongs in the base.
If the question is silent, state the assumption and show why a different convention could change the comparison. Pair financial outcomes with a small causal set of non-financial indicators. A maintenance deferral may improve current income while equipment reliability declines; a service cut can lift margin while retention weakens.
Choose operational measures that reveal whether present results can persist, such as defects, delivery reliability, capability or customer behaviour. Every indicator needs an owner, a time horizon and a reason it should lead later financial performance. Avoid adding measures merely to make the dashboard appear balanced. Review controllability before attaching reward or blame.
Separate an adverse outcome caused by the manager's choice from one caused by a central policy, inherited asset base or external shock. This does not mean excluding every uncontrollable item from the report. Show the full economic result, then distinguish the evaluation adjustment so senior management still sees the exposure. Explain shared responsibility when purchasing, production and investment choices interact.
Create two original cases for timed practice. In the first, compute current ROI, project ROI, combined ROI and project residual income, then write a recommendation that aligns divisional incentives with the company hurdle rate. In the second, compare two centres only after adjusting for asset age, risk and accounting policy.
Mark the work by checking the measure definition, numerical bridge, behavioural consequence and conditional recommendation separately. The six-mark worked split in this chapter is an AskSia practice allocation, not a published Monash marking scheme. Finish revision by teaching the evaluation design aloud without notes.
Begin with purpose, move to controllability, calculate on a consistent basis and end with the behaviour the measure is likely to encourage. If an answer says one measure is better, ask better for which decision and at what cost. A strong conclusion names the preferred measure or combination, the action it supports and the evidence that would cause management to revise the design.
Add a mixed-evidence drill with two divisions that have different asset ages, one centrally imposed charge and one proposed project. Decide which facts belong in economic reporting, manager evaluation or both. Recalculate after removing only the uncontrollable item and keep the adjustment transparent.
Then test long-term behaviour: if the preferred measure encourages maintenance deferral, asset underinvestment or rejection of a positive-return proposal, pair it with a forward-looking indicator. Finish by explaining the measure's purpose, the behaviour it may create and the governance response. This joins arithmetic, boundary choice and incentive design instead of treating them as separate topics.
As a last check, compare the recommended evaluation package with the manager's actual decision rights. Remove any measure the manager cannot influence, retain the economic exposure for senior reporting and explain the adjustment openly so fairness never becomes concealment.
