Case 01
I added three credible cases into one incorrect benefits total
In 2018, as head of strategy, I supported a proposal to invest ₹41 crore across three programmes. Each sponsor had supplied a case, and the paper presented ₹36 crore in combined annual prospective benefits. I had asked the planning team to reconcile the arithmetic and challenge individual assumptions. I had not asked whether the same operating improvement appeared in more than one sponsor's account. That omission was mine.
Finance head Dev Qevzemti and operating colleagues identified ₹9 crore of overlapping benefit attribution during a subsequent review. One sponsor argued that both programmes were necessary to make the improvement possible and should therefore retain the full amount in their own cases. That could describe a dependency, but it did not justify counting the same enterprise benefit twice. We needed to distinguish what each programme enabled from what the business could receive in total.
I withdrew the combined benefits figure and funded a ₹38 lakh review of definitions, dependencies and alternative combinations. For all three programmes together, the nonduplicative annual estimate became ₹27 crore. It remained a prospective model; the correction did not recover cash or establish an accounting adjustment. The review also made clear that changing the selection would require a different benefits assessment.
The authorised decision eventually approved two programmes with ₹28 crore proposed capital expenditure and deferred the third. I do not attach the full three-programme ₹27 crore estimate to that smaller portfolio. The accepted combination had to be evaluated on its own assumptions. Sponsors lost the simplicity of a large combined headline, and the review occupied colleagues who had expected to move straight into preparation.
My lesson was not merely to check a formula more carefully. I had allowed separately reasonable arguments to stand in for an enterprise case. Since then, I ask what operating change sits beneath a benefit and which other proposal is relying on it before I recommend adding the figures together.
