A 2024 geographic-expansion proposal used the number of venues as the main unit for estimating migration work. Discovery across 60 sites found 48 with two planning rooms and 12 with seven. That meant 96 rooms in the first group and 84 in the second, or 180 rooms in total. Treating each venue as one planning unit had hidden differences in availability, production use and the records that would need to be carried into the software.
The expansion team argued that a venue remained one customer and that a common migration approach should absorb the variation. Implementation colleagues agreed that some work could be shared, but they could not accept the assumption that all room-level records and arrangements would disappear into one undifferentiated unit. I supported revising the commitment before using the model to enter another geography. The customer count was still useful for some commercial purposes; it was insufficient for this estimate of work.
We deferred the ₹3.6 crore geographic-expansion proposal and separately approved ₹1.1 crore for migration redesign. The redesign remains a programme to complete, not a reported implementation success. I did not subtract the two figures and call the result money saved. They were different proposals with different purposes, and the decision changed their sequence rather than proving a financial benefit.
The trade-off was a later market entry and a less attractive near-term growth account. I accepted that consequence because the existing assumption would have carried an understated commitment into the next proposal. Product and implementation teams retained responsibility for the actual design, and customers retained authority over room availability and production arrangements. Our software could organise planning records; it did not certify that a venue or schedule was operationally safe.
The case changed the way I ask for a unit in an expansion model. A customer, a site and a room can all be legitimate counts, but they serve different decisions. The model should explain why its chosen unit corresponds to the work being funded. When that relationship changes, the strategic account needs to change with it rather than defend the original simplicity.
