Our 2024 procurement interface proposed forty-two spare-part substitutions based on catalogue descriptions and a supplier's equivalence groups. The suggestion was useful for finding candidates, but it appeared in the same place a planner would normally see an approved replacement. Engineering review supported twenty-one pairings, rejected fifteen as incompatible for the stated use and left six unresolved. Treating the original forty-two as interchangeable would have turned a search aid into a professional conclusion.
Procurement colleagues wanted to retain the broad list because it improved apparent availability and could reduce waiting for a named part. That was a real operating concern, not simply resistance to control. Rohan's team wanted the conditions of each substitution assessed before it entered the usable replacement list. I supported a ₹41 lakh systems and review programme, alongside a separate ₹18 lakh inventory-carry provision associated with retaining appropriate stock while alternatives were examined. Neither amount was presented as savings from parts we had not yet approved.
The system separated suggested, engineering-confirmed, incompatible and unresolved relationships. The twenty-one confirmed pairings retained the relevant equipment and use conditions rather than becoming universal declarations about two part numbers. The fifteen incompatible suggestions were excluded for the examined use, and the six unresolved ones could not be chosen as approved substitutes. Procurement still had access to the candidate information for further work; the correction did not require hiding the existence of alternatives or treating a supplier's suggestion as worthless.
The operating compromise was to accept a less impressive availability display while preserving a route to assess useful candidates. I wanted the interface to show which authority a relationship carried. A search result, a supplier grouping and an engineering decision can all be legitimate records, but they should not acquire the same meaning simply because the screen has room for one status. This invented case asserts no actual equipment damage, product recall, manufacturer approval or universal compatibility. It demonstrates a CIO decision about how professional authority is represented, with the cost of retaining uncertainty visible beside the benefit of a convenient catalogue. The programme was strongest where it preserved the suggestion as a suggestion until the appropriate judgement changed its status.
