Case 01
Owning a retry design that created seventeen duplicate purchase orders
In 2018 I approved a purchasing integration that retried a request when the earlier response had not arrived. The receiving process treated the repeated submission as a new order. Seventeen duplicate purchase orders, carrying ₹34 lakh combined face value, were created before the problem was isolated. They were cancelled before goods were supplied against them. The enterprise incurred ₹13 lakh to repair the integration and reconcile the affected process.
My approval had accepted technical persistence without sufficiently examining commercial intent. A missing response did not establish that the first request had failed. Equally, two requests with similar contents could sometimes represent two legitimate purchases. The design needed a way to preserve the identity and disposition of the intended action, with a business process for uncertainty, rather than simply repeating work or suppressing every apparent match.
We stopped the affected flow while purchasing and IT established which commitments were intended and which were duplicates. Purchasing retained authority over cancellation and supplier communication. My responsibility was the systems design, the investigation and the resources needed for correction. I did not describe the ₹34 lakh as money lost, because the case did not involve supply or payment against those cancelled orders. Nor did I call cancellation a saving. The repair expenditure remained a separate cost.
The decision changed our review of automated transactions. We asked what the buyer meant to do, what the system knew about the earlier attempt and how a repeated transmission would be treated. The correction was not evidence that every later integration was sound, and the absence of duplicate delivery did not make the original approval harmless. I retained the case because it shows a leadership error in the question I accepted: whether communication would eventually succeed, without enough attention to what business action success would repeat.
