A 2023 review followed sixty urgent spare-parts orders with a four-day customer promise. Forty-six missed that period. A separate fleet report showed 98% of scheduled trucks departing on time, which initially made the service problem look inconsistent with the transport account. The measures described different populations and started their clocks at different points. Parts could wait for consolidation before a truck entered the departure schedule.
Transport colleagues reasonably valued reliable departures and efficient loads. I did not ask them to abandon those measures. I asked that the operating decision include the waiting before dispatch became a scheduled activity. A customer did not gain a shorter wait because the eventual truck left punctually. The service promise needed a route appropriate to urgent parts, with commercial and technical owners retaining the relevant terms and approved-item requirements.
We funded an ₹85 lakh small-parcel service programme. In the following defined sixty-order cohort, eighteen orders missed four days, compared with forty-six in the earlier group: twenty-eight fewer late orders between those observations. The cohorts were not a matched causal study, and the result does not establish a universal service rate or prove that every difference came from the programme. It does show why the complete customer interval belonged in the review alongside fleet punctuality.
The case changed our operating discussion from defending one internal measure to understanding the sequence behind the promise. We retained the remaining eighteen late orders rather than describe the programme as a complete solution. The ₹85 lakh was programme funding, not an achieved saving. I would use both the observed improvement and the unresolved cases to guide the next review, while keeping scheduled-departure reliability distinct from order-level compliance with a customer commitment.
