a. Start-ups are not process-driven. Mature orgs invest in ERP system, inventory management & robust processes enforced strictly with engineers. Such errors are unavoidable in startups.
b. Tech's job isn't purchase. Ops should help check & match part numbers as soon as receipt. Bring an ERP system, track inventory & raise tickets helping engineers to test on a timely manner.
c. This is a result of lack of attention to detail & coordination between teams. Only Tech team can do tech related tasks. Hard for a small ops team to track 400 tech parts and its compatibility.
d. Bring in a process for engineers to verify part no's in quote & P.O. Upon delivery, concerned engineer must strictly initiate testing and track inventory.
a. Find some cameras being used internally in customer projects and get them re-allotted to setting up the demo, as the exhibition is the urgent need
b. Attempt to find alternate vendor(s) with smaller lead time as soon as possible and procure from them even if the cameras come at a premium cost but with immediate delivery.
c. Convince the existing international vendor to find cameras from their existing customers, and loan them until the demo is over
d. Work with the R&D team to change demo design to fit what we can predictably procure with the time you have.
