Umoya Rail Engineering (KwaZulu-Natal, Durban) supports rail-yard operations and experiences frequent unplanned stoppages when specific bearings, seals, and motor components are unavailable. Engineering supervisors want faster availability, maintenance planners want predictable replenishment rules, stores managers want fewer emergency issues, and finance wants clearer justification for stocking decisions. The category team has collected these views but cannot translate them into one consistent set of success criteria for the spares category plan. Which sequence should the team follow before finalising category objectives?
