Specialty Packaging Corporation, Part A
Julie Williams had a lot on her mind when she left the conference room at Specialty Packaging Corporation (SPC). Her divisional manager had informed her that she would be assigned to a team consisting of SPC’s marketing vice president and several staff members from their key customers. The goal of this team was to improve supply chain performance, as SPC had been unable to meet all the demand of their customers over the past several years. This often left SPC’s customers scrambling to meet new client demands. Julie had little contact with SPC’s customers and wondered how she would add value to this process. She was told by her division manager that the team’s first task was to establish a collaborative forecast using data from both SPC and their customers. This forecast would serve as the basis for improving their performance as they could use this more accurate forecast for their production planning. With this in place, SPC would have a key tool to improve delivery performance.
SPC
SPC turns polystyrene resin into recyclable/disposable containers for the food industry. Polystyrene is purchased as a commodity in the form of resin pellets. The resin is unloaded from bulk rail containers or overland trailers into storage silos. Making the food containers is a two-step process. First, resin is conveyed to an extruder, which converts it into polystyrene sheet wound into rolls. The plastic comes in two forms: clear and black. The rolls are either used immediately to make containers or are put into storage. Second, the rolls are loaded onto thermo-forming presses, which form the sheet into containers and trim the containers from the sheet.
