Abstract: An apparatus for supply-chain management includes memory storing application software coupled with an enterprise resource planning (ERP) system and processing circuitry configured execute the application software. Executing the application software causes the apparatus to generate a graphical user interface (GUI). The apparatus initiates a planning module of the GUI to build a portfolio including products and a customer, select a product, input a purchase plan, perform an analysis of the purchase plan, and output the purchase plan to a collaboration module. The apparatus initiates the collaboration module to generate a supply plan based on the purchase plan, compare the purchase plan and the supply plan to data received from the ERP system, modify the purchase plan and the supply plan, and output the modified plans to a deviation management module. The apparatus initiates the deviation management module to determine whether the modified purchase plan should be adjusted.
