Providing quality management by validating a bill of materials in event-based product manufacturing. Some of the disclosed embodiments include a system and method for validating materials during manufacture of a product. Also disclosed are a method of validating that acceptable materials are being used on a machine during manufacture of a product, and one or more computer-readable media for storing a data structure representing a product specification in an event-based manufacturing system. The embodiments are operable in an intelligent manufacturing system including a process for converting raw materials to a product, a process control system including one or more sensors capable of generating an alarm in response to an event that results in one of waste, machine delay, or decrease product quality, a data logger associated with the process control system for obtaining event parameters associated with the event, a database on a server for recording event parameters obtained by the data logger, and a reporting system cooperatively associated with the database for reporting productivity parameters regarding the process derived at least in part from the event parameters.
