There has been some controversy regarding the proper procedures to follow and the amount of paperwork involved, but much of that has improved in current ISO 9000 revisions. The history of production and operation systems began around 5000 B.C. Trends in modern operations management. Frank Gilbreth is also responsible for introducing the flow process chart in 1921. This was explained by its originators in a book they published in 1948 called "Method-Time Measurement".[20]. This paper inspired a large body of mathematical literature focusing on the problem of production planning and inventory control. Schwab, G.J. Services were largely local in nature (except for railroads and telegraph) and owned by entrepreneurs and families.

Recent trends in the field revolve around concepts such as: A production system comprises both the technological elements (machines and tools) and organizational behavior (division of labor and information flow). These models usually involve the calculation of cycle stocks and buffer stocks, the latter usually modeled as a function of demand variability. MRP therefore is a planning tool to manage purchase orders and production orders (also called jobs). Beginning in 1955 McDonald's provided one of the first innovations in service operations. Ransom Olds was the first to manufacture cars using the assembly line system, but Henry Ford developed the first auto assembly system where a car chassis was moved through the assembly line by a conveyor belt while workers added components to it until the car was completed. [26] MRP II was developed by Gene Thomas at IBM, and expanded the original MRP software to include additional production functions. One important example of how system throughput is tied to system design are bottlenecks: in job shops bottlenecks are typically dynamic and dependent on scheduling while on transfer lines it makes sense to speak of "the bottleneck" since it can be univocally associated with a specific station on the line. Experience has shown one manager a way to determine the economical size of lots"[17]. This was accomplished by adhering to their system of delivering the goods and the service to the customers at the lowest possible cost.

Lean manufacturing is an approach to production which arose in Toyota between the end of World War II and the seventies. Professor Jaya Singhal, Merrick School of Business, University of Baltimore is the Executive Editor. Parts are kept in containers with their respective kanbans, The downstream station moves the kanban to the upstream station and starts producing the part at the downstream station, The upstream operator takes the most urgent kanban from his list (compare to, The downstream operator takes the production kanban from his list, If required parts are available he removes the move kanban and places them in another box, otherwise he chooses another production card, He produces the part and attach its respective production kanban, Periodically a mover picks up the move kanbans in upstream stations and search for the respective parts, when found he exchanges production kanbans for move kanbans and move the parts to downstream stations.
