What Is a Production Order?
A production order is an internal document or directive issued by a manufacturing company's control department to its production department, authorizing the manufacture of a specific quantity of a product within a defined timeframe. This critical component of Operations Management serves as the formal instruction to commence the manufacturing process. It outlines all necessary details, from the type and quantity of items to be produced to the raw materials and resources required. The issuance of a production order often triggers a series of actions, including the reservation of components from inventory management or the generation of procurement orders if materials are not in stock.,11
History and Origin
The concept behind a production order has roots in the evolution of organized manufacturing, driven by the need for efficiency and control over complex processes. Before the industrial revolution, production was largely artisanal and localized, with less need for formal, standardized directives. The advent of factory systems and the increasing complexity of goods necessitated structured approaches to managing production. A significant turning point in the history of production management was the introduction of the moving assembly line by Henry Ford in 1913. This innovation, which dramatically reduced the time to build a car by bringing the work to the workers, emphasized the need for precise planning and coordination, which a formal production order facilitates.10,9,8 This shift from skilled craftsmen performing multiple tasks to specialized workers performing single, repetitive tasks underscored the importance of clear instructions for each stage of the production planning process.7
Key Takeaways

- It initiates the allocation of resources and scheduling of production activities.
- Production orders are central to efficient manufacturing process control and resource utilization.
- They provide a basis for tracking work in progress and managing costs.
Interpreting the Production Order
A production order is a comprehensive blueprint for manufacturing a product, offering detailed instructions for the shop floor. It is interpreted as the official mandate to produce, providing clarity on what needs to be done, by when, and with what resources. Key elements within a production order typically include the specific product code, the quantity to be manufactured, the planned start and end dates, and a reference to the bill of materials (BOM) that lists all necessary components and their quantities. It also often specifies the routing, which dictates the sequence of operations and the work centers involved.6 This level of detail allows for precise capacity planning, ensuring that machinery and labor are optimally utilized. Effective interpretation of a production order minimizes errors, reduces waste, and helps maintain a smooth production flow, contributing to overall operational efficiency.
Hypothetical Example
Imagine "Shiny Bikes Inc." has received a large sales order for 500 units of their "Mountain Explorer" bicycle. The sales department relays this to the production control department.
- Creation of Production Order: The production control department issues a production order for 500 Mountain Explorer bicycles, assigning it a unique identifier, say, PO-2025-001. The order specifies a start date of August 15, 2025, and a completion date of September 15, 2025.
- Material Allocation: The system checks the bill of materials for the Mountain Explorer, which includes frames, wheels, gears, seats, and handlebars. It then checks inventory management for these components. If all 500 sets of components are in stock, they are automatically reserved for PO-2025-001. If, for instance, only 300 frames are available, a procurement order is automatically generated for the remaining 200 frames.
- Routing and Scheduling: The production order also details the sequence of operations: frame assembly, wheel assembly, gear installation, painting, and final assembly. Each step is assigned to a specific work center within the factory. The production schedule is updated to reflect the new demand on each work center's capacity planning.
- Execution and Tracking: As manufacturing progresses, workers or automated systems update the status of PO-2025-001. This allows for real-time tracking of work in progress and provides visibility into the production status, ensuring the order stays on track for its completion date.
Practical Applications
Production orders are fundamental to manufacturing, spanning various industries from automotive to electronics to consumer goods. They are integral to modern Enterprise Resource Planning (ERP) systems, which automate much of the order creation, tracking, and resource allocation. For example, in the United States, the National Institute of Standards and Technology (NIST) supports manufacturing competitiveness through its Manufacturing Extension Partnership (MEP) program, which aids small and medium-sized manufacturers in optimizing operations, including robust production order management.5,4 Effective production order management enables companies to implement strategies such as Just-in-time (JIT) manufacturing, minimizing holding costs for finished goods and raw materials by producing only what is needed, when it is needed. Furthermore, the data from completed production orders feeds directly into cost accounting, allowing businesses to accurately determine the actual cost of production for each item.
Limitations and Criticisms
While essential for organized manufacturing, production orders face limitations, particularly in dynamic or highly complex environments. One major criticism stems from their inherent inflexibility once issued. If sudden changes occur in demand forecasting, material availability, or equipment breakdowns, adjusting an active production order can be cumbersome and lead to delays and inefficiencies. This can be exacerbated by disruptions in the broader supply chain. For instance, recent global events have highlighted how vulnerabilities in supply chains, such as material shortages or transportation delays, can significantly impede planned production, forcing companies to halt or drastically alter production orders.3,2 Such disruptions underscore the challenge of maintaining precise production planning in an uncertain economic climate. Additionally, over-reliance on rigid production orders without agile management systems can lead to increased lead time and higher costs if not managed with sophisticated quality control and real-time adjustments.
Production Order vs. Work Order
The terms "production order" and "work order" are often used interchangeably, particularly in casual conversation, but in a formal operations context, they serve distinct purposes. A production order is typically a broader document, acting as the high-level authorization to manufacture a product. It encompasses the entire process of converting raw materials into a finished good, usually tied to a sales order or forecasted demand for a specific item. It often triggers sub-tasks and resource allocations across various departments. A work order, by contrast, is generally a more granular instruction, detailing a specific task or set of tasks that need to be performed. While a work order can be part of a larger production order (e.g., a work order for assembling a specific sub-component of the final product), it can also be issued independently for maintenance, repair, or other non-production-related tasks. In essence, a production order dictates what to make and how much, while a work order focuses on how a specific part of that making process, or another operational task, should be carried out.1
FAQs
What information is typically included in a production order?
A production order usually contains the product code, quantity to be produced, planned start and end dates, the bill of materials (listing required components), and the routing instructions (sequence of operations and work centers). It may also include details for quality control checks.
Why are production orders important for manufacturing businesses?
Production orders are crucial because they formalize the manufacturing process, ensure that resources like raw materials and labor are allocated efficiently, and provide a clear schedule for production. They are vital for tracking work in progress, controlling costs, and meeting customer deadlines.
How do production orders relate to inventory?
A production order directly impacts inventory management. Upon creation, it triggers the reservation of necessary raw materials from stock. If materials are insufficient, it can initiate procurement orders to replenish inventory, ensuring production isn't delayed by shortages.
Can a production order be changed after it's issued?
Yes, a production order can be changed, but modifications can be complex and may lead to delays or increased costs. Changes are often necessary due to unexpected events like material shortages, equipment malfunctions, or shifts in demand forecasting. Modern Enterprise Resource Planning (ERP) systems help manage these changes, but flexibility is still a challenge.
