What is Production Operations Management?
This area of management is concerned with the planning, overseeing, and refining of all processes related to manufacturing. Production Operations Management encompasses all aspects of the transformation from input to output, including the planning of production, the sourcing of materials, manufacturing, inspection, and post-production processes.
While designing systems for production is a focus, it is also important to manage cost, quality, time, resources, and delivery. Consistency is key.
Production Operations Management provides answers to a range of critical issues for manufacturers. The questions include the following:
1. What is the right thing to produce? 2. What is the right quantity to produce? 3. What is the right combination of labor and machine resources to employ? 4. Do we have the required materials? 5. Is the production process operating on schedule? 6. Are our finished products of the required quality?
Production and Operations Management gives decision-makers the right information at the right time so they don’t have to rely on guesswork and the unreliable information of hand-written logs and slow response reporting.
Production and Operation Management: Scope
Although Production and Operation Management are two terms used together, they cover a wide range of activities.
Production Management is concerned primarily with the planning for, and the control of, the actual production of goods. This includes the scheduling and control of the use of materials, the scheduling and control of machines and work orders, and the control of quality.
Operations Management is much broader. It includes the control of inventory, procurement, maintenance, control of the workforce, control of the flow of goods, and control of processes.
Production Operations Management
Production and Operations Management provides manufacturers a framework to manage a number of inter-related problems. Examples of some of these problems include: machine break downs, rejection of quality, low work productively, excess inventory, and shortages of materials. These problems are frequently caused by a delay in material procurement or an inaccurate production schedule.
It enhances inter-departmental transparency. The production department understands what to build. The purchasing department knows what materials they will need to buy and management can verify if their orders are getting fulfilled.
Better control over operations will mean delays will become less likely, leading to an increase in the satisfaction of clients.
Key Elements of Production Operations Management
Production planning establishes the ‘what’, ‘how much’ and ‘when’ of manufacturing. This is done by balancing customer orders, forecasts, and existing inventory alongside the capabilities of the machines and the workforce, as well as the availability of the requisite raw materials.
Efficient planning assists in striking a balance to avoid the issues of over- or underproduction. Additionally, it allows manufacturers to focus on and fulfill urgent requests while keeping the overall production schedule intact.
Production scheduling focuses on the ‘when’ and the ‘who’ of production. It also determines which machines will be used to complete the production tasks and how much time will be allotted for each task.
A production schedule needs to be realistic and accommodate the shop floor’s production capacityas is, not as it should be. The creation of impractical schedules may make the production reports appear neat and orderly but will result in the production deadlines being missed and the schedule being altered repeatedly.
Management of materials makes sure all of the components and tools necessary for production are available. It also ensures that there is not excess stock, as that ties up working capital and adds costs for storage and possible damage or spoilage.
Shop-floor control provides insight into what is actually happening in production. It tracks a variety of metrics, including the status of work orders, how many items were produced, which machines were used, delays in production, quality issues, and the performance of different employees.
Shop-floor data provides managers with the ability to spot production issues before delivery deadlines are jeopardized. The ability to monitor data in real-time helps managers take actions to avoid problems sooner.
Quality Management
To avoid quality issues, quality must be managed continuously throughout production.
To assist with managing the quality of the product during production, POM supports quality inspections throughout production, helps capture defects, helps assign reasons for rejections, helps keep track of rework, and helps monitor persistent quality issues.
This data can assist with identifying the root cause of problems and help with the improvement of production processes in a manufacturing facility.
Equipment Maintenance
The current state of equipment has an impact on production capacity, quality, and timeliness of delivery. The lack of functioning equipment can halt a production line.
The planning of maintenance helps manufacturing organizations schedule routine maintenance, track equipment failures, keep service logs, and reduce unanticipated downtimes.
Challenges of Production Management
Many manufacturing organizations still rely on the use of spreadsheets, paper-based logs, verbal updates, and unintegrated software solutions. While these may work in a small manufacturing setup, as the complexity of the product and the volume of orders increase, they become difficult to manage.
A major challenge is the gap between what is planned for production and what is actually accomplished. Even with a well-developed production plan, the availability of machinery, labor, materials, and priority customer orders can change what was planned.
Yet another challenge is the lack of data. When production data is captured at the end of the shift, there is a high likelihood of errors and significant delays. Managers can be presented with outdated reports that do not reflect the true state of the shop floor.
Departmental silos can lead to incomplete information because non-data-sharing production, purchase, inventory, quality, and sales departments can negatively impact overall performance.
How Technology Improves Production Operations
Instead of multiple disconnected systems, digital production management systems combine planning, inventory, work orders, quality, maintenance, and reporting within a single system.
Because of this, managers can work with the system to compare the planned production output with what is produced, determine which work orders have been delayed, track the consumption of production materials, and evaluate the performance of production equipment. The production teams then gain better insight and more specific orders around what and when the priorities are, as well as the quantity and the due date.
Because of automation, the need for repetitive data-entry tasks is diminished and the accuracy of the remaining data is significantly improved. As an example, production orders automatically determine the materials required, and inventory is automatically adjusted when materials are issued or finished goods are received.
While technology does not improve operational discipline, it does create the means for teams to manage operations more effectively by supplying the required data and the visibility to do so.
Important Production Performance Metrics
Instead of blindly capturing data, manufacturers need to capture data related to production performance metrics that support their ability to make informed decisions.
Some of these production performance metrics may include production targets achievement, cycle time, rejection rate, rework rate, machine downtime, capacity, on-time deliveries, inventories, and overall equipment effectiveness.
The usefulness of a particular metric is only as good as the decisions that are based on that metric. For example, a rejection report that shows how many completed products were not accepted would only be a useful metric if the organization looked into the report to determine the reason for the rejection and then took steps to avoid similar rejections in the future.
Benefits of Effective Production and Operation Management
A well-designed and implemented Production and Operations Management system can lead to significant and quantifiable improvements to the overall efficiency and effectiveness of a manufacturing organization.
It can minimize delays during manufacturing, utilize resources more efficiently, manage stock levels, enhance the consistency of the final product, and ensure deliveries are on time. It provides managers with a better understanding of the costs associated with running the business and how the different areas of production are performing.
Having a well-defined operations management system allows employees to have a good understanding of their job descriptions and priorities. Employees are no longer required to jump around dealing with issues as they come, but rather are enabled to perform jobs in a timely and predictable manner, via the use of well-known and understood operation management systems.

Employees are no longer required to jump around dealing with issues as they come, but rather are enabled to perform jobs in a timely and predictable manner, via the use of well-known and understood operation management systems.
The largest positive impact of well-defined operation management systems is that they support and allow for growth.
The first area for improvement should be the systems and processes within the manufacturing facility. This should include finding areas that are repetitive and time consuming, as well as identifying areas that require a high degree of manual intervention.
Having a well-defined system of standard operating procedures for management of planning, issuing materials for production, production reporting, quality inspections, maintenance of equipment, and handling finished goods is essential for effective operation management systems.
After this step, management should define and evaluate related performance metrics. A variety of technologies can be adopted for real-time data and inter department connectivity.
Involvement and support from employees is critical for the success of this improvement, as shop floor production employees have the best understanding of the challenges and limitations of the systems. This gives employees the ability to define and establish less complex but more effective systems.
In manufacturing, one of the most important areas to develop and be efficient in is production and operations management, as this is the main area of a business that provides stable cash flow. The focus of effective systems and procedures should be on integrating the planning and execution phases and providing control over all aspects of operations.
Having a strong focus and a well-defined operations management system allows businesses to focus on their operations rather than the management of operations. Rather than waiting for delays in production and needing to resolve issues, businesses are now able to implement preventative measures to reduce operational risks.
Manufacturers are able to deliver customer orders with greater confidence because they are able to combine skilled teams with technology and accurate production data into standardized processes.
