Every manufacturing company needs to have a set of standard operating procedures (SOPs) to ensure compliance with safety and quality regulations. SOPs also help promote work consistency and prevent loss of product quality.
If you are new to writing SOPs, this article will give you a basic overview. We will discuss the importance of SOPs and outline the steps involved in creating an SOP for your manufacturing company. So, without further ado, let’s get started!
What is Manufacturing SOP?
A Manufacturing Standard Operating Procedure (SOP) is a step-by-step instruction guide for carrying out specific tasks in a manufacturing process. It is a foundational document that details the procedures to accomplish a particular job safely and effectively, ensuring product quality and worker safety.
SOPs are crucial in manufacturing because they provide structured guidance and promote consistency in daily operations, reducing the risk of errors, miscommunication, or variation in product quality. At the same time, they enable companies to comply with industry regulations and internal standards.
Why is SOP Important in Manufacturing?
SOPs hold a significant role in the manufacturing sector. Their importance transcends the mere instructions they provide; they shape the fabric of the operations, enforcing reliability and predictability. Here are six reasons that underscore their importance:
- Quality Assurance: SOPs ensure consistency in manufacturing, leading to product uniformity and adherence to quality standards.
- Safety: As they provide clear instructions for various processes, SOPs minimize the risk of accidents and ensure the safety of employees.
- Training: SOPs serve as a key resource in staff training, providing new employees with a detailed guide to the procedures and expectations of their role.
- Compliance: SOPs enable compliance with regulatory requirements and industry standards, as they outline the necessary steps to ensure products meet legal and safety guidelines.
- Productivity: Clear, step-by-step instructions can increase efficiency and productivity, reducing the time spent deciding or remembering the next step in a process.
- Accountability: SOPs provide an objective standard against which employee performance can be measured, promoting accountability and enabling fair evaluations.
Consequences of Noncompliance With Manufacturing SOPs
A well-structured manufacturing SOP will help streamline the entire production process while limiting the risk of errors. However, noncompliance with manufacturing SOPs could potentially lead to the following consequences:
Lack of Quality Control
Manufacturing SOPs can help produce high-quality products efficiently and consistently. However, failure to comply with these SOPs may lead to inconsistent outcomes in terms of quality, which may lead to client dissatisfaction.
Increased Costs
If SOPs are not followed, it could increase materials, labor, and time costs. SOPs help to minimize waste and maximize efficiency. Without SOPs, your company may needlessly spend more money than necessary to produce products.
Low Productivity
Manufacturing SOPs improve the overall efficiency of production operations. However, noncompliance with SOPs can decrease productivity due to errors, rework, and downtime.
Subjective Performance Evaluations
SOPs clearly define worker responsibilities and tasks. Without SOPs in place, it can be difficult to evaluate employee performance fairly. This could lead to frustration and resentment among your workforce. In addition, if management and workers are not following the same standard, expectations will become unclear. As a result, evaluations may become influenced by personal biases.
Communication Problems
SOPs are also responsible for communicating the process updates to workers. If workers fail to comply with manufacturing SOPs, there’s a higher chance of committing errors that could compromise their work quality and efficiency.
Increased Accident Risks
Safe work practices are essential in any manufacturing setting—SOPs help ensure employees follow the proper safety procedures. Without SOPs, workers may be more likely to take shortcuts, increasing the risk of accidents.
Having a clear and concise SOP for your manufacturing company is essential to avoid these potential consequences. Without it, you may struggle to maintain quality control, productivity, and communication among your workforce.
How to Write SOP in Manufacturing?
Now that we’ve discussed the consequences of noncompliance in manufacturing SOPs, it’s time to know how to make one for your business. Complying with regulations and producing consistent outputs doesn’t have to be a burden.
Preparing a comprehensive and well-written set of manufacturing SOPs will help the company perform routine tasks in the best, safest, and most efficient way possible.
Keep in mind that there’s no official standard in writing an SOP document for manufacturing. However, you will need to follow certain steps that will help make the process more effective:
Step 1: Determine Your Goal
Creating a manufacturing SOP starts with thinking of what you want to accomplish with it. Whether you’re starting a new process or trying to improve an existing one, determining the end goal will make it easier to write the entirety of the SOP document. Here are some examples of manufacturing SOP goals:
“The purpose of this standard operating procedure (SOP) is to ensure that correct steps are taken when using the milling machine.”
“The purpose of this standard operating procedure (SOP) is to ensure that correct steps are taken to select, prep, cure, and roast marinated barbecue ribs.”
Step 2: Define the Scope
The scope is the extent of your manufacturing SOP. It serves as a clear and concise detail on the limits or exceptions of your SOP and the people impacted by it. Here is an example of a scope:
- Q1: Where is the SOP to be used? A: In the manufacturing lab.
- Q2: Who is the SOP for? A: The SOP is for all employees who use the milling machine.
- Q3: Are there any specific limitations or exceptions to the SOP? It will only apply to the use of the milling machine and will not apply to other machines in the manufacturing lab.
Step3: Choose a Format
Keep in mind that there are various formats that you can use to write your SOP document. However, a typical manufacturing SOP uses a step-by-step format, which is straightforward to follow.
Other format options include the hierarchical format, which is similar to step-by-step but focuses on process flow. The narrative format is another option and is more flexible regarding organization.
You can use one or a combination of multiple SOP formats as long as they’re appropriate and can be easily understood by the people involved.
Step 4: Write Down the Procedures
Depending on your starter SOP’s focus procedures. For example, depending on your chosen format for writing SOPs for manufacturing, a good principle is the 5 C’s: clear, concise, current, consistent, and complete.
Ensure that your SOP is free of ambiguity and can be easily understood by anyone who reads it. SOPs should also be up-to-date, reflecting the most current best practices in manufacturing.
It is also essential to be consistent in the SOP’s voice and terminology throughout the document.
Lastly, make sure that your SOP covers all possible procedures related to your SOP’s focus. Here’s a simple step-by-step SOP sample in using a milling machine:
SOP for Milling Machine
- Check that all tools and safety devices are in place.
- Read the manual that comes with the milling machine before starting.
- Turn on the power to the milling machine.
- Adjust the speed and feed according to the SOP outlined in the manual.
- Begin milling the workpiece.
- Check the manual regularly to ensure that you are following the correct steps.
- When finished, turn off the power to the machine and clean up your work area.
- Report any problems with the machine to your supervisor.
