How to Write Standard Manufacturing Work Instructions

This article will discuss the importance of everyday work and guide you on how to write standard manufacturing work instructions.

When it comes to business and entrepreneurship, every employee has a different way of doing work. Each worker offers a diverse background experience, depth of skill, and a different work process. These slight differences can be significant enough to introduce variation into a company’s workflow—something you should avoid if you want fluidity and cohesiveness within your operations. 

If your NPI (new product introduction) engineers haven’t prepared a standard work instruction sheet, it’s time to write one. This article will discuss the importance of everyday work and guide you on how to write standard manufacturing work instructions for your company. 


What are Standard Manufacturing Work Instructions?

Standard Manufacturing Work Instructions (SMWIs) are detailed, step-by-step guidelines that outline the procedures and best practices for carrying out specific tasks in a manufacturing environment. These instructions are designed to standardize processes, improve efficiency, ensure consistent product quality, and promote safety among workers.

SMWIs typically include:

  • Purpose: A brief explanation of the task or process, its importance, and how it contributes to the overall manufacturing operation.
  • Scope: The range of activities the work instruction covers, including any limitations or restrictions.
  • Responsibilities: The roles and responsibilities of each team member involved in the process, from operators to supervisors.
  • Tools and Equipment: A list of all tools, equipment, and materials required to perform the task, along with any necessary maintenance or calibration procedures.
  • Procedure: A step-by-step task description, often accompanied by visual aids such as diagrams, photographs, or videos. This should be clear, concise, and easy to follow, with an emphasis on accuracy and consistency.
  • Quality Control: Information on how to inspect and verify the quality of the completed task, including any required testing, measurements, or documentation.
  • Safety Precautions: Guidelines for maintaining a safe working environment, including personal protective equipment (PPE), proper handling of hazardous materials, and adherence to relevant safety regulations.
  • Documentation: A record of any relevant data or information generated during the process, such as production logs, test results, or inspection reports.


By implementing Standard Manufacturing Work Instructions, companies can reduce variability in their processes, minimize errors, increase productivity, and maintain high quality across their products.


Why are Standard Manufacturing Work Instructions Important?

Standard Manufacturing Work Instructions (SMWIs) are essential for several reasons that contribute to the overall success and efficiency of a manufacturing operation:

Consistency and Quality

SMWIs ensure that every worker follows the same procedures, leading to consistent output and maintaining high product quality standards. This helps to minimize defects, reduce waste, and ultimately enhance customer satisfaction.

Efficiency and Productivity

By providing clear and concise instructions, SMWIs streamline the manufacturing process, reducing the time spent deciphering complex tasks or correcting errors. This leads to increased efficiency and productivity while also optimizing resource utilization.


SMWIs outline safety precautions and guidelines for handling hazardous materials or operating equipment. This helps to minimize accidents, prevent injuries, and create a safer working environment for employees.

Training and Skill Development

Well-written work instructions are a valuable training resource for new employees, helping them quickly learn and adapt to the company’s processes. They also serve as a reference for experienced workers to refresh their knowledge or learn new skills.


Many industries have strict regulations and quality standards that must be followed during manufacturing. SMWIs help ensure that all procedures comply with relevant laws and industry standards, reducing the risk of non-compliance penalties or fines.

Continuous Improvement

SMWIs provide a baseline for evaluating and improving processes over time. By regularly reviewing and updating work instructions, companies can identify areas for improvement, implement changes, and measure their impact on efficiency and quality.

Knowledge Preservation

Documenting processes in the form of SMWIs ensures that valuable knowledge is retained within the organization. This is particularly important when experienced employees retire or leave the company, as their expertise can be passed on to others through well-documented work instructions.

Standard Manufacturing Work Instructions are crucial in maintaining consistency, quality, safety, and efficiency in a manufacturing environment. They serve as a foundation for training, skill development, and continuous improvement, ultimately contributing to the organization’s overall success.

Tips to Write Manufacturing Work Instructions

To ensure that your SMWIs are effective and compliant, consider the following tips before beginning to write:

Standardize the Work

The core concept of manufacturing instructions is to follow sets of rules that will be applicable to a particular product. Thus, the first step is to standardize the work, no matter who does it, and ensure everyone follows the same procedures. This way, you can be sure that every unit produced is identical, avoiding costly mistakes or reworks.

Following the standard manufacturing process, a straightforward improvement to the work instructions identifies which tasks will be completed by whom. This small change can greatly reduce impatience, eliminating wasted time when people don’t know who has responsibility for what.

Write it With People Who Do the Work

Speaking of people not knowing their responsibilities, the instructions must be written with those who do the work in mind. You should involve them in drafting the manufacturing procedures, ensuring they can understand and follow them without problems.

Writing manufacturing work instructions for your employees is a great way to empower them by giving them access to all the information they need while working. Not only does this improve overall efficiency, but it also reduces the need for other people to answer questions, making them more productive!

Focus on Just One Task at a Time

Another crucial thing to remember when writing manufacturing work instructions is that you should focus on just one task. This can be difficult if you are writing work instructions for an entire production line, but if you need to troubleshoot a problem later, it will help immensely.

This way, when diagnosing an issue that arises in the future, you can better identify where the problem is occurring and which steps in your process are causing it. This will make identifying the source of errors or disruptions much more effective!

Make it Visual

The manufacturing work instructions you create will ensure that your procedures are visual wherever possible. However, this can only be accomplished by creating a visual process map of the production line. Or including 3D models within the document itself.

This will give workers an easy-to-understand map or virtual representation of their work processes. And can help eliminate confusion and ensure that everything is completed the same way every time.

Keep it Concise and Simple

When writing work instructions, it’s important to remember that you should keep them concise and straightforward. Avoid using long sentences with lots of clauses and use plain language that makes sense.

This way, the instructions will be easy to understand and follow without issues, allowing employees to work efficiently and produce quality products. Remember: if you’re writing instructions for power equipment like milling machines or lathes, use technical jargon sparingly! You could end up confusing your workers and making your instruction less effective.

Test Your Instructions

Finally, the last tip for writing manufacturing work instructions is to test them before using them. This can be done by getting a few of your employees or staff members together. And having them go through the entire process while you watch ensures they aren’t struggling with any steps.

This way, you can correct your instructions to ensure they are as efficient and straightforward as possible – something any company would want in their manufacturing work instructions!

Get Employee Buy-In

A common mistake that most big-name factories make is treating their low-level employees as disposable resources. By getting employee buy-in, you can increase overall efficiency like never before!

This is done by having the workers craft the procedures they will use daily. If they’re writing them with you, they will feel more responsible for completing their tasks correctly and putting in extra effort to ensure everything goes smoothly.

Track Data Regularly

Here’s another way to improve overall efficiency when writing manufacturing work instructions: track your data! This is done immediately after production. Using a checklist that workers can use to indicate whether or not they completed their task correctly.

This information is critical in allowing you to benchmark your production performance. If checks indicate that a worker constantly struggles with a particular task, you can work with them to find the source of the problem and fix it as soon as possible.

Keep Instructions Updated

As a final manufacturing work instructions tip, it’s important to remember what will sometimes happen when your product or process evolves. As a result, your instructions will need to be updated as well! Therefore, keeping track of any changes and ensuring they integrate appropriately into your procedures is essential.

This way, you can ensure that workers always have the most up-to-date information and avoid difficulties during production!

Train Your Process Engineers

Finally, as the last manufacturing work instructions tip, you must train your process engineers to write effective procedures.

These individuals must understand that they will be writing the procedures your workers will use daily. And as such, they should take their jobs very seriously. To avoid poor procedure implementation problems, ensure your process engineers know exactly what they’re writing and why it’s essential.
