What Is SOP In Warehouse – Quick Guide And Template


An SOP describes a procedure and tells an operator how to perform it. SOPs are useful in most work environments but are essential for organizations whose operations are process-driven, such as life sciences companies and manufacturing companies. SOPs, along with staff training, transfer expertise from one department to another. In a medical device company, for example, scientists in research and development pass on to the manufacturing department their knowledge of a product they have designed, thanks to SOPs. Standard Operating Procedures (SOPs) for warehousing – particularly apply to certain tasks and the use of specialized machinery or new equipment.

Manufacturers that operate internationally also rely on SOPs to standardize processes across their factories. For example, a Japanese car manufacturer will train its staff in the United States on key manufacturing processes, then use SOPs to ensure that every car the company sells is of the expected quality, regardless of location.

The uses of SOPs by organizations are diverse:

  • Ensure process consistency and reproducibility
  • Facilitate training by giving trainees a point of reference
  • Make it easier to cross-train employees on tasks they don’t usually do
  • Reduce security risks and other hazards by specifying how to avoid and prevent them
  • Have a basis for process evaluation and improvement
  • Comply with regulations and/or quality standards

Types of the SOP

The formats of SOPs are as varied as the operational activities. An SOP can be in the form of a checklist, flowchart (or any other graphic), hierarchical steps, or annotated photos. However, consistency and traceability of SOPs generally need to be ensured in regulated environments. Procedures should include a simplified document identification and control system.

A valid SOP should include the company name, descriptive title, identification, and control numbers, purpose, scope, responsibilities involved (specific tasks, assignment of activities to employees, certification and qualification requirements, etc.), and a step-by-step procedure. Depending on the nature of the process described, the SOP may include calculations for data management.

Consequences of non-compliance with standard operating procedures (SOPs)

A good standard operating procedure is designed to streamline the production process while minimizing the risk of error. Non-compliance with standard operating procedures could lead to the following consequences:

Lack of quality control

Standard operating procedures help produce consistently high-quality products. Failure to follow these standard operating procedures can lead to inconsistent quality results and dissatisfied customers.

Low productivity

Standard operating procedures are designed to improve efficiency. Non-compliance makes it difficult to achieve maximum productivity since operational deadlines vary for each employee.


Subjective performance evaluations

Standard operating procedures clearly define the tasks and responsibilities of team members. Objective performance evaluations are conducted by measuring actual performance against standards set by industry standard operating procedures. If management and employees do not follow the same standard, expectations become blurred and evaluations can be influenced by personal biases.

Communication breakdown

Standard operating procedures communicate process updates to employees. If workers do not follow standard operating procedures, they risk making mistakes that could compromise the quality and efficiency of their work.

Increased risk of accidents – Safe work practices is often incorporated into company standard operating procedures. Non-compliance can put employees at greater risk of work-related accidents or injuries.

How do SOPs improve warehouse operations?

  • Consistency and reliability of service. SOPs are used to establish operating procedures that help prevent and reduce errors.
  • Savings measures. Shipping errors can cost money. A well-designed SOP reduces the chance of error and increases operational efficiency.
  • Legal compliance. SOPs document policies, procedures, and processes that demonstrate compliance with legal requirements.
  • Safety. A properly written SOP reinforces your organization’s core values ​​and charter to ensure the safety and well-being of your employees.

How to write an SOP?

Complying with regulations and producing consistent results doesn’t have to be an obstacle course. Preparing a well-written SOP document can guide employees in performing routine tasks in the best and safest way possible. There is no official standard for writing an SOP document. However, there are certain steps that can help in writing an effective SOP.

Step 1: Determine the objective

Writing your SOP for your business starts with thinking about what you want to accomplish. Whether starting a new process or improving an existing one, determining the purpose or objective makes it easier to write the SOP document.

Step 2: Define the scope

The scope defines the scope of your SOP document. It clarifies details such as limitations or exceptions to the procedure, and who will use it or who will be impacted.

Step 3: Choose a format

There are different formats for writing an SOP document. A standard operating procedure typically uses a step-by-step format, which is simple and easy to follow. There is also the hierarchical format which is similar to the previous one, the only difference is that it provides more detailed and specific instructions for each step. Finally, the flowchart format where the processes are illustrated. This solution is most suitable for processes that require decision-making. You can choose to use one or a combination of them, as long as it is appropriate and easily understood by your audience.

Step 4: Write the procedures

Depending on the format you have chosen, start writing the procedures according to your purpose. A good principle to follow when writing is the 5 Cs: clear, concise, correct, courteous, and complete. This takes the guesswork out of the procedure and ensures that every step is consistent.

Step 5: Review and update if necessary

After writing your SOP document, review and test it with other team members before sending it to stakeholders for approval. Once approved, it will then be implemented and shared with relevant employees. However, it doesn’t stop there. SOPs should be continually reviewed and updated, preferably every 6-12 months or as needed.

SOP management: challenges

Despite the ubiquity of technology, most businesses continue to rely on paper-based processes even today. In most cases, SOPs, created using Microsoft Word, are printed and stored in binders, which are then physically routed from one approval department to another. Once approved, the contents of the binder are photocopied so that each department concerned has one available. In a small organization, this process may be sufficient, but for the majority of companies, a manual system poses many problems:


The process of routing, reviewing, and approving an SOP can be slow and inefficient, especially if an organization generates hundreds of thousands of SOPs and the employees responsible for reviewing and approving them are located in different locations or moving. SOPs can be lost during their routing or drowned in the middle of paper piled up on a desk or in a mailbox (in the case of routing by e-mail). Searching and retrieving SOPs requires staff to sort through a huge volume of paper documents. The same goes for updating them. Besides going through a similar routing and approval process during the review, outdated paper documents should be discarded.

Bad communication

In a manual system, the quality processes are not linked, which complicates the transmission of information between the people who manage these processes. To expedite the approval of an SOP, its author must make calls, send e-mails or go directly to the personnel in charge of this task. All this for a single SOP. The number of callbacks by phone, email, or person is multiplied by the number of SOPs the employee is responsible for. In a rapidly growing organization (such as a 24/7 business with multiple locations around the world), SOPs are likely to change constantly, with the risk that affected individuals will not be notified early enough.

Insufficient training

It’s detrimental if employees aren’t made aware of new SOPs (or recent changes) quickly, but the lack of proper training on new SOPs has more serious consequences. This failure is inherent in a manual system that is not linked to the training control process. In this situation, employees who do not receive proper training are likely to use the new SOPs incorrectly.

Ineffective documentation

The effectiveness of SOP implementation has a direct impact on product quality, which is why it is essential for organizations to provide accurate and up-to-date information in SOPs. However, updating SOPs manually requires considerable time and effort. It is then neglected by employees at the risk of creating compliance problems. It is also unreliable to expect employees to think at every opportunity to note changes in an SOP, and to add the author, reason, and date to the document.

Lack of revision control

Businesses that depend on a manual system regularly complain about the difficulty of getting rid of outdated documents. Even after reviewing and approving the SOPs, old documents may end up on the shop floor. Another problematic situation can arise from the simple fact that a filing cabinet containing documents that have not been approved ends up in the hands of employees because it was lying on a desk. In both cases, the use of unverified SOPs can be the source of non-conformities.

For these reasons, it is better to take a system to reduce paperwork and save time.
