A procedure defines documented steps for tasks, ensuring consistency, safety, and compliance in regulated environments such as aviation or healthcare.
A procedure is a formally documented, structured sequence of instructions that guides how a specific task or process should be performed to achieve predictable and compliant outcomes. Procedures are the backbone of operational discipline, especially in highly regulated sectors such as aviation, healthcare, manufacturing, and IT.
In these environments, procedures are meticulously crafted to ensure that every step—no matter how routine or complex—is executed correctly and safely. This not only enables organizations to meet regulatory requirements but also minimizes human error, supports training, and enhances overall quality and efficiency.
Procedures are not optional or suggestive guidelines. They are enforceable requirements, often subject to audits and legal scrutiny. Deviation from a procedure is only permitted when authorized, such as in abnormal or emergency situations, and such deviations are typically documented for review.
The concept of an established method of operation is central to high-reliability organizations. It means that tasks are performed in a uniform, codified manner every time, leaving little room for ambiguity or improvisation.
For example, in aviation, ICAO Annex 6 mandates that every operator maintain an operations manual containing all normal and emergency procedures, which must be followed by flight crews and ground staff. These procedures are reviewed and approved by regulatory authorities, and their use is enforced through training, audits, and recurrent assessments.
Standardization through procedures ensures:
Procedures underpin the safe, efficient, and compliant functioning of organizations. Their benefits include:
| Term | Definition |
|---|---|
| Standard Operating Procedure (SOP) | Step-by-step instructions for routine tasks; the foundation of daily operations. |
| Method of Procedure (MOP) | Detailed procedure for complex or high-risk tasks, with pre- and post-checks and required approvals. |
| Emergency Operating Procedure (EOP) | Focused guidance for abnormal or emergency situations, emphasizing rapid, safe response. |
| Quality Control | Systematic activities to ensure outputs meet specified standards, often defined within procedures. |
| Regulatory Compliance | Adherence to laws and standards, demonstrated through documented, auditable procedures. |
| Roles and Responsibilities | Clear allocation of duties for each step in a procedure, ensuring accountability. |
A well-designed procedure is clear, concise, and logically organized. Key sections typically include:
This structure ensures comprehensiveness, user-friendliness, and enforceability, as recommended by standards like ISO 9001 and ICAO documentation.
SOPs provide clear, step-by-step instructions for routine or repetitive tasks. They are optimized for consistency, safety, and efficiency, and are often supported by checklists or digital tools.
Example SOP Applications:
MOPs are used for complex, non-routine, or high-risk tasks that require coordination across teams and detailed verification.
Example MOP Applications:
EOPs outline immediate actions for abnormal or crisis events, using explicit, direct language to facilitate rapid response.
Example EOP Applications:
Aviation:
Procedures govern every aspect, from flight operations to maintenance and air traffic control, as mandated by ICAO, EASA, and FAA.
Healthcare:
Procedures standardize patient care, medication handling, and emergency response, ensuring patient safety and regulatory compliance.
Manufacturing:
Procedures control equipment operation, maintenance, quality inspections, and response to incidents.
IT/Data Centers:
Procedures manage system upgrades, backups, security updates, and disaster recovery.
Hospitality:
Procedures ensure consistency in service delivery, food safety, and emergency evacuation.

Steps:
Effective procedures include troubleshooting sections that help users resolve common problems and specify escalation contacts for unresolved issues. For example, if a maintenance step fails, the procedure may direct the user to verify connections or escalate to engineering support.
Organizations such as ICAO, EASA, and FAA mandate the creation and maintenance of procedures for all critical operations. Procedures must be:
Procedures are integral to the hazard identification, risk assessment, emergency response, and continuous improvement elements of an SMS. They provide the structure for safe operations and document lessons learned for future improvement.
Modern organizations deploy procedures via digital platforms—mobile apps, electronic flight bags, workflow management tools, and intranet portals. Digital procedures offer real-time access, automated version control, built-in checklists, and usage analytics, increasing compliance and reducing errors.
A procedure is more than a set of instructions—it’s a critical control for safety, quality, compliance, and efficiency across industries. Well-designed, regularly updated procedures enable organizations to deliver reliable, safe, and legally compliant operations, even in the most complex and regulated environments.
A procedure is a documented set of instructions defining the exact steps needed to complete a specific task or process. In operations, procedures are designed to ensure consistency, safety, and compliance, reducing variability and minimizing the risk of human error.
Policies define the guiding principles or rules for an organization, while procedures provide the detailed, step-by-step instructions for carrying out tasks in accordance with those policies.
In regulated industries like aviation or healthcare, procedures are essential for legal compliance, safety, quality assurance, and auditability. They standardize operations, reduce risks, and form a key part of training and incident investigation.
SOPs are a type of procedure that provides clear, detailed instructions for routine, repetitive tasks. They ensure every employee carries out the task in a consistent, safe, and compliant manner.
Procedures must be regularly reviewed, tested, and updated to reflect changes in regulations, technology, or operational experience. Effective version control, user feedback, and periodic audits ensure ongoing relevance and compliance.
