What Are the SOP Management Process Steps in the Pharma Industry?

The SOP management process in the pharmaceutical industry involves a structured, regulated approach to creating, approving, implementing, and maintaining SOPs in alignment with GMP and QMS requirements.

The main SOP management process steps in the pharmaceutical industry are as follows.

1. Preparation: Identify the need for a new SOP or a revision and draft it using a standardized format. The draft should define the purpose, scope, responsibilities, and procedure in accordance with GMP principles.
2. Review: The drafted SOP is reviewed by Subject Matter Experts (SMEs) and relevant department heads to verify accuracy, practicality, and compliance with internal and regulatory requirements.
3. Approval: QA and authorized personnel formally approve the SOP after confirming it meets company and regulatory standards. The document is assigned a unique version number and effective date.
4. Training: All affected employees are trained on the new or revised SOP before implementation to ensure understanding and consistent task execution.
5. Implementation: The approved SOP is distributed to relevant departments, replacing any outdated versions. The current version becomes the official document for operational use.
6. Maintenance: SOPs are periodically reviewed and updated to reflect process improvements, regulatory changes, or audit findings, ensuring continuous compliance and effectiveness.

In pharmaceutical document management, the document control module of a QMS plays a critical role in SOP management. Pharmaceutical document management ensures centralized document storage, version control, and real-time visibility of all SOPs across departments. It helps maintain compliance, data integrity, and full traceability throughout the SOP lifecycle by automating review, approval, and change control workflows.

1. Preparation

SOP preparation involves identifying the need for a new SOP or a revision based on process changes, new regulations, or internal improvements. During the preparation step, the responsible department drafts the document using a standardized company format that defines the purpose, scope, responsibilities, and detailed procedure. A clear understanding of the process to be documented is a prerequisite for creating a compliant SOP. Preparation must align with GMP and QMS requirements for written procedures and documentation control. Process owners or SMEs draft the SOP, while QA ensures the SOP follows approved templates and formatting standards.

SimplerQMS supports preparation by providing predefined templates, version control, and collaborative editing tools that streamline document creation and ensure consistency from the start.

2. Review

The review process ensures that the drafted SOP is technically accurate, practical, and compliant with both regulatory and internal requirements before approval. Reviewers include SMEs, QA staff, and department heads who examine the document to verify that instructions are clear, achievable, and aligned with related SOPs.

The review stage includes multiple review cycles to correct inconsistencies or ambiguities. All reviewers must sign off that the SOP meets GMP and QMS documentation standards before it is submitted for approval.

SimplerQMS facilitates the review process through automated routing, comment tracking, and audit trails that make document collaboration and revision management transparent and traceable.

3. Approval

The approval step formally authorizes the SOP for operational use, confirming that it meets all technical, procedural, and regulatory standards. Approval is granted only after QA verifies that all review comments are addressed and the content fully complies with GMP and internal policies. Approved SOPs receive a unique document number, version, and effective date to maintain control and traceability. Prerequisites for the approval stage include completion of all reviews and required signatures. QA or designated approvers are responsible for final authorization.

SimplerQMS simplifies this step by enabling secure electronic approvals with full audit trails, ensuring compliance with FDA 21 CFR Part 11 and EU Annex 11 requirements for electronic records and signatures.

4. Training

Training ensures that all affected employees understand and can correctly perform the tasks described in an SOP before it becomes effective. Training must occur before the SOP’s implementation date, and completion records must be maintained. Department supervisors and QA coordinate this activity to ensure employees are qualified and competent to carry out their responsibilities under GMP. Training effectiveness is often verified through acknowledgment forms, assessments, or on-the-job evaluations.

SimplerQMS automates training assignments, links SOPs directly to training records, and tracks completion progress to ensure only trained personnel perform GMP-regulated tasks.

5. Implementation

Implementation marks the point at which the approved and trained SOP becomes active. The effective date is communicated to all relevant teams, and obsolete versions are withdrawn to prevent confusion or misuse. Implementation ensures that the procedure is consistently followed through operations and that documentation reflects current practices. All training must be completed before this step, and the SOP must have an official effective date. Department heads and QA share responsibility for ensuring proper rollout and adherence.

SimplerQMS supports implementation by controlling document access, ensuring that only the latest approved SOPs are available to staff, and providing visibility into compliance across departments.

6. Maintenance

The maintenance stage ensures that SOPs remain accurate, relevant, and compliant throughout their lifecycle. SOPs are periodically reviewed and updated to reflect process improvements, regulatory updates, or audit findings. A defined review frequency, typically every one to three years, is set by QA or process owners to guarantee ongoing compliance with GMP and QMS requirements. All SOP revisions must follow the formal change control process, which includes impact assessment, approval by relevant stakeholders, and documentation of the rationale for changes. The maintenance process includes initiating revisions, re-approvals, and archiving previous versions for traceability.

SimplerQMS streamlines maintenance through automated review reminders, change control workflows, and permanent version archives, making continuous compliance and audit readiness effortless.

What Is the Role of Pharmaceutical QMS Software for SOP Management?

QMS software in the pharmaceutical industry is a validated digital platform that centralizes and automates all quality processes, including the creation, review, approval, training, and maintenance of SOPs. QMS software replaces manual, paper-based systems to ensure consistency, accuracy, and regulatory compliance across all departments.

QMS software streamlines SOP management by automating workflows, maintaining version control, enabling secure electronic signatures, and ensuring that only the latest approved SOPs are accessible. QMS software tracks document history, training completion, change control, and archiving, significantly reducing manual errors and administrative workload.

Key QMS functions that support the SOP lifecycle include document control, change management, training management, and audit trail functionality. QMS functionalities work together to manage SOP creation, approval, employee training, controlled updates, and secure record archiving.

The main benefits of using QMS software for SOP management are improved compliance, complete traceability, and enhanced operational efficiency. Automation enables faster approvals, stronger document control, and full visibility into every stage of the SOP lifecycle.

Pharmaceutical QMS software such as SimplerQMS supports regulatory compliance with international requirements such as FDA 21 CFR Part 11, EU GMP (EudraLex Volume 4), WHO-GMP, and ICH Q10 by ensuring data integrity, audit readiness, and controlled access to quality records.
