1. Purpose
The purpose of this Standard Operating Procedure (SOP) is to establish guidelines for adjusting batch sizes in ointment production to align with market demand, production efficiency, and resource availability while ensuring compliance with GMP regulations.
2. Scope
This SOP applies to manufacturing, production planning, and quality assurance personnel involved in determining and adjusting batch sizes in accordance with production needs.
3. Responsibilities
- Production Manager: Ensures batch size adjustments comply with GMP and regulatory requirements.
- Planning Department: Analyzes market demand, forecasts production needs, and proposes batch adjustments.
- QA Officer: Verifies that changes in batch size do not affect product quality or stability.
- QC Analyst: Conducts required tests to ensure consistency across different batch sizes.
- Manufacturing Supervisor: Implements the approved batch size adjustments and documents changes.
4. Accountability
The Head of Production is accountable for ensuring that batch size adjustments follow GMP guidelines and maintain product quality standards.
5. Procedure
5.1 Reviewing Production Needs
- Assess demand fluctuations using sales forecasts and market analysis.
- Evaluate current production capacity and resource availability.
- Document production requirements in the **Batch Size Adjustment
Log (Annexure-1).**
5.2 Determining Batch Adjustment Parameters
- Identify allowable batch size variations based on equipment capacity.
- Ensure batch adjustments do not affect critical quality attributes (CQAs).
- Record planned adjustments in the **Batch Adjustment Plan (Annexure-2).**
5.3 Implementing Batch Adjustments
- Obtain QA and regulatory approval before modifying batch sizes.
- Communicate batch size changes to all relevant departments.
- Maintain documentation in the **Batch Adjustment Implementation Log (Annexure-3).**
5.4 Post-Adjustment Quality Control
- Conduct in-process and finished product testing for adjusted batches.
- Compare quality data with historical batch records.
- Document test results in the **Quality Verification Report (Annexure-4).**
