The Benefits of a Technical Audit

Investing in a technical audit might seem like an extra cost in the production process, but in reality, it might save you from a lot of troubles and costly reworks down the line. Here are some the benefits of a Technical Audit:


  • Quality Confidence: An in-depth Manufacturing audit helps you identify potential quality risks before they become costly nightmares, ensuring garments that are as flawless as your brand image.

  • Compliance: Technical audits ensure your garments comply with all relevant safety and regulatory standards, protecting you from legal headaches and keeping your brand squeaky clean.

What Makes a Technical Audit Great?

Sure, ticking boxes is a good start, but a truly great technical audit goes beyond the checklist. It’s a collaborative journey towards achieving excellence in your garment production chain, offering valuable insights beyond just compliance. 


Here are some key ingredients that make a technical audit truly great:


A Collaborative Mindset:

  • Shifting from “inspection” to “partnership”: Great audits foster open communication and teamwork between auditor and supplier, focusing on mutual improvement rather than fault-finding.
  • Collaborative action plans: Effective audits involve the supplier in developing actionable steps to address identified issues, ensuring commitment and ownership.
  • Beyond the checklist: Great auditors go beyond ticking boxes, asking probing questions, understanding the supplier’s context, and tailoring recommendations to their specific needs.

Depth and Insight:

  • Hands-on approach: Great audits delve deeper than just documentation, observing actual practices, interviewing personnel at all levels, and uncovering potential hidden risks.
  • Data-driven analysis: Utilizing objective data from interviews, observations, and testing strengthens the audit’s credibility and provides concrete evidence for recommendations.
  • Risk assessment: It involves going beyond identifying issues to assess their potential impact and prioritize recommendations based on severity and likelihood.

Sustainability and Long-Term Impact:

  • Focus on continuous improvement: Great audits don’t end with a report; they establish a framework for ongoing monitoring and collaboration, ensuring consistent progress towards quality goals.
  • Building supplier capacity: One of the key purposes of a technical audit is to equip suppliers with tools and knowledge to improve their own quality management systems and build long-term sustainability.
  • Positive ripple effect: It helps contribute to a wider positive impact by promoting ethical practices, environmental responsibility, and improved industry standards throughout the supply chain.

Professionalism and Credibility:

  • Qualified and experienced auditors: Great audits are conducted by qualified professionals with expertise in the garment industry and relevant certifications.

Objectivity and transparency:o  A neutral and unbiased approach, clearly communicating findings and recommendations without personal agendas allows you to find out any inefficiencies in your supply chain

When to Conduct a Technical Audit on Your Suppliers

There’s no magic number for how often you should audit your suppliers. It depends on trust, risk tolerance, and the complexity of your production. But here are some general guidelines:


  • New Suppliers: Before you entrust them with your precious brand, it’s a good idea to conduct a technical audit to verify their process and prowess. This is your chance to assess their capabilities and mitigate potential risks before they become costly headaches.
  • Existing Suppliers: At least once a year. Consider it a quality checkup, ensuring they’re still meeting your standards and identifying areas for continuous improvement.
  • Red Flags: If you suspect quality issues or production inconsistencies, don’t wait for the next scheduled audit. A technical audit can be your emergency flare, illuminating the problem and guiding you towards a solution.

How to Conduct a Technical Audit

Conducting a successful technical audit in the garment industry requires a well-defined approach and attention to detail. Here’s a comprehensive guide to the key steps involved:


1. Preparation:

  • Define Your Goals and Scope: What are you hoping to achieve through the audit? Is it a new supplier evaluation, assessing specific product lines, or verifying compliance with regulations? Clearly defining your goals will help tailor the audit’s scope and ensure efficiency.
  • Choose the Right Auditor: Opt for an experienced and qualified professional with expertise in the garment industry and relevant international standards like ISO 9001 and SA8000.
  • Gather Information: Provide the auditor with relevant details about your company, product specifications, and any specific concerns you have regarding the supplier.
  • Review Documents: Obtain essential documents like the supplier’s QMS manual, factory layout plans, and production process flowcharts for better understanding.

2. On-Site Audit:

  • Factory audit: Walk through the production facility, observing working conditions, machinery, and overall cleanliness. Assess compliance with safety regulations and environmental standards.
  • Document Review: Verify certifications, test reports, and quality control records provided by the supplier. Ensure proper documentation and record-keeping practices.
  • Interviews: Conduct interviews with key personnel at different levels, including management, production supervisors, and quality control inspectors. Understand their roles, responsibilities, and knowledge of quality procedures.
  • Sampling and Testing: Depending on your needs, select product samples for independent testing to confirm material composition, performance, and compliance with safety standards.

3. Assessment and Reporting:

  • Data Analysis: The auditor will analyze all collected information, including observations, interviews, and test results, to assess the supplier’s strengths and weaknesses against the pre-defined criteria.
  • Audit Report: The auditor will produce a comprehensive report outlining the findings, identified gaps or non-conformances, and recommendations for improvement.
  • Corrective Action Plan: Collaborate with the supplier to develop a concrete action plan to address the identified gaps and ensure compliance with your requirements. Set timelines and responsibilities for implementing the plan.

4. Follow-up and Monitoring:

  • Schedule follow-up audits: Depending on the severity of non-conformances, revisit the supplier at predetermined intervals to assess progress and verify the implementation of the corrective action plan.
  • Maintain open communication: Foster ongoing communication with the supplier to address any arising issues and build a stronger, more transparent relationship.
