When you think of quality control, you might think of simply checking for defects. However, quality control is much more than that. It’s about reliability, respect for the craft, and closing off the production cycle. It’s about laying the final stepping stones for progress and innovation – the cherry on top of the manufacturing cake. 

In the aviation industry, accurate quality control has been the catalyst for numerous breakthroughs. Innovations like composite materials, fly-by-wire technology, and highly efficient jet engines have taken flight, soaring the safety, performance, and efficiency of modern aircraft to new heights. These advancements not only enhance our current capabilities but also set the stage for future innovations. Imagine automated flight systems, cutting-edge materials and techniques, and more sustainable aviation practices. Quality control ensures that these advancements are not just dreams but reliable, safe realities ready to revolutionise how we fly.

Take the Hughes H-1 Racer, for instance. This iconic aircraft, the last privately-built plane to set a world speed record, embodies the power of meticulous quality control. Through painstaking attention to detail and rigorous testing, it achieved groundbreaking success, showcasing the incredible potential of thorough quality control.

The evolution of Quality Control

Our journey from Industry 1.0 to Industry 5.0 has been a remarkable evolution. Industry 1.0 introduced us to mechanisation, water, and steam power. Industry 2.0 brought mass production, assembly lines, and electrical energy. Industry 3.0 ushered in automation, computers, and electronics. Industry 4.0 introduced cyber-physical systems, IoT, and advanced networks. Now, Industry 5.0 emphasises mass customization and human-machine collaboration. Despite these technological leaps, traditional quality control methods lag behind, struggling to keep up with the pace of innovation.

The need for advanced technology

Traditional quality control faces significant hurdles; Human error and fatigue lead to high error margins, subjectivity creates inconsistent standards, and inefficiency results in wasted resources due to ineffective defect detection. These limitations highlight the necessity for advanced technology in quality control. AI and computer vision come to the rescue, offering precise, consistent, and fatigue-free inspections. They can identify defects invisible to the human eye, providing the reliability and accuracy needed to meet today’s high customer expectations.

Barriers and solutions to AI adoption in Quality Control

Despite its immense potential, AI adoption in quality control is not without its challenges. High-quality data is the lifeblood of AI, and without it, these systems are like engines without fuel. Collecting and maintaining accurate, comprehensive, and clean data can be resource-intensive and technically demanding. Fortunately, techniques such as automated data labelling and synthetic data generation can help create robust datasets with minimal or no manual labelling, streamlining the data preparation process.

Product variations introduce another layer of complexity. AI systems must contend with differences in size, shape, colour, and texture, particularly non-uniform surfaces that can be as unpredictable as a painter’s palette. This diversity often requires extensive training and meticulous fine-tuning of AI models to ensure they can interpret the variability and still deliver spot-on results. However, by leveraging pre-trained models that have been trained on vast amounts of diverse data, AI systems can effectively manage these variations and maintain high performance across different conditions.

Concerns about AI stability, reliability, and security cast a long shadow over its adoption. Businesses may be hesitant to fully embrace AI without assurances that these systems will perform reliably under all conditions. Security is also a major concern, as AI systems can be vulnerable to cyber-attacks that could compromise their functionality or the integrity of the data they use. Implementing robust cybersecurity measures, adhering to ISO-compliant protocols, and ensuring continuous monitoring can mitigate these risks and build confidence in AI systems.

Then there’s the human factor: the resistance to change. Employees and stakeholders, who have perfected their skills in traditional quality control methods, may view AI with scepticism, fearing job displacement or doubting the technology’s capabilities. Overcoming this resistance requires a thoughtful blend of education, reassurance, and clear demonstrations of AI’s tangible benefits. By showcasing how AI can rather augment human skills, boost job efficiency, and elevate overall quality, organisations can cultivate a more accepting and enthusiastic attitude towards AI integration. 

How to get started with AI in quality control

Strategic approaches are key to successful AI implementation in quality control. Here’s how:

• Start small with a Proof of Concept (PoC): “In theory, theory and practice are the same. In practice, they are not.” To bridge this gap, begin with a Proof of Concept (PoC) to test AI systems on a small scale. This approach allows you to evaluate the technology’s effectiveness without committing extensive resources upfront. Starting small not only helps identify potential issues early but also allows for necessary adjustments before a full-scale rollout, minimising risks and maximising success.

• Address regulatory barriers early on: Navigating the regulatory landscape is crucial for successful AI implementation in quality control. Engage with regulatory bodies early in the process to ensure your AI systems meet all necessary standards. This proactive approach minimises delays and facilitates a smoother implementation process. For instance, adhering to ISO standards for quality control management, FDA regulations for medical devices, and EU regulations for manufacturing helps ensure compliance and paves the way for seamless integration.

• Request system freeze capabilities: ​​Imagine being able to hit pause on your AI system, capturing it at its peak performance. System freeze capabilities let you do just that, ensuring consistent performance and thorough testing before rolling out updates. It’s a vital tool for troubleshooting and validating functionality in a controlled environment. For example, are you going to use a defect rate threshold of 1% or 2%? By setting consistent settings and metrics for a period of time, you achieve unified and precise decision-making, making sure everyone is on the same page.

• Conduct Measurement System Analysis (MSA): Like tuning a musical instrument, regular Measurement System Analysis (MSA) ensures that your AI model remains in perfect harmony over time. MSA involves a series of tests and evaluations to verify that your measurement systems are precise, accurate, and reliable. By conducting MSA, you can detect and correct any deviations or “drift” in the AI system’s performance. This meticulous process helps maintain the consistency and stability of your AI models, ensuring they continue to produce accurate results.

• Implement robust cybersecurity: Implementing robust cybersecurity measures is crucial to protect the integrity and quality of your AI systems. Safeguarding your training data is like fortifying a castle, preventing theft and ensuring consistent performance. By adopting ISO-compliant cybersecurity protocols, you create a moat and drawbridge that guard against potential threats. This fortress of security not only shields your valuable investment but also maintains the operational integrity of your AI models. With these defences in place, you can trust that your AI will deliver accurate and reliable results, enabling your organisation to navigate the digital landscape with confidence and peace of mind.

However, the success of advanced features like system freeze capabilities, regulatory compliance, measurement system analysis (MSA), and robust cybersecurity depends on seamless integration into current practices. Without this harmony, even the most sophisticated AI solutions can fall short of their potential.
