What Is Industry 4.0?

Industry 4.0 is the fourth industrial revolution, driven by integrating advanced digital technologies like the Internet of Things and automation. Unlike past revolutions, it focuses on creating smart, connected systems where machines, people and processes communicate seamlessly. These systems, often referred to as “smart factories,” are capable of self-optimisation, predictive maintenance and real-time data-driven decisions.

At its heart, Industry 4.0 transforms production by decentralising control. Machines can communicate and make autonomous decisions, reducing human intervention while increasing efficiency and quality. The shift allows manufacturers to optimise production lines, minimise waste and adapt rapidly to market changes.

The Industry 4.0 Definition

When asked to define Industry 4.0 and distil it down to be as easily understood as possible, Patrick, our lead engineer came up with the following Industry 4.0 meaning.

Industrial Revolutions Before Industry 4.0

Before Industry 4.0, three major industrial revolutions reshaped manufacturing and society. Each of these revolutions laid the foundation for Industry 4.0, with increasing levels of automation, efficiency and connectivity, culminating in today's advanced smart factories.

The First Industrial Revolution (late 18th century)

Marked by the introduction of mechanisation and steam power, the first industrial revolution, usually talked about as the Industrial Revolution, transformed traditional handcraft production into machine-based manufacturing. Innovations like the steam engine enabled factories to produce goods on a much larger scale, leading to mass production and the growth of industries such as textiles and mining.

The Second Industrial Revolution (late 19th to early 20th century)

This period saw the rise of electricity and assembly lines, further increasing productivity. Innovations such as the electric motor, telegraph and telephone enabled faster communication and greater industrial efficiency. Mass production techniques, such as those pioneered by Henry Ford's assembly line, allowed goods to be produced faster and at a lower cost.

The Third Industrial Revolution (mid-20th century)

Known as the digital revolution, this era introduced computers and automation into manufacturing. The development of electronics, programmable logic controllers (PLCs) and early automation systems allowed industries to automate repetitive tasks, improve precision and reduce human involvement in the production process.

The Technology Surrounding Industry 4.0

The success of Industry 4.0 hinges on several key technologies that are transforming how businesses operate and compete. Together, these technologies are driving the transformation of traditional manufacturing into a fully integrated, data-driven ecosystem where efficiency, flexibility and innovation are paramount.

Connectivity

One of the core components of Industry 4.0 is the ability for machines, devices and systems to connect and communicate in real time. Using technologies like the Internet of Things (IoT) and the cloud, data can flow seamlessly between different parts of the production process, enabling more efficient operations and faster decision-making across the entire supply chain.

Automation

Robots and Artificial Intelligence (AI) play a crucial role in automating tasks that traditionally require human input. These technologies reduce the chances of error, increase efficiency and allow machines to perform complex tasks autonomously. From robotic arms in manufacturing to AI-powered quality control systems checking PCBs, automation is a key driver of the fourth revolution.

Big Data Analytics

The vast amount of data generated by connected devices and automated machines requires innovation in processing and interpreting it. This is harnessed through big data analytics. By analysing this data in real-time, businesses can make informed decisions, predict equipment failures, optimise production processes and continuously improve performance. This data-driven approach enables smarter, more efficient manufacturing.

Smart Manufacturing

Fully automated smart factories are the epitome of Industry 4.0. These factories utilise AI and data to predict maintenance needs, automatically adjust workflows, switch production lines and optimise them all in real-time. This results in higher productivity, minimal downtime and the ability to customise production on the fly based on real-time demands of the wider marketplace.

Industry 4.0 Examples - Businesses Leveraging The Fourth Revolution

Many businesses across various industries have successfully adopted Industry 4.0 technologies, revolutionising their operations and gaining a competitive edge. These businesses demonstrate the real-world benefits of adopting Industry 4.0 technologies, from improved efficiency and reduced downtime to enhanced customisation and predictive maintenance. By leveraging the power of IoT, AI and big data, they have transformed traditional operations into intelligent, interconnected systems that drive continuous improvement.

Siemens (Manufacturing)

Siemens’ Amberg factory is a prime example of a smart factory. Using a combination of IoT, automation and AI, the plant operates with "all product, process and quality data for up to sixteen million Simatic products manufactured annually at the site are available at all times in real-time". This connectivity allows for precise control with the ambitious aim of reducing manufacturing defects to zero and enabling mass customisation without sacrificing efficiency.

Amazon (E-commerce/Warehousing)

Amazon has implemented automation and robotics in its fulfilment centres to streamline the picking and packing process. Robots move inventory around warehouses, while AI optimises the route for human workers, making operations faster and more efficient. The integration of data analytics also allows Amazon to predict product demand and manage its supply chain in real-time, ensuring faster delivery times and reduced costs.

Industry 4.0 vs. Industry 5.0

While Industry 4.0 focuses on the automation and digitisation of manufacturing through technologies like IoT, AI, and big data, Industry 5.0 shifts towards a more human-centric approach, where collaboration between humans and machines becomes central.

In this new phase, the goal is to merge the strengths of both automation and human creativity, promoting sustainable and personalised production processes, thus shifting the focus from pure efficiency to creating more personalised, eco-friendly products with a longer life-cycle. While Industry 4.0 aimed for smarter automation, Industry 5.0 brings humans back into the equation to drive innovation.
