The industrial revolution has gone through several phases, each marked by technological advances that have transformed the fabric of production and management. In this article, we explore what Industry 4.0 and Industry 5.0 are, their key differences, and how process automation and AI are reshaping the future of manufacturing.
(If you are looking for a full, detailed explanation of Industry 5.0 alone, we have a post dedicated to that: What is Industry 5.0?. Here we focus on the differences between both eras.)
What is Industry 4.0?
Industry 4.0, also known as the fourth industrial revolution, is the name given to the era of automation and data exchange in manufacturing technologies. The term is not generic: it originated from the project "Industrie 4.0", presented by the German government at the Hanover Fair in 2011, as part of its high-tech strategy to maintain the country's industrial competitiveness.
It incorporates concepts such as the Internet of Things (IoT), cybersecurity, and Big Data. The key to Industry 4.0 is the "smart factory", where cyber-physical systems monitor plant processes and make decentralised decisions, with the machine and data at the core of the process.
What is Industry 5.0?
Industry 5.0 goes a step further, placing emphasis on collaboration between humans and intelligent machines. Unlike 4.0, which focuses on technology, 5.0 focuses on the coexistence of humans and robots in the workplace, seeking personalisation at scale and a sustainable approach in production processes. The European Commission formalised the concept in January 2021 on three pillars: human-centric, sustainable, and resilient.
Key differences between Industry 4.0 and 5.0
The main difference between the two is where the centre of the process is placed: the machine and data in 4.0, the human being in 5.0.
Industry 4.0 | Industry 5.0 | |
|---|---|---|
Origin | German government project, 2011 | European Commission, January 2021 |
Centre of the process | The machine and data | The human being |
Main objective | Automation and efficiency | Human-machine collaboration and well-being |
Key technologies | IoT, Big Data, cybersecurity, cyber-physical systems | The same as 4.0, plus collaborative AI and cooperative robotics |
Production type | Mass and standardised | Personalised, without losing efficiency |
Role of the human | Supervises the automated system | Actively collaborates with the machine, brings judgment |
Added priority | None beyond efficiency | Sustainability and resilience |
While 4.0 focuses on automation and efficiency, 5.0 introduces artificial intelligence and automation to work alongside people, not in their place, enhancing creativity and flexibility in production. In Industry 5.0, human expertise guides machine precision to achieve more personalised and well-being-oriented results.
It is important to understand that 5.0 does not replace 4.0, it is built on top of it. Without the foundation of automation, data, and connectivity provided by 4.0, there would be nothing upon which to apply the human judgment proposed by 5.0.
The start of Industry 5.0
Many companies are still in the early stages of full adoption of Industry 4.0, yet Industry 5.0 is already beginning to take shape. Its adoption is anticipated to be gradual, as companies start to value the importance of personalisation and sustainability as much as mass, standardised production.
How Rely fits into this transition
Rely, our AI-powered software that traces and automates industrial visual processes, fits naturally into this bridge between both eras: it delivers the automation characteristic of Industry 4.0 (data, traceability, cyber-physical inspection systems), while leaving final judgment in the hands of the quality team, which is precisely the principle championed by Industry 5.0. You can see how we apply it across different sectors in our use cases.
Frequently asked questions
Can a company be in Industry 5.0 without having completed 4.0?
In practice, not entirely. 5.0 requires the foundation of data, sensors, and automation provided by 4.0 in order to apply human judgment to something already digitalised.
Is Industry 5.0 only for large manufacturers with big budgets?
No, the principles (human-centricity, sustainability, resilience) apply to any company size. What changes is the scale and pace of adoption, not the concept.
What is the most practical difference between the two for a plant today?
In 4.0, the objective is to automate and collect data. In 5.0, in addition to that, a business actively decides which tasks the system leaves in human hands and why, rather than automating as much as possible by default.
How long does it take to move from 4.0 to 5.0?
There is no fixed timeframe: it depends on how much automation the plant already has. Companies with solid 4.0 foundations can start applying 5.0 principles almost immediately.
Conclusion
Industry 4.0 laid the foundations: connected machines, real-time data, automated processes. Industry 5.0 does not replace it, but completes it: it puts the human being back at the centre of that entire digitalised process, with sustainability and resilience as objectives just as important as efficiency. Understanding this difference is not just a theoretical exercise: it determines which questions you ask before automating your plant's next process.
