The platform also supports small and medium-sized companies in particular in overcoming the challenges of Industry 4.0.

The industrial revolution: 4 steps to Industry 4.0

It is no coincidence that machines can now communicate with each other via the internet and carry out complex processes automatically. People have always tried to simplify their work by using tools to improve processes and make them more efficient. In industry, this has taken place in four stages. Here is an overview of the evolution of the industrial revolution up to Industry 4.0 as we know it today:

• Industry 1.0 (late 18th century) — The invention of the steam engine began the mechanisation of production, replacing manual labour with machines. This laid the foundations for modern production processes and factories.
• Industry 2.0 (early 20th century) — The introduction of the assembly line and electrification revolutionised mass production, greatly increasing efficiency and scalability. Communication and information technology also improved the control and management of production.
• Industry 3.0 (1970s) — Automation through electronics, IT and the first robots optimised production processes. Digital control systems and robotics significantly increased efficiency and precision.
• Industry 4.0 (today) — Since the end of the 20th century, the Internet has grown in importance as a central technology in industry. Since 2011, the term ‘Industry 4.0’ has stood for increasing digitalisation and networking. The Internet of Things (IoT) and intelligent technologies such as artificial intelligence have played a key role in shaping digitalisation 4.0 in industry. Networked machines, machine learning (ML) and the digital twin enable intelligent, self-optimising production. This digitalisation 4.0 offers new opportunities and risks, as it makes processes more flexible and efficient, but also poses challenges in terms of management and IT security.
