What Is Industry 4.0, and What Technologies Are Driving It?

Since the end of the 18th century, we have experienced several different industrial revolutions. And now, we are in the midst of a major digital transformation in how products are made and how various technologies are automated. This revolution is called the Fourth Industrial Revolution, also known as Industry 4.0.

1. What Is Industry 4.0?

The Fourth Industrial Revolution, or Industry 4.0, has become one of the biggest buzzwords out there. To better understand Industry 4.0, we need to look back at history.

The first industrial revolution began in the 1770s, marking a shift from hand labor to machines and from farms to the first factories. Innovative technologies such as the flying shuttle, the water frame, and the power loom made weaving cloth and spinning thread far more accessible. Cloth production became faster, took less time, and required fewer workers.

About 100 years later, the second industrial revolution brought electricity and assembly lines, leading to factories much like the ones we see today. Factories expanded on a massive scale, and people's lives came to be governed by the clock rather than the sun — a tremendous change.

The third industrial revolution, the digital revolution, began in the 1970s. This era witnessed the digitization and automation of electronics and computers. It was also marked by the invention of the internet and the discovery of nuclear power.

2. The Evolution of Industry From 1.0 to 4.0

Before exploring the "what," "why," and "how" of Industry 4.0, it helps to first understand how manufacturing has evolved since the 1800s. The industrial revolutions the world has experienced, or continues to experience, fall into four phases.

2.1. The First Industrial Revolution

The first industrial revolution took place from the late 1700s to the early 1800s. During this era, manufacturing evolved from manual labor by people and animals to a more optimized form of human labor through the use of water- and steam-powered engines and other types of machine tools.

2.2. The Second Industrial Revolution

In the early 20th century, the world entered the second industrial revolution with the introduction of steel and the use of electricity in factories. The introduction of electricity made manufacturing more efficient and helped increase the mobility of factory machinery. During this period, mass production concepts such as the assembly line were introduced as a way to boost productivity.

2.3. The Third Industrial Revolution

Starting in the late 1950s, the third industrial revolution gradually took hold, bringing electronic and, eventually, computer technology into factories. This marked the beginning of a shift from analog and mechanical technologies to digital technologies and automation software.

2.4. The Fourth Industrial Revolution, or Industry 4.0

In recent decades, the fourth industrial revolution, known as Industry 4.0, has been emerging. Industry 4.0 takes the digital technologies that have been emphasized in recent decades to a whole new level through interconnectivity via the Internet of Things (IoT), access to real-time data, and the introduction of cyber-physical systems.

Industry 4.0 offers a more comprehensive, interconnected approach to manufacturing, bridging the physical and digital worlds and enabling better collaboration across departments, partners, vendors, products, and people. Industry 4.0 lets leaders better control and understand every aspect of operations, using real-time data to boost productivity and drive growth.

3. Technologies Driving Industry 4.0

The Fourth Industrial Revolution and Industry 4.0 essentially refer to the same concept, but they are sometimes used in different contexts.

The Fourth Industrial Revolution is a concept proposed by the World Economic Forum, representing the idea that modern technological innovation will bring revolutionary change to the economy, society, and industry. It is underpinned by rapid advances in fields such as information technology, robotics, artificial intelligence, and biotechnology, and is characterized by the fusion of the digital and physical worlds, human-technology interaction, and the growing importance of data.

Industry 4.0 is a concept within the Fourth Industrial Revolution that focuses specifically on manufacturing. Proposed by the German government, it refers to advancing digitalization and automation in manufacturing, leveraging technologies such as the IoT, big data, cloud computing, and artificial intelligence to automate and optimize manufacturing processes. The goal is for equipment and systems to work together, sharing data in real time to boost productivity and efficiency.

In other words, the Fourth Industrial Revolution is a concept referring to broad economic and social transformation, while Industry 4.0 represents concrete efforts around digitalization and automation in manufacturing within that broader shift. That said, the two overlap, and Industry 4.0 is generally positioned as part of the Fourth Industrial Revolution.

We know that digitalization and automation of value chain processes are important across several fields. Let's go over the key areas you should know about.

3.1 IoT (Internet of Things)

Big data analytics, starting with the IoT (Internet of Things), means collecting massive amounts of real-time data. In an industrial setting, this data can be gathered from resource planning, customer relationship management, production line data, supply chain information, delivery processes, and more. When applied to real-time analysis, it provides insights for better decision-making, which is why it plays such an important role in Industry 4.0.

3.2 Industrial Internet of Things (IIoT)

The Industrial Internet of Things (IIoT) applies sensor suites to robots, machinery, and equipment to collect a wide range of real-time data. Analyzing this data lets industries optimize productivity, minimize downtime, and track customer behavior.

3.3 3D Printing

3D printing is mainly used for prototyping and direct tooling. There are also several cases where 3D printing is used with more durable materials, such as titanium, steel, and aluminum — repairing gas turbine compressor blades is one example. The cost of metal parts made with 3D printers is currently high, but it is shrinking rapidly.

3.4 Autonomous Machines

Autonomous machines can minimize human intervention in programming, assembly, testing, inventory management, delivery, and more. Software is rapidly becoming more sophisticated while also becoming more user-friendly. For example, robots are beginning to create their own control software based on operator input. In consumer products, examples include automotive collision avoidance and lane-keeping control.

3.5 Digital Twin

A digital twin is a virtual model designed to mirror a physical object, used for internal design, simulation, and design reviews. Once the entire structure becomes model-based, any digital twin can be extracted easily. The digital world may always be accurate and perfect, but the real world isn't, so discrepancies between design and construction must be accounted for — and digital models help with simulation and corrective action.

3.6 Cybersecurity

In Industry 4.0, most company assets are digital, and cloud storage increases exposure and risk. Operational digital failures are a real concern, which is why IT security is essential. Robustness becomes the keyword, with continuous development to protect digital assets.

3.7 Augmented Reality (AR)

Augmented reality (AR) overlays digital data onto the natural environment and forms the core of Industry 4.0. Outside industry, AR is mainly used for gaming; in industry, video tools are commonly used for knowledge transfer, troubleshooting, inspection, and training. Smart glasses are an essential AR element for when operators need both hands free, though phones and tablets can often achieve the same result by pausing the video stream.
