What a great time to be in Manufacturing!!!
THE 4 INDUSTRIAL REVOLUTIONS
Since Prometheus stole the fire of knowledge from right under the noses of the gods on Mount Olympus and bestowed it upon mankind, humans have not stopped fiddling with it and creating striking innovations all throughout their evolution.
Over the course of history, mankind has perfected its industry by not only relying on technical evolution but also by reinventing it as new resources have created new technical means. Therefore, industry has benefited from qualitative advancements which have sometimes been so ingrained in a certain time period and have had such an overwhelming impact that we have dubbed them “revolutions”. Sentryo would like to give you a quick look back in time at these first three industrial revolutions to define the contours of a fourth revolution which is taking shape right before our very eyes.
THE FIRST INDUSTRIAL REVOLUTION – 1765
Following a slow period of proto-industrialization, this first revolution spans from the end of the 18th century to the beginning of the 19th century. It witnessed the emergence of mechanization, a process that replaced agriculture with industry as the foundations of the economic structure of society. Mass extraction of coal along with the invention of the steam engine created a new type of energy that thrusted forward all processes thanks to the development of railroads and the acceleration of economic, human and material exchanges. Other major inventions such as forging and new know-how in metal shaping gradually drew up the blueprints for the first factories and cities as we know them today.
THE SECOND INDUSTRIAL REVOLUTION – 1870
Nearly a century later at the end of the 19th century, new technological advancements initiated the emergence of a new source of energy: electricity, gas and oil. As a result, the development of the combustion engine set out to use these new resources to their full potential. Furthermore, the steel industry began to develop and grow alongside the exponential demands for steel. Chemical synthesis also developed to bring us synthetic fabric, dyes and fertilizer. Methods of communication were also revolutionized with the invention of the telegraph and the telephone and so were transportation methods with the emergence of the automobile and the plane at the beginning of the 20th century. All these inventions were made possible by centralizing research and capital structured around an economic and industrial model based on new “large factories” and the organizational models of production as envisioned by Taylor and Ford.
THE THIRD INDUSTRIAL REVOLUTION – 1969
Nearly a century later, in the second half of the 20th century, a third industrial revolution appeared with the emergence of a new type of energy whose potential surpassed its predecessors: nuclear energy. This revolution witnessed the rise of electronics—with the transistor and microprocessor—but also the rise of telecommunications and computers. This new technology led to the production of miniaturized material which would open doors, most notably to space research and biotechnology. For industry, this revolution gave rise to the era of high-level automation in production thanks to two major inventions: automatons—programmable logic controllers (PLCs)—and robots.
The first industrial revolution used water and steam to mechanize production, the second used electric energy to create mass production and the third used electronics and information technology to automate production. Today a fourth industrial revolution is underway which builds upon the third revolution and the digital revolution that has been taking place since the middle of the last century. This fourth revolution with exponential expansion is characterized by merging technology that blurs the lines between the physical, digital and biological spheres to completely uproot industries all over the world. The extent and depth of these changes are a sign of transformations to entire production, management and governance systems.
