Certified Maintenance & Reliability Professional (CMRP) Practice Exam

Which of the following is NOT a component of the industrial revolutions?

1. Industry 1.0 - Mechanical tools

2. Industry 2.0 - Manual crafting

3. Industry 3.0 - Automated systems

4. Industry 4.0 - Smart technology

The correct answer is: Industry 2.0 - Manual crafting

The correct response is the indication that manual crafting does not fit within the framework of the industrial revolutions as defined. Each of the industrial revolutions represents a significant shift in production processes and technology. The first industrial revolution, marked as Industry 1.0, involved the transition from hand production methods to the use of mechanical tools, primarily driven by steam power. This revolution fundamentally changed manufacturing processes through mechanization. Industry 2.0, on the other hand, is characterized by mass production and assembly lines but is heavily based on mechanized processes rather than manual crafting. This phase introduced improved manufacturing techniques and efficiency, enabling the production of goods at a larger scale. In Industry 3.0, the introduction of automated systems showcased a significant technological advancement where machines began to take on more of the production roles, utilizing electronics and information technology. This focused on increasing efficiency and production rates through automation. Finally, Industry 4.0 introduces smart technology, which incorporates cyber-physical systems, the Internet of Things (IoT), and artificial intelligence to create interconnected, intelligent manufacturing processes. The term manual crafting is more representative of artisanal production and does not align with the mass production or technological advancements emphasized in the industrial eras, making it the option
