Advantages and Disadvantages of Automation

Automation is a key part of what is heralded as “Industry 4.0”, or the Fourth Industrial Revolution. Through a combination of smart machines, control systems, and automation tools, manufacturing operations are able to function more independently, with various steps in the process communicating with each other and process data informing computer system decisions in real-time.[3]

Whenever we talk about a new manufacturing or industrial framework, there are two sides to the story. Automation, particularly integrated automation, represents a massive paradigm shift in manufacturing that has many people feeling very optimistic and many feeling quite anxious. It’s important to look at both sides to understand where the benefits and disadvantages lie, and how to address them.

Advantages:

  • Productivity: One of the main reasons that manufacturers are investing increasingly in automation is because it can unlock higher productivity rates. With automation, tasks throughout the production chain—or the chain as a whole—can operate independently and with greater efficiency. 

  • Consistency: With automated technologies in place, manufacturers can benefit from greater process consistency thanks to in-depth process monitoring data. A lower reliance on human labor also minimizes the risk of human error in the production process.

  • Labor: This is admittedly a tricky one (you’ll also find it in the disadvantages section). There are benefits for both employers and employees when it comes to industrial automation. For one, automation enables manufacturers to mitigate the effects of labor shortages, particularly for skilled technicians. They can keep up production rates and even scale without having to seek out and hire additional workers. For another, automation eliminates the need for humans to undertake many tedious, repetitive tasks. This creates more space for more complex and valuable tasks that require problem solving, such as product development, process supervision, and big-picture strategizing. 

Disadvantages:

  • Cost: While there are long-term cost benefits for integrating automation in production workflows, the transition to automation and Industry 4.0 comes with a significant initial cost due to the high price of automated equipment and software tools. This cost can be prohibitive to smaller producers, and may only be viable for large manufacturing companies. 

  • Labor: On this side of things, automation threatens existing labor forces and can lead to worker displacement. If a whole segment of jobs is suddenly automated, those workers are at risk of losing their employment and their skills may be devalued. Upskilling and trainings are an important strategy for mitigating this effect. They equip workers for new roles and give them new skills that are in demand.

  • Cybersecurity: As processes across manufacturing become more connected, they become more efficient but they also increase their vulnerability to cyber attacks. Malware, ransomware, and data breaches can compromise business processes significantly and come with a high cost. Establishing a robust cybersecurity system can help to minimize these risks and keep IP and production chains safe as automation is implemented.
