Andon systems, a legacy of the Toyota method, are experiencing a renaissance in Quebec factories thanks to technological advances that make them more accessible to manufacturing SMEs. These visual and audible alert systems enable a rapid response to production problems, significantly improving the reactivity and productivity of industrial facilities. By 2025, the adoption of these Andon solutions has become essential for Quebec manufacturing companies wishing to remain competitive in a demanding market.
The Andon system (a Japanese term meaning "lantern") originates from the Toyota Production System (TPS). You have probably already noticed those famous colored lights suspended in modern factories - they constitute the most recognizable visual element of this manufacturing alert system.
Originally, in Toyota's automotive assembly lines, the concept of Andon systems was simple but revolutionary: each worker had a cord to pull in case of a problem. This gesture activated a visual signal (typically green-yellow-red lights) indicating the location of the workstation in difficulty. A specialized team would then quickly intervene to solve the problem before it impacted the entire production.
This method represented a fundamental break from traditional approaches where workers had to leave their stations to find help, losing valuable time and often allowing problems to worsen.
Today, technological evolution has transformed these rudimentary Andon systems into sophisticated digital solutions. In Quebec factories, we are witnessing a true democratization of this Andon technology once reserved for large industrial groups.
Cords and mechanical signals have been replaced by touchscreen tablets installed at workstations. These digital Andon interfaces allow not only to signal a problem but also to qualify it precisely. For example, an operator can indicate that they are experiencing an issue with a label printer, which will automatically direct the alert to the IT team rather than general maintenance.
You may wonder how these Andon system alerts are transmitted? The possibilities are now multiple:
This last option is particularly interesting: some smart factories in Quebec assign a specific melody to each workstation, allowing supervisors to immediately identify the source of the problem, even without consulting a screen.
One of the most significant changes concerns the accessibility of these Andon systems for small and medium-sized manufacturing enterprises in Quebec. While traditional installations required costly and complex infrastructure, current visual alert solutions are much more affordable.
A standard tablet protected by an industrial case is now sufficient to equip a workstation. The value-effort ratio has become extremely favorable, even for multiple installations spread throughout the factory.
The configuration of these Andon systems can be as simple or sophisticated as necessary. A company can start with a basic system and then gradually evolve it by adding features such as:
The impact of Andon systems on the productivity of Quebec factories is multidimensional:
Increased responsiveness helps minimize downtime. When a problem occurs, it is quickly reported and addressed, avoiding the domino effect that can paralyze an entire production line.
A study conducted in several Quebec factories showed an average reduction of 37% in unplanned downtime after implementing a digital Andon system.
Unlike traditional systems, digital Andon solutions automatically generate valuable statistics:
These data transform the Andon system into a true continuous improvement tool. Teams can identify recurring problems and implement permanent solutions rather than simply reacting to incidents.
Supervisors and technicians no longer waste time looking for problems or being solicited for issues outside their expertise. The Andon system automatically directs alerts to competent personnel.
A manufacturer in Drummondville reported that its supervisors gained an average of 1.5 productive hours per day after installing an Andon system, time they could now devote to process improvement rather than crisis resolution.
Despite their obvious advantages, implementing Andon systems in Quebec factories presents some challenges:
The effectiveness of an Andon system relies on an organizational culture where reporting a problem is valued rather than perceived as an admission of failure. This cultural transition can be difficult in some traditional companies in Quebec's manufacturing sector.
To maximize their potential, modern Andon systems must often integrate with other solutions such as MES (Manufacturing Execution System) or ERP (Enterprise Resource Planning) systems, essential to Industry 4.0 in Quebec.
The future of Andon systems in the Quebec manufacturing context looks promising, with several emerging trends:
The next generations of Andon systems will likely incorporate artificial intelligence capabilities to anticipate problems by analyzing historical data patterns, thus strengthening the capabilities of smart factories in Quebec.
The Internet of Things (IoT) will allow machines themselves to trigger Andon alerts without human intervention, detecting performance deviations or early signs of failure.
Augmented reality solutions could visually guide technicians intervening on a problem signaled by the Andon system, further reducing resolution time in Quebec manufacturing plants.
Andon systems represent an accessible and effective productivity lever for Quebec factories of all sizes. Technological evolution has transformed these tools once reserved for industrial giants into affordable and flexible Andon solutions for Quebec manufacturing SMEs.
The impact on productivity is significant at several levels: reduction of downtime, improved responsiveness, collection of valuable data for continuous improvement, and optimization of human resources. The simplicity of implementing modern Andon solutions makes them a strategic investment for companies seeking to improve their performance.
In an economic context where operational efficiency is crucial for the competitiveness of Quebec companies, Andon systems constitute a judicious investment whose return quickly manifests in measurable productivity gains. If your manufacturing facility is looking to optimize its operations within the framework of Industry 4.0 in Quebec, adopting an Andon alert system could be your next step towards operational excellence.
