Empowering All: Manual Work Meets Modern Automation

14th September, 2020

In spite of advancing digitalization, the following truth still applies: manual workstations remain indispensable in situations where automation struggles, particularly for products made in small quantities or with complex processes. Such workstations are preferred at the Martinshof Werkstatt Bremen – a workshop in Germany employing a mixed-ability workforce. The workshop serves as an ideal environment to integrate people with physical or cognitive handicaps into the workplace.

Diversifying the Workforce

Under the banner of "2030 Agenda for Sustainable Development," the UN has defined a set of different goals and objectives for realizing more sustainable growth in society; inclusive employment stands as the eighth goal in this Agenda. Here, the UN seeks to promote economic growth that is inclusive of all persons, as well as implement full and productive employment practices that allow individuals with disabilities unrestricted access to the job market. Mitsubishi Electric stands as one firm dedicated to fulfilling these social responsibilities, consistently striving to maintain a diversity- and inclusion-focused employment policy. It implements this both directly through hiring practices and through special initiatives such as MELCO Tender Mates, a subsidiary company that performs various production and service-related tasks, including, for example, producing baked goods for business/personal use and hospitality events.

Each workplace and industry plays a role in promoting inclusion, and the realm of manufacturing and automation is no different. Such workspaces can play a significant supporting role in not only improving manufacturing processes but also in actively diversifying employment practices and environments.

The Wisdom of Japan

Many have heard of Kaizen – but perhaps less well-known is the practice of Poka Yoke (pronounced po-ka-yo-kay). Poka Yoke has cemented a stable role in the Japanese manufacturing landscape for over 60 years, with roots in Japanese culture that extend back much further.

Poka Yoke translates quite simply as "error proofing," and when applied to manufacturing, it embodies a practice that eliminates mistakes and prevents omissions along the entire production line. Behind this tactic is a state of mind focused not only on improving production quality, but also on boosting productivity. Most of us take pride in a job well done – so anything that makes it easier to do a job better is a welcome addition.

Thanks to the Poka Yoke controller, existing technology, such as a digital torque wrench in this case, can easily be integrated into the error-free process with instructions fed to the operator via the GOT HMI.

Harmony Between the Digital and Real Worlds

It may seem counter-intuitive to apply traditional cultural practices in the modern digital manufacturing world, but the benefits well outweigh the sum of their parts. Workstations are one stage of such implementation; here, for example, Mitsubishi Electric’s Guided Operator Solutions (Poka Yoke) help manage component selection, smoothen operational procedures, and even provide visual guides for operators.

But it doesn’t stop there. With a digitalization process that Mitsubishi Electric calls e-F@ctory, stakeholders can now collect operational metrics and data and report this information back to manufacturing business systems – effectively streamlining the data collection and reporting process. One notable aspect of this system is that it allows for the incremental and scalable deployment of technology to support the manufacturing process (otherwise known as Kaizen), which makes these concepts and technologies accessible for businesses of all sizes.

A Unified Goal

Let’s now return to where we began: Martinshof Werkstatt in Bremen, Germany. Here, a team of mixed-ability workers produce vital parts and assemblies needed for manufacturers in the automotive industry. Implementing Poka Yoke processes here has empowered the staff members to feel more confident in what they do – not only reducing the amount of quality checks required, but also improving productivity. Another advantage of this technology is its accessibility: usable for a wider and more diverse workforce. This includes everyone from physically disabled staff to those with learning (reading/writing) disabilities as well as non-disabled staff. Everyone is equal and an important part of the team – and this technology is accessible to everyone.

"One of our goals is to support a wide range of human resources, including workers with disabilities," says Miriam Berger who oversees production planning at Martinshof Werkstatt. "To achieve this goal, it is essential that we create an environment where every employee can work smoothly and without stress."

In its endeavors towards accessibility, Martinshof has proven itself to be a role model in realizing a more diverse, opportunity-driven workplace. And Mitsubishi Electric hopes to continue serving both as a global partner and local friend in these efforts.
