Why MBWI is critical to quality on the manufacturing floor

Following the examination of MBWI within the context of Industry and Quality 4.0, this section will explore the crucial role it plays in empowering frontline workers to enhance quality outcomes. It will also feature insights from a comprehensive survey of 500 manufacturing executives responsible for managing products across the product lifecycle. These responses underscore the significant benefits of MBWI and illustrate the potential consequences of not adopting these essential tools.

Accelerating Training and Reducing Errors with Visual Learning

MBWI leverages highly visual content to accelerate training and deepen understanding among workers. Our survey respondents agreed. In fact, 80% indicated that the more visual the documentation, the quicker people are able to understand it.

Visual elements are particularly important for diverse workforces, where language barriers can impede understanding. On that note, 73% of respondents agreed that text-heavy instructions are difficult to follow due to differing first languages and varying levels of reading comprehension. By making the instructions highly visual, MBWI ensures that all workers, regardless of their linguistic background, can understand and execute their tasks accurately.

Enhancing Comprehension and Efficiency Through Multimodal Learning

In addition to visual learning, MBWI addresses auditory, linguistic, social, and solitary learning. MBWI accommodates different learning modalities by enabling the integration of multiple content formats within a single document, including interactive animations, text, images, diagrams, video, audio, and embedded 3D models. Not to mention, workers benefit from having all the information in one place, reducing the need to switch between documents, which can waste time and introduce errors.

Boosting Task Performance with Interactive Instructions

Interactivity, a key feature of the most advanced MBWI solutions, significantly enhances comprehension by enabling frontline workers to manipulate, explore, and visualize instructions in ways that static text or images cannot. Third-party research demonstrates that this interactivity leads to increased speed and reduced errors. For instance, workers using digitally animated, interactive work instructions performed tasks almost 20% faster and with 60% fewer errors on their first attempt compared to those using paper instructions. Remarkably, even by the fourth attempt, when both groups were more familiar with the process, the interactive group was still 13% faster and made 55% fewer errors than the paper group.

Ensuring Accuracy and Minimizing Misunderstandings with Precise Instructions

It’s not just interactivity that accelerates the process and reduces errors; it’s also the precision of the model itself. Our research shows that in the previous two years, 69% of respondents experienced negative impacts on projects or products at their companies due to errors or delays caused by inaccurate or unclear product/process documentation.

While the lack of clarity could stem from various factors, using the model as a foundation for understanding increases accuracy and minimizes misunderstandings. The consequences of inaccurate and unclear documentation are significant: 35% of respondents reported manufacturing errors and 38% encountered wastage due to defects.

Improving Documentation Accuracy and Efficiency by Streamlining Processes

You might wonder how benefits for document creators can lead to quality outcomes for frontline workers, but the impact is substantial. MBWI allows technical writers to produce detailed visuals without relying on engineers to do it for them, eliminating a common bottleneck. Removing this bottleneck not only streamlines the process, but also significantly improves the quality of outputs, directly benefiting frontline workers.

According to our respondents, 39% agreed that document quality and/or accuracy suffers as a result of time pressure to complete instructions. The impacts of delays can be several, including manufacturing errors (31%) and wastage due to product defects (39%). Moreover, 33% said lack of skills or software to work directly with 3D models caused bottlenecks in the documentation workflow, and 28% said delays were due specifically to obtaining visualizations from CAD engineers.

Maintaining Compliance and Minimizing Errors with Dynamic Updating

Model-based work instructions enable real-time updates directly from the model. Real-time updating is essential, as 69% of executives surveyed reported negative impacts on projects or products due to errors or delays from out-of-date documentation.
