The Path to Quality Transformation: Assessing and Advancing Digital Maturity

Quality 4.0, situated at the intersection of quality management and digital transformation, is described as the integration of quality management practices within a digitally transformed landscape (Fadilisari et al, 2024). It leverages the advanced technologies of Industry 4.0, yet goes far beyond the mere adoption of technology. Quality 4.0 represents a comprehensive quality transformation, encompassing the adoption of processes and practices that support and empower people. Achieving this transformation requires assessing organizational, strategic, and digital maturity to prioritize initiatives and investments effectively.  

The task is large and the considerations many, yet early Quality 4.0 adoption rates have been encouraging. As of 2021, 56% of manufacturers were already engaged in or in the pilot stages of implementing Quality 4.0, according to LNS Research. Perhaps more telling of the true complexity though, is that more recent adoption rates are hard to come by, and in 2024, research papers have started to appear that suggest the path for implementing Quality 4.0 isn’t that obvious or easy. For example, these papers include the first ranking of implementation challenges and the first cohesive framework for readiness assessment and implementation.  

This blog will provide an introductory guide to the comprehensive framework presented in the latter paper, The Quality 4.0 Roadmap: Designing a Capability Roadmap Toward Quality Management in Industry 4.0 (Carvalho et al., 2024). The roadmap outlines the considerations for a seamless transition to enhanced quality management on the manufacturing floor and across the organization. By following this framework, manufacturers can systematically assess their current state, identify areas for improvement, and plan their journey toward quality transformation.

The Quality 4.0 capability roadmap: a broad organizational scope

The Quality 4.0 Roadmap is structured by two main dimensions: organizational domains and a range of maturity stages for each. Organizational domains encompass key functional areas such as quality management, product development, operations, strategy, and training, ensuring that all aspects of the organization are considered, and highlighting that quality transformation is much more than implementing the latest digital tools.  

Specifically, there are three organizational domains detailed in the roadmap:  

1. Value Chain and Operations: Focuses on integrating customer needs, ensuring product and service quality, and optimizing processes to enhance efficiency and deliver greater value.
2. Strategy and Organization: Emphasizes aligning quality initiatives with organizational goals, integrating quality management across departments, and fostering continuous improvement and innovation.
3. People and Culture: Involves empowering employees in adapting to new roles, cultivating a culture of quality and continuous improvement, and ensuring strong leadership commitment to quality initiatives.  

Addressing each of these areas across an organization ensures a comprehensive, holistic approach to quality transformation, a requirement for achieving sustainable excellence.  

The Quality 4.0 capability roadmap: from readiness to maturity

The maturity dimension of the Quality 4.0 capability roadmap is split into six stages: three stages of readiness followed by three stages of maturity. Each stage is marked by a particular theme, which includes specific requirements that must be satisfied before progressing to the next stage. The progression of themes is much like the levels in Maslow's hierarchy of needs, where foundational needs must be met before focusing on higher-level aspirations. For example, meeting requirements for stakeholder interactions, both within and beyond the organization, is essential before progressing in earnest to subsequent themes like process integration and digitization.  

Once a theme is introduced, an organization will need to continue iterating on it in future stages until a full quality transformation is achieved. For example, during the subsequent phase of digitization, the task for stakeholder interactions will involve ensuring these interactions are digitized, often with a dedicated digital platform to support them.  

The six maturity stages of the Quality 4.0 capability roadmap are detailed below:

Readiness

• Stakeholder Interaction: Characterized by limited and ad hoc interactions with customers, suppliers, and internal stakeholders, focusing on basic communication and initial feedback collection.
• Process Integration: Early stages of integrating processes across the organization, often involving manual processes and limited coordination between departments.
• Digitization: Beginning to transition from manual to digital processes, with initial adoption of digital tools and platforms for basic data collection and analysis.

Maturity

• Automation: Implementing advanced automation technologies to reduce manual intervention, enhance precision, and increase productivity in quality management processes.
• Connectivity: Establishing seamless connectivity between systems, machines, and stakeholders through IoT and other digital technologies to enable real-time monitoring and collaboration. For example, integrating model-based work instructions with MES and PLM systems can facilitate real-time logging of worker activities for compliance and dynamically update changes to the model across documentation.  
• Intelligence: Utilizing advanced analytics, artificial intelligence, and machine learning to derive insights from data, predict quality issues, and drive proactive and informed decision-making.

By detailing each stage of the quality transition, from initial readiness to advanced maturity, the roadmap enables a properly sequenced approach to achieving Quality 4.0, ensuring a solid foundation for each subsequent activity and ongoing organizational and stakeholder alignment.

Best practices for quality transformation

Now that you understand the outlines of the Quality 4.0 roadmap, there are several best practices the authors suggest that are designed to help organizations navigate the complexities of quality transformation. These practices aim to ensure that organizations build a strong foundation for achieving Quality 4.0 by overcoming common challenges, avoiding pitfalls, and aligning their efforts with broader organizational goals.

The best practices are derived from a combination of expert insights, practitioner experiences, and thorough research, including a comprehensive review of the existing literature. This blend of theoretical knowledge and practical experience ensures that the guidelines are both actionable and grounded in real-world application.

Here are the key best practices to guide your implementation process:

1. Bring stakeholders into the effort: Engage key stakeholders from the outset of the roadmap process, as their input is crucial for accurately assessing your organization’s readiness and maturity. Management plays a critical role in leading this effort, setting the tone for an organizational and cultural shift, fostering cross-functional collaboration, and ensuring alignment across teams—not to mention driving specific tasks that will support empowered connected workers.  
2. Assess and understand your starting point: Begin by accurately assessing your organization's current state of readiness and maturity across organizational domains. Look at existing capabilities, processes, and cultural readiness to identify the starting point within each domain.
3. Tailor the roadmap to your context: Once the starting point is identified, adapt the roadmap to fit your organization's specific context. This means considering industry-specific requirements, the scale of operations, customer expectations, supplier technologies, and the organizational culture. A customized approach ensures that the roadmap is relevant and actionable.
4. Build a strong foundation before advancing: Focus on fully stabilizing and mastering each stage before moving on to the next. For example, even if your organization has already digitized certain types of interactions and processes, fill any gaps in stakeholder interactions and then process integration before continuing to digitize. This sequential approach helps prevent rushing and ensures that each stage is built on a solid foundation.
5. Use feedback loops to guide progress: Implement feedback mechanisms at each stage to monitor progress, identify issues, and make necessary adjustments. Regular reviews help keep the roadmap on track and aligned with organizational goals.
6. Maintain organizational and stakeholder alignment: Continuously align the roadmap with both organizational goals and stakeholder expectations. Regular communication and updates help ensure that everyone remains committed to the shared vision.

These best practices offer clear guidance to support your Quality 4.0 journey. By applying them conscientiously, you can ensure that your organization is well-prepared for each step of the transformation.
