Quality 4.0

Quality Glossary Definition: Quality 4.0

Also called: Industry 4.0, digital transformation

Technological advances of the past decade have resulted in a new industrial revolution often referred to as the fourth industrial revolution or "Industry 4.0." It’s a revolution driven by the exponential growth of disruptive technologies and the changes those technologies are bringing to the workplace, the workforce, and the markets organizations serve.

"Quality 4.0" is a term that references the future of quality and organizational excellence within the context of Industry 4.0. Quality professionals can play a vital role in leading their organizations to apply proven quality disciplines to new, digital, and disruptive technologies.

The Evolution of Quality 4.0

During the first industrial revolution (late 1700s and early 1800s), innovations in steam and water power made it possible for production facilities to scale up and expand potential production locations. Before then, manufacturing facilities had to be constructed along rivers so waterwheels could be used to generate power.

By the late 1800s, the discovery of electricity and development of infrastructure enabled engineers to build machinery for mass production. Iron ore production increased, enabling machines themselves to be mass produced. In the United States, the expansion of railways made it easier to obtain supplies and deliver finished goods.

The widespread availability of reliable power sparked a renaissance in computing. Toward the end of World War II—around the time when ASQ (then ASQC) was formed—digital computing started to emerge from its analog roots, first with mainframes, then client-server computing and PCs, followed by the advent of the internet and early e-commerce sites. The third industrial revolution came at the end of the 1960s with the invention of the programmable logic controller. This made it possible to automate processes, such as filling and reloading tanks, turning engines on and off, and controlling sequences of events based on the state of the process and changing environmental conditions.

Mobile devices and cloud computing led to a convergence of services, as multiple customer touch points (phone, fax, web, and tablets) gradually blended into the single view of the customer that most organizations now have. Just 20 years ago, organizations were barely able to link your phone calls to customer service, emails and web form queries. Now, it’s taken for granted.

The first industrial revolution was characterized by steam-powered machines, and the second by electricity and assembly lines. Innovations in computing and industrial automation defined the third. The fourth industrial revolution brings us machine intelligence, pervasive computing, affordable storage and robust connectivity (Figure 1).

Establishing and Implementing Quality 4.0 Principles

To achieve excellence through quality is to embrace the future of quality. It is paramount that quality professionals help their organizations make the vital connection between quality excellence and their ability to thrive in disruption, using quality principles to enable transformation and growth.


Quality 4.0 is more than technology. It’s a new way for quality professionals to manage quality with the digital tools available today and understanding how to apply them and achieve excellence through quality. By speaking the digital language and making the case for quality in disruption, quality professionals can elevate their role from enforcers to navigators to successfully guide organizations through digital disruption and toward excellence.


As more work is automated the need for flawless processes remains the same, if not more important. Existing processes will be broken and the need to educate the next generation of workers to implement new processes and strategies will be vital to not only the quality professional but also business operations. Quality is a vital link and should be included at the strategic level for sustainability during digital transformation.


Technology is growing 10 times faster than it used to, and organizations’ platforms, such as processes, systems, data, operations and governance, must keep pace. Technology also is a great leveler because it gives any individual with the right idea and intent the capability that previously was available only to large organizations. Quality professionals must move from data analyst roles to data wrangler roles by engaging with new technologies, understanding these technologic advancements and the potential outputs they create, and determining how and when to use them.

Quality 4.0 Tools

Deploying an organization’s digital strategy won’t be without hiccups. There will be some common challenges that cut across all industries and digital maturity levels, and others that are specific to an organization. In addition to the timeless and well-known quality tools and principles, the Quality 4.0 tools below should be leveraged to alleviate these challenges when implementing and deploying systems to support digital transformation.

  • Artificial intelligence: computer vision, language processing, chatbots, personal assistants, navigation, robotics, making complex decisions.
  • Big data: infrastructure (such as MapReduce, Hadoop, Hive, and NoSQL databases), easier access to data sources, tools for managing and analyzing large data sets without having to use supercomputers.
  • Blockchain: increasing transparency and auditability of transactions (for assets and information), monitoring conditions so transactions don’t occur unless quality objectives are met.
  • Deep learning: image classification, complex pattern recognition, time series forecasting, text generation, creating sound and art, creating fictitious video from real video, adjusting images based on heuristics (make a frowning person in a photo appear to smile, for example).
  • Enabling technologies: affordable sensors and actuators, cloud computing, open-source software, augmented reality (AR), mixed reality, virtual reality (VR), data streaming (such as Kafka and Storm), 5G networks, IPv6, IoT.
  • Machine learning: text analysis, recommendation systems, email spam filters, fraud detection, classifying objects into groups, forecasting.
  • Data science: the practice of bringing together heterogeneous data sets for making predictions, performing classifications, finding patterns in large data sets, reducing large sets of observations to most significant predictors, applying sound traditional techniques (such as visualization, inference and simulation) to generate viable models and solutions.

Quality 4.0 Value Propositions

New technology should always be introduced with a clear articulation of the desired benefits it will deliver and, sometimes, how it will happen. Value propositions for Quality 4.0 initiatives fall into six categories, listed in order of significance:

  1. Augment (or improve upon) human intelligence.
  2. Increase the speed and quality of decision making.
  3. Improve transparency, traceability, and auditability.
  4. Anticipate changes, reveal biases, and adapt to new circumstances and knowledge.
  5. Evolve relationships, organizational boundaries, and concept of trust to reveal opportunities for continuous improvement and new business models.
  6. Learn how to learn by cultivating self awareness and other awareness as skills.

Quality professionals are perfectly positioned to propose and lead digital transformation initiatives because they have deep skills in:

  • Systems thinking
  • Data-driven decision making
  • Leadership for organizational learning
  • Establishing processes for continuous improvement
  • Understanding how decisions affect people: lives, relationships, communities, well-being, health, and society in general

ASQ and BCG Quality 4.0 Study

In 2018, Boston Consulting Group (BCG) invited ASQ to partner in a study exploring Quality 4.0, focused primarily on the manufacturing sector in the U.S. and Germany. The study sought professionals’ perceptions of skills needed to implement Quality 4.0, obstacles to implementing, and cases for the use of digital quality management.

The study responses revealed five key themes:

  1. Only 16% of organizations surveyed have implemented Quality 4.0 initiatives, and 63% have not started planning (Figure 3).

  5. 69% of organizations plan on worker upskilling, with data analytics identified as the largest expertise delta.

Start Fast, Design for Scale

In the journey towards implementing Quality 4.0 initiatives, the ASQ-BCG study recommends that organizations should start fast and design for scale (Figure 6):

  1. Look at your pain points—where are you having issues in your processes and procedures?
  2. Ideate opportunities around these pain points and then prioritize them—where do you think you’re going to get the most value with some of these new technologies?
  3. Define and implement on a small scale—at headquarters via dashboards, at a pilot plant, etc.
  4. See if you get proof of concept and return of investment.
  5. If yes, take your detailed roadmap and go to scale, implementing the initiative across the entire organization.
