Definitions of Product Quality Different Approaches to Quality

Your Quality is solely determined by your customer. Continuous improvement of the people and processes in your authority is the step you must take to improve your company’s Quality. Once we understand that Quality is the absence of waste, we can see that there are two related approaches that we can employ to eliminate waste and, thus, improve the Quality of our systems. It should be no surprise that the ASQ suggests manufacturers add agile methodology to their lean programs. The overlaps between quality management and agile are many.

Quality control techniques help to detect deviations from the specification. The user-based approach focuses exclusively on the customer in the determination of according to the manufacturing-based definition of quality quality. The strength of this approach is that it allows the customer the say in defining quality. However, this strength may also be viewed as a weakness.

Companies can build interest and enthusiasm by using databases to remember customer preferences. Unlock access to hundreds of expert online courses and degrees from top universities and educators to gain accredited qualifications and professional CV-building certificates. Quality has been the subject of many and varied definitions. Each definition has both strengths and weaknesses in relation to criteria such as measurement and generalizability, managerial usefulness and consumer relevance. With the tools of Quality 4.0 at their disposal, manufacturers have an opportunity to serve their customers better than ever before.

We will therefore in the following consider several more sophisticated definitions of product quality. The foundation of our Quality performance was dependent on our shared understanding of what exactly the customer wanted and how they would evaluate it. Documentation systems — defining all requirements and understandings in writing and covering almost every imaginable detail — was the systemic basis, the foundation for Quality in our companies.

In Juran’s definition, the quality of something depends on how someone will use it. Other definitions of quality tend to be similarly broad. In order to hold water as a concept, “quality” has to account for tremendous differences in manufactured products. Features of quality for, say, cutting-edge biologics, will differ from those for automobile parts. Quality standards for PCBs aren’t necessarily relevant for a food and beverage manufacturer.

  • Quality control techniques help to detect deviations from the specification.
  • Why do customers look for other options from other suppliers, even when we provide them Quality?
  • In contrast to quality as absolute, the value-based approach regards quality as relative to price.
  • This approach leads to a vertical or hierarchical ordering of quality.
  • In short, definitions of quality are vague because manufactured products are too varied to fit under a single, catchall definition.

As you may realize in the following, quality has many facets and is more complex than it seems. Second, the shift toward agile manufacturing has brought new attention to end-to-end product development. As all of these definitions of quality argue, quality starts with product design and continues through use by the consumer.

Definitions of Quality in Manufacturing

For example, while all the parts that the customer received met the spec, what if, in order to do so, we had to pay a crew a half shift of overtime to inspect? The additional cost, while not passed directly to the customer, still inflates our cost of doing business and, thus, makes our offerings more expensive. The customer, because they bid out jobs, understands implicitly that our offering is inferior — because they can compare the terms and prices that others offer. Our highest value resources include our performers and our processes.

Now, more than ever, manufacturers can leverage a dizzying range of tools throughout their QMS. 1.) Quality products satisfy their stated or implied needs. Even tried and true definitions (“Fitness for Use,” “Conformance to Requirements,” “When a thing does what it’s supposed to do”) can be maddeningly vague. They aren’t much help, however, where general definitions are concerned.

Second, quality products are free of deficiencies, meaning there’s no flaw in the design or production of the good that would prevent it from doing what it should do. Quality standards like the ISO family, IATF 16949, and GxP are essential for producing quality products. There are few better tools for controlling costs, streamlining compliance, and guaranteeing safe, performant products. Your customer tells you when they look for other suppliers, that there is waste in your offerings.

“Quality” is one of the most important concepts in manufacturing. But that doesn’t mean there’s agreement on what quality is. Ask 100 manufacturers and you’ll get 100 different definitions. Quality is the absence of waste in process and in our human performers. In the case of services, the measuring of quality may be more difficult.

In contrast to quality as absolute, the value-based approach regards quality as relative to price. According to this view, the buyer’s perception of value represents a mental trade-off between the quality or benefits perceived relative to price paid. The emphasis in the product-based approach is on quality as a precise and measurable variable. Any differences (in quality) that do occur reflect differences in the quantity of some ingredient or attribute possessed by a product. By this, the authors suggest that quality must be defined by customer needs in product design (what are the products and services they want?), as well as by how well the product satisfies those needs. First, quality products “satisfy their stated or implied needs,” meaning they do what they say they’ll do.

Continuously improving our people and processes leads to their performance at their highest and best use, and minimizes waste. This ensures Quality which our customers will recognize, and convince them to remain with us. Whilst the user-based approach to quality is rooted in the subjectivity of consumer preferences, the manufacturing-based approach, as the name suggests, focuses on internal matters. Products are designed and manufactured according to predetermined specifications.

‘Quality as the Absence of Waste’

This approach starts from the premise that quality ‘lies in the eyes of the beholder’. Consumers have specific wants or needs and those products that best meet their preferences are those that they view as having the highest quality. Quality 4.0, at its core, names a shift in all aspects of quality–from culture to benchmarking to production to compliance–in the digital era.
