Developing Product Design Requirements Using Kano Model


Product life cycles are getting shorter and customers are becoming more demanding such that businesses are looking for ways to meet these challenges with as little cost as possible. For businesses to be able to stay competitive, identifying customer needs accurately and transferring this information to the product designers in a short period of time becomes greatly essential.

To help businesses achieve their goals, this paper proposes teaching Kano model to the engineering and engineering technology graduates. This model is an effective six-sigma tool for classifying and prioritizing customer needs and helping the design and quality engineers to provide products with characteristics needed by the customers. The Kano model is a useful quality measurement tool in providing a level of sophistication not available in existing models of quality.

To prepare the graduates in using this model, it is taught in ‘Design for Manufacturing’ course offered in an undergraduate industrial engineering technology curriculum. The paper describes the Kano model and how it can be used in product design.


Manufacturing industry is looking for ways to reduce product development time and to introduce their products to the market more quickly. Additionally, product life cycles are getting shorter and customers are getting more selective by demanding sophisticated features in products. As a result, identifying customer requirements and transferring this knowledge along to the product development phase is essential for any business to stay competitive in the global manufacturing environment.

Over the past many decades, it has been observed that companies that have provided outstanding products and services have successfully survived the onslaught of competition. Only by designing quality in the products and services and focusing on quality improvements based on customer demands can a company expect to survive and grow in today’s market conditions.

For this reason of designing quality into the products, Dr. Walter A. Shewhart, in the 1930s, began developing his definition of quality, now known as Statistical Quality Control. During and after World War II, the tools for quality improvement continued to develop in the United States and Japan with the work of W.E. Deming, Joseph Juran, Kaoru Ishikawa, and Genichi Taguchi to name just a few of the quality gurus of earlier times.

In more recent times, Dr. Noriaki Kano, a very perceptive student of Kaoru Ishikawa, developed an interesting model to address the various ways in which quality practitioners can understand and prioritize customer requirements1. This model is well-known as Kano model of customer satisfaction. Even though it has been used in industry to a certain extent, its use has been limited because not many engineering educators are aware of its existence.
