Introduction• Product/service quality is main
antecedent of customer satisfaction (Cronin & Taylor 1992; Anderson & Sullivan 1993; Brady et al. 2002)
• Important to find out how each attribute performance impacts on satisfaction
• Prof. Kano pointed out that not all product/service attributes have same role in satisfying customer needs
![Page 4: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/4.jpg)
Origins of the Kano Model
• Developed foundation for an approach on “Attractive Quality Creation” commonly referred to as the “Kano Model”
• Challenged traditional Customer Satisfaction Models that More is better, i.e. the more you perform on each service attribute the more satisfied the customers will be
![Page 5: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/5.jpg)
Origins of the Kano Model
Proposed new Customer Satisfaction model (Kano Model)Performance on product and service
attributes is not equal in the eyes of the customers
Performance on certain categories attributes produces higher levels of satisfaction than others
![Page 6: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/6.jpg)
Introduction• Separate among satisfaction, dissatisfaction
and delight since factors that dissatisfy and that delight are often different (Rust, Zahorik & Keiningham 1994)
• Ex. If a customer approaches an ATM then finds it to be out of cash, the customer will likely be dissatisfied, but it is unlikely that finding an ATM stocked with cash would
satisfy or delight the customer
![Page 7: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/7.jpg)
Kano’s Model of Satisfaction
Technique use to determine which influence the attributes of products and/or services have on customer satisfaction (Kano et al. 1984)
![Page 8: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/8.jpg)
Kano’s Model of Satisfaction
• Which products and services can be used to obtain a high level of customer satisfaction?
• Which product features have a more than proportional influence on satisfaction
• Which attributes are an absolute must in the eyes of the customer?
![Page 9: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/9.jpg)
Kano’s Model of Satisfaction
Product/service attributes can be classified into three groups1. Basic attributes/dissatisfiers/Must-have2. Performance/one-dimensional
attributes3. Exciting attributes/satisfiers/Attractive
![Page 10: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/10.jpg)
Basic Attributes/Dissatisfiers
• Minimum required features that customer naturally expect from a product/service
• Not able to elicit satisfaction but can produce dissatisfaction when not fulfilled
• ex. Punctually and safety of airline
![Page 11: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/11.jpg)
Performance/One-dimensional Attributes
• Produce both satisfaction dissatisfaction depending on performance levels
• satisfaction is proportional to the level of fulfillment of these attributes
• ex. Gasoline consumption of a car; lower consumption leads to higher customer satisfaction
![Page 12: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/12.jpg)
Exciting Attributes/Satisfiers
• Produce satisfaction when delivered but cause no dissatisfaction if not delivered
• High performance on these has a greater impact on overall satisfaction rather than low performance
• ex. (unexpected) promotional offers
![Page 13: Kano’s Model of Customer Satisfaction How to Delight Your Customers A. Nitipan Ratanasawadwat Assumption University of Thailand](https://reader036.vdocument.in/reader036/viewer/2022062313/56649d0c5503460f949e133d/html5/thumbnails/13.jpg)
Three-Factor Theory

Kano’s Model Process
• Identify the Voice of the Customer• Translate Voice of the Customer into
Critical to Quality Characteristics (CTQs)• Rank the CTQs into three categories:
– Dissatisfier - Must be’s – Cost of Entry– Satisfier – More is better – Competitive – Delighter – Latent Need – Differentiator
• Evaluate Current Performance

• Must Be’s - Focus Groups, Lawsuits and Regulations, Buzz on Internet
• Satisfiers - Competitive Analysis, Interviews, Surveys, Search Logs, Usablity Testing, Customer Forums
• Delighters - Field Research, Marketing/Branding Vision, Industrial Design, Packaging, Call Center Data, Site Logs

2. Analyze & Brainstorm• Analyze data from available sources• Brainstorm list of features and functionality• Determine type of requirements:
– Output Requirements – Service Requirements
• Kano Model Requirements Survey – User Survey
• “Functional form” vs. “Dysfunctional Form”– “How would you feel if the product had feature X?”– “How would you feel if the product didn’t have feature X?”
– Kano Questionnaire Answers:• I like it.• I expect it.• I’m neutral.• I can tolerate it.• I dislike it.

Importance of Customer Satisfaction and Loyalty
• “Satisfaction is an attitude; loyalty is a behavior”
• Loyal customers spend more, are willing to pay higher prices, refer new clients, and are less costly to do business with.
• It costs five times more to find a new customer than to keep an existing one happy
