Kano Model Applications in Customer Satisfaction Engineering

The Kano model, formulated in the 1980s, has become integral to customer satisfaction engineering by classifying product and service attributes according to their emotional impact on users. It distinguishes between must-be attributes (basic requirements whose absence causes dissatisfaction but whose fulfilment does not increase delight), one-dimensional attributes (performance features with a proportional effect on satisfaction) and attractive attributes (features that surprise and delight when present without evoking dissatisfaction when absent). Engineers and managers worldwide have combined the Kano framework with techniques such as quality function deployment, fuzzy logic and importance–performance analysis to prioritise resource allocation, refine feature sets and optimise processes across sectors. Applications range from self-service technologies and automated logistics to healthcare and retail environments. By translating customer perceptions into actionable engineering specifications, the model fosters human-centred innovation and informs strategic decisions—such as software interface design for parcel delivery networks and protocol enhancements in clinical settings—demonstrating its enduring relevance for aligning technical development with customer expectations.

Recent research on automated parcel locker services in urban areas applied the Kano model to analyse user priorities for features such as mobile-app functionality, precise parcel-to-box allocation and accessibility provisions for disabled customers. Coding responses into Kano categories revealed that a reliable app interface and correct parcel placement are clustered as one-dimensional and must-be attributes, guiding optimisation of both hardware and software in last-mile delivery engineering. A study in the retail sector surveyed over 400 customers on in-store characteristics, identifying visually appealing facilities and error-free transactions as must-be features whose absence triggers strong dissatisfaction. In contrast, an intuitive store layout and prompt staff assistance emerged as attractive attributes that enhance satisfaction without being strictly required, enabling facility managers to balance operational robustness with experiential design. In the healthcare domain, a pilot evaluation of public-private partnership hospitals used the Kano model to assess clinical, administrative and environmental service factors. Most elements—ranging from waiting-area comfort to staff communication—were categorised as one-dimensional attributes, where incremental improvements led directly to higher patient satisfaction. These insights supported targeted interventions such as streamlined admission procedures and enhanced information channels, illustrating the model’s global applicability to engineering service quality improvements.

Technical terms

Kano model: A two-dimensional framework for classifying product or service attributes based on their ability to satisfy or dissatisfy customers.

Must-be attribute: A fundamental requirement whose violation causes dissatisfaction, while its fulfilment does not proportionally increase satisfaction.

One-dimensional attribute: A feature with a linear relationship between performance level and customer satisfaction; enhancements yield proportional satisfaction gains.

Attractive attribute: A feature that delights customers when present but does not cause dissatisfaction when absent.

Fuzzy Kano model: An extension of the Kano model incorporating fuzzy logic to handle uncertainty and vagueness in customer evaluations.
