What are the benefits and challenges of using the Kano model for user story prioritization?

Kano model classifies features into three categories: Basic Needs (Must-Haves), which are essential for the product to function and cause frustration if missing; Desired Features, which are important but not dealbreakers; and Delightful Features, which exceed expectations and create excitement. By understanding how features impact satisfaction, the Kano model helps teams prioritize user stories. They can focus on building Must-Haves first, then Desired Features, and finally use Delightful Features to set their product apart.

This model describes the connection between customer satisfaction and the realization of customer requirements. There are 5 important parts of this. Threshold attributes (Must-be qualities), Performance attributes (One-dimensional qualities), Excitement attributes (Attractive qualities), Indifferent qualities, and Reverse qualities.

Design a Kano questionnaire with two questions per user story: Positively: How happy would users be if the product HAD this feature? Negatively: How happy would users be if the product DIDN'T HAVE this feature? Use a scale like "Very Happy," "Somewhat Happy," "Neutral," "Somewhat Unhappy," or "Very Unhappy." Capture the responses for each user story with the targeted user segments. Based on the response, categorize stories into these groups: Must-Haves (Basic Needs): Top priority! Users expect them and get frustrated without them Performance Features (Desired): Important! These become more valuable with better performance Indifferent Features: Low priority. They don't significantly impact user happiness Reverse Features: Avoid these!

A través de la categorización de historias de usuario, el modelo Kano facilita el establecimiento de un vocabulario compartido para discutir características tanto dentro del equipo como entre los interesados. Esta claridad mejorada ayuda a entender comprender la influencia de cada historia en la satisfacción del usuario y los objetivos del negocio. Al identificar atributos de "Emoción", el modelo Kano proporciona dirección para desarrollar características que diferencien su producto de otros. Además, el modelo Kano optimiza la asignación de personas y recursos al priorizar características "Imprescindibles" inicialmente, y posteriormente guiar las inversiones estratégicas en características de "Emoción".

Ao entender quais características s?o básicas, de desempenho ou excitantes para nossos usuários, podemos direcionar nossos esfor?os para aquelas que agregar?o mais valor e satisfa??o. Além disso, o modelo Kano nos ajuda a antecipar as expectativas dos usuários e a desenvolver um produto que os encante. Isso nos coloca em uma posi??o vantajosa no mercado, pois estamos oferecendo n?o apenas o que os usuários desejam, mas também superando suas expectativas e proporcionando experiências memoráveis. Em resumo, o modelo Kano é uma ferramenta valiosa para product owners na cria??o de histórias de usuário, pois nos ajuda a entender as necessidades e desejos dos usuários e a desenvolver um produto que os encante e os mantenha satisfeitos.

Firstly, it steers development efforts towards features with the biggest customer satisfaction impact. By identifying Must-Haves, you ensure the product fulfills basic needs and avoids frustration. Secondly, it helps you focus on features that will progressively improve satisfaction. This ensures you're not just meeting baseline expectations but also delivering value through better performance. Finally, the Kano model allows you to identify features that can truly excite users, potentially giving your product a competitive edge. Overall, the Kano model ensures you're prioritizing user stories that will deliver a product that satisfies core needs, keeps users happy, and has the potential to surprise and delight them.

This feature helps you to focus on one more important story. It helps us to save costs and time, and it helps the end customer to be more satisfied with some unspecified performance point delivery. It also helps the team to be clear about user stories and their priority.

Si no hay una investigación profunda del usuario, del cliente, la aplicación del modelo Kano puede convertirse en un dolor de cabeza. El uso del modelo Kano exige que el equipo conozca íntimamente al usuario, que lo vea en acción: ?qué hace? ?Con quién lo hace? ?Qué información intercambia? ?Cómo? ?Qué experiencias hacen que el usuario sea éxito? ?Cuáles hacen que falle? Estas y otras preguntas se deben responder por observación, ojalá de todo el equipo, para que haya diversidad de perspectivas, sobre todo en entornos complejos. Con ese conocimiento, la aplicación del modelo fluye sin contratiempos y es más efectiva.

One hurdle is the subjectivity of user responses. Interpreting "satisfaction" can be tricky, and what excites one user might be expected by another. This can lead to misclassifications and potentially skew prioritization. Additionally, the Kano model focuses heavily on user feedback at a single point in time. Customer needs and expectations can evolve quickly, so features categorized as Must-Haves today might become basic expectations tomorrow. This necessitates revisiting the Kano model periodically to ensure prioritization stays aligned with current user needs. Finally, gathering accurate user input can be time-consuming and require careful questionnaire design to avoid biased responses.

O método INVEST é eficaz para garantir clareza e gerenciabilidade nas histórias de usuário, mas pode n?o oferecer uma vis?o completa das necessidades dos usuários. Por outro lado, o modelo Kano classifica as características do produto em básicas, de desempenho e excitantes, permitindo prioriza??o eficaz e antecipa??o das expectativas dos usuários, levando a produtos inovadores e diferenciados que geram maior satisfa??o do cliente.

Clearly define the user group and specific features you're evaluating to get focused results. Design a Kano questionnaire with two well-defined questions per story: positive (benefit of having the feature) and negative (impact of missing the feature). Use an easy-to-understand scale like "Very Happy" to "Very Unhappy" for user responses to ensure consistent data. Focus on Must-Haves first (avoid frustration), then Performance Features (improve satisfaction), and finally consider Excitement Features (stand out). Defer or eliminate Indifferent and Reverse Features. Don't work in isolation. Use Kano alongside user interviews, data analysis, or business goals for a holistic prioritization approach.

Evaluate your products often to keep up with industry changes - a feature that may have been a peak of delight on your Kano model might now be a "must have." Airpods are a great example. When they came out, ubiquitous connectivity and always charging cases created a seamless user experience that at the time was a peak of delight. Fast forward to today. Think of how many airpod knock offs there are. Today would you purchase bluetooth earbuds that didn't easily connect to your device, or that felt like they were a hassle to charge?
