The user has been very well defined over the last decades. With human-centered design becoming more widely applied within various industries, the user's needs are being taken into account more than ever. What is often overlooked is the user's counterpart: the non-user. Integrating the non-user into modern development projects provides great additional value. This paper is compiling current definitions in order to analyse them within the context of product development and to make a contribution toward a comprehensive definition of the non-user that can be applied to various disciplines.
Klein- und mittelständische Unternehmen (KMU) sehen immer mehr den Herausforderungen und Chancen einer nachhaltigen Produktentwicklung entgegen, da die Entwicklung und Herstellung von Produkten zwangsläufig mit Umweltaspekten verbunden sind. Eine gute Anwendung von Methoden und Werkzeugen bestimmt so mitunter über Erfolg und Misserfolg eines Produktes als auch dessen Nachhaltigkeit und ist damit zentrales Element bei der Entwicklungsarbeit. Somit bestimmt eine dauerhafte Integration von Werkzeugen eine langfristige Wettbewerbsfähigkeit von Unternehmen. Da die geringeren Kapazitäten und Rahmenbedingungen von KMUs jedoch eine Barriere bei der Integration von Methoden und Werkzeugen darstellt, wird ein Ansatz beleuchtet, der mit Zuhilfenahme von Filtern bei der passenden Auswahl von Methoden und Werkzeugen Unterstützung bietet. Es werden Hemmschwellen und Erfolgsfaktoren bei der Anwendung von Methoden und Werkzeugen beleuchtet und ein möglicher Prozess skizziert, um die Integration zu fördern, die Mitarbeiter des Unternehmens zu schulen und langfristig die Anwendung von Methoden und Werkzeugen zur nachhaltigen Produktentwicklung in KMUs zu implementieren.
The House of Quality is an established model for human centric product development, that among other aspects uses both customer attributes and product requirements to define a product and its most important features. Industry application of this model is difficult due to its overall complexity and lack of clear instructions on how to specifically build a catalogue of customer attributes from user research in particular and how to prioritize them.
This contribution seeks to simplify customer attribute formation and management by introducing the concept of non-use within a use case. Types of non-use and reasons for non-use of robot vacuums are examined and decoded into attributes. Attributes of users and non-users are compared and analyzed. By introducing a clear interview structure for users and non-users, this contribution visualizes how to translate interviews to attributes used within the House of Quality.
The use case discussed in this contribution indicates that non-use can yield more information than conventional user research, since non-users’ reasons for non-use were more extensive than users’ negative feedback about the product and could therefore generate more attributes. Industry feedback suggests that non-user attributes are similar to user attributes and can therefore be used in place of user attributes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
