Abb. 4 Personas illustrieren wichtige Eigenschaften und Bedürfnisse der Benutzer im Hinblick auf ein geplantes neues Produkt Was Sie über Ihre Benutzer festhalten sollten Im Rahmen eines Projekts entstehen mehrere Personas, die jeweils einen typisierten Benutzer beschreiben. Eine Persona kann über folgende Eigenschaften Auskunft geben: • • • • • • • Ziele der Benutzer, Beruf, Funktion, Verantwortlichkeiten und Aufgaben, Fachliche Ausbildung, Wissen und Fähigkeiten, Verhaltensmuster und Vorgehensweisen, Werte, Ängste, Sehnsüchte, Vorlieben, Allgemeine Computerkenntnisse, Kenntnisse über verwandte Produkte, Vorgängersysteme, Konkurrenzprodukte, • Verbesserungspotenzial in der heutigen Situation, • Erwartungen an eine neue Lösung.

2). Personas stellen prototypische Benutzerprofile dar, während Szenarien die Arbeit mit dem neuen System aus Benutzersicht beschreiben. Personas und Szenarien bringen die im Contextual Inquiry erarbeiteten Ergebnisse auf den Punkt und dienen als Grundlage für die Entwicklung. Personas und Szenarien liefern auch eine gute Basis für den Entwurf eines Use-Case-Modells oder User Stories (siehe Abschn. 5). Dabei wird zuerst eine Übersicht über den funktionalen Umfang der neuen Lösung erarbeitet und in einem zweiten Schritt das Verhalten des Systems gemäß den Qualitätsanforderungen und Rahmenbedingungen detailliert.

3) hat ein Projektteam die Möglichkeit, Lösungsideen anschaulich darzustellen, um beispielsweise Feedback von Benutzern und Führungskräften zu erhalten und neue Teammitglieder einzuführen. Storyboards visualisieren und detaillieren die Anwendung aus Benutzersicht, indem sie einen ersten Eindruck über die Abläufe der Benutzerschnittstelle im vorgesehenen Kontext geben.
