Iterative Entwicklung
1 2 3
Iterative Entwicklung baut zunächst eine rohe Vision und verfeinert schrittweise.
Iteration erlaubt es von einer vagen Idee auszugehen.
Größere Anpassungen zwischen Iterationen möglich.

Inkrementelle Entwicklung
1 2 3 4 5
Inkrementelle Entwicklung baut ein Teil nach dem anderen.
Es muss eine konkrete Vision geben um Inkremente definieren zu können.
Anpassungen an bereits entwickelten Inkrementen nicht möglich.

Basierend auf einer groben Vision werden schrittweise Verfeinerungen vorgenommen.
Es werden zunächst die wichtigsten Inkremente entwickelt.
Es verbleibt die Möglichkeit Anpassungen zwischen Iterationen vorzunehmen.

Fazit
Integration von Usability Engineering in agile Prozesse
Usability Engineering
Von isolierter Praxis zu
integrierter Kooperation
Gestaltung von Inkrementen /
Features statt ganzheitlichen
Produkten
Weniger Dokumentation durch
leichtgewichtige Entwürfe statt
ausführlicher UI Spezifikation
Design und Evaluation
gemeinsam mit Entwicklern
17
Agile Softwareentwicklung
Integration einer vorgelagerten
Visionsphase mit
Nutzungskontextanalyse
Einbindung echter Nutzer in den
Entwicklungsprozess (Product
Owner + Usability Engineer)
Aktive Beteiligung an Usability-
Aktivitäten
Integration von Design Sprints für
Feature-übergreifende Gestaltung
und Redesigns
