CRC-VorgehensmodellClass, Responsibilities and Collaboration

Eine Karteikarte pro Klasse Karteikarten werden an alle

Gruppenmitglieder verteilt Klassenname, Verantwortlichkeiten und

Beziehungen werden notiert Teammitglieder simulieren die

Kommunikation der Objekte


Alle Teammitglieder sind am Entwurfsprozess gleichermaßen beteiligt

Unterschiedliche Ansätze führen zu konstruktiven Diskussionen

Ergebnisse sind bereits echte Entwurfslösungen



Ergebnisse fließen ein in die... Umsetzung des Klassendiagramms, Erstellung von Sequenzdiagrammen und Verfeinerung des Oberflächenprototyps.
