Agile Modeling

Effective Practices for Extreme Programming and the Unified Process

• Broschiertes Buch

Produktbeschreibung

XP (Extreme Programming) hat in der Software Development Community jetzt für ähnlichen Aufruhr gesorgt, wie Design Patterns vor ein paar Jahren. Zwar ist XP eine Methodik zur schnelleren Softwareentwicklung, aber sie gibt dem Entwickler nicht genügend Modellierungszeit, die jedoch wichtig ist, um sicherzustellen, dass ein Projekt die gewünschten Anforderungen auch erfüllt. Darüber hinaus funktionieren Standard-Modellierungstechniken auf der Basis von UML (Unified Modeling Language) häufig nicht mit XP. In diesem innovativen Buch präsentiert Software Development Kolumnist Scott Ambler Agile Modeling (AM) - ein Verfahren, das er speziell für die Modellierung von XP-Projekten entworfen hat und das Teile von UML und RUP (Rational's Unified Process) einsetzt. Ambler erklärt anhand zahlreicher Fallstudien anschaulich, was AM ist und wie Software-Experten AM, UML und RUP in ihre Entwicklungsprojekte einbinden können. Die begleitende Website (www.agilemodeling.com) bietet Updates, Links zu XP- und AM-Resources sowie laufende Fallstudien zum Agile Modeling.
