Modelling Complex Projects - Williams, Terry

. .

Résumé :
Es ist allgemein bekannt, dass die traditionellen Methoden des Projektmanagment f?r die Bew?ltigung der modernen Projektsituation nicht mehr ausreichen. Heute werden Projekte immer komplexer, und die Kunden geben einen immer enger gesteckten Zeitrahmen vor. Entsprechend gilt es, Probleme, wie z.B. unzureichende Planung und Risikoanalyse, unwirksame Projekt?berwachung und -steuerung sowie wenig fundierte nachtr?gliche Analysen von vornherein zu vermeiden. Dieses Buch hilft Ihnen dabei! Modelling Complex Projects ist das erste Buch, das sich ausschlie?lich mit dem Thema Projektmodellierung besch?ftigt. Es vermittelt wirkungsvolle Modellierungstechniken, die der besonderen Komplexit?t moderner Projekte gerecht werden. Diskutiert wird eine breite Palette neuer Techniken, wobei auch auf ihre jeweiligen Vorteile und Kombinationsm?glichkeiten eingegangen wird. Mit zahlreichen Fallstudien....
