Notability unclear at best. Hello71 (talk) 18:12, 16 June 2012 (UTC)
Comment - definitely agree with the nominator that the notability of this topic under this title is murky. But this topic, under one name or another, has certainly been a hot subject of research over recent years in the construction industry (the area I know best). Personally I can't see any authoritative sources on this topic online. Maybe someone will add references in the next 7 days, if not I will change my 'vote' to delete.

Comment. I see plenty of Google books and Google scholar hits, which suggests the topic is notable enough. I have to say that at first glance the article reads well, yet on deeper inspection turns out to be uninformative. I can't even figure out whether its topic is the collaborative management of projects, or the management of collaborative projects. --Lambiam 21:24, 16 June 2012 (UTC)
Comment. For the reason of notability I now added some more links which partially are available only in German. This is the reason why in the first version I left them. To answer the "Title"-Comment: The collaboration happens in the management of the project i.e. the methodology of the project management is ment to be collaborative. (Pls. apologize my bad English). --Actano Ute (talk) 13:25, 18 June 2012 (UTC)
Relisted to generate a more thorough discussion so a clearer consensus may be reached.
