Despite increasing interest among practitioners and the recent scientific explorations on the dynamics of boundary management in project and team contexts, the existing studies seems to lack empirical understanding on the factors that explain the boundary management behavior of project managers....

Traditionally allocation of personnel for projects has been seen as a manage-ment task. Recently, however, more and more organisations are treading new paths when staffing projects. In this article we examine a new staffing proce-dure, in which enrolment is dependent on employees voluntarily...

(Einleitung)(...) Ziel der vorliegenden Arbeit ist deshalb die Übertragung dieses Instruments auf die Entstehungsphase einer Immobilie, um die Kosten frühzeitig unter Berücksichtigung der Nutzeranforderungen zu gestalten und zu steuern. Um dabei einen engen Bezug zur praktischen Umsetzung...

This paper analyzes situations in which a project consisting of several activities is not realized according to plan. Ifthe project is expedited, a reward arises. Analogously, a penalty arises if the project is delayed. This paper considersthe case of arbitrary nondecreasing reward and penalty...

This paper investigates the role of skills and the division of labor among participants in collective inventions. Our analysis draws on a large sample of projects registered at Sourceforge.net, the world's largest incubator of open source software activity. We test the hypothesis that the level...

A systems analysis perspective is adopted to examine the critical properties of the Free/Libre/Open Source Software (FLOSS) mode of innovation, as reflected on the SourceForge platform (SF.net). This approach re-scales March's (1991) framework and applies it to characterize the innovation system...

We consider a project scheduling problem where the precedence constraints graph is an out-tree. The processing times can be compressed by using additional resources, which causes cost and simultaneously reduces the processing times of jobs. The objective is to minimize the sum of total lateness...

Over the years numerous branch-and-bound procedures for solving the resource-constrained project scheduling problem have been developed. Enumerating delaying alternatives, extension alternatives, feasible posets, feasible sequences or feasible subsets, they all aim at finding as fast as possible...
