Project Scheduling—Theory and Practice

The project scheduling problem involves the scheduling of project activities subject to precedence and/or resource constraints. Of obvious practical importance, it has been the subject of intensive research since the late fifties. A wide variety of commercialized project management software packages have been put to practical use. Despite all these efforts, numerous reports reveal that many projects escalate in time and budget and that many project scheduling procedures have not yet found their way to practical use. The objective of this paper is to confront project scheduling theory with project scheduling practice. We provide a generic hierarchical project planning and control framework that serves to position the various project planning procedures and discuss important research opportunities, the exploration of which may help to close the theory‐practice gap.

Motivating job design as a factor in open source governance

Successful open source software (OSS) projects can be considered as examples of how ambitious work results can be achieved in web-based collaboration even when monetary incentives are low or absent. While former explorations of motivational processes in OSS projects primarily focused on person-oriented aspects such as motives, interests, and expected benefits of contributors, job-related factors have been largely neglected. After discussing the limitations of a person-oriented focus, a research perspective is suggested that concentrates on job design and work context in OSS based on frameworks from work psychology. A theoretical analysis is presented discussing job characteristics of successful OSS projects as potential explanations of the high motivation of OSS contributors. Compared to a person-oriented perspective, the results of a job-oriented approach might be better transferable to other projects (both OSS and “closed source” software development) and provide guidelines for the governance of successful web-based collaboration.
