In 2007-8 the Australian Catholic University (ACU National), undertook a project to develop new resources to provide training and support in eLearning for staff and students. The project was undertaken by a multidisciplinary team drawn from all six campuses and was led by an externally contracted Project Manager/eLearning specialist. This reflective case study reports on how the use of ACU's project management methodology and the selection of a matrix organisation for the project, resulted in the nurturing of existing communities of practice (CoPs) around both eLearning and project management at ACU. Key recommendations are that effective project management practice and a matrix project organisation can promote and nurture knowledge sharing amongst CoPs in a university setting.
