As a result of far-reaching economic and social trends, the Australian Defence Force relies on commercial contractors, not only for the supply of platforms and systems but also for the repair, maintenance and adaptation of those platforms and systems in-service. Effective management of the business relationship between defence customer and commercial supplier across the full materiel life cycle is therefore a key input to defence capability. The Commercial Skills in the Public Sector course is intended to help defence managers develop the commercial acumen required to manage defence business relationships with an eye to their wider defence capability significance. To this end the course will address the interface between Defence-specific requirements and the wider principles of financial management, legal practice, contracting, procurement and the management of supplier relationships.
