Managing National Defence Using a'Linked- Portfolios' Approach

摘要

The current, rapidly changing technical, financial, national security and societal environment presents many challenges to those entrusted to develop and maintain national defence capability. It has become increasing obvious over recent years that the classical methods of undertaking these tasks have been found wanting around the world. This paper examines the drivers for defence capability management and proposes an improved concept, derived from systems theory, based on aggregating capabilities into portfolios for the duration of their lifecycle: from concept through to disposal. The rules for determining portfolio membership are discussed and the advantage of linking portfolios into an overall structure of portfolios is pursued. The paper concludes by exploring methods of evaluating portfolios.
