In this article we explore qualities that have emerged out of the application of modern attachment theory and its contribution to successful global family businesses. The analysis focuses on the nature of attachment behaviour, how and why loss occurs, the mourning process as a function of attachment, and the importance of honouring the loss of these attachments. We suggest completion of the mourning process may lead to the renewal or reorientation of the business in a more constructive and productive direction—ultimately enhancing the organisation's strategic capacity. The research data included is based on in-depth cross-cultural analysis with case study data representing China, Tanzania, USA, and Sweden.
