Culture,leadership and motivation in two Commonwealth Caribbean countries: One look at the African Diaspora

Little is known of Caribbean people's views on their culture or of their beliefs regarding leadership and motivation. This study reports the results of a Delphi Technique with people in leadership positions and focus groups. Across groups, responses were relatively consistent: ethnicity and culture are described as influenced by religion, and Christianity in particular; African roots and country of origin are important; effective leaders are charismatic, visionary, results oriented, and they motivate others, lead by example, and develop vision and goals. Leaders believe motivation comes from making a difference for others. Nonleaders believe leaders are influenced by financial rewards and self‐fulfilment; nonleaders are motivated primarily by financial rewards. The results are generally similar to Western beliefs, but some interesting differences are identified. Copyright © 2014 ASAC. Published by John Wiley & Sons, Ltd.

Innovation in entrepreneurial organisations: A platform for contemporary management change and a value creator

PurposeThis article examines the significance of innovation to organisations following strategies of entrepreneurial orientation. In particular, the study looks at the significance innovation adds to the implementation of contemporary management control systems (MCSs) and to improved performance in these organisations.Design/methodology/approachA quantitative analysis was conducted based on a random sample of Australian manufacturing companies. A structural equation modelling approach was adopted to test the study hypotheses.FindingsResults suggest that innovation mediates the relationships between entrepreneurial strategy and each of participative budgeting, the balanced score card (BSC), total quality management (TQM), just in time (JIT), and organisational performance. The study does not indicate a significant relationship between entrepreneurial strategy and activity based costing (ABC), even when innovation is in place.Originality/valueThe study empirically tests the vital role of innovation in the organisational adaptive cycle to entrepreneurial strategies, described earlier by Miles and Snow (1978). Further, the study validates a multi-dimensional strategy model first suggested by Langfield-Smith (1997).
