Leadership is inherent in every being despite one's job profile. But qualitative training and other traits are very important for the right behaviours. Every follower possesses attribute of a leader but because these are somewhat concealed, to lead effectively becomes a huge challenge to many. This book is as a result of many years of research. It focused on discovering those behavioural attributes that could combine effectively with the leader's competing roles to enhance his performance. A Competing Value Framework (CVF) was applied to understand the leadership behaviours, characteristics, attributes, and roles that could influence a leader even in the face of contingency factors. The result was quite revealing. Leaders that combine their roles with other attributes/skills achieve behavioural complexity, which are performance enhancing behaviours. Furthermore, leaders are distinguished by their unique mental attitude, particularly in four roles they play: motivation, vision, analytic, and task master roles. Combination of these with other attributes and characteristics enhances the leadership complexity. This book is a useful material for those in the ministries, academia, and organisations of different sizes. It's a book every leader must possess to comprehend the behavioural complexities relevant for organisational performance.
