Executives are frequently appointed to managerial posts because of their skill in, for example engineering, finance or marketing. But, they may be unable to motivate others and this managerial efficiency can result in low profitability or even failure. All managers need to work with and through subordinates to optimes organisational performance. This book therefore introduces selected aspects of those behavioural skills that are required of individuals if they are to be effective as managers. Each concept in the book is presented in the form of a lively case history of actual situations in fisheries or aquaculture. These are analysed in detail but simplified to highlight specific issues. Practising managers, public sector advisors and students will all find the book full of helpful guidelines and the principles outlined could resolve many real-life problems.
