Book excerpt: This reader-friendly series is must read for all levels of managers All managers, whether brand-new to their positions or well established in the corporate hierarchy, can use a little brushing-up now and then. The skills-based Briefcase Books Series is filled with ideas and strategies to help managers become more capable, efficient, effective, and valuable to their corporations. The ability to give a great presentation can be a tremendous career booster, while the opposite can keep a manager on a dead-end path. Presentation Skills for Managers is a practical, advice-filled book on how to create and make compelling and persuasive presentations. Besides reviewing material on preparing and delivering effective presentations, it includes new special coverage of the development and use of Powerpoint slides, something not found in most books on presentations.
