You can zoom in on the operational details or take the long view of the strategic content depending on your interests or current needs. You can then explore your own management and leadership challenges through the A to Z sections of the App, which link explicitly with the opening story.The A to Z sections contain a range of models which have been selected for their value in meeting the challenges of modern management and leadership. These models are described in brief to promote uncluttered learning, relate to the opening story to promote deeper understanding, and are the foundation for 26 exercises to promote individual, team and organization development. Three Questionnaires provide the opportunity for you to reflect in detail on your preferred learning style, leadership style and emotional intelligence. Finally, links to The Knowledge Biz facebook page and The Knowledge Biz blog provide additional resources and the opportunity for you to further explore the material contained in this resource with other users of the App.
