Book excerpt: This book discusses the existing management approaches for dealing with changes, namely readiness, maturity, and resilience. Although these concepts have been discussed for several years now, their importance grows when companies must deal with extended changes in economies. The changes are of a different nature: social, technological, and political, and they strongly impact every aspect of economies and companies’ activity. Is it possible to be ready for the changes? Should companies be resilient to disruption? These are the questions the managers are trying to answer, yet they need some support from academics. This book explores the synergy between the state-of-the-art knowledge and experience of companies to create a Contemporary Management Model. The scope of this book covers the methodology with an introduction and discussion of the key ideas and concludes with a presentation of the Contemporary Management Model followed by the practical validation and verification of the model based on case studies. This book is simply about developing the readiness and resilience of resources and processes, especially from a tactical perspective.
