Book excerpt: Faced with chaotic environments, it is not possible to make totally efficient forecasts, especially when it is necessary to analyze events with multiple variables and micro, small, and medium enterprises (MSMEs) constantly face events that escape the laws of the market. The handling that has been given to the crisis caused by the coronavirus has been trial and error, and the economic, social, and environmental results remain to be seen. The markets and the world are chaotic. With the markets in chaos due to the COVID-19 pandemic, it is important to look at the methods used in these environments to promote business success. The Handbook of Research on Management Techniques and Sustainability Strategies for Handling Disruptive Situations in Corporate Settings elaborates on the skills, techniques, and tools that are more useful for these environments and identifies what makes companies that work well in organizational chaos and in chaotic economic environments perform better than companies that are well organized. Covering topics such as strategic management, multidimensional chaos approach, and the global unstable market, this book is essential for managers, executives, academicians, policymakers, entrepreneurs, researchers, undergraduate and graduate business students, and any person interested in state-of-the-art business issues.
