Title: Consulting Services and Their Importance for Entrepreneurs. Author: Dr. Badr Al-Harbi. Introduction: Prof. Dr. Ahmed bin Abdulrahman Al-Shamimri. Between the period the author spent working in the consulting services sector - and still does - and what he concluded from his doctoral dissertation he prepared entitled: (Consulting Services and Their Importance for the Business Sector), and based on what he sees as the lack of discussion and writing about consulting services for entrepreneurs, he extracted this book as a guide for entrepreneurs, through which he contributes to achieving their leadership and charts a safe path for their relationship with consulting services. The book discusses the need of entrepreneurs and their emerging companies for consulting services, indicating that they are the ones who most need someone to guide them and provide them with professional solutions to implement their creative ideas. Therefore, through the chapters of this book, the author defines consulting services, discusses their importance, the need for them, the most appropriate choice among consultants, experts, and consulting firms, the tasks required of the consultant and the limits of their responsibilities, the criteria for evaluating the work of consulting firms, and the formulas and mechanisms for contracting with them. He also discusses some stories and practical cases of successes and failures achieved by start-up companies or entrepreneurs, as well as real consulting situations through the author's work in the consulting services sector, or situations he has taken from their sources to benefit from them and learn from their events. The author notes throughout his book that it is not strange to emphasize the importance of consulting services for entrepreneurs or the business sector, but what is important is to know how we can achieve maximum results and best practices and methods, and even how to deal with the outputs, solutions, and recommendations of consulting firms.
