With growing unemployment, especially among engineers and scientists, the need for entrepreneurship development is obvious and this book has been written to provide suitable guidelines for this purpose. The book will also serve as a textbook for graduating engineers and scientists for the course on Entrepreneurship Development, which has already been introduced in several institutions. The material, presented especially on financial aspects, will be useful in developing suitable projects, whether in small scale or large scale. Also, the book will be useful to short term training programmes, generally organized by state entrepreneurship development institutes jointly with State Directorate of Industries, Financial Institutions, Department of Science and Technology, Govt. of India, etc.
