Abstract
In this chapter the literature related to the topics discussed will be presented in a concise rather than comprehensive form. The reason is to allow the readers to progress to the main topic of discussion without delays. Also, one has to bear in mind that the topic of innovation is multi-disciplinary, and the topic of this book is extremely so. The topics presented in the literature review will present the scope of topics related to the move from start-up to a complete firm. As they encompass the main aspects related to the operation of the firm, they cover a wide area of research and threaten to distract the reader from the topic at hand. Therefore, for each of the topics presented, a skeleton of literature review will be presented mainly to offer a starting point to those interested to pursue a specific topic rather than to present a comprehensive picture of the literature.
