When an engineer thinks about the IT industry, a tendency to consider only the technical side of it is likely to appear. That is quite natural as successes in this area are obviously related to the innovation and exciting inventions that are presented throughout the pages of our magazine. However, as in the case of each industry, there are also other very important aspects, i.e., economic, legal, etc. Therefore, to be effective in practical IT, a network specialist needs not only to be expert in one’s own field; they also need to be aware of the general business context, since in many cases this is the source of inspiration or, on the other hand, problems influencing the every-day operation. This book authored by two distinguished practitioners will help with getting the required knowledge. The content is divided into 10 chapters, each of which is some 30-40 pages long. Hence, it is possible to get acquainted with a single piece of the presented material during an afternoon. While almost all of the presented notions are described in the context of IT issues, some of the chapters cover very general economic problems related to business operation: business strategy concepts; corporate finance and governance; customers and marketing; and people and organizational development. These general topics are intertwined with the chapters detailing specific aspects of the field interesting for us: regulation in telecommunications along with the recent emphasis on opening markets, economics of network design, and the management of networks and services. Although throughout the book the British perspective of the authors is seen, there are many examples covering European, American and (rarely) Asian markets. Anyway, globalization, so important for today’s big IT businesses, is tangible for the reader. The book can be recommended to students as a handbook, being a perfect supplement for the lectures on entrepreneurship or practical project management courses that are typically a part of the curriculum for a future IT engineers. This is also a good summary of various aspects of networking from the organizational and global viewpoint, a perspective that might sometimes be lost when a student encounters various topics covered during different courses separately. On the other hand, the book will be useful for network specialists who would like to understand what are the basic categories of thinking for management or marketing staff. “
