Project business is a vital and rather new subject which needs more theoretical corpus and concepts validated by research. It is essentially different from traditional trade with goods and services and therefore requires organizational readiness as well as a new management approach. The contents of a project can vary from abstract and intangible design to concrete engineering and construction tasks. The discontinuity of project business and the uniqueness and complexity of each individual project make the marketing and delivery of projects a challenge to the firms involved. This book offers a comprehensive validated model of project marketing and identifies some key factors which influence success in project business.
