What is COCOMO (Constructive Cost Model)

Information technology is critically dependent on a number of technological and human factors. Software engineering processes are multi-sided; they include customer and developer parties. Conceptual misunderstanding by either party often results in the products which do not meet customer's expectations. This misconception of the software product scope usually leads to a crisis of software product delivery. To adequately manage and efficiently respond to this crisis, the authors recommend using software engineering models, methods, techniques, practices and tools. Software engineering is a discipline which started in the 1960s as a response to the so-called “software cri-sis”; it combines technical and human-related skills. To manage the crisis, the authors suggest architecture patterns and instantiate them by implementation examples.
