Hardly we are without information, in a short space of time we have access the diverse contents. As well as in this example, and as in as much others, a product has helped the world of the capital if to become still more powerful, if to become a world-wide success still more. This product is the Softwares. Softwares is used by the most diverse areas of knowledge. Everything that if understands as form to optimize processes, activities, relationships, can be managed and be improved using informatizados systems. From there the great importance and the basic attention that must be had in the organizations that they search to develop this Softwares in the best possible way, making with that this world supplied capital it either fully. For this objective, with intention to reach full satisfaction of the customers and better yield of the desenvolvedoras companies, it is that we go to analyze an area of study that comes alavancando this market, the Engineering of Softwares. 2 – Theoretical recital softwares is part of a context called computational systems, that are composites of the following parts: software, in the case, programs of computer, structures of data, and associated documentation that serves to accomplish the methods, procedures or process of logical control; the hardware, that is the electronic devices that define the capacities of a computer and electromechanical devices that offer functionalities to the external environment; staff, users/operators of the hardware and software; data bases, a collection of information organized systematically, had access through software; documentation, manuals, forms and other documents that can assist in the knowledge of the use and operation of the system; procedures, the rules that specify the specific use of each element of the computational system. (Engineering of Software, Chapter 6 – BASIC CONCEPTS, Prof Vitrio Bruno Mazzola, INE/CTC/UFSC) to analyze what we understand today as development of Softwares, we have that to understand as and why the first steps of the professionals of the digital world had been given.
