When if it joined this doctrine of engineering with the empirical activity of the primridos ones of the digital age if it conceived the Engineering of Software. The concept of Engineering denotes an action to create, to analizar, to consruir, to develop, to follow, to keep. Software is a personalized product. No matter how hard in the market some companies carry through similar tasks, no matter how hard professional systems ambicionem that give seemed solutions to them, the desenvolvedores are charged by taking care of specific yearnings of its customers, all want a particular solution, a personalized assistance, what she demands a routine that makes possible the professional at the same time to take care of to the demand reducing the open assembly time and wastefulnesses.
This question demand a still more imperious search the use of routines that systemize the work of development of digital solutions. As this product is not concrete, it is not easy of mensurar, the tools of control it has that to be rigid and controlled. Amongst the definitions of Engineering of software we can detach the following ones: ‘ ‘ Software is the creation and the use of solid principles of engineering in order to get software in economic way, that is trustworthy and that reais’ works efficiently in machines; ‘ (Friedrich Ludwig Bauer, Engineering of software, 1969) ‘ ‘ The establishment and use of solid principles of engineering so that if it can economically get a software that is trustworthy and that reais’ functions efficiently in machines; ‘ (Fritz Bauer – 1969) ‘ ‘ Set of methods, necessary techniques and tools to the production of software of quality for all the stages of the cycle of life of produto’ ‘ (Krakowak, 1985) In order to understand the difficulties found for the companies of development of softwares in its search in improvements its results, we can analyze some distinct stages of the process: – Definition of the target of the project – Development of the project – Accompaniment – Improvements difficulties start soon at the beginning of the activities of development.
