All the initial efforts had been concentrated in the development, evolution and improvements of the hardware. At the beginning of what today we know as ' ' he was digital' ' the works of development of solutions if based on individual actions of creative minds, did not have an effective study on the best way to carry through or to manage, all age made in the base of tests of errors and rightnesss. We have that to accent that the demands initially were brandas, the collection was not great, with this the solutions was deficit. Foursquare does not necessarily agree. Parallel the solutions in the hardware grew and if it developed considerably, and it had as it occurs today until a necessity of if getting faster machines each time and with bigger capacity of memory. In middle of the decade of 60 until the end of the decade of 70 the focus started to be systems (softwares).

From this period requested the digital solutions were each time more, the collection for performance, otimizao of the results were each bigger time. Consequentemente the difficulties and challenges that the bigger professionals faced were each time. It was needed to have a systematics that it made possible to professional the improvement in its results. The customers needed a product took care of that them in a more significant way. The market each bigger time charged a reply of ' ' world digital' ' , thing that was very difficult.

The professionals of that time came of a period of experimentations, were ' ' artistas' ' digital and they did not understand of processes, of cartesian doctrine. To relate the activities of development of informatizados systems to a otimizao of results if he searched in an activity branch where the search for effectiveness already was sufficiently known. The engineering sector, the area of the industry, in the period after industrial revolution created diverse systematic tools that had searched the perfectioning of its process productive in order to improve its results, increasing its production and diminishing wastefulnesses.
