This chapter is a work about the development of a model for the engineering requirement based on ontology. The development patterns are not used efficiently, especially for non-observance of the principles of requirements engineering. The overall objective of the chapter is to propose the use of an ontology based on the artifacts of software requirements engineering and can be used on any project developed in any organization. The method uses experimental procedures, which are held in experiments with real situations in a project in progress at a reputable company in the development of hardware, but that currently covers its business in the software services industry. As a result, there is an improved understanding of software requirements, as well as its trace within the scope of the project, i.e., one can easily traverse the model and identify all the artifacts impacted by the change.
