This evolution takes place individually for each requirement, in a very particular way, because it depends on the level of understanding that the requirements engineer reaches in relation to it. How, then, to monitor the evolution of each software re- quirement? How to know the quality of each software requirement? How to measure the level of understanding and difficulty that the requirements engi- neer has in relation to each software requirement? This paper aims to present a proposal to answer these questions through the use of an instrument devel- oped specifically to assess and reveal the quality grades of each software re- quirement and also to assess and reveal that the levels of understanding and of difficulty of the requirements engineer is in relation to each software require- ment. This instrument was called the Hermeneutical Theodolite of Require- ments, which also can be applied to evaluate that the levels of understanding and of difficulty of the requirements engineer is in relation to the domain of application, essential input artifact and primordial to the specification of the requirements of software.
