I have been searching about a solid definition, references based, about what is a technical report and which one are their constituent parts. Actually, I am in the field of Computer Science and I have seen that information is rather obscure.
I have seen that in some institutions, a technical report is a non-peer reviewed document in which a researcher states his experimental advances, discussion of results and conclusions of an on going project. The format sometimes in near to a thesis. In some other institutions the technical report has the form of an academic paper, but the parts mentioned before are almost the same.
So at this point, I will like to ask if there is any recommended and reliable sources of information, such as articles, that defines what a technical report is and their common parts; of course, mostly oriented to the field of Computer Science.
