In a report, it is usual to have introduction, perhaps a summary, body, conclusion. The introduction says in as few words as makes sense what the report is about. The body isn’t really a discussion, it is laying out things for examination. The conclusion weighs up the things that were examined, to come up with one or more conclusions. The summary is put into big reports so people only need read the intro and summary to see in general what the body and conclusion will say, and leave it up to the reader if he wants to read the whole thing.

I always start off with ” In this paper, I argue …. I will begin with the discussion of … then, I will show why ….

then again, “we” should be ok too… post the whole intro…its hard to tell from just one sentence.
