Information system building blocks

Can someone please be so kind as to please describe scope definition, problem analysis, requirements analysis, logical design, and decision analysis phases in terms of information system building blocks. I would really appreciate it greatly, I really need to know the in's and out's of this for a project I'm working on for class. If someone could help me with an detailed response/answer it would help me dearly, god bless!

P.S. Sorry for the long question, its just that its a multiple part project and my professor is really fond of giving out tons of work, once again plz help anyone when u can, thks!

I'm really desperate here, can someone plz help me, any information anyone has would be greatly appreciated not looking for anything lengthy just some sort of response would be nice.

Well, so much for getting help *sigh* thanks for nothing guys, I know it was a lot but jeez! someone could have answered just half of the question, I would've settled for that *sgh*

Very short answer:

In software R&D these make up design specifications. All separate documents that link to the testing phases of the software. A technical writing group can point to how to construct each document.

Some of the documents address compatibility issues. Luckily Microsoft and other companies did the work for you if you use their products. Don't always expect a straight answer from academics as many have spent years in the classroom. Important (maybe) but experience trumps book learning.
