System-Requirements vs. Software Requirements Specification. How to setup

Hello to all.

I'm working with in an existing requirements environment ( Toplevelrequirements - Systemrequirements - Softwarerequirementspecification - Detailedimplementationrequirments ) realized in Doors and we have a lot of problems probably due to some misunderstanding requirements-engineering as well as using Doors in the right way as well.

Main problems are:
- how to keep roughly 5000 requirements alive/managable?
- changes/suspect-links management is a nightmare
- all is attributed as requirement ( therefore nobody knows who is responsible for testing)
- What is a real requirement, what is an implementation detail: total confusion
- What is the difference between a specification and a requirement.
- Where to place the HW-/SW-Interface and is it a requirement or a specification?
- .....

I feel the complete requirements-engineering and -management-process begins to crash.

My Question is:
Is there any introductory material available which addresses at least some of my problems?

I surfed the internet now for a weekend and I was not really successfull in getting answers to my "needs".
Thanks in advance for some discussion

If your really keen to become an expert in this area, join a Systems Engineering society such as INCOSE http://www.incose.org where you will have access to some of the best minds on the subject matter of Requirements Engineering & Requirements Management (AKA Specification Practices).

Here are a couple of sites to get you started:

http://www.jiludwig.com/ Interesting site, good for entry level into this subject matter, the table of contents (TOC) on the home page is not in the best reading order, start with the "Walk the RM Trail" hyperlink in the TOC, follow this with having a look at the "Requirements Management Plan" hyperlink, then just browse around the site.

http://requirementsengineering.info/ - This site promotes a book that is one of my more popular references and has some DOORS examples (Used to be a book that Telelogic handed out freely, but alsa no more since being acquired by IBM).
