The biggest thing is that it shows cradle to grave traceability between the initial parent requirement and the lowest level, or what we call a CID, a critical item development spec. You can establish your verification plans in DOORS, and then as you get test results, you can put them in DOORS as a link or as a pointer to where that specific test resides on a company database. Then you can also write compliance rationale and add a column for coding, like pass, fail, green, yellow, red, meets, does not meet, partially meets, or whatever scoring criteria you want to use. Like I said, the best thing about it is that it provides you that visibility of your verification, allowing you to know how close you are to your pre-production activities, prototyping, go ahead, or whatever it is.
