Approach--DMSG define requirements & pass on to WGISS WGISS can better understand scope of our problem Different from current WGISS scenarios (“use cases”)?

Some differences (my preliminary perception) Many DMSG “use cases” high level, poorly defined Often users doesn’t know what they need Requirements are diverse Requirements are often specialized Users speak a different language

DMSG requirements very different, I believe!!DMSG requirements very different, I believe!!
