What you're describing is Enterprise(tm) software. Some consultancy made tens of millions of dollars building, integrating, and deploying those things. This of course was after they made tens of millions of dollars producing reports exploring how they would build, integrate, and deploy these things and all the various "phases" involved. Then they farmed all the work out to cheap coders overseas and everyone went for golf.

Meanwhile I'm a founder of startup that has gotten from zero to where it is on probably what that consultancy spends every year on catering for meetings.
