To be honest, you could have told him the your (perfectly valid) argument in a more friendly way, we're here to help each other, not to to make others feel stupid.

I'm here answering questions to help others and as a result get better myself, so I welcome criticism, but be fair.

"I know it'll hit the performance but there are cases when you need to listen to business and get things done quickly"

Respectfully - this is a case of inmates running asylum.  Your business people get to tell you WHAT - never get to tell you HOW. 

When we are willing to cut quality for the sake of speed -- we set a precedent (or it has been set, unfortunately); the BI system will show signs of wear and will begin not to perform.  No one will remember the urgency of the business request - they'll only remember we built the crumby system.

I find myself daily saying. "I'm not going to cut corners"  or "I'm going to say NO for a much bigger YES" to clients that can let me go without warning. 

MY ADVICE:  give the business the quick and dirty fix; build the proper way and swap it out ... never rest at the quick and dirty fix.
