Anyone know the 90% principle

[Blackjack2000]

I remember hearing somthing like "90% of the cost of engineering is spent squeezing out a 10% performance gain"

Has anone heard this and know the exact expression or principle, or have a link? Btw, I'm checking Google, but it's not an easy phrase to search. Any help is appreciated.

You butchered that good.

Diminishing marginal returns.

lol, I bet I did, it's been years since I heard it.

I've always heard it as the 80/20 rule

Yeah, I'll probably have to use that. It's for a ppt presentation, so I think the whole 90% thing would have resonated more, but the law of diminishing returns should be good enough.

try 80/20 rule on google

Don't forget the complementary statement that by cutting back 10% of performance, you can save 90% cost. :-D

Yep, that did it. Thanks a lot.

It's such a true model. I love it.

i've heard this works with software packages too, 80% of the people only use 20% of the features

It's called Pareto's Principle, and it's 80/20 as you've already figured out.
