Designers Know Best • Jon Callas • CTO/CSO • PGP Corporation
Testing Isn’t All Bad • Testing has its place • It can tell you what color to make a button • It can tell you where to put the button • It can tell you if the customers want to fit fire nasally
Testing Can Impede Progress • All users know that change is bad • People like what they are used to • They forget how much they hated what they have now
Innovation is Change • If training is required • If something is new • Testing will show that it sucks
Design is an Art Form • Like writing, painting, film, etc.
Testing Can Be Bad • What happens when they want fire to be fitted nasally? • I do too! • Breathing fire would be so cool!

This is Especially True in Security • HCISec is hard • That’s why we’re here • That’s why this is a fun discipline • At least we know our limitations
We’re Designers For a Reason • Any coherent vision is better than no vision at all • Testing can help refine coherency • Testing can help us break out of bounds • When you run out of red, blue often works
Ultimately • Every useful thing was designed • Even the one-button mouse • All that we now love once sucked
