It's been a couple of years since I retired from Aplia. Before I forget, here's some of the values that helped make Aplia a great place to work.
Hire people that are smart and nice.
They can learn everything else.
Get to know your users.
Figure out what would make life better for them.
Design the best product for students and instructors.
Everything else (sales, profits, ..) will follow.
Keep the design simple.
White pixels are free!
Build a little. Test it with users.
Then build some more. Then test it again.
Measure it. Fix it.
Then measure again to see if you fixed it.
Give bugs top priority.
Don’t build more if you have bugs.
Avoid add options for this and that.
Add an option, go to jail.
