A/B testing is used far too often, for something that performs so badly. It is defective by design: Segment users into two groups. Show the A group the old, tried and true stuff. Show the B group the new whiz-bang design with the bigger buttons and slightly different copy. After a while, take a look at the stats and figure out which group presses the button more often. Code.

Journal of Object-Oriented Programming June/July 1988, Volume 1, Number 2, pages 22-35 Department of Computer ScienceUniversity of Illinois at Urbana-Champaign 1304 West Springfield Ave., Urbana IL 61801 (217) 244-0093, (217) 328-3523 johnson@cs.uiuc.edu, foote@cs.uiuc.edu Abstract Object-oriented programming is as much a different way of designing programs as it is a different way of designing programming languages.
This paper describes what it is like to design systems in Smalltalk. In particular, since a major motivation for object-oriented programming is software reuse, this paper describes how classes are developed so that they will be reusable. Introduction.
