While you will probably get this through natural play, the easiest way to get it is when you complete the first mission involving Koller (one of the first two missions you receive upon arrival in Prague) your augmentations will be reset back to "Factor Zero" and you'll likely have somewhere around 10+ praxis points to spend. Save the game, then choose one of the shorter branches and fully upgrade it to unlock the achievement. Once you've gotten the achievement, you can reload and make your choices more strategically.
