Guide to Agile Practices Definition In consultation with the customer or product owner, the team divides up the work to be done into functional increments called "user stories".

Features - Practical Game Playtesting: A Wii-Based Case Study [Sidhe's Griffiths discusses in depth how the GripShift developer playtested, and then took that feedback to improve, their Wii version of the recent Speed Racer game, from Wiimote tweaks to difficulty changes.] Playtesting a game for the very first time is an incredibly daunting task. I'm not talking about all the preparation that goes into it; I'm talking about the abundance of negativity that is bound to be thrown your way. The first time players get their hands on the game always results in problems -- and when it comes time to write up the report, I realize with each soul-destroying point that it's my job to then present this information to the developers.
