We use the agile development approach pretty extensively at Zoosk. We aren’t committed to a specific flavor of agile, whether XP, Scrum, or any of the other variants. For us, agile just reflects a set of values and behaviors that we try to follow as we build great software products. Each product development organization is different and agile doctrine has to be adapted to the nuances of each team’s culture. I shared some of the practices that we use at Zoosk in an article on DevX: 7 Agile Software Development Tips to Build Exceptional Products. Check it out and feel free to share comments based on your team’s experience.
