Today I read a blog by Daragh Farrell at Thoughtworks. Daragh tells the story of a team that had returned to holding retrospectives and expresses amazement at the positive effect of the ritual on team development. Retrospective boosters (like me) tend to stress the role of retrospectives in process improvement and product quality because those have a more direct impact on ROI. I'm glad to be reminded of the more subtle contribution of retrospectives to accelerating team development. High performing, self-organizing teams also contribute to the bottom line through increased productivity, innovative thinking and lower absenteeism and turnover. Retrospectives foster team synergy. Thanks Daragh, for telling your story.
