Haven&#x27;t used 15five, although it looks to me like a report form for weekly challenges, issues and so on - Text-based, way longer to fill in, yet probably more detailed.<p>Retroospect on a basic usage takes like 15 seconds to fill weekly and only tracks 5 basic data points, allows anonymity and produces charts, breakdown reports, etc... it&#x27;s a more lightweight product, demands less from users and cost less - quite different kettle of fish.<p>In my experience teams tend to stop using products that demand too much after little time unless you enforce their use, although these tools are probably a better choice if you want in depth reports.
