When I first introduced "Jam Sessions" to our team - dedicated time for open discussion about technical challenges - I got more than a few skeptical looks. But after a year of running these collaborative sessions, they've become our most effective tool for breaking down knowledge silos and building deep technical understanding, as team members wrestle with concepts out loud and collectively work through complex scenarios. We've discovered that when engineers have to explain solutions in their own words, it not only reveals their true grasp of the concept but also highlights gaps in our documentation and training materials.

What methods have you found most effective for uncovering and addressing knowledge gaps in your team(s)?
