Brag Docs
Julia Evans' blog post on Brag Docs is an excellent primer for why Brag Docs are essential, especially for remote teams. Opening a shared space with your direct report to list accomplishments and impact makes quarterly/yearly check-ins significantly more accessible and allows people to take ownership of their contributions.
I also set the expectation that I would place things in my direct report's brag docs--praise received from peers, for example, would go into the brag doc.
The title "brag doc" causes some consternation related to the stigma around celebrating your accomplishments and owning your impact. Some alternatives might help: hype doc, atta boys, or go full corporate with "performance review self-assessment."
