Encouraging your team to evaluate their peers is a proven method to improve working environment and productivity.
All peers that worked together should evaluate each other by filling a Peer Evaluation Email every month.
The evaluation is done by giving constructive comments in “Start, Stop, Continue” e.g. (Start...) checking in with better comments e.g. (Stop...) coding without a user story e.g. (Continue...) with your helpful SEO comments
