A confident voice can ask a sharp question at the wrong moment and close a room down. In a meetup, the cost is one nervous speaker and a room that goes quiet. In a company, the same habit compounds, meeting after meeting, until the same few people decide what the team is allowed to say out loud.
You see the pattern at conferences first. The people who are confident keep speaking. The people finding their voice hold back. Over time the room narrows. The same voices return, the same ideas circulate, and the different takes never get a hearing.
When working with clients, how teams communicate tells me more about the culture than anything else.
Successful teams should communicate like a team fielding in a game of cricket who work together towards the same goal giving each other support and encouragement.
By sharing information about the batters, pitch, conditions and strategy, a feilding team agree on a plan on how to bowl and position themselves.
