What I’ve learned while listening, is that some people have a need to have their opinion heard (regardless how helpful it may be), while others are content to watch saying nothing even if they might have the critical information in order to save the situation. Some people have been suppressed in their role for so long that they haven’t the strength or have learned to say nothing, while stopping and asking ‘everyone involved’ often takes time, in some situations it can be the wisest option.
