i hope you make this comment after having read the q a question  otherwise i am gonna have to go back and make sure we are crystal clear  technical assessment is hard  it requires intimate knowledge of the project under scrutiny  it is difficult to agree on and imposes a policing burden that no one is prepared to take as busy as we are  people overlap is the next best thing  assumed that we trust the technical judgment of the people we work with  having established a longstanding relationship with them  sure  people can move on  if the project has not reached critical mass and it rots  it is fair to remove unless someone else is prepared to step in and keep it alive and well  it s just the nature of the proverbial bus effect
