In recent years I've noticed these terms been used frequently. Morten Frost for eg.has been Performance Coach or Coaching Director for Denmark or South Africa before. Chief Coach I think is used more for China, Japan or Korea eg.Li Yong Bo or Park Joo Bong. Many people in this forum seem to think that coaches work best in a vacuum even in badminton associations, I am sure countries like England, Denmark etc. would have hierachial systems like director, chief etc (perhaps some flat and lineal ones too.) Can someone fill us in on things like : 1) What is the job description of a Performance Coach/Director 2) What is the scope of work? 3) How does it relate to other coaches? Obviously all the above will be designed on a case by case basis, anyone can give some idea?
