Some questions we pose as consultants are 'good-looking ones'. I mean they will always draw a fulsome response. For instance, if you ask some people in a 'coasting' organisation 'what are the barriers to achieving excellence here?' they will probably give you a list long enough to make your ears bleed.
However, for every good looking question there is always an 'ugly' one just round the corner. The one here is 'What have you done about these barriers?' These are questions which must be posed and confronted, which unearth living defensive routines, and must be transformed for there to be any sustainable change.
What is your experience? What tin-opening questions do you use? What feedback have you had on them?
