When your Agile coach simply throws the ‘jargon’ that you do not understand ??? and then pretends that this ‘jargon’ is way above you “mortal” souls, you are entering the world of “Fly-by coaching”
The coach can run this routine once or twice or even thrice if lucky, but the team members can quickly figure out the reality (thanks to google!) and will pick up that the coach is simply faking his stuff and is not really strutting his stuff.
When asked for How do you actually show the stuff (as put up in the jargon)? – you will see the coach either disappearing or simply attending to prepare some management reports.
You should realize that indeed that you have a ‘Fly-by’ Coach in your mix, and you can almost predict the disappearing act!
