Scrum - Cialas(TM) for a manager's CV[1].

1 - Don't take Scrum if you are responsible for delivering a product. To avoid long term WTF, seek another job if your stand ups last more than 4 hours. Scrum does not prevent the spread of defects. If you have any sudden decrease in productivity, stop taking Scrum and call your developers immediately.

Why tell your development team you are incorporating Scrum? Because, sooner or later, when the moment is right, you can spring it on them and get the keyword on your CV.
