Communication is the key to solve impediments

As a SM I have to admit sometimes I'm too proactive trying to solve impediments and tend to take decisions quickly. Fortunately I can count on a group of great professional developers, designers, consultants, managers and I can say with pleasure that most of the time I can solve problems just let the right persons talk each other at the right time driving the discussion on the point of interest.
Communication is the key to open most of the locked doors.
