Three short whistles for 'up'

There's a large crane onsite at a housing construction site nearby today. 

While the set-up and set-down of concrete slabs and wooden piles can be a visual distraction, it's the auditory, the sounds, that are getting my attention. 

There's great deal of trust, communication, cooperation, focus and engagement that's required among the team - all conveyed via hand signals and ... a little silver whistle!

One long whistle... 'lower'

One short whistle... 'stop'

Three short whistles ... 'up'

With this quick visual guide I was off and running, watching what was happening, learning quickly from the visuals on the guide and confirming via the sounds I was hearing.  

What auditory or sound signals do you give the people in your team? (applause, cheers, verbal confirmation or encouragement, verbal rewards...)

What quick visual guides do you use so that people are up to speed quickly on what to do, when, and how? (noticeboards, flyers, post-it notes, big picture visions, the visual storyboard, process maps, status or kanban boards...)

Keep it simple. No need for big bucks, fancy design and a mega-production with massive timelines! 

What simple tools can you use to convey information and engage quickly and clearly today?

One long, two short whistles ... slew (or veer) right!
