wig differentiation 

When managers, leaders, or speakers use an atypical method to draw attention to themselves, their message, or their personal brand. This can be a effective method when the intended message is received and reinforced. It may also fail if the presenter does not have a firm grasp on how humans learn and retain information. Either way, it's usually very entertaining.
My boss is into making sure our Team is fully engaged and learning about what matters. From what I saw at his last presentation, he's killing it using wig differentiation.
