You can sound like a maverick if you challenge conventional wisdom. People will pay more attention when you make a clever yet counterintuitive observation.
For example, everyone knows the importance of listening to the customer. But if you're proposing an idea that goes against the customer's wishes, cite Henry Ford's line, "If I'd asked my customers what they wanted, they'd have said a faster horse."
If your team gets caught up trying to overanalyze something, step back, simplify and start talking plain English. Suggest that your colleagues follow investor Warren Buffett's advice, "There's something about smart people explaining ideas to an orangutan that makes their decision making better."
