1. Pretend you've already failed.

Guy Kawasaki, a business guru and best-selling author, advises business leaders to gather their team before making critical decisions such as launching a product or service. He suggests seizing these moments to say, “Let us pretend that our product, our company failed. Now, what are all the possible reasons?” The reasons may include lack of distribution, an unsophisticated sales force, buggy software, or unreliable cloud services. According to Kawasaki, the point is to get people imagining everything that could go wrong, so they can take steps to remedy problems before they happen. In other words, he says, “Conduct a pre-mortem so that you never have to conduct a post-mortem.”

2. Keep it Novel.

Richard Branson, Virgin founder, writes about adding novelty to freshen up meetings. He invites thought-provoking speakers in diverse fields from astronomy to nanotechnology to get groups thinking in “new, exploratory ways.” And he holds discussions in innovative spaces. Though you may not possess your own private island like Branson, he suggests that anyone can leave the desks behind and head out to the park, because a ”change of scenery and a bit of fun does wonders for getting people thinking differently and loosening up!” (Also see Nilofer Merchant's TED talk on walking meetings and Jason Yip's guide to stand-up meetings.)

3. Pause.

Clay Shirky, an author who covers the social, economic, and cultural effects of the Internet, has a bit of advice for those who charge off to meetings in a frenzied, preoccupied state. Shirky learned an important lesson when he was a student in London. To get into a receptive frame of mind for his studies he would pause during his walk over the river Thames on his way to the lecture hall. He wrote, “Crossing this majestic river was like passing from one world to another. I liked standing on the bridge and enjoying the flowing stillness in-between.” Later, Shirky applied this meditative technique to his workplace meetings. He'd imagine the walk from his desk to the meeting room as a similar journey that gave him time to reflect as he prepared for the meeting. “Time taken to pause,” he wrote, “even if it is a few seconds, can be valuable. It could be the difference between a good idea and a great idea in your next meeting.”
