Create a herd mentality that serves your change agenda

Post a public list of those complying with your changes
Make it a policy to write down the names of people who are actively making the changes you’ve requested. Then post the list on a wall or the company’s online portal. This will create social pressure on those who haven’t yet embraced the changes. They’ll feel left out and do whatever it takes to fit in.

Create the impression that others are already on board with your goal
If you want to establish a new behavior in your local community, get a few people to act as if they support the change. For example, encourage a few change champions to publicly promote your agenda through TV or radio ads. Once people realize that others are on board, the behavior will spread widely.
