You are in the role you are because you’re good at it. Sometimes that doesn’t always mean people listen to your ideas or allow you to try new things. Their intentions are probably good: doing what they think is best for the company. This is where persuasion comes into play.
When presenting an idea, just like any type of marketing, you are trying to persuade your team to use your idea. Take the skills you apply to the actual marketing and apply them to the presentation of your idea.
“Character may almost be called the most effective means of persuasion.”
Every interaction you have with your team is an act of persuasion.
