Call things what they are. Agree on terms and definitions that you use while collaborating. That doesn’t mean everyone goes out and buys the newest Oxford dictionary - just be attentive to the words that matter and agree to their definitions.

Even if a word like “risk” that has a pretty clear definition is being used, team members will always view things through different lenses. Defining commonly used words and terms saves a lot of time that would otherwise be spent trying to figure out what everyone is trying to say.
