Support is a broad word that can mean approval, public backing, practical help, or funding. If you need to stress acceptance of a plan, buy-in may be more precise. Neither word proves that a person has promised time or money, so state that commitment on its own.

Learn "Buy In" in depth →What "support" doesn't tell you
"Leadership supports the new roadmap."
Does that mean leaders approved it, gave it a budget, or agreed to defend it? "Support" alone does not say, so add the action if the difference matters.
What "buy-in" adds
Buy-in means acceptance of an idea or plan, and at work it often suggests that people are willing to help with implementation. Still, it does not name a formal decision, an approved budget, or a set level of effort.
"We have leadership's support, but we still need buy-in from the regional managers who actually control headcount."
"Getting buy-in meant walking each VP through the numbers individually before the all-hands, not just presenting it cold."
The first sentence names the managers who control the choice. The second describes outreach, not proof that any VP agreed. To show what "supporting" means, report what people accepted and what action, if any, they authorized. Buy-in does not replace consent, a contract, a policy, or approval from the decision owner. It is common work jargon. Plain words may be clearer across teams and languages. Credit concerns as well as support, keep evidence of the decision, and report outcomes without promising success.

Instead of: "Do we have support for this initiative?" Say: "Do we have real buy-in for this initiative, or just polite agreement in the room?"
Instead of: "Most stakeholders support the change." Say: "We have buy-in from most stakeholders — three teams have already reprioritized their roadmaps around it."
