Identify The Knowledge Gap.
That's the space between what people know and what they don't know. Instead of assuming what they know, start determining what they need/want to learn in order to fill in this gap and ensure clear communication. What may seem old or common to you is new to them. Use questions up front to uncover what's needed to fill in the gap.
Example: "Just so I don't sound repetitive, how familiar are you with-?" "Web Image Monitor can do this for your organization, this is why -------."
