I am an app developer who interfaces with c-suite executives weekly.
Every time I get into the weeds with them I lose their attention. EVERY time. They don't care about the technical aspects of my solutions, they care about what it means to their customers functionality, the price they pay for the solution or the time it takes a product to be delivered. So I put things in those terms. I NEVER get very technical anymore unless it's absolutely required.
In short, summarize your choices, decisions and solutions in high level language from the perspective of what they care about -- that's it.
