The best way to ensure that my manager understands my ideas and suggestions is by clearly articulating my ideas and suggestions in the most concise way possible. I like to provide concise and organized information, which will allow my manager to quickly and effectively comprehend my ideas. I also like to present information in a visual form, such as charts or diagrams, as this can help to make my ideas and suggestions easier to understand. Finally, I always follow up with my manager to ensure that they understand my ideas and suggestions.
