I can understand the inclination, but actually I /do/ want the details, because without the details I cannot consider and measure if the change proposed is a reasonable pathway to help manage the class of problem. Many times, people in organizations while well-meaning are siloed and focused specifically in their own niche and therefore will propose changes that cannot be coherent in any holistic manner across all the parts of the organization that would need to be affected by the change. That means you /do/ need to understand the details, and also have a big picture view.

The executive is there to help with the big picture, but you can't see the big picture if the canvas is blank.
