Hello it's me a software developer. In my experience sprints can be beneficial when managing executives- they understand only so much can fit into 2 or 3 weeks, when you get into months the temptation is too great to keep adding tasks. I also find it useful to avoid the developer temptation to do major all at once re-writes that involve a total changeover deployment day. Instead force developers to pick off smaller parts that can go live (and thus actually get used) sooner. Similarly, sprints challenge developers to think of what they can get done and show to stakeholders quickly and get feedback. All that being said if the executives want to operate on totally fixed deadlines and ever expanding must haves for phase 1, sprints will not save you.
