It’s difficult to come up with a good business succession plan on your own. Instead, you should involve your professional advisors. Use a lawyer (big surprise, I know) and involve your financial advisor and your accountant. You might be able to think of other advisors who should also be included in planning discussions.
Your advisor will identify things that you will not have thought about and have suggestions. Remember that they practice in this area all the time, while this is likely your first and only time dealing with this business succession issue. You should also include any other stakeholders in the discussion (i.e., family members, a spouse, anybody else who really should have a say in what goes into that business succession plan.
