Leader Role and Accountability Definition
Define what you're actually accountable for in your role.
Most leaders carry a job description that stopped matching reality a while ago. This page is about writing the real one.
List the outcomes you are personally accountable for. Not the tasks, the outcomes. Then list what you are only expected to contribute to, and what you have no business owning.
When the three lists are clear, most delegation and prioritisation problems get much easier.
