The 70% rule of delegation is a foundational leadership guideline suggesting that if another person within your organization can perform a task or make a decision at least 70 percent as well as you can, you should delegate it to them. This principle helps managers overcome the temptation to micromanage or hold onto every responsibility out of perfectionism. While the subordinate may initially execute the task with slightly lower proficiency, delegating allows them to build critical skills, gain hands-on experience, and ultimately reach or exceed 100% competence over time, freeing up leadership bandwidth for higher-level strategic planning.
