As a leader of managers, you should be evaluating your managers on the quality of their decisions…not on how effectively they execute your decisions.
Managers should not be asking you to solve their problems. Instead, you should encourage them to share the nature of the problem, identify 2-3 possible solutions, rank the solutions, then explain their logic for the solutions and rankings.
This approach holds your managers accountable, allows you to evaluate their approach to resolving challenges, and affords managers the benefit of your wisdom as you reflect on the solutions they have offered.
Be intentional about it…
