When looking for mediocrity, when your organization is searching for profiles on the trailing edge: almost unqualified and unsuited to the position. When the requisites of finalist candidates applying to a managerial position are justified with difficulty, then excellence values nought.
If your organization is doing selection and promotion process in the former way is going to discard linchpins.
When looking for profiles in the lower limit, that is in the lower 15% percentile, an outstanding resume's value becomes zero. Managerial mediocrity is shown to have strong, negative impacts on workplace productivity.
Be authentic and focused about what drives and energizes you and makes you a strong person within your organization.
