My choice would be critical & analytical thinking, which is usually high priority on a manager's person specification (HR context).

Outline from http://www.studyadvice.hull.ac.uk/documents/Criticalthinking...
"Critical thinking goes hand in hand with analytical thinking. For Cottrell (1999:188) analytical thinking involves the following additional processes: • Standing back from the information given • Examining it in detail from many angles • Checking closely whether it is completely accurate • Checking whether a statement follows logically from what went before • Looking for possible flaws in the reasoning, the evidence, or the way that conclusions are drawn • Comparing the same issue from the point of view of other theorists or writers • Being able to see and explain why different people arrived at different conclusions • Being able to argue why one set of opinions, results or conclusions is preferable to another • Being on guard for literary or statistical devices that encourage the reader to take questionable statements at face value • Checking for hidden assumption"
