2.9.3

aśvasadharmāṇo hi manuṣyā niyuktāḥ karmasu vikurvate //

THOSE who are possessed of ministerial qualifications shall, in accordance with their individual capacity, be appointed as superintendents of government departments. While engaged in work, they shall be daily examined; for men are naturally fickle-minded and like horses at work exhibit constant change in their temper. Hence the agency and tools which they make use of, the place and time of the work they are engaged in, as well as the precise form of the work, the outlay, and the results shall always be ascertained.
