After reading some good material on accountability from medium, I decided to get you this points, hope they serve you well.
Accountability is most often used to explain one’s performance, or lack thereof, directed to someone (boss, spouse, etc.) with the expectation that the explanation will sufficiently “account” for the results. Generally, accountability is only brought up if something is lacking rather than as something we utilize to ensure success. This misses the mark, leaving accountability as something to be avoided rather than explored.
Accountability is fundamentally a state of being — a willing acceptance to be the one counted on (most often to produce an outcome) — and as a consequence, the primary action of accountability is to account for one’s word.
