Dependability can be defined as fulfilling commitments even in the face of difficulty. The contrast to dependability is inconsistency.

Dependability is central to the working of any organization or community. Only when we can rely on our neighbors or our team members to do what is expected can we operate in confidence. If we must consistently worry that others will fail to be dependable, we will be tentative and timid. We will feel compelled to look over our shoulder and double check everything.
