This article examines the efficacy of an ethics discernment process in the organizational context, a practice referred to in the paper as "mission due diligence." This type of ethics discernment is a structured process intended to awaken the ethical concerns that a particular issue raises within moral agents and to give voice, directly and indirectly, to those who will be impacted by, and responsible for, strategic decision making. The efficacy of this particular ethics discernment practice is contingent upon several realities, including, but not limited to 1) the timing in which it is undertaken, 2) the degree of importance and relevance attributed to it, and 3) the skills of the person leading it. This case report examines how this process was used to highlight and address the ethical issues related to a new hiring policy, namely, a mandatory nicotine screening test for prospective employees in the healthcare context.
