KRA (Key Result Area) is a set of feasible strategy alternatives for positively impacting strategies, can then be incorporated into the organization’s long term strategic plan with appropriate responsibilities and time frames assigned. This is followed by a job description which summarizes the essential responsibilities, activities, qualifications and skills for a role unique to your organization. You may to develop your own job description and KRA for your designated individuals.
