The SHRM website makes a sweeping declaration about its vision: “Our vision is to be a preeminent and globally recognized authority whose leadership, perspective, resources and expertise are sought and utilized to address the most pressing, current and emerging human resource management issues.” The ATD website has a similar mission pronouncement: “Our mission is to empower professionals to develop knowledge and skills successfully.”
I added the underlines to highlight the memorable superlatives that express organizational identity rather than association tasks. I picked SHRM because they are arguably the best-known association for HR professionals, and ATD (formerly ASTD) since they are the best-known association for HRD pros. As such, they set the standards for their respective members and professions. But, this piece is not about SHRM or ATD. It is about your mission and providing a service experience congruent with that mission/vision.
