Marketing involves promoting the practitioners’ skills, competencies, and expertise to obtain organization development (OD)-related work, assignments, or projects. McLean listed many approaches practitioners can use for marketing: word of mouth, networking, websites, printed materials, request for proposals, visibility, contract agencies, and doing pro bono work. Networking can be developed through participating in professional or community organizations, current or former associates and coworkers, friends and family, and former classmates, instructors, or professors. It is strongly recommended for practitioners to have a high-quality and professional website that includes their personal information (i.e., name, photo, contact information, education, and qualification), areas of expertise, list of past clients, client testimonies, brief description of completed projects, and publications. OD interventions can be aimed at different levels: individual, small group, intermediate-sized, large scale, industry-wide, and community.
