Is a job group the same thing as a job family?

Understand how CompetencyCore uses the term "job group"

Job Family is an HR term. Jobs that share a common set of competencies, perform common functions within the organization, and form a logical career path typically belong in the same job family. Job Group is a CompetencyCore term. Job Groups are used to organize jobs for any reason. You might group jobs together because they’re part of the same department. But as a best practice, we recommend setting up Job Groups on your site to mirror the Job Families in your organization.
