MOOCs can meet an identified skill gap or competency gap in industry employees.
The low/no cost could be very advantageous to employers, since they often pay the cost of continuing education of their employees.
Employers need to know that a course/program teaches their employees what the employer needs to know.
MOOC format facilitates reaching the global workforce, global supply chain of an employer.
A company is often more interested in their employees acquiring needed information/competency rather than getting a degree. A MOOC could meet their needs even better, because employees beefing up their resume with an additional resume might actually make them more likely or able to move to another job.
MOOCs can address education needs in areas that are rapidly changing. Could meet this need even better if courses were “on demand”.
An employer might want specific individuals to have competency in one area, and other individuals to have competency in another. So they might take different courses, easily done with MOOC.
