This is not HES, it's the Graduate School of Education https://www.gse.harvard.edu/ppe/professional-education-online-programs
Discount if you enroll with a buddy or two?! Wow, I hadn't heard of that before. Their modules emphasize team-based projects, so what an AWESOME way to encourage real team-based learning through distance learning. BYOT $2,250 per person/module $1,995 per team member/module (teams of 3+)
These programs are cashcow for them. I looked at the Cyber Security Certificate; the price tag is $52,000.00.
My bad, it is Business Analytics...why I keep thinking Cybersecurity. "An Online Business Analytics Certificate Program for Leaders" URL: https://analytics.hbs.edu/
