Over the ten years that HSD Institute has been offering certification courses, the field has continued to grow—deeper in learning and insights, and wider in applications. What has not changed is the core content that set HSD apart as a unique and highly useful field of study. Attached here, please find the slide decks for each of the ten days of the certification course, as they were presented in Certification Cohort #27 in Minneapolis, MN, US, in 2013. They are available to assist you as you share your HSD story. Use any of these slides in your own presentations as you help others understand the power of human systems dynamics.
