The Spryng platform has published an online course. It presents the material that I had in our Signifier Basics course in addition to covering the entire sensemaking life cycle. It also shows you how the platform can support each of the sensemaking phases.
For a $129 month subscription, it is an excellent value to learn the process and test out the platform. All of the course details can be found here.
You can also purchase the course for $699 separate from a platform subscription. With this approach you get assignment feedback and an Explorer account. Here are those details.
It is estimated to take around 30 hours to complete the course.
