370 views

Published on

November 17th 2015, 11:00 – 12:30 – An outline summary of potential use cases to demonstrate the functionality of the prototype of resilience.io. The cases outlined at this meeting are based on inputs given by the GTG at the September meeting. Use-case development will be collaborative with the GTG and the final selection of use cases will take place in January 2016.
