Blocking task
Accepted answer
As far as I can tell there is a new feature mentioned in RTC 6.0.1. See https://jazz.net/downloads/rational-team-concert/milestones/6.0.1M3?p=news#blockedcardsconfiguration and https://jazz.net/help-dev/clm/index.jsp?re=1&topic=/com.ibm.team.apt.doc/topics/t_plan_kanban.html
I am not aware that blocking is supported prior to that.
