  Problem How to securedelivery order in the long-running- delivery-pipeline as well as enable concurrent pipelines executions? Example: ● SCM check out can run concurrently, but the changelog computation requires that the check out of the earlier build has completed ● Sending out an e-mail with test results requires info about the previous build, so that we can decide an e-mail is necessary or not ● Rolling out database schema updates ● Delivering incremental changes to users Image source: http://desigeek.com/blog/amit/2010/08/08/race-conditions-explained/

  Idea Use Jenkins CheckPointAPI in order to sync pipelines implemented using Groovy and BuildFlow (potentially WorkFlow) Image source: http://delivervalue.blogspot.se/2013/06/more-advanced-build-flows-with-jenkins.html
