Guidelines and concepts Use experience gained at FLASH FLASH is a small version of the XFEL Developed and test at FLASH (partly PETRA) be ready when XFEL (construction) gets ready Develop generic recipes and frameworks ensure portability (FLASH  XFEL) Implement on middle layer where possible have common interfaces & exception handling reduce load on front ends to e.g. avoid “wildly running FBs” Accelerator Controls Conceptual Design Review, 14.
