  Com­plex con­trol sys­tems often re­quire com­plex tools to fa­cil­i­tate daily op­er­a­tions in a way that as­sures the high­est pos­si­ble avail­abil­ity. Such a sit­u­a­tion poses an en­gi­neer­ing chal­lenge, for which sys­tem com­plex­ity needs to be tamed in a way that every­day use be­comes in­tu­itive and ef­fi­cient. The sen­sa­tion of com­fort and ease of use are mat­ters of er­gonom­ics and us­abil­ity - very rel­e­vant not only to equip­ment but es­pe­cially soft­ware ap­pli­ca­tions, prod­ucts and graph­i­cal user in­ter­faces. The Con­trols Con­fig­u­ra­tion Ser­vice (CCS) is a key com­po­nent in CERN's data dri­ven ac­cel­er­a­tor Con­trol Sys­tem. Based around a cen­tral data­base, the ser­vice pro­vides a range of user in­ter­faces en­abling con­fig­u­ra­tion of all dif­fer­ent as­pects of con­trols for CERN's ac­cel­er­a­tor com­plex. This paper de­scribes the on-go­ing ren­o­va­tion of the ser­vice with a focus on the evo­lu­tion of the pro­vided user in­ter­faces, de­sign choices and ar­chi­tec­tural de­ci­sions paving the way to­wards a sin­gle con­fig­u­ra­tion plat­form for CERN's con­trol sys­tems in the near fu­ture.

  CERNs Ac­cel­er­a­tor Fault Track­ing (AFT) sys­tem aims to fa­cil­i­tate an­swer­ing ques­tions like: "Why are we not doing Physics when we should be?" and "What can we do to in­crease ma­chine avail­abil­ity?" Peo­ple have tracked faults for many years, using nu­mer­ous, di­verse, dis­trib­uted and un-re­lated sys­tems. As a re­sult, and de­spite a lot of ef­fort, it has been dif­fi­cult to get a clear and con­sis­tent overview of what is going on, where the prob­lems are, how long they last for, and what is the im­pact. This is par­tic­u­larly true for the LHC, where faults may in­duce long re­cov­ery times after being fixed. The AFT pro­ject was launched in Feb­ru­ary 2014 as col­lab­o­ra­tion be­tween the Con­trols and Op­er­a­tions groups with stake­hold­ers from the LHC Avail­abil­ity Work­ing Group (AWG). The AFT sys­tem has been used suc­cess­fully in op­er­a­tion for LHC since 2015, yield­ing a lot of at­ten­tion and gen­er­at­ing a grow­ing user com­mu­nity. In 2017 the scope has been ex­tended to cover the en­tire In­jec­tor Com­plex. This paper will de­scribe the AFT sys­tem and the way it is used in terms of ar­chi­tec­ture, fea­tures, user com­mu­ni­ties, work­flows and added value for the or­gan­i­sa­tion.
