  5. Access to Requirements • Requirements are stored in DOORs • http://doors1.esss.lu.se:8080/dwa/welcome/welcome.jsp • Necessary logins should have already been distributed • Please contact me if this is not the case! • For ESS DOORS is the only source of truth • Spreadsheets, Word docs., etc., have been used in the past but should no longer be trusted • Contracts will refer to well-defined baselines • So hardcopies of those baselines can be distributed with contracts

  6. Commenting & modifying requirements • The DOORS interface allows commenting on individual requirements • Start a new thread for discussion of a particular point • Continue a discussion on an existing thread • Modification permissions are tightly controlled: • Level 1: Jim Yeck • Level 2: Mats & CCB • Level 3: David McGinnis & Lead Engineers • Level 4: Lead Engineers • Modification requests should be made via the local deputy Work Package Leader • Proposals for additional requirements should also be made via the local contact person

  7. Workflow for changing baselines

  8. Two types of requirements • Top-down: • These are those that are derived from a higher level requirement • i.e., L1  L2  L3  L4 • Described according to the PBS • Interface: • Those that one system imposes on another • i.e., RFQ requires a certain water flow • Described from system to system across the PBS

  9. Responsibility for authoring of requirements • Top-down: • Accelerator Integration Group (AIG) • i.e., the Lead Engineers • Interface: • The interfacing Work Packages • In the case of IK contributions, this means the contracted institution • Thus: • Top-down requirements will be authored in Lund • For delivery to CEA/CNRS for agreement • Interface requirements will be authored by CEA/CNRS and appropriate WP’s • For delivery to AIG in Lund
