2. 3C • Technical Reviews shall ensure for all deliverables: • Completeness • Compatibility • Compliance • Generating deliverables is a long(er)-term process. • –> In order to ensure final 3C it is recommendable to subdivide this process into so-called Product Lifecycle Phases and perform intermediate 3C checks when moving from one phase to the subsequent. This has two aspects: • Backward • Forward • That means: • A project lifecycle phase can be concluded because all belonging outputs are generated • The subsequent lifecycle phase can be started because all necessary inputs are available Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

5. Reviews -> To be scheduled as milestones Reviewing is a QA measure of eminent importance Different Reviews are required at different times They couple WP activities and Central Tasks by sets of mandatory inputs & outputs They provide sureness to the WPs & PM They initiate ‘Follow-Up Activities’ in the project Concerns all major deliverables and sub-systems Timing must leave time for corrective actions Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

6. Reviews Contents • Mandatory Outputs / Inputs (Deliverables) • Deliverables / System Description • Requirements Analysis • Target Specifications • Design (conceptual –> detailed) • Fabrication Planning • Quality Management Plan (QMP) • Tendering Documents • Further Mandatory Technical Documents –> To be reviewed by all requesting & interfacing parties (WPLs, Coordinations) –> Changes to be incorporated (coordinated updating of all concerned docs) –> Finally to be approved by the Project Board Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

7. Deliverables / System Description • The Deliverables / Systems Description shall clarify: • Purpose • What shall the system effect (Zweck –> Was soll das System leisten) • General technical context • Which needs of other systems shall be satisfied • Which functionalities shall be delivered, provided to other systems • What do they mean for the performance of the • Scope • What shall the system achieve and what not anymore (Abgrenzung) • Which performance extent is needed, which not anymore • Concept & Layout • How shall the system achieve it • General layout (segmentation, subcomponents, hardware, software, assembly steps) Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

8. Requirements Analysis Requirements Elicitation Problem: Beside formulated requirements there are usually non-formulated expectations – They might be as important! Requirements Analysis shall ensure: Completeness (product lifecycle, interfaces at each lifecycle phase) Consistency (eliminated contradictions = negotiation results) Prioritisation (must, nice to have, must not) Verifiability (req. must be formulated such that their fulfilment can be verified / measured Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

9. Target Specifications • Target Specifications shall define: • Set of Requirements that shall be satisfied finally (issuers) • Functional req. (= capabilities) • Non-functional req. (= constraints; incl. regulations, standards & norms) • Exact technical specification how the deliverable shall be built • Design choices (e.g. technologies, materials …) • Self-produced parts • Purchase parts • Software (features & structure) • Interfaces (mechanics, signal levels & structure) Explanation how that technical layout will satisfy the requirements Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

10. Design conceptual –> detailed The Design shall comprise: (conceptual –> detailed; high level –> low level; feasibility study –> shop drawings) System Model ("Architecture": 3D, UML, written documents …) Calculations (analytical, numerical) Simulations (FEM, Start-to-End, Monte Carlo …) Safety analysis (written documents, prototype tests …) Interface Definitions (e.g. 3D Placeholders -> confirmed ‘Collision Free’, documents approved by requesting & interfacing parties like WPLs, Coordinations …) Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

11. Fabrication Planning Fabrication Planning shall comprise: Envisaged methods (description and reasoning, incl. advantages, constraints, disadvantages) Fabrication adaptation (adapted models, drawings, plans …) Side Conditions (availability/readiness of subsequent issues, e.g. test or storage environments, trained personnel …) Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

12. QMP The Quality Management Plan* shall stipulate all QM measures for all product lifecycle phases • Concluding a lifecycle phase requires two QM measures: • Verification (= Requirements coverage check; "Is the right thing done?") • Validation (= Compliance check; "Was it done right?") • The QMP shall therefore pre-define (pre-identify) all: • Verification criteria, methods, tools • Regulations, standards, norms Finally the QMP shall provide for each phase a complete specification of all needed inputs and resources, as well as planned outputs –> However, it will be a living document as understanding grows –> Nevertheless, it must be appropriate at any time * The QMP shall follow in general the recommendations of the EN ISO 9001 standard as much as possible Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

13. Tendering Documents • Tendering Documents shall comprise: • Technical part (written specs, fabrication models, shop drawings, QM measures …) • Commercial part (terms of contract, awarding matrix …) • –> Both must be complete, consistent, compliant (3C) • –> Criteria etc. to be pre-defined and are part of the QMP Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator

14. Further Technical Documents Further Mandatory Technical Documents are: Instructions / Manuals (assembly, installation, maintenance …) Drawings (circuit diagrams, operation flow charts …) Safety & Health Plans (for installation/integration activities at XFEL conducted under the own WP responsibility) … (to be defined for each WP) Thomas Hott Technical Reviews Contents, 2nd CDE-WS, 12th & 13th May 09 XFEL Technical Coordinator
