2 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator 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: 1.Backward 2.Forward That means: 1.A project lifecycle phase can be concluded because all belonging outputs are generated 2.The subsequent lifecycle phase can be started because all necessary inputs are available

5 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator 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

6 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator 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 Reviews Contents –> 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

7 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Deliverables / System Description The Deliverables / Systems Description shall clarify: 1.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 2.Scope What shall the system achieve and what not anymore (Abgrenzung) Which performance extent is needed, which not anymore 3.Concept & Layout How shall the system achieve it General layout (segmentation, subcomponents, hardware, software, assembly steps)

8 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Requirements Analysis Requirements Elicitation Problem: Beside formulated requirements there are usually non-formulated expectations – They might be as important! Requirements Analysis shall ensure: 1.Completeness (product lifecycle, interfaces at each lifecycle phase) 2.Consistency (eliminated contradictions = negotiation results) 3.Prioritisation (must, nice to have, must not) 4.Verifiability (req. must be formulated such that their fulfilment can be verified / measured

9 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Target Specifications Target Specifications shall define: 1.Set of Requirements that shall be satisfied finally (issuers) Functional req. (= capabilities) Non-functional req. (= constraints; incl. regulations, standards & norms) 2.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) 3.Explanation how that technical layout will satisfy the requirements

10 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Design conceptual –> detailed The Design shall comprise: (conceptual –> detailed; high level –> low level; feasibility study –> shop drawings) 1.System Model ("Architecture": 3D, UML, written documents …) 2.Calculations (analytical, numerical) 3.Simulations (FEM, Start-to-End, Monte Carlo …) 4.Safety analysis (written documents, prototype tests …) 5.Interface Definitions (e.g. 3D Placeholders -> confirmed ‘Collision Free’, documents approved by requesting & interfacing parties like WPLs, Coordinations … )

11 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Fabrication Planning Fabrication Planning shall comprise: 1.Envisaged methods (description and reasoning, incl. advantages, constraints, disadvantages) 2.Fabrication adaptation (adapted models, drawings, plans …) 3.Side Conditions (availability/readiness of subsequent issues, e.g. test or storage environments, trained personnel …)

12 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator QMP Concluding a lifecycle phase requires two QM measures: 1.Verification (= Requirements coverage check; "Is the right thing done?") 2.Validation (= Compliance check; "Was it done right?") The Quality Management Plan* shall stipulate all QM measures for all product lifecycle phases The QMP shall therefore pre-define (pre-identify) all: 1.Verification criteria, methods, tools 2.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

13 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Tendering Documents Tendering Documents shall comprise: 1.Technical part (written specs, fabrication models, shop drawings, QM measures …) 2.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

14 Thomas HottTechnical Reviews Contents, 2 nd CDE-WS, 12 th & 13 th May 09 XFEL Technical Coordinator Further Technical Documents Further Mandatory Technical Documents are: 1.Instructions / Manuals (assembly, installation, maintenance …) 2.Drawings (circuit diagrams, operation flow charts …) 3.Safety & Health Plans (for installation/integration activities at XFEL conducted under the own WP responsibility) 4.… (to be defined for each WP)
