F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009 Contents KM3NeT logic layer structure Definition of a PBS Data needed for QA implementation Data needed for RA implementation F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

PBS What it is: A hierarchical breakdown of the products which depicts the entire system architecture. What it is not: A project schedule or a chronological listing An organizational hierarchy F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

Logic layer structure proposed Chinese box model in which boxes are also connected each other F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009 Each boxes constitute a layer in which components are connected in tree logic Storey 1 Detection Unit 1 SJB 1 Storey n Storey 1 Detection Unit n Storey n SJB n F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

Why do we need to do this: - To ensure all works needed are included - To be sure that every body have the same view of the project To serve as an efficient tool to converge to a consensus and becomes inputs to Define activities Estimate cost Plan risk management Plan resources F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

What it must be: What it must not be: Remark: A list of components associated to requirements with identified and testable performances or characteristics A sufficient (with no over killing) and necessary description of the complete system What it must not be: A list of processes or functions performed in the development of these products. Remark: This decomposition process MUST be iterative It cannot be a one shot effort F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

Define a PBS will be more than “useful” to organize the project Summarize Define a PBS will be more than “useful” to organize the project and it is an essential step in its development plan The list of deliverable products will also help to define The tasks to produce these components and the material And resources associated.

Data needed for the QA implementation (1/2) For each system/component Definition A description of the component/system Functions A definition of the functions to be performed by the component/system within the KM3NeT dector operation life F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

Data needed for the QA implementation (2/2) For each system/component Requirements A definition in measurable terms (including max, min and nominal values) of what must be done by the component/system to be acceptable to the function in the project: Physical requirements Power requirements Structural/mechanics requirements Enviromental requirements, i.e. undersea water depth, and other paramenter Success criteria A definition in measurable terms of what must be done for the component/system to be acceptable to the success of the project F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

Data needed for the RA implementation Layer by layer has to be given: how many and what components constitute that layer (including design/reports and every useful specification) design of the parts and number (including reports and every useful specification) design of the connection and connectors between them (and if is possible a sketch of the system like) the failure rate (if it was evaluated) and the way in which it was evaluated (test report, and FIT rate value related to each part) F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009

F. Louis, J. Giraud IRFU/SEDI Paris, 23-02-2009 Conclusions Using such a tool will be useful to: Have a global view of all proposals Make parallel analysis between “same” object Be sure that all components of the project will be take in account It is recommended to implement the PBS with WP7 representatives F.
