Organization Plan D. Fierro THE LIFE CYCLE OF MODERN TECHNOLOGICAL PROJECTS

Roles and Responsibilities The PI, Project Investigator, has overall responsibility for the direction, execution, and completion of the project. He leads the Project ensuring that the scientific goals are achieved. The PM, Project Manager, have day to day responsibility for managing the project to achieve the goals within the approved schedule and budget. He develops the Project Program and supervices the Tender definition. The PE, Project Engineer, is responsible for overall engineering, logistics, production, integration and test tasks coordination and performance. The PE has the responsibility to establish the tech. spec, controls the common interfaces, defines the overall design and establishes procedures and plans D. Fierro THE LIFE CYCLE OF MODERN TECHNOLOGICAL PROJECTS

The Project Controller monitor the progress of work and will provide the PM with the status of the activities. They makes periodic updates of the scheduling baseline and propose corrective actions, if necessary, to prevent and reduce any slippage that could occur during the project life. The Project Scientist, define the scientific requirements and has the responsibility of ensuring that the scientific objectives, specifications and programmes are adequately met. The AIV manager is the responsible of the final Instrument integration and logistic activities and supervises the execution of the final tests. The Documentation Manager has the responsibility of the codification, archiving and distribution of the Documentation. The DM can be in charge of the Configuration Control with the objective to establish and maintain a systematic change management process. (CIDL) Critical Item Data List Roles and Responsibilities D.

Risk Areas Requirement phase. Programmatic risks are first reduced by assessing the system requirements. Excessive requirements are avoided. Development/production processes. Margin in performance may be included in the specification of subsystems. Where the performance of a subsystem can deviate from an ideal value a budget error will be calculated. Operational risks demand the following types of responses: avoidance of hazardous conditions (processes, materials, operational procedures), reduce the consequences of failure (e.g. by redundancy), management of degradation (by monitoring of condition). A Risk Register will be maintained following the PDR. Each risk source will have an “owner”, whose task it is to manage the risk D. Fierro THE LIFE CYCLE OF MODERN TECHNOLOGICAL PROJECTS
