VISTA, a success story - from conceptual design to operation

摘要

This paper considers the development and progression of the VISTA telescope, from conception to the point where it is now being operated by the scientific community (end user). It analyses and evaluates the value of effective project management and systems engineering practices with practical examples. The practical application of systems engineering is addressed throughout the requirement capture and management, design, manufacture, assembly, and installation, integration, verification and acceptance phases, highlighting the value gained by appropriate application of step-by-step procedures and tools. The special emphasis given to the importance of effective systems engineering during on-site installation, verification and validation will be illustrated. Project management aspects are covered from tendering and procurement through contractor management processes to final integration and commissioning, with great emphasis placed on the importance of a "win-win" approach and the benefits of effective, constructive customer/contractor liaison. Consideration is given to the details and practicalities of day-to-day site management, safety, housekeeping, and the management and support of site personnel and services. Recommendations are made to improve the effectiveness of UK ATC system engineering and project management so that future projects can benefit from the lessons learned on VISTA.
