Context and Motivation
Pg. 4Proprietary and Confidential ESA-EUSC 2005, ESRIN, Frascati, October 5-7, 2005
Since each task involves, in general, many experts, each of whom possesses specific knowledge and skills to perform a part of the whole job, and many tasks may be simultaneously on-going within the Centre, there naturally arises the problem of coordinating and optimising the whole process.
Moreover, the envisaged solution should also enable future evolutions in the Centre role and in the kind of services provided to users.
Context and Motivation (Cont.)
Pg. 5Proprietary and Confidential ESA-EUSC 2005, ESRIN, Frascati, October 5-7, 2005
Objectives:
Identifying actual needs of all EUSC actors (i.e. participants to the main process).
Integrating different data views through a Common Information Model.
Automating routine steps of activities via application software.
Providing practical support to concurrent, human-driven activities, through an easy-to-use, custom-developed, cooperative environment.
Providing preliminary reporting capabilities to measure the productivity of the overall application infrastructure.
