Aims of Corolle


Problematics

January 2003: launch of Rosetta probe.

October 2012: landing on Wirtanen comet after
one year of close observation and mapping.


During the 9 years of cruise before science
operations: Lost of knowledge due to technical
and scientific entities dismantling.

Aims of Corolle


Solution

Settle a project technical memory process, to
insure a knowledge continuity from the
beginning of the development to the end of
the flight operations



SPACEOPS Oct 2002

KM objectives


Information signification is context dependent


Example: science, history , vocabulary


Need to keep formal and non formal
knowledge + know
-
how


Need to preserve, classify and organise
formal and non formal information


Missing information appears after
interpretation and exchange of the info. Need
to update the knowledge


SPACEOPS Oct 2002

KM needs


Need to:


collect


organise


validate


qualify


quantify



High quantity of information collected and
need of KM tool.


SPACEOPS Oct 2002

Corolle main objectives


Archive of information objects: document,
data, email, report, schematic, photo,
commentary


Easy user contribution by addition of
documentary object through convenient
email mechanism


Easy knowledge access through friendly
user interface: multilingual, qualifying
criteria, full text and/or reference based
search, efficient document restitution

Conclusion


Knowledge preservation is on process


Currently 3000 files (250 new files per
month)



Corolle system and management
process are operational


Corolle could be used for other project
including in Concurrent Engineering
Environment
