Elimination of processes
which doesn’t create value
to customers

Open System Engineering
Environment
“A tightly integrated environment to OSEE
support lean engineering principles
across a product‘s full life-cycle in
the context of an overall systems
engineering approach“ - Boeing

OSEE
But why?
Eclipse already does a wonderful job in integrating
applications at the UI level
OSEE goes a step further by integrating applications at
the data level
Also provides out-of-the-box solutions to manage this
data

ATS - Just another change tracking
system?
Tightly integrated and highly flexible
change tracking system
Uses the same data model provided
by OSEE Application Framework
Powerful workflow engine to create
new workflows

To OSEE or not?
End to end traceability not yet available
Strong platform dependency for some components
Many components could be replaced with existing Eclipse
technologies
Inactive newsgroup, disintegrated documentation, not up-
to-date release plans
17

To OSEE or not?
Avionics project uses OSEE with
300+ users
10,000+ requirements
125,000+ artifacts
500 branches
Scalable architecture with load balancing
Easily extensible data model combined with persistence and
versioning
18

Conclusion
OSEE has great potential to be used
as an open source engineering
platform
OSEE is in a promising state for an
Incubation project
The committers of the project needs
to publish reliable release plans
The tool could be greatly improved
with more community interest, tool
adoption and contribution
