10. A note regarding the risks of using OSS
A common misconception regarding the risks
of using OSS is that there is a lack of
appropriate support services
We have commercial support contracts in place
for every OSS product we use
(RedHat/JBoss, Intalio, Alfresco)
The support we receive for the OSS products is
not inferior to the respective support we
receive for our commercial products
