[GRAAP-WG] Penalties

[Omer F. Rana]

  Dear Philipp,

Thanks for initiating this thread. There was some interest in this area 
some time ago, I also
asked the same question that you are asking in the context of the SORMA 
project. Did not
get a lot of replies.

In the work that Kassidy is identified -- we were primarily interested 
in a financial debit in case
of non-conformance to pre-agreed SLA terms. However, I believe there 
could be a number of
other options -- such as re-planning/re-scheduling or supporting 
capacity planning whereby
the penalty is used as a means to support future resource provisioning.

I guess two issues that were still not clear to me here were: (i) who 
does the penalty enforcement;
(ii) who does the monitoring (i.e. some kind of "trusted" monitoring is 
assumed often).

regards
Omer

Another option we are looking at is integrating a reputation system that builds profiles of each participant in the system based on the number of successful or violated agreements. These are very interesting options, but we have not yet fully developed them.
