14. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background The audit criteria: DRC for "David Ross Criteria". David is a retired quality engineer He started Cacert's Audit He was called to Grand Jury duty

15. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background DRC has a strong feature: requires the ➔ Risks, ➔ Liabilities, and ➔ Obligations to be clearly stated to everyone!

16. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background This raised several huge barriers for the CA: what exactly are the R/L/O? who do they apply to? are they reasonable? and, how do we deal with them?

17. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background These barriers are subtle: ➔ DRC doesn't ask them to be fair, but ➔ disclosure of R/L/O makes us consider them but CAcert people want them to be fair. which means we have to deal with them!

18. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background One big result of this thinking process we required: ➔ a CAcert Community Agreement ● and it had to do following things:

19. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background a. make Members a mutually binding Community. b. to state the R/L/O c. to limit the liabilities ➔ 1000 Euros ➔ to *allocate the liabilities* back to the Members

20. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background How do we allocate the liabilities? ➔ By making our own „forum of dispute resolution“, ➔ agreeing to be bound to that resolution, ➔ writing a Policy to control that process: ==> Arbitration.

21. www.cacert.orgwww.cacert.org © CAcert, 2009 Ulrich Schroeter, Assurer Training Events, April 2009 Audit Background Summary: The original “Why” of Arbitration: ➔ Audit (DRC) forced disclosure of Liabilities ➔ simple fix: limiting ➔ complex fix: allocation ➔ the safe and cheap way to allocate is: ➔ to use our own Arbitration (Last section discusses „How“.)
