The last few days (cfr FIM 2010 R2 beta launch and FIM 2010 beta exam), I had the same discussion with several people, regarding the definition and use of the ‘triple’ terminology in FIM.
Well, you’ve got 2 of them when talking FIM.
One of them is the synchronization configuration triple, which covers the combination of:
- MPR (management policy rule)
- WF (workflow)
- SR (Synchronization rule
It’s discussed in detail over here: http://technet.microsoft.com/en-us/library/ee534902(WS.10).aspx
The following illustration in the Technet article shows the dependencies of the synchronization configuration triple components:
Another FIM situation where ‘triple’ is used, is (troubleshooting) outbound synchronization.
Take a look here: http://technet.microsoft.com/en-us/library/ff608273(WS.10).aspx (Introduction to User and Group management.).
“In FIM, a complete outbound synchronization object set is known as an outbound synchronization triple. The outbound synchronization triple relationship is managed by the FIM Service and applied by the FIM synchronization service.”
The outbound synchronization triple depicts the relation between 3 objects :
- object (like person, …)
- ERE (Expected Rule Entry)
- SR (sync rule)
The following illustration on Technet page shows the relationship between the three objects.

If you would like to dive in to it, here is the place to go: Understanding Data Synchronization with External Systems on the MS Technet website.
If you would like to know more about troubleshooting the triple, check this article on MS TechNet Wiki: Troubleshooting Generic FIM Synchronization Errors.
In addition to that, also take a look at Brad Turners’s blog post : FIM 2010 – New Appreciation for ERE/DRE.
