====Foreword====
 
Analyses in Xfmea and RCM++ are now reusable object references. More specifically, the following analyses can be cast as objects:
 
*FMEAs
*Risk Discovery
*...
 
====Linked FMEA Illustration====
 
To illustrate the concept/application, consider the two systems, Widget and Fidget, along with their corresponding system hierarchies, as shown below (using metasyntactic variables for names).<br>

'''Widget'''
 
*Waldo
**''Wibble''  {{Font|[Wibble '''FMEA''']|9|tahoma|italic|rgb(128,35,205)}} 
**''Lidget''  {{Font|[Lidget '''FMEA''']|9|tahoma|italic|rgb(128,35,205)}} 
*Foobar
**''Foo''      {{Font|[Foo '''FMEA''']|9|tahoma|italic|rgb(128,35,205)}} 
**''Bar''      {{Font|[Bar '''FMEA''']|9|tahoma|italic|red}} 
 
| width="50%" |
'''Fidget'''
 
*Garply
**''Flob''  {{Font|[Flob '''FMEA''']|9|tahoma|italic|rgb(128,35,205)}} 
**''Baz''  {{Font|[Baz '''FMEA''']|9|tahoma|italic|rgb(128,35,205)}} 
*Fubar
**''Fu''  {{Font|[Fu '''FMEA''']|9|tahoma|italic|rgb(128,35,205)}} 
**''Bar''  {{Font|[Bar '''FMEA''']|9|tahoma|italic|gray}} 
 
|}
 
Then:
*The Widget is made up by the Waldo and Foobar subsystems and  their associated lower level items as shown. 
**Furthermore, assume that an FMEA analysis was done at the lower level items. 
*The Fidget system is made up of the Garply and Fubar subsystems. 
**Note that in this case both FooBar and Fubar subsystems share a common lower level item, Bar.
 
Since both, the Widget|Foobar|Bar (oBar)and the Fidget|Fubar|Bar (uBar) are the same item, one could (assuming no other stress/operational/interface/... differences!) use the same FMEA for both.
 
In this case they can be linked. This is done by linking the additional (linked items) to a source.  Linked items are identical and always in sync (i.e. changes made to one are automatically reflected in the other).
 
====Rules & Logic ====
 
When linking FMEAs or other analysis items: 
# A source needs to be defined.
##In this case if I am linking uBar to the existing oBar, oBar becomes the source and uBar is the link.
# Changes/Edits can only be made to the source (to streamline workflow and maintain project security levels).
#Sources can be any analyses in the same project, or any analyses in a Template project.
#Template level permissions and security applies, and similar rules exist as with any other resource in Synthesis.
## If user A has edit rights in project P1 but read only rights in Template T1, user A can link to the FMEA in T1 but cannot edit the FMEA, as edits are done at the source (T1) and A does not have edit permissions for T1.

=====Source Project Properties Overrides Link Project Properties=====
 
When using linked Xfmea resources the source project properties are used in the linked project.  In other words, if in the previous example the project containing Widget was using a 5 point occurrence scale (for the RPNs) and the project containing Fidget was set up with a 10 point occurrence scale the uBar FMEA would still be done using the 5 point scale of the source project.  The rest of the FMEAs in the Fidget would be done using the project scale (10 point).
