A common issue that comes up when you plan to or have used a realist approach (i.e. realist review or realist evaluation) is the need to justify your choice of approach(es). This may happen, for example, in your thesis write-up or when making the case in a grant/funding application. Or you may need to convince colleagues that to address a research question, realist review and/or realist evaluation might provide more useful knowledge.
I am sure you all have your 'favourite' resources that you cite and/or refer others to, to make the case. For example, any of the seminal texts from Pawson and Tilley. But sometimes resources that make the case with in as short a space as possible can be helpful - especially if you are going to ask someone to read it :-)
A good starting point for open access resource will be the RAMESES Project website (www.ramesesproject.org).
Apologies in advance for the shameless plugging, but below are two sources you might want to share with others whom you have to convince about your choice of using realist review and/or realist evaluation (both are open access):

Do please add to this thread the resources you have used to help others understand why using a realist review and/or realist evaluation approach was the rational choice :-D
