It gives you that ability, true, but you still have to do it right.  The 
mere presence of binder source alone does not provide this.

First, to get it out of the way, we are talking about re-binding here, not 
re-compiling.  I presume Implementer would just be re-binding the *PGM and 
*SRVPGM objects that are bound to your service programs.  I point this out 
only because binding is not that expensive in terms of time, at least 
compared to compiling.

I can't speak for Implementer, but in TurnOver the X-Ref process is not 
exactly behind the scenes.  In TurnOver you create a promotion request, 
called a form, and TurnOver can optionally run an X-Ref process to add the 
objects to be re-compiled or re-bound.  You can run this process 
interactively and choose which objects to include, or you can edit the 
form after the fact and remove items you do not want.  If you were only 
promoting this service program and did not want to rebind anything, you 
would just take the option to not run the X-Ref process.

I do not agree.  There is a lot of value in binder source.  For one thing, 
you may want certain procedures to be private and others to be public. The 
fact that your change management solution is being safe and rebuilding 
everything for you should not stop you from using binder source.
