* Doing so in a way that still allows your entire app to appear to be a coherent whole is tricky.
To be clear, to have a talk that makes an impact there should be general lessons that can be extracted from the specific experiences you went through. The title of your talk should address the general lessons rather than the specifics.
Based on what you've shared so far it sounds like a potential title for your talk is 'Coordinating Modular Development'. Is that the general idea behind the talk you had in mind?
I do, however, understand and appreciate your point that the title of the talk should put the talk in a broader context, particularly addressing why the listener would be interested.
