Managing your Applications vs Hierarchical Model View Controller(HMVC) pattern

I'm afraid you're probably going to have to be more specific on what you mean by "Managing your Applications".

There are some minor differences between HMVC implementations, but the basic idea of HMVC is that you can structure your application as a series of modules, each containing their own MVC triads. In most implementations, there is also some method available for executing a method from a controller outside of the current MVC triad (usually a controller can load another controller and execute the other controller's methods). As with most variations of MVC (and MVC itself), there probably isn't one set-in-stone answer to what HMVC is and how it should be used, though, or even a strong definition of how it differs from many of the other variants.
