In my time at programming I created or used any number of routines over and over again that did a specific job, from just a small function like adding a number of days to a date to writing out an error report or selecting data from an SQL database.

Now I'm a business analyst and there are many process modelling applications out there that follow a set standard (BPMN for example). I know there's more than one way to skin a cat, programming has taught me that, so what I'd like to know is why can't I find a library of process model routines that I can import into the BPMN application of choice and build up a simple library of my own to create processes faster?
