2.15.1 Why use Reusable Parts?

Reusable parts allow you to define components that can be reused in many different applications. The ability to quickly and easily reuse existing parts will yield significant benefits in the areas of:

• Productivity – You don't have to reinvent the wheel. You can reuse logic that already exists and that has been tested.

• Quality – Since reusable parts have been used before, they are much more likely to function first time than any new code that you have to write.  

• Consistency – Since many reusable parts have a visual aspect, reusing them will create a more consistent look and feel in your applications.

• Maintainability – If you change (or correct) a reusable part it is instantly changed in all the applications that use it.
