Simple Drupal Business Case
There are a huge number of features that make Drupal an obvious choice for enterprise development projects, but why would your business benefit from a Drupal website as opposed to any other type of site? Put simply, this boils down to the following three points:
1. Standing On The Shoulder of Giants
2. No Lock-In
A programming methodology may not seem like a business case argument, but actually Drupal's extensibility means that it is usually not necessary to rebuild a website when new features need to be added. The modularity and extensibility also facilitates the option of phases during development in order to break down cost into manageable portions.
