Business applications play a crucial role for the day-to-day running of a business. These applications typically support a wide range of standard business processes like opportunity-to-order and order-to-cash. Customers using these solutions often demand extensions that will complement the existing functionalities offered by the standard application. The requirements for extensibility can be different for each customer which makes the enablement of business software for extensibility very challenging. In this paper we demonstrate some of these challenges and requirements through an example application and evaluate them against some state-of-the-art works on extensibility.
