Enterprise Resource Planning (ERP) systems exemplify a particular form of application architecture reuse. Which of the following best describes this form of reuse?

A generic system is configured and adapted to create a specific business application, allowing application reuse without re-implementation

ERP systems reuse the user interface only, with all business logic re-implemented for each organisation

ERP systems are custom-built from scratch for each organisation and share no common code

ERP systems reuse individual software components but always require a completely new architecture

Correct Answer

A generic system is configured and adapted to create a specific business application, allowing application reuse without re-implementation

Explanation

ERP systems from companies such as SAP and Oracle, and vertical software packages (COTS) for specialised business areas, exemplify application reuse without re-implementation. A generic system is configured and adapted to create a specific business application - for example, a supply chain management system can be adapted for different types of suppliers, goods, and contractual arrangements.
