Applying RUP an Enterprise Level

� Enterprise architecting

�Defining an architecture that underpins a number of systems

� Strategic reuse

�Developing reusable assets that are used within a number of systems

� Systems engineering

�Developing a system that contains elements of hardware, software, workers and data

� Enterprise Application Integration

�Developing a solution that includes the integration of a number of legacy systems

� Packaged application development

�Developing a solution that includes the configuration of a packaged application, such as an

ERP or CRM solution

� Outsourced development

�Defining an architecture that lends itself to the outsourced development of its constituent

parts, whilst ensuring the quality and integrity of these parts

� And … SOA!

Reusable Asset Specification (RAS)

� Reusable Asset Specification (RAS)

�Describes the structure and nature of assets

� Each asset is described in terms of

– Classification

– Solution

– Usage

– Related Assets

�The packaging of assets

�An interface to a RAS Repository Service
