ADDE's objectives are:
- to develop guidance for the design of distributed application systems, driven by the business requirements of distributed enterprises.
- To address coherent designs that use network-based technologies such as groupware and Inter/intranet as well as database transaction processing, in anticipation that the technologies will converge over the next few years.
- To demonstrate how the general approach can be used to extend IS development methodologies. It will use UML (being developed by Booch, Jacobson and Rumbaugh) for its primary demonstration, but also take account of established IS methodologies such as BOS-Engineering, MERISE, Q-MEIN, SEtec and SSADM.
- To construct a repository for the specification and design products needed for distributed systems, capable of supporting multiple IS development methodologies via interfaces to CASE tools.
- To validate the approach and the tools on projects in the European Community, Switzerland and the USA (including projects that span more than one country), using a range of IS development methodologies.
Business pressures and technology advances are encouraging organisations to develop enterprise-wide and inter-organisation distributed systems. Without a sound approach to distributed system design, applications will not be robust and will not be able to accommodate change. Without a common approach, integration of systems from different vendors and different organisations will be expensive and slow.
Creating de jure standards could take many years. A better solution, proposed as "Application Development for the Distributed Enterprise" (ADDE), is to bring together, in one consortium, representatives of leading methodologies, suppliers and user organisations, to build on previous practical work and to apply the results as they emerge.
ADDE will develop guidance and tools for design of IT-based systems that provide information to support business activity, and that may automate parts of that business activity.
ADDE will deliver three products:
- A metamodel of components of project deliverables, in FIVE parts: business process, business data, computer system data and function, work practice, computer system architecture. The first two parts have already been published in 1994 as EML, in the ASSET project under ESPRIT. The metamodel and example deliverables will use UML notations.
- A guide on how to develop systems for supporting distributed business, where business requirements are the drivers. A major focus will be on providing design principles and guidance on more effective use of tools (most of the guidance that currently comes with tools is about how to use them, not how to design systems).
- A demonstration repository as a functional, but not necessarily user friendly, implementation of the metamodel and supporting tools used in system development. Softlab will develop the repository using its OMS technology.
The ADDE guidance, metamodel and tools interfaces will be available from early 1997.
Collaboration with real projects will be an integral part of ADDE. Concepts, guidance and tools will be applied to several real projects focusing on different aspects of ADDE, including business process modelling, distributed work practice and workflow management, integration of groupware and database, migration of legacy as well as distributed database design. The majority of this collaboration will be in parallel with ADDE development, providing feedback from the real world, and reflected in ADDE's deliverables.
