Can a Software Engineering Environment (SEE) be built from Open Software? We introduce the requirements for a SEE in a large-scale, global, distributed object-oriented software development project and suggest how open software solutions can fulfill these requirements. Our suggestions are being applied in the domain of network development within Nokia.95


Seven Software Engineers as One Mind

Lawrence Carleton
BAE SYSTEMS, Inc.
This is an analysis of the mental life a team of software engineers can have as a cognitive entity in itself, distinguishable from the engineers who participate in the team. Literature in cognitive science, philosophy, and software development is cited to support the analysis and provide examples.


Realizing Adaptive Systems

William Ray
Naval Postgraduate School
For a system to be truly adaptive, it must also change in support of evolving technologies and ontologies. When engineering to support these requirements, some of goals of reflective technologies can also be met without changes to middleware and languages. The Enterprise Intelligent Distributed Architecture (EIDA) is an attempt to realize these goals by creating a set of development tools that are also deployed with the system as run time servers. By completely automating the development of key components of the runtime system, the goal is to enable the adaptation of these components to changes in the environment, technology and ontology of the system.


GOOAL: Generating Object Oriented Models from Natural Language Analysis

Hector Perez-Gonzalez
University of Colorado at Colorado Springs
Jugal Kalita
University of Colorado at Colorado Springs
The purpose of this methodology is to promote rapid software development, reusability, and support memorable experiences in “object oriented thinking”. We automatically produce static and dynamic model views from natural language analysis of problems with the use of “Role posets” technique and a semi-natural language.


Domain-Specific Visual Languages

David Harel
The Weizmann Institute of Science
A powerful methodology for specifying scenario-based requirements of reactive systems is described, in which the behavior is “played in” directly from the system's GUI or some abstract version thereof, and can then be “played out”. The approach is supported and illustrated by a tool, which we call the play-engine.
