SUCCEEDING WITH OBJECTS: REUSE IN REALITY
**********************************************

Ivar Jacobson discussed the reuse lessons learned nearly 30 
years ago by Ericsson, a Swedish telecommunications company, 
in an article in July's Object Magazine. When developing a 
new generation of software-based switching systems in the 
late 1960's, Ericsson achieved a high degree of reuse by 
designing the system architecture, the development 
processes, and the organization in harmony. "All three 
supported reuse as the natural way of working," said 
Jacobson. 

Jacobson claims architecture as the "key to success" and 
describes its use by Ericsson in detail in the article. He 
also relates the problems encountered by Ericsson and 
states, "All these combined experiences tell us that reuse 
does not happen by itself! Rather, achieving reuse is 
difficult. The only way we have observed that it is 
repeatable, manageable, and predictable is a systematic 
approach that reengineers everything about how you develop 
systems, with the explicit goal being to achieve reuse!"

Jacobson also discussed his continuing work (first at 
Objectory and now at Rational) on developing a configurable 
process for reuse. It will constitute the starting point for 
an organization to reengineer itself by means of system 
architecture, development processes, and organization to 
achieve reuse. "The technology is based on our use-case 
driven, OO-based approaches for business and systems 
engineering. We have named it Reuse Driven Software 
Engineering Businesses (RSEB)," Jacobson states. RSEB is 
based on three harmonized cornerstones: Architecture, 
Process, and Organization, which Jacobson describes in 
detail.
