Software Reuse

Dr. Ivar Jacobson, Vice President of Business Engineering, is the inventor of the OOSE method, and he is also the founder of Objectory AB in Sweden, which recently merged with Rational Software Corporation. Dr. Jacobson is the principal author of two influential and best-selling books Object-Oriented Software Engineering--A Use Case Driven Approach (Computer Language Productivity award winner in 1992) and The Object Advantage--Business Process Reengineering with Object Technology. He has also authored several widely referenced papers on object technology. One of the most famous papers is his first OOPSLA '87 paper entitled "Object-Oriented Development in an Industrial Environment," which presented the first truly object-oriented method ever published. Ivar Jacobson's use-case driven approachhas had a very strong impact on the entireOOAD industry, and he himself has become one of its "icons." Consequently, he isa frequently invited keynote speaker and panelist, debating OOAD topics withcolleagues and methodologists such as Grady Booch, Jim Rumbaugh, StevenMellor, and Rebecca Wirfs-Brock at major OO conferences around the world. He is well known for his pioneering work and more than 20 years of experience inusing object methods for the design of large real-time systems. His earlyobject-based design technique has evolved into the international standardITU(formerly CCITT)/SDL. Dr. Jacobson also regularly serves on the OOPSLA, ECOOP, and TOOLSprogram committees, and he is a member of the advisory board of the Journal ofObject-Oriented Programming. In 1994, Ivar Jacobson received the first Swedish Computer Association (SCA)award (the Kjell Hultman prize) for "extraordinary achievement in promotingefficiency and productivity in the development and use of informationtechnology." Martin Griss is a Senior Laboratory Scientist at Hewlett Packard Laboratories where, as HP's "Reuse Rabbi", he created the Corporate Reuse Program and led HP's technical contributions as co-submittor of UML to the OMG. He also writes a reuse column for Object Magazine and is active on several reuse program and steering commitees. Patrik Jonsson works at Rational Software Corporation in Sweden as a Senior Consultant where he has been developing the architecture and method of the Objectory process with a current focus on reuse and user interface development. 0201924765AB04062001
