Ralph Johnson is a Research Associate Professor with the Department of Computer Science at the University of Illinois at urbana-Champaign. He is one of the four co-authors of "Design Patterns". He led the group that developed the first refactoring tool, the Smalltalk Refactoring Browser. He uncovered the Adaptive Object Model architectural style, has worked on frameworks of all kinds, and it currently working on refactoring tools for Fortran.

For the past few years, he has been working on the proposition that software development is about program transformation, transfroming version N of a system to version N, with N usually much larger than 1. Most programmers are working on software started by someone else. He has worked on the problem of updating applications when the libraries that they use change, on changing software to run on parallel processors, and on changing software to make it more secure. He thinks that nearly any architectural property can be thought of as a program transformation.

 
Kevlin Henney is an independent consultant and trainer based in Bristol, UK. He has variously developed and delivered training courses, consultancy and software across a number of domains ever since getting involved in professional software development in the late 1980s. Kevlin's work focuses on software architecture, patterns, development process and programming languages.

He has been a columnist for various magazines and online publications, including Better Software, The Register, Java Report and C++ Report. With Frank Buschmann and Doug Schmidt, he is coauthor of two volumes in the Pattern-Oriented Software Architecture series: A Pattern Language for Distributed Computing and On Patterns and Pattern Languages.

 
Nicolai Josuttis (www.josuttis.de) arbeitet seit vielen Jahren als unabhängiger technischer Projektleiter, Systemarchitekt und Berater in mittleren bis großen unternehmenskritischen IT- und SOA-Projekten. Unter seiner technischen Leitung wurden in den Bereichen Finanzwesen, Telekommunikation, Verkehrstechnik, Automobilbau und Maschinenbau mehrere mittlere bis große kommerzielle Softwaresysteme erfolgreich realisiert. Er ist Autor verschiedener weltweit publizierter Bücher zur praktischen Softwareentwicklung. Aufgrund seiner praktischen Erfahrung und Unabhängigkeit gilt er inzwischen als weltweit anerkannter Experte für die Umsetzung von SOA und verteilten Systemen. Sein Standardwerk "SOA in Practice" ist Anfang 2008 auch in deutsch unter dem Titel "SOA in der Praxis" beim dpunkt.verlag erschienen (siehe www.soa-in-der-praxis.de).

Her know-how in agile processes is based on over ten years experience in developing object-oriented applications. She has helped many teams and organizations all over the world to make the transition to an agile approach. She has a unique experience in applying agile processes within medium-sized to large mission-critical projects. This is also the topic of her book ‘Agile Software Development in the Large’.

Besides engineering software she has been designing and teaching OT courses in industry. Having completed a course of teacher training and led many 'train the trainer' programs in industry, she focuses also on techniques which help teach OT and is a main lead in the pedagogical patterns project. She has presented work in her main areas at ACCU (UK), JAOO (Denmark), OOPSLA (USA), SD West, SD Best Practices (both USA), XP (Europe) and Agile (USA).
