About the Authors

Combined, Lee and Celso have been working in the software industry for close to 30 years. During that time they have worked in development, services, and enablement organizations. Along the way they have used patterns in their projects and resulting solutions.

More recently, they’ve been building out PBE within IBM. During this time they have delivered enablement sessions, built courses, delivered conference presentations and workshops, written articles and Redbooks, participated in pattern-related studies, supported governance efforts, and contributed to IBM software products. In these efforts they have created patterns, used patterns, and helped others to use and build patterns.

Most of their PBE efforts have involved the use of IBM products such as IBM Rational Software Architect, Rational Application Developer, Rational Method Composer, and Rational Asset Manager. Because patterns are based on experience, the examples discussed use IBM Rational tools. However, the majority of the concepts, ideas, and guidance presented are applicable to tools provided by multiple vendors and the open-source community. Appendix B and Appendix C relate PBE to other approaches and provide tooling options.
