Better Testing... Better Results

Scott Barber

Chief Technologist, President and CEO

Professional Summary:

Scott Barber

Scott Barber is viewed by many as the world’s most prominent thought-leader in the area of software system performance testing and as a respected leader in the advancement of the understanding and practice of testing software systems in general. Scott earned his reputation by, among other things, contributing to three books (co-author, Performance Testing Guidance for Web Applications, Microsoft Press; 2007, contributing author Beautiful Testing, O’Reilly Media; 2009, contributing author How to Reduce the Cost of Testing, Taylor & Francis; TBP Summer, 2011), composing over 100 articles and papers, delivering keynote addresses on five continents, serving the testing community for four years as the Executive Director of the Association for Software Testing, and co-founding the Workshop on Performance and Reliability.

Today, Scott is applying and enhancing his thoughts on delivering world-class system performance in complex business and technical environments with a variety of clients and is actively building the foundation for his next project: driving the integration of testing commercial software systems with the core objectives of the businesses funding that testing.

When he’s not “being a geek”, as he says, Scott enjoys spending time with his partner Dawn, and his sons Nicholas and Taylor at home in central Florida and in other interesting places that his accumulated frequent flier miles enable them to explore.

  • “Scott Barber is one of the very few real experts and practitioners in performance testing and analysis.  He combines experience and passion for the problems of performance with a very scientific approach that takes into account complex, but critical, performance affecting variables that are conveniently ignored by most practitioners (making their performance results about as reliable as horoscopes).  Scott’s body of work, publications, and presentations clearly demonstrate that he has done his homework, knows his stuff, and his results are going to give you uniquely clear and realistic insights and solutions for your performance needs.” Alberto Savoia, Founder and CTO of Agitar (Former Executive of Google)
