Continuous Testing through Service Virtualization
- 2. Allan Wagner IBM IBM-certified IT Specialist Allan (Al) Wagner is currently a technical manager and evangelist with IBM, driving thought leadership, strategic initiatives, and tangible solutions with a specific focus on quality management, test automation, and service virtualization. In his fifteen years of practical IT field experience, Al has assisted, supported, mentored, and enabled teams with their IT application infrastructure, development, implementation, and operations challenges. A frequent conference speaker on software quality principles and techniques, Al also has authored or coauthored the IBM Service Virtualization for Dummies book and numerous papers on quality management and test automation.

Today • Organizations are asking teams to release higher quality software sooner. • Development teams are becoming more and more agile; testing still never seems to have enough time. • Software quality continues to suffer.
