He has held various technical leadership positions in MVS, OS/390, and z/OS product packaging and test. Mr. Miller worked closely with the first customer of Parallel Sysplex technology, playing a key role in the joint IBM-customer study and prototyping efforts. He has designed and implemented many large-scale system and integration test efforts for the zSeries platform and the z/OS software stack. Mr. Miller is a core member of the zSeries Business Leaders Council and also an original member of IBM's corporate-wide Software Test Community Leaders (STCL) group. Most recently, he has been working as the chief test architect for the z/OS Solution and Integration Test organization.

Richard Prewitt   IBM Server Group, 2455 South Road, Poughkeepsie, New York 12601-5400 (electronic mail: prewitt@us.ibm.com). Mr. Prewitt, a senior software engineer in the z/OS development laboratory, joined IBM in 1984 after graduating with a B.S. degree in computer science from Pennsylvania State University. He has worked in test over his entire career within IBM. He spent a number of years working as a function component tester on MVS/XA™, MVS/ESA™, and OS/390. His area of expertise includes base components of the operating system, Parallel Sysplex, and coupling technology. He spent a significant amount of time in designing and developing test-tool technology, and was one of the original creators and authors of the Component Test Tool (CTT), which is discussed in this paper. After leading in many of these areas, he took on a leadership role in the area of integrated testing. He was the overall leader for the OS/390 COMBAT (OS/390 Community Build and Test) team. This is a worldwide team of product packagers and testers who built and tested an integrated testing platform for each release of z/OS. Most recently, Mr. Prewitt has been working as the test project manager in the IBM License Manager area.
