Relevant Project Experience
IBM—CUSTOMER FACING
Program Manager, CICS/TS 4.1 Early Test Program
 Activities for CICS/TS 4.1 were similar to my activities for CICS/TS v3.2 (outlined below).
 Continued to grow program participation by seeking out and enrolling Education Providers and
Application Vendors with CICS-based products
 Created a Control Block “registry” for CICS which allows interested parties to request notification of
when specific CICS control blocks of interest are modified by the CICS Development Team
 Established a CICS “sandbox” z/OS system for education vendors who do not otherwise have
access to a running CICS system to build and execute sample applications for the purpose of
creating education materials.
 Expanded the program from 18 participating ISVs to over 40 participants.
Program Manager, CICS/TS 3.2 Early Test Program
 The development of CICS/TS 3.2 was well over 18 months using an “iterative” development
approach. Early code was provided in code drops approximately every four months.
 Responsible for planning, preparing, and presenting the technical education for changes introduced
with each code drop
 Developing the education required close coordination with the CICS development team
 Education was presented to CICS Beta Customers, internal IBM product development labs, and
ISVs targeting their respective products for “same day support” of the new release of CICS
Technical Lead— UNIX to z/OS Migration
 Technical Lead for an on-site IBM team to deliver a Proof-of-Concept for a major U.S. insurance
company
 Ported over 600,000 lines of Encina/DCE-based C++ code to CICS/TS running on z/OS
 Nineteen C++ libraries (DLLs) were ported to CICS/TS on z/OS with minimal changes to the source
o This had never been done anywhere before
 Coordinated the efforts of two mainframe programmers and two UNIX programmers
 Acted as “translator” of concepts between programmers in the two computing environments
 Defined the requirements and coordinated the conversion efforts of a vendor who supplied C++
base classes for Encina, but not on z/OS or CICS

EXTRACURRICULAR ACTIVITIES
CICS Architecture Forum Representative
 The CICS Architecture Forum (CAF) is a global group of customers, consultants, and ISVs who
work with IBM CICS strategists and planners to provide architectural solutions and direction to the
CICS family of products. It is the longest running customer council in the history of CICS and is
greatly respected by both the CICS and MQ development organizations
 I was one of five customers worldwide invited to the inaugural meeting in Hursley in 1994
 Co-authored technical papers on topics such as
o Cross-Platform Migrations
o Advanced Transaction Models
o Multiple COMMAREAs (which became the design for Channels and Containers),
o Structured Messaging (which became the design for WMQ Message Broker’s MRM)
o “N-pass” compliers for translators such as CICS and DB2 “EXEC” interfaces. That idea was
rejected, but it lead to the integrated CICS translator for the COBOL compiler
