Recent Projects

Software implementation for synchronization and protection switch features

• Insured that all issues were resolved by the software team by reviewing all issues, deferring less important issues, and adjusting systems requirements to meet schedules without sacrificing critical system features and performance. Used ClearCase and DOORS object-oriented database and bug-tracking tools to ensure system quality.

• Worked directly with software development and system test groups and management to understand testing issues and mediate conflicts among team members.

• Championed needed additions to product features for later releases, and guided software development team to obtain fast development of most important system capabilities.

• Resolved testing issues to free software team to concentrate on meeting delivery schedules.

Requirements development for broadband Sonet/SDH optical transmission and cross-connect system

• Developed high-level market-oriented system requirements for Sonet/SDH synchronization, protection switching, and interface features for Lucent's Wavestar product line of fiber optics multiplexers. Developed requirements for Sonet/SDH, ATM, frame relay, T3/DS3, T1/DS1 interfaces.

• Developed TL1 user interface commands and object-oriented data structures for user provisioning and retrieval of system status.

• Worked as part of team to align all system requirements, and insure orderly development of a sequence of planned releases. Resolved conflicts among system requirements documents by obtaining compromises without sacrificing important market needs and standards compliance.

• Developed requirements using FrameMaker, MS Word, UNIX, MS Windows software tools. Maintained documents using ClearCase change control. Managed information on web site using HTML, PDF, and FrameMaker files.

System definition for Sonet/SDH optical transmission system

• Co-author and co-leader of system definition document for major new Sonet/SDH optical networking & fiber optics multiplexer  product line.

• Alignment of customer needs, standards compliance, and product strategy with development constraints. Working with multiple teams to align differing interests towards a common goal. Solving issues to continue the progress of the project.

• Presentation of systems application for this system to senior management review team to obtain continuing support for the project.

Requirements development planning and leadership

• Encouraged and practiced an "early rough draft" strategy for document development rather than attempt for immediate perfection

• Encouraged and practiced emphasis on development of critical features for early product releases, while planning to complete the feature set in later releases.

• Wrote initial drafts of several areas of requirements which were then handed off to other engineers. Provided continuing support to other systems engineers and developers in these areas.

Product and market management support

• Supported development of customer documentation

• Supported developed of customer proposal responses.

• Wrote technical sections of product proposals for major customers.

Education

• Ph.D., Systems Engineering, University of Pennsylvania, Philadelphia, PA, 1980.

• M.S.E., Systems Engineering, University of Pennsylvania, Philadelphia, PA, 1977.

• A.B., Physics, Catholic University of America, 1975. Summa cum laude, Phi Beta Kappa, honors in physics.
