Abstract. The Systems Engineering Development Program (SEED) was initiated to help Goddard resolve a Systems Engineering skill shortage. The chronology of events and the experiences of the pilot program are outlined to describe the development of the present program. The program goals are included in order to give a focus on what the developers saw as the program drivers. Lessons learned from a pilot program were incorporated into the present program. This program is constantly learning from its past efforts and looks for continuous improvement. We list several future ideas for improvement and change.

An au tomatic photoelectric instrument and method for t he continuous meas urement of t he ozone in the earth's atmosphere at low altitudes are described. The method is physical rather t han chemical in character and is based upon t he optical absorption characteristics of ozone in the Hartley and Huggins ul t raviolet bands. Th e ins trument makes use of a lowpressure mercury are, which is situated at a di stance of 1,450 feet from the reco rding s tation t hat emp loys a 1P28 photo mult iplier as a d etector . The lig ht beam is modulated, at 510 cycles per se cond, so that the output of t he photomultiplier is fed into a t uned alternatingcurrent ampllfier and amphfied to the recorder level. By means of a Geneva m ec han is m which changes t he glass filters, the radiant energy from t he lamp is separated into band~ primarily at wavelengths 253 .7, 365.5, a nd 405 .0 millimi cro ns. From the ratios of the de1kctions for t he different spectral regions it is possible to d etermine ozone concentration in t he range from a few te nths of 1 part to many p ar ts per 100 million.

Implementing capabilities on the World Wide Web should never be taken lightly. A good systems engineer is able to examine such implementations from all points of view, including political, legal, security, access, technical deployment, and quality. The evaluation discussed in this paper was conducted to ensure that the National Aeronautics and Space Administration (NASA) was proceeding in a correct direction by implementing RECALL a Lessons Learned System on the Web and, subsequently, did so successfully. The systems approach extended well beyond technical implementation to several issues that are not often addressed by an implementation team. The resulting evaluation increased the team's sensitivity to such issues and, in fact, the authors believe that the evaluation provided as much benefit as the system itself.

NBS Technical Notes are designed to supplement the Bureau's regular publications program. They provide a means for making available scientific data that are of transient or limited interest. Technical Notes may be listed or referred to in the open literature.

A multicontractor/government systems engineering team analyzed a government organization in order to develop recommendations to re‐engineer its activities and improve its processes in terms of both efficiency and quality. The organization was NASA/Goddard's Mission Operations and Data Systems Directorate (MO&DSD), which 24 hours/day, 7 days/week supplies services including data capture, data processing, operations, and communications between orbiting spacecraft and ground based investigating teams. The service operations and the underlying organizational processes were analyzed using a systems engineering approach assisted by tools consisting of a Total Quality (process) Model (TQM) instituted by AlliedSignal Corp. and the Viable Systems Model (VSM) which has its genesis in management cybernetics. Aspects of both the TQM and VSM are discussed and compared along with their application in analyzing the processes of MO&DSD. Both analyses resulted in numerous recommendations to improve MO&DSD's activities including administrative, personnel, and operational procedures. The similarities and differences in the recommendations are compared along with a discussion of the use of these two analytical techniques.
