This quantity provides a variety of the shows from the 1st annual convention on Analytical equipment in software program Engineering Economics held on the MITRE company in McLean, Virginia. The papers are consultant of the problems which are of curiosity to researchers within the economics of data structures and software program engineering economics. The Nineteen Nineties are offering software program economists with a very tricky set of demanding situations. as a result of funds concerns, the variety of huge new software program improvement efforts is declining. the first concentration has shifted to matters with regards to upgrading and migrating current structures. during this surroundings, productiveness bettering methodologies and instruments are of basic curiosity. The MITRE software program Engineering research convention was once designed to handle a few of th,~ new and tough demanding situations that face our career. the first aim of the convention used to be to deal with new theoretical and functions instructions in software program Engineering Economics, a comparatively new self-discipline that offers with the administration and keep watch over of all segments of the software program life-cycle. The self-discipline has got a lot visibility within the final twenty-five years as a result of dimension and value issues of many software program improvement and upkeep efforts, relatively within the Federal executive. We thank every person who helped make this convention a hit, in particular those that graciously allowed us to incorporate their paintings during this volume.

This resulted in a determination that there would be no tools commercially available within the next few years that would: (1) enable cost-effective expansion of the firm's current applications to support the demand for increased financial market trades processing in a 24-hour a day, global market; (2) create high functionality, multi-tiered cooperative processing applications that efficiently utilize the power and flexibility of -- * microcomputers and engineering workstations on the trading platform; 40 * fault-tolerant minicomputers for intraday trades processing and a link to the financial markets; * mainframe computers for current account and firm securities inventory management, and historical database queries to support trading analytics; and, (3) further control costs by paring down the overall level of developer expertise that needed to be brought together to create the firm's applications.

A number of research questions were on our and management's agenda when we began to examine software development using HPS at First Boston. These included: (1) To what extent did I-CASE support the software development process, leading to improved productivity and higher quality applications? (2) Did software reuse drive the results? (3) Are the gains recognizable in small-scale experimental project development? (4) If so, can they also be replicated in large-scale application development? This paper provides some insights to these questions by presenting the results of two phases of a multi-year field study that was carried out at the First Boston Corporation.

Figure 5 can be compared with Figure 2. A major difference between the two figures is that the Current Program in Figure 5 shows pronounced cost growth, while in Figure 2 the growth is just beginning in the later years. Only the Achievable Program is still able to reduce then-year spending on software. 3 Note: NPV reported in millions of 1992 dollars. Incremental NPVs may not be the difference between Current and Achievable NPV because of rounding. 2 ROI Sensitivity to Decreased Estimates of FT and FS This section shows the effects on ROI of significant decreases in the Ff and FS savings parameters in the model.
