Future Trends, Implications in Cost Estimation Models
نویسندگان
چکیده
The rapid pace of change in software technology requires everybody in the software business to continually rethink and update their practices just to stay relevant and effective. This article discusses this challenge first with respect to the USC COCOMO II software cost modeling project, and then for softwareintensive organizations in general. It then presents a series of adaptive feedback loops by which organizations can use COCOMO II-type models to help cope with the challenges of change.

متن کاملUncertainty Analysis in the Evaluation of Extreme Rainfall Trends and Its Implications on Urban Drainage System Design
Future projections provided by climate models suggest that the occurrence of extreme rainfall events will increase and this is evidence that the climate is changing. Because the design of urban drainage systems is based on the statistical analysis of past events, variations in the intensity and frequency of extreme rainfall represent a critical issue for the estimation of rainfall. For t...
