Software estimates are an important input to project selection, planning, monitoring as well assessment of projects' success. However, the practice of estimation is also a challenging activity for many practitioners, and there is a continuing need to understand and improve it. To contribute to the existing knowledge of this process, an in-depth study was conducted where 18 practitioners from eight...
The key measures of any project about its perfectness are ability to complete in the scheduled time and within the estimated cost. Cost and effort are important factors whenever a project is developed. The estimation of cost and effort is a difficult task in Agile environment. It has been observed that the current Agile methods mostly depends on an expert opinion, planning poker and historical data...
The computing modules in distributed scientific workflows must be mapped to computer nodes in shared network environments for optimal workflow performance. Finding a good workflow mapping scheme critically depends on an accurate prediction of the execution time of each individual computational module in the workflow. The time prediction of a scientific computation does not have a silver bullet as...
Early prediction of hardware complexity is essential in driving hardware/software partitioning and the automatic generation of HDL descriptions from high-level code. In fact, early prediction helps estimate the “hardware cost” of a given high-level code segment before the actual synthesis, dramatically reducing the time required for an exhaustive exploration of different design choices. Clearly, this...
Project planning requires early-on effort estimation. As such, predictions into the future are made with some degree of unavoidable uncertainty. It is likely that some of those predictions will be proven wrong. Thus, solid techniques and concrete procedures are needed to reduce the inaccuracy of estimates. This paper is motivated by practical industrial experiences. It presents a scalable technique...
