Software Size and Effort Estimation

339.015 1KV Zivkovic Block Begin: 28.5.2009

Many software projects fail - project are late, cost too much or do not deliver the expected functionality. In this course the focus is on software size and effort estimation. Both parameters could improve project planning activities and consequently influence that the project is finished on time and within the budget. Software size is an elementary metrics that is used to calculate project effort, duration and costs. Therefore we will focus on measuring software size in object-oriented projects using the Function Point Analysis method. Some other methods will also be mentioned during the course like MK II FPA, COSMIC and Use Case Points. Finally software size will be transformed to effort using different models like COCOMO II and ISBSG repository.

Goals: To become familiar with size and effort estimation process, available methods and their use in practice
