Size and Flexibility Metrics for E-Learning System

E-learning system is a comprehensive software package that supports for teaching the subject, testing, simulation, discussion or other significant aspect. In software system development process, estimation is playing very important role. The success of any software project largely depends on effective estimation of project effort, time and cost. Estimation helps in setting realistic targets for completing the project. The widely used software estimation techniques like LOC, FP, and COCOMO are not effectively supported for estimating E-Learning systems because the structure and components of E-learning system is different and also the current estimation methodologies given generic solution to all kind of software system. The characteristics and specifications of subject oriented software like E-learning systems not fully come under the limit of existing estimators. They provide wrong estimates and lead customer dissatisfaction due to incompleteness, loss and delay. So in this research paper, along with the concepts of FPA, the new size metric is proposed for E-learning system estimation. This Technique considers the document part and application part of E-Learning system very effectively and estimates the size. In addition with size metric new flexibility metric introduced, it is used to calculate flexibility of software.
