Abstract In the field of software engineering, the way of Effort Estimation consists of two steps working phenomenon, first one is for the development of the estimation model for the current dataset or repository and the second one is towards the reliability of this developed model. Effort Estimation can be elaborated in terms of a required managerial activity to estimate the realistic and accurate amount of effort(expressed normally in Person- Hours, Person-Month) for the project or the set of projects. It’s also defined as efficiency that relies on the realistic utilization of the amount of modality or resources in the development of projects. In our work, we selected an integrated concept i.e. Fuzzy concept with Decision Tree to estimate the effort. Triangular membership function is used to quantify the attributes of Desharnais dataset and C4.5 decision tree is used to develop the effort model. Normally, if we apply C4.5 Decision tree on such large datasets without any tool then it took 3 to 4 month to construct an effort model, we have tried weka tool for this dataset but this tool only supports categorical target class so we made a tool ‘C4.5 data statics calculator’ which takes an excel dataset file as an input and induces a decision tree. The result from C4.5 decision tree is compared to all the methods that have been applied to this dataset in past. By our work, we found that C4.5 decision tree gives far better estimation model than other models.
