Estimating Software Development Effort using UML Use Case Point (UCP) Method with a Modified set of Environmental Factors

Abstract- Software developers frequently depend on use cases to describe the business processes of object- oriented projects. Since use cases consists of the strategic goals and scenarios that provide value to a business domain, they can also provide insight to a projects complexity and required resources. The traditional models for cost estimation are no longer used effectively due rapid changes in technology. UML based Use case point is found to be robust one for the cost estimation having no influence of complexity of language, complexity of development platforms etc. Calculating the software development effort using Use Case Point method is found to be a suitable method. Many of the authors have done remarkable work on effort estimation using use case points by considering the external technical factors and environmental factors. In this paper the authors attempted to modify the environmental complexity factors to obtain precise and accurate result
