Empirical analysis on productivity prediction and locality for use case points method

Use case points (UCP) method has been around for over two decades. Although there was a substantial criticism concerning the algebraic construction and factor assessment of UCP, it remains an efficient early size estimation method. Predicting software effort from UCP is still ever-present challenge. The earlier version suggested using productivity as cost driver, where fixed or few pre-defined ratios have widely agreed. While this approach successful when not enough historical data available, no longer acceptable because projects are different in terms development aspects. Therefore, better to understand relationship between other variables. This paper examines impact locality approaches on prediction multiple environmental factors used partitioning produce local homogeneous either based their influential levels clustering algorithms. Different machine learning methods, including solo ensemble construct models data. results demonstrate that created surpass use entire Also, show conforming to the hypothetical assumption necessarily requirement the success locality.
