Evaluation of Reproducibility and Accuracy of the Business Process Point Analysis Technique

Abstract

Techniques of functional size measurement are easily found in the literature, however, in the evaluation process of these techniques is not always approached which makes its validity questionable. The evaluation of the Business Process Point Analysis (BPPA) technique is the object of study of this article that aims to consistently evaluate its reproducibility and accuracy, identifying its limitations. BPPA was proposed so that project managers can systematically estimate the functional size of a business process automation project. Thus, this article presents the execution of a quasi-experiment realized with 58 graduate and postgraduate students, who measured the functional size of three business process models. The results of this experiment present the low reproducibility and accuracy of the technique as well as its limitations.
