OLIVEIRA, Natália Pereira de. Accuracy and reproducibility study of business process points analyzes technique. 2019. 150 p. Dissertation (Master of Science) – School of Arts, Sciences and Humanities, University of São Paulo, São Paulo, 2018. Functional size measurement techniques are easily found in the literature, however, the evaluation process of these techniques are not always approached which makes its validity questionable. The Business Process Points and Analyzes (BPPA) technique was developed with the objective of adapting the Functional Points Analysis (FPA) technique of software engineering, in order to be applied in the context of business process management. BPPA was proposed so that project managers can systematically estimate the functional size of a business process automation project, however, the technique was not submitted to a consistent evaluation process, capable of presenting its benefits and limitations. The evaluation of the BPPA technique is the object of study of this dissertation that aims to consistently evaluate its capacity for accuracy and reproducibility, identifying its limitations. Thus, this dissertation presents the execution of a quasi-experiment aimed to evaluate the technique in relation to its ability to be accurate and reproducible. The quasi-experiment was performed by 58 graduate and postgraduate students, selected by convenience, who measured the functional complexity of three business process models, with support materials aid, after having undergone training on the stages of functional estimation of the technique. The results obtained with this experiment presented the low accuracy and reproducibility of the BPPA technique. Semistructured interviews were conducted with some of the participating in the experimental process in order to identify the potential limitations of the quasi-experiment to which they were submitted. The interviews were conducted by means of pre-defined questions with the objective of extracting the participants perception regarding the technique, the experimental process, the technical report, the support material, the training of estimating the functional size and other elements observed by participants. The interviews allowed us to understand that the participant subjects identified potential failure points in the process as a whole, mainly in relation to the quality of the technical report of the BPPA technique, which describes the technique and the rules of its application.
