Um estudo de caso para avaliar o impacto do uso de code review em aspectos de qualidade de um sistema real.

Abstract

Software development is usually guided by a set of activities/phases for the product to reach the expected goal. During these phases, good practices aimed at maintenance and quality assurance, such as code review, are essential, even more so in scenarios of rapid growth and product approval, which require agile development. This work consists of carrying out a case study to evaluate the impact on code quality aspects of a real system at Hospital Israelita Albert Einstein, after the team introduced code review activities in its development process. For this, quantitative (e.g., number of bugs) and qualitative (e.g., reliability) metrics were used, comparing two moments of the project, pre and post the use of code review. In general, we found a tendency to reduce bugs and improve code quality. The main characteristics of the discussions between author and reviewer have changed and, unanimously, developers believe in the positive impact of code review on the project.
