Visualização da rastreabilidade em projetos ágeis através de dados contidos em ferramentas de apoio à gerência de projetos

Abstract

Software traceability, known for the relationship between any software engineering artifacts, brings great advantages to the development process. The information it provides helps in decision making in the face of a change, better understanding of the artifact, reusability, maintenance, forecasting of costs and deadlines, among others. With environments increasingly adept at agile methodologies, with client side-by-side giving constant feedbacks, a adequacy to these requested changes has been a common practice during system development. And, in order for changes to be made safely, tracking information helps in making decisions, with a goal in which the change does not bring inconsistencies, introduce errors, and generate system failures. Some project management tools give support to traceability elements. However with several data that can be provided with such a practice, it is dificult to interpret them, especially when they are presented only textually. Knowing that the visualization of information brings the possibility of an analysis with large volumes of data in a fast and clear way, o ering a safer decision making and, allowing to discover information previously unseen, it is possible to verify in the literature techniques of visualization of information of traceability. However, in order to suggest a visualization, it is necessary to know beyond the data that will be shown. To achieve that, it is needed to consider the information pillars exposed in the academy (problem to be approached, what, when, and who to visualize) and then get an adequate visualization. With this purpose, this work performs interviews in the industry to identify and respond to the pillars of information considered in the proposal of a traceability visualization. Then, an analysis based on Grounded Theory in data is done. Then, in the context of traceability, the pro les, needs and problems described, and artifacts generated in agile environments are identi ed, and it is studied the bibliography about information visualizations. As a result, a discussion and suggestion of appropriate visualization for traceability information is made based on the suggestions in the literature and data collected from the interview. Later, with Heuristics created, an evaluation of the project management tools that integrate the platform of hosting and versioning of data Github is made, to see if they provide the noticed visualization of traceability information.
