| - | The growing need to maintain software systems is one of the main challenges of modern software engineering. The interest in maintenance and evolution of software has increased in recent years under the pressure of the trade-offs between developing and releasing new versions of software on the market. | + | The continuing need to keep (i.e., identifying and correcting defects and improving the quality of the internal code) and development (i.e., adding new features) software systems is a major challenge in modern software engineering. Several studies show that activities related to software evolution or maintenance have been responsible for a considerable cost on the development process, reaching in some cases, 90% of the total cost. |
| - | Before performing any software maintenance or evolution, however, it is fundamental to understanding the software to be modified. Software visualization is a subarea of data analysis and software engineering which makes use of views to facilitate software understanding, either through the analysis of a single version of the system or its entire history of versions. | + | The interest for software evolution and maintenance has been intensified in recent years, face to the pressure for a shorter time between the development and to release new software versions on the market. Another factor that has contributed to increase investment in software evolution and maintenance activities is the frequent advent of new execution environments (i.e., Web computing, ubiquitous computing and cloud computing), new development paradigms (i.e., Aspect-Oriented Software Development - AOSD and Service-Oriented Architecture - SOA) and new types of access (i.e., from mobile devices tablets, gestural interfaces, etc.). |
| - | The **Workshop on Software Visualization, Evolution and Maintenance (VEM)** aims to integrate the communities in the areas of Software Visualization, Software Maintenance, and Software Evolution. This edition is the second year of VEM, but it has been built from two other workshops, namely: | + | Before performing any evolution and maintenance, however, is fundamental to understand the software to be modified. Software comprehension is not a trivial task. It involves complex cognitive processes and may consume in some cases, up to 50% of the total maintenance time. |

| + | Software Visualization is a subarea of Information Visualization and Software Engineering, which makes use of visual resources to facilitate software comprehension, either through the analysis of a single version system or your entire version history. | ||

| + | Although there is a clear intersection of issues and research challenges involving areas of Software Visualization, Evolution and Maintenance, until recently these areas were the focus of two separate events organized by Brazilian Software Engineering community, usually in different places and dates. They are: | ||
