| Bug | Deviation of a program from its expected result. |
| Defect | An error created by a programmer when writing code. |
| Crowbar | A tool that uses fault localization available at www.crowbar.io |
Here, the project is described along with its requirements and domain model. This document is updated continuously and developers should contribute with more documentation.
Software debugging have a big impact in Software development costs. Developers need to focus their resources to fix defects faster, by knowing the components that are more faulty. Schwa is a project that aims to give defect information, by Mining Software Repositories. Existing fault localization tools can benefit from Schwa defect probabilities (a priori), such as Crowbar.

| Developer | Is a Software Engineer that needs Schwa to track defects. |
| Crowbar | Is a tool that relies on Schwa to obtain defect probabilities. |
| ID | Name | Description | Points | Priority |
|---|---|---|---|---|
| US01 | GIT repositories | As a developer, I can analyze Git repositories, because is the most popular CVS. | 5 | High |
| US02 | Java Projects | As a developer, I can analyze my Java projects, because is a popular programming language. | 8 | High |
| US03 | Interface | As a developer, I can invoke Schwa by command line and get a Sunburst chart, because is an effective way of displaying defects. | 3 | Medium |

| R01 | Performance | It should scale to big repositories. |
The domain that Schwa operates, is a repository that can be easily modeled in the following diagram. A diff is a change made in a commit to a component, that can be for an instance, a method added, modified, removed or renamed.
