Summary
The Heuristic Requirements Assistant (HeRA) is the primary research demonstration tool that illustrates the concepts of our groups requirements engineering research. HeRA has an extension mechanism that allows to rapidly evaluate new techniques. Extensions can be classified as follows:
- Construction Components: Allow to create requirements artifacts. Examples are the UseCaseExtension, RequirementsExtension?, and GlossaryExtension?.
- Argumentation Components: Analyze the requirements artifacts and give heuristic feedback: the CritiqueExtension? evaluates if the requirements documentation adheres to best practices and wording rules. The GlossaryExtension? gives hints on technical terms that should be defined in a glossary. The SecReqExtension? helps to identify and refine security relevant requirements in a specification.
- Inference Components: These type of components derive different kinds of models from requirements. This allows requirements engineers to take a new perspective and find inconsistencies in the requirements. Examples for this type of extensions are UMLUseCaseExtension, EPCExtension, and EffortEstimationExtension?.
We have already used HeRA in many projects. We invite you to evaluate it. Keep in mind that this is a research prototype. We are currently approaching a stable beta release, but still lack the stability of commercial software.
Contact & Accounts
We really appreciate feedback! We are always interested to evaluate HeRA's concepts in an industrial setting, so feel free to contact us with feature requests, questions, or suggestions!

News
October 2010
- After one year of bug-fixing we finally put together a new release (Version 0.7). There is still some work to do (e.g. licensing), so the download remains password protected. Of course, Beta-Tester for our Use Case Editor are welcome. Please contact Eric Knauss for the password!
January 2010
- EclEmma?: A new and simpler way to compute HeRA's testcoverage: ( http://www.eclemma.org/index.html). See https://trac.se.uni-hannover.de/trac/hera/wiki/BestPractices#ComputeTestCoverage for more details.
November 2009
- In order to increase overall quality of HeRA, we plan to increase the process of resolving tickets. The FinishTicketChecklist requires contributers to increase the version of the extension, use static code analysis, and collect some basic metrics for the extension.
October 2009
- 13. October 2009: Todays workshop was the kick-off to a new phase of HeRA's development. The HeRA core-team now consists of four people. We decided to focus even more on creating a stable version based on (a subset of) the existing functionality. Furthermore, we plan to organize this Project? more strictly.

Documentation
Tool Demonstration
- The Demoscript gives a short overview on how HeRA is intended to be used.
- The Slides of the presentation of HeRA at ICSE 2009
- The HeRA Poster at ICSE 2009
Demonstration Video
We have a [ demonstration video of HeRA]'s core functionality online. There is still no sound, but we are working on it.
User Documentation
We started to collect UserDocumentation here. Please maintain the documentation on this page for any extension you work on (or with).
In addition, we startet a short PresentationScript. This should help to quickly demonstrate the main ideas of HeRA. Please maintain this section for your extension as well!
