Open Source Software Requirements Management Tools



Arbiter is a requirements gathering and acceptance testing tool for project managers and web developers, to help ease client interaction. The project specification can be defined in word processor format as you would normally. By adding some special items, such as titled bulleted lists and highlighted text items, both a test suite and glossary can be written right into the spec. The Arbiter server will parse these documents and run the tests, reporting the results into the documents themselves. This allows the client to see project process. It also allows the developers, sitting next to the client, to add concrete executable examples of the use cases. This adds clarity and helps to settle disputes over required functionality. Using the glossary, developers can signal to the client that concepts are not well understood. Tests can be marked pending if a document contains unexplained glossary items.

Concordion is an open source framework for Java that lets you turn a plain English description of a requirement into an automated test — an active specification.


Concordion is mainly aimed at the development team that consists of analysts/clients and developers working together in an agile fashion. The analysts/clients work together with the developer to write the specifications in HTML. The developers then write their fixtures in a .NET language and Concordion runs the two together producing red/green results like a unit test.


A software toolset for the modeling and animation of e-commerce transactions. The toolset is open-source and is made up of three components; a CASE plug-in for MagicDraw™ UML (v12), a workflow engine and a centralized web client for interacting with the model via a web browser. This toolset is for business analysts who need to model the content and structure of complex messages for multiple e-business partners. After defining the messages business partners can interact -or play- with the transactions in an easy to understand way. Reduce your testing and IT development costs by validating the business requirements prior to beginning any development.

Quick Sequence Diagram Editor is a tool for creating UML sequence diagrams from textual descriptions of objects and messages that follow a very easy syntax. It supports actors, constructors, destructors, threads and on-diagram comments that can be used to represent conditions or loops.

Requirement Heap

Requirement Heap is a web based requirement management application. It allows to enter requirement in rich text, supports versioning and the management of requirements.


The RE-Tools is a model-based modeling tool. All supported notations can be used together in an integrated manner, which means functional and non-functional requirements, agents, goals, softgoals, formal goals, and objects can be related as needed.


rmtoo is a free and open source requirements management tool. rmtoo uses a different approach than most other requirements management tools: it comes as a command line tool which is optimized for handling requirements. The power of rmtoo lies in the fact that the development environment can handle the input and output files – there is no need for a special tool set environment.

UMLet - Fast UML Editor

UMLet is a UML tool aimed at providing a fast way of creating UML diagrams. UML elements are modified using text input instead of pop-up dialogs. Elements can be modified and used as templates; this way, users can easily tailor UMLet to their modeling needs. UMLet supports a variety of UML diagram types: class diagrams, use case diagrams, sequence diagrams, state diagrams, deployment diagrams, activity diagrams -- see some examples. UMLet allows users to create their own custom UML elements. An element's look can be modified at run-time by changing a few lines of Java code; UMLet then compiles the new element's code on the fly. Without leaving UMLet, users can thus create and add new element types to their diagrams.
