Doorstop vs Siemens Polarion REQUIREMENTS

Doorstop manages textual requirements alongside source code in version control. It stores requirements and other linkable items as YAML files in directories that form documents, then organizes those documents into a tree and can validate traceability across it. It publishes document hierarchies and trace matrices as plain text, HTML, LaTeX, or Markdown; templates can shape output, and HTML and LaTeX publishing use them. Requirements can be imported or exported as YAML, CSV, TSV, or Excel files. Doorstop requires Python 3.10 or later and Git or another version control system, and it can be added to a Poetry project. It runs on Linux, macOS, and Windows, with API and self-hosted options, including standalone web-server or WSGI deployment. An experimental desktop GUI handles basic editing. The tool is free at free and licensed under LGPLv3. Baseline support and version history are listed, but approval workflows are not.

Siemens Polarion REQUIREMENTS manages requirements for complex systems from initial authoring through approval and ongoing lifecycle changes. Its LiveDocs provide structured online spaces for writing, validating, and maintaining specifications. Automatic change control helps teams trace requirement updates during development, while data can be reused or branched across parallel projects, sequential efforts, and product lines. Permissions can be organized by role, user, project, or group, with LDAP support. Teams can configure workflows and templates for methods including Agile, Scrum, Kanban, traditional, and hybrid approaches; Siemens says these can support processes aligned with FDA, FAA, CMMI, ISO, IEC, and SPICE. Listed connections include Jira, Azure DevOps, IBM DOORS, MATLAB Simulink, Teamcenter, and Mendix, alongside REST and web services APIs. Requirements can be exchanged in Word, Excel, ReqIF, PDF, XML, and HTML formats. Polarion ALM is available on a customer-managed server, while Polarion X is a cloud option. Pricing is on request, and installation includes a 30-day evaluation license.
