Write the specification, not a spreadsheet.
Author requirements as structured, auto-numbered documents with every item embedded where it belongs. Links, attributes and history sit one panel away. Bring in what you already have: a PDF or Word specification through rule-based import, or a DOORS or Polarion export through ReqIF.
- Structured documents with embedded work items
- PDF and Word import with rules you control
- ReqIF and Excel import for migration
