How to Choose a Requirements Management Tool: A 12-Point Checklist

Most teams start writing requirements in a Word document or a spreadsheet, and for a small project that is fine. The trouble starts later: two people edit different copies, nobody knows which version the customer approved, and a test cannot be traced back to the requirement it proves.

A requirements management tool exists to solve exactly those problems. But tools differ widely, and the most expensive one is rarely the right one. Use the twelve questions below to decide what you need before you compare products.

Do you need a dedicated tool at all?#

A document is enough when one person writes the spec, the project is short, nothing is regulated, and nobody needs to prove later which requirement was tested. Students writing a single course specification are usually in this situation.

You need more than a document as soon as several people edit at once, the customer has to approve a version, requirements change after approval, or an auditor may ask you to show the link from requirement to test.

The 12-point checklist#

• Unique, stable IDs — every requirement keeps its ID (for example REQ-042) even when it moves or is reworded, so tests, tickets and emails can refer to it.
• Structure and free text together — a real specification mixes headings, explanations, tables and diagrams with the requirement statements themselves.
• Traceability links — you can link a requirement to its parent, to related requirements and to the tests or tickets that cover it, and see what is not covered yet.
• Versions and baselines — you can freeze an approved state ("baseline"), keep working, and compare any two states to see exactly what changed.
• Review and approval — reviewers can comment, and approval is recorded per requirement or per section, not in an email thread.
• Permissions — viewers, editors and approvers have different rights, and external reviewers can read without editing.
• Quality checks — vague words ("fast", "user-friendly", "etc."), missing numbers and untestable statements are flagged before review, not after.
• Import — you can bring in the Word documents and spreadsheets you already have instead of retyping them.
• Exchange formats — export to PDF and Word for readers, to Excel or CSV for analysis, and ReqIF (the standard XML exchange format) when a customer or supplier uses another tool.
• Templates — common document types (software or hardware specifications, Lastenheft and Pflichtenheft) start with a sensible outline.
• Learning curve — a new team member or a student can write a first requirement within minutes, without a training course.
• Data location and security — you know where the data is stored, who can access it, and how you get all of it back out.

How to run a fair trial#

Do not judge a tool by its feature list. Take a real specification you already have — ten to twenty pages is enough — and do the same five things in every tool you consider: import it, fix three vague requirements, link two requirements to tests, freeze a baseline, change one requirement and compare against the baseline.

Time how long each step takes and note where you needed help. The tool that makes those five steps boring is the one your team will keep using.

• Import an existing document and check what survived (headings, tables, numbering).
• Rewrite three vague requirements and see whether the tool helps you spot them.
• Link requirements to tests and find the ones without coverage.
• Freeze a baseline, change something, and compare the two versions.
• Export the result in the format your customer or professor expects.

Tips for students#

For a course project the tool matters less than the habit. Give every requirement an ID, write each one as a single testable sentence with "shall", and keep a short change log. Those three habits are exactly what professional tools automate, so you will recognise them immediately in your first engineering job.

If your course asks for a Lastenheft or a software requirements specification, start from a standard outline instead of a blank page — see our guide to the SRS structure.

Where Requify fits#

Requify is a requirements tool built around the checklist above: requirements with stable IDs inside a normal document structure, links between requirements, baselines you can compare, a review workflow, Word and ReqIF import, export to PDF, Word, Excel and ReqIF, and AI checks that flag vague or untestable wording. You can try it with your own document and run the five-step trial yourself.
