ETRM – the Engineering Toolbox Requirements Manager
Write, link, check and approve requirements according to ISO/IEC/IEEE 29148, right in your browser. With traceability down to the test, reviews, change requests, baselines and ReqIF exchange. Free, no installation, in English, German and Spanish.
Includes the sample project “Battery Management System” to try out · no credit card required
Every feature is available in every membership
Modules like in a specification, requirements with a fixed number and attributes such as status, priority and acceptance criterion. The wording check flags vague terms, “and/or” and open items while you type. EARS sentence templates and a glossary keep sentences clear and testable.
Links connect stakeholder requirements, system requirements and test cases. The traceability matrix and the coverage check reveal gaps. When a requirement changes, its links are marked as suspect until someone has reviewed them.
Change requests show what changes, why, and which artifacts are affected. Reviews with approval or rejection per artifact ensure the four-eyes principle. The history keeps every version with its old and new value.
Freeze the state before a quote, release or acceptance as a baseline, approve it and compare two states: new, changed and removed requirements, structure and links. The result can be exported as CSV.
ReqIF for exchange with customers and suppliers, plus Excel, Word and a complete JSON backup. On re-import, ETRM shows what will change before anything is applied. The REST API is there for your own reports and automation.
Groups with roles (read, comment, edit, manage), comments and tags for daily work. The table view filters and edits many requirements at once. Metrics show status, coverage and open items in the project.
Eleven short tutorial videos walk through every feature using the sample project Battery Management System: from the first project through the artifact page, table view, wording check, traceability and baselines to data exchange, metrics, teamwork and the REST API.
The videos are currently in German; the ETRM interface itself is fully available in English.

ETRM grew straight out of everyday project work.
Many engineering projects start without a precise definition of the requirements. This lack of structure later leads to costly discussions and unnecessary loops: new requirements creep in, existing ones change by email, and at acceptance nobody knows which version applies. Budget and deadlines are then at risk.
This is where ETRM comes in: it lowers the barrier to professional requirements management as far as possible. Without installation and without training days, it brings structure to complex projects, from the first stakeholder requirement to the approved test case.
Engineering Toolbox is a project by x4projects.com. As an engineering services provider for development, design, project management and digitalization, we know what matters in practice.
Built by engineers for engineers, so that projects start with clear requirements and end with a clean acceptance.
