Should you build or buy Requirements Management & ALM?
Requirements management and ALM software tracks a product's requirements from definition through design, risk and test, keeping the trace links, baselines and sign-offs that regulators expect. Engineering teams in automotive, aerospace and medical-device programs use it to prove, on demand, that every requirement was built, verified and reviewed.
Buy the ALM when audits, suppliers and variants are in play; docs-as-code is credible for bounded, Git-centric scope.
Build it, buy it, or bridge?
When building makes sense
Building a requirements and traceability layer in Git makes sense for a team whose scope is bounded and whose engineers already work in pull requests. The Zephyr Project runs its safety-oriented requirements this way, using StrictDoc for authoring and rendering, with new and changed requirements reviewed through pull requests that need approval from the safety working group before they merge. Sphinx-Needs and Doorstop follow the same docs-as-code pattern: requirements as text files, versioned like code, linked to design and test through the same repository. What this path does not yet carry is the audited half of the job: formal baselines with e-signatures, supplier data exchange, and the tool-qualification paperwork a certification body accepts without pushback. Building earns its keep when the program is small enough that one team owns the whole trace and doesn't need to hand evidence packages to an external auditor or a supplier network.
When buying makes sense
Buying earns its keep the moment a program needs formal baselines, e-signatures, or a supplier exchange format like ReqIF that a certification body will actually accept. IBM's DOORS Next lists from $164 per user per month for its Professional cloud tier, and Jama Connect, Codebeamer and Polarion price similarly for suites that bundle review workflows, variant management and audit logging most Git-based setups still have to build by hand. The buy case is strongest for automotive, aerospace and medical-device programs where ISO 26262, DO-178C or IEC 62304 auditors assess the organization's controlled process and expect a specific kind of evidence package. It's also the safer default when multiple suppliers must exchange requirements in a standard format, since a homegrown trace scheme has no obligation to interoperate with anyone else's tooling.

Frequently asked
What is requirements management and ALM software?
It's the layer that proves, to an auditor or a certification body, that every requirement in a regulated product was actually designed, built and tested, with a documented chain from the requirement to the code, the risk analysis and the test that verified it.
Can a Git-based setup really replace a licensed ALM suite?
For narrow scope, yes: the Zephyr Project keeps its safety-oriented requirements in StrictDoc with Git pull-request review from its safety working group instead of a licensed tool. What it hasn't publicly demonstrated is carrying formal baselines and e-signatures through an actual DO-178C or ISO 26262 product certification.
Why does DOORS Next cost so much per user?
IBM's Professional SaaS tier starts at $164 per user per month, which reflects a single-tenant cloud environment plus the traceability, baseline and Global Configuration Management features that large regulated programs use daily. Smaller teams often find the seat cost hard to justify against a narrower tool.
What's the real gap between Git-native tools and the commercial suites?
Tool qualification and audit evidence. Sphinx-Needs and StrictDoc handle the trace links well, but no publicly documented team has carried that setup through a passed DO-178C or ISO 26262 audit the way DOORS, Polarion or Codebeamer are built to support.
What are the main requirements management and ALM vendors?
Representative vendors include IBM Engineering Requirements Management DOORS Family, Jama Connect. B4 Pro includes the category score and the full vendor list.
