Keep every requirement, interface and risk connected.

applmain is one workspace for systems engineering teams to manage requirements, integrations and risks, and to see how a change in one affects the others.

Traceability example A requirement is allocated to an interface, and a risk is linked to both. REQ-142 · Requirement Brake command acknowledged within 150 ms ICD-07 · Interface CAN bus: brake controller to gateway RSK-031 · Risk, open Message latency rises under bus load
A requirement, the interface that carries it, and the risk that threatens it, linked.

Three modules, one shared model

Use one on its own or all three together. They read from the same project data, so nothing is copied between spreadsheets.

Requirements management

Write, organize and track requirements from stakeholder needs down to component level.

  • Hierarchies, baselines and version history
  • Verification method and status per requirement
  • Change requests with impact preview

Interface and integration management

Define how systems connect, and track whether each connection has been integrated and tested.

  • Interface control documents and N² views
  • Owners and agreements on both sides
  • Integration plans and test status

Risk management

Record risks where the work happens, score them, and keep mitigations moving.

  • Likelihood and consequence matrix
  • Mitigation actions with owners and dates
  • Risks tied to requirements and interfaces

When something changes, see what it touches

A late change to one requirement can break an interface and raise a risk nobody was watching. In applmain those items are linked, so you can see the full chain before you approve the change.

Trace coverage, open risks and unresolved interfaces show up in one project view, ready for design reviews.

  1. Requirement changesResponse time moves from 200 ms to 150 ms.
  2. Linked interfaces flaggedThe bus interface is marked for review by its owners.
  3. Related risks re-scoredLatency risk is reopened with the new threshold.
  4. Reviewers notifiedEveryone affected sees the change and approves or comments.

Built for systems engineering, useful well beyond it

Anywhere teams build something from many connected parts, the same three questions come up: what must it do, how do the parts connect, and what could go wrong.
