Job-readiness and assessment field guide
HMI design certificate: readiness checklist
Direct answer
The candidate can build and defend a bounded HMI project whose navigation, commands, status, abnormal response and usability are observable.
Written for automation learners, operators, technicians and hiring reviewers evaluating evidence of screen hierarchy, state, alarms, trends and operator tasks.

Role scope
Operator role, tasks, process states, display hierarchy, navigation, commands, feedback, alarms, trends, accessibility and assessment rubric.
Skills map
Field or simulated process data through quality and tag contracts to visual state, operator action and confirmed control-system response.
Core exercise
One startup, normal operation, controlled stop, alarm response and handover task completed without coaching.
Stretch case
Stale data, failed command, poor contrast, hidden mode, alarm flood, touch target, role restriction, restart and changed layout.
Troubleshooting
A process-model, tag, quality, visual-state, interaction, alarm, navigation, accessibility or assessment defect.
Portfolio evidence
Portfolio evidence reviewed alongside current HMI standards, target-platform implementation and supervised operator evaluation.
What does an HMI certificate prove?
It should prove only the published assessment scope: for example, that a learner built and explained specified screens and responses under stated conditions.
What should an HMI portfolio include?
Include the task model, display hierarchy, state matrix, alarm rationale, trend evidence, command feedback, accessibility checks, test cases and limitations.
