How MSA works, end to end
One linked model takes you from engineering data to certification-ready evidence.
- Hazard → function → test traced
- One method on every project
- Runs offline, on-prem
How you do it in MSA
6 steps
- 1
Create a project and import
Start a machine or process project from your existing engineering data.
- 2
Assess risk
Identify hazards per ISO 12100, score risk and apply the 3-step method.
- 3
Define and verify safety functions
Get PLr or SIL, then verify the achieved PL or SIL per function.
- 4
Plan validation tests
Generate FAT/SAT matrices from the safety functions and record results.
- 5
Review and export
Route items through review, then export Word, PDF or Excel evidence.
- 6
Change and regenerate
See what a change affects and regenerate the affected outputs.
