ISA/IECISA/IEC 62443IEC 62443: Risk Assessment & Asset Owner RequirementsEASYFree question
The IEC 62443 maturity model assigns Maturity Level 1 to a process that is performed but undocumented and dependent on individual expertise. What is the conventional name for this level?
- A.Managed
- B.Improving
- C.Defined
- D.Initial
Why D is correct
Maturity Level 1 is labelled Initial, meaning the activity may occur but is ad hoc, undocumented, and reliant on individual skill rather than repeatable process. Higher levels add management, documentation, and continuous improvement. The model parallels CMMI staging concepts.
