Lead implementer and lead auditor

a) Should I take ISO 27001 LA or Implementation course ?
b) What's the difference between the two ?

Answer: Let's start with the differences:
- ISO 27001 Lead Implementer – this certification recognizes people who have competency on the ISO 27001 implementation process.
- ISO 27001 Lead Auditor – this certification recognizes people who have competency on auditing an ISMS against ISO 27001 requirements and want to become certification auditor (and with this provides more confidence to an organization for being certified).

So, the decision about which one to take will depend on your professional purposes. If you plan to work on an information Security Management System certification process, then you should consider the Lead Implementer certification. If you plan to ensure the operation of an ISMS, then you should consider the Lead Auditor certification.
