ISO 27001 implementation

Answer:

Although knowledge on PM and BA can make easier the ISO 27001 implementation, this knowledge is not mandatory, because there are at least three approaches for an ISMS implementation:
- Use your own staff to implement the ISMS (this is the case where knowledge on PM and BA is most needed)
- Use a consultant to perform most of the effort to implement the ISMS
- Use a consultant only to support the staff on specific issues, leaving the organization's staff with most of the implementation effort.

Each one of them has their advantages and disadvantages. For more information, I suggest you the following ma terials:
