ISO 22301 documents and competencies

- the replacement scheme
- the task documenting
as you said in on of the articles?

Answer: Through replacement scheme (where during normal operation different people perform the same activity) you ensure that more than one person knows how to perform an activity, so in case the main operator is unavailable other person can resume his activities.

Regarding documentation, it ensures that knowledge will be retained by the organization in case the person who performs it leaves the organization, as well as it helps to define a standard way of doing things, supporting the replacement scheme.

2. Is there any specific requirement in the standard to regarding these 2 points?

Answer: There is no requirement for replacement scheme in ISO 22301, however clause 7.2 (competence) requires persons are competent for doing work that affects business continuity, and this can be used to support the replacement scheme practice.

Regarding documentation, clause 7.5.1, requires documentation of information determined by the organization as being necessary for the effectiveness of BCMS. So, if a critical activity is considered important to the organization for business continuity, then it should be documented.
