According to ISO 22301:2019, Clause 6.2, the organization must establish business continuity

objectives at relevant functions and levels. The business continuity objectives must be consistent

with the business continuity policy, measurable, monitored, communicated, and updated as

appropriate. The organization must also retain documented information on the business continuity

objectives. One of the elements that should be included in the documented information is

the timescale for the task completion. The timescale is the period of time within which the task or

activity must be completed, such as hours, days, weeks, or months. The timescale helps to define the

expected performance and results of the business continuity management system (BCMS), and to

evaluate the progress and effectiveness of the implementation and operation of the

BCMS. Reference: ISO 22301:2019, Clause 6.2; ISO 22301 Auditing eBook, Chapter 4.2.2.
