Answer: Personal comparison
Step-by-step explanation:
When it comes to the Control Process, entities are allowed to use several comparison methods when comparing task results with objectives.
These include:
- the Historical method where current performance is compared to past performance
- the Relative comparison method where the organization's performance is compared against a benchmark of other organizations in the industry.
- Engineering comparison where schedules are used to ensure that activities finish on time.
Personal comparison is not an acceptable method.
