A researcher has a hypothesis there is a relationship between cancer and stress. He sets out to measure how stressed patients we

re before they got cancer. He creates a questionnaire asking things like, "Did you like your job?", "Did you have a happy home life?", etc. During the study the researcher noticed that those with higher stress levels before cancer did not get as much asleep as those with lower levels. This leads him to begin measuring how much sleep each person used to get on the average night. He concludes that people with stress did not get much sleep, indicating a relationship between cancer and sleep levels.

The correct answer would be, Cross-training program.

Each project team member had a back up that could fill in at a moment's notice should another team member fall by the way side. The project was able to mitigate risks in this fashion. Thanks to an aggressive Cross-training program.

Explanation:

A Cross Training Program is basically a program for employees in an organization in which employees are trained to perform tasks that are not in  their own job description.

These training are done to build the skill sets and to ensure the coverage of key job responsibilities.

This approach of cross training is very useful in minimizing the risk as this training equip employees to do tasks that are not their own job but due to such training, they are able to perform the other tasks in emergency situations and thus are highly useful in risk management.

For example if there is a task which is to be completed by an employee in the coming week and the employee falls sick, then because some other employee is trained to do the task, that task won't be suffered an will be done on time by the back up employee.

Vlad [161]

Local leaders were given a lot of authority in order to streamline decision-making, but the emperors were still the ultimate authority. To pay for their armies and other government projects, both empires collected a 25% tax on all agricultural earnings throughout their lands.
