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.

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.
