Updating the program network diagram

After adding the new WBS elements to mitigate risks or incorporate opportunities and receiving an approved estimate, you send the updated program WBS information to the external schedule. All the newly added WBS work packages and their resource requirements appear in the network diagram in the external schedule. As a program manager, you add the new WBS work packages to the existing network chains. Also, you can update the network diagram to reflect the updated estimate due to risk and opportunity incorporation.
