Managing Change and Using Stop Work

This workshop provides a process to evaluate change and determine when and how to exercise Stop Work Authority.

Change Will Happen

Follow a process to evaluate when and how to exercise Stop Work Authority.

We need more guidance beyond "plan for change."

You'll learn the steps to evaluate if a change is significant enough to stop and re-evaluate the plan. Just as important, you'll learn when it's time to restart work.
