Bill is building a project network that involves testing a prototype. He must design the prototype (activity 1), build the prototype (activity 2), and test the prototype (activity 3). Activity one is the predecessor for activity 2 and activity 2 is the predecessor for activity 3. If the prototype fails testing, Bill must redesign the prototype; therefore, activity 3 is a predecessor for activity 1. This is an example of .a. conditional statements.
b. looping.
c. having more than one start node.
d. good network development.
e. natural network flow.
