• Identify the ES, EF, LS, LF and slack times in the table using the critical path method. (You may fill in the table above)

• During the initial stages of the project, a new set of requirements were discovered that would extend the process and layout design activity from 2 to 6 months. The operations group which initiated these requirement changes argues that they would not impact the project duration. Is this true? Justify your answer.
