First do a PERT chart for the information given in the table above. The days in the end should be 82. Next task is to complete the table which should result in the activity time shortened by atleast 24 days. Then do a PERT chart for the new shortened information in the table.

You should be able to explain to me what you did because I have to write a report on it.
