Question $23$

Every activity in a project network has various values that are calculated as the project's data is entered. Two of these values are

Total Slack and Free Slack. If Total Slack and Free Slack for an activity are equal, it means that

the activity is on the Critical Path

if slack is used, Total Slack and Free Slack will both be reduced and any Predecessor activity $($or activities$)$ will Not have their start delayed

if slack is used for the activity, Total Slack will be reduced by that amount, but Free Slack will remain unchanged

the activity is NOT on the critical path

if slack is used, Total Slack and Free Slack will both be reduced and any Successor activity $($or activities$)$ will Not have their start delayed

the start of any successor activity $($or activities$)$ will not be delayed as long as the Total and Free Slack values are greater than or equal to the

amount of slack used

if slack is used for the activity, Free Slack will be reduced, but Total Slack will not be reduced by the same amount
