The earliest finish time for an activity is equal to the latest finish time minus the activity slack.Group startsTrue or False

Statement Analysis

1. The statement: "The earliest finish time for an activity is equal to the latest finish time minus the activity slack."
2. To assess whether this statement is true or false, we need to understand the concepts of earliest finish time, latest finish time, and slack in project management.

Relevant Concepts

1. Earliest Finish Time (EFT): This is the earliest time by which an activity can be finished based on the project schedule.
2. Latest Finish Time (LFT): This is the latest time by which an activity must be finished to not delay the project.
3. Slack (or Float): This is the total time that you can delay a task without delaying the project. Mathematically, it can be expressed as: $\text{Slack} = \text{LFT} - \text{EFT}$

Analysis and Detail

1. Rearranging the formula gives: $\text{EFT} = \text{LFT} - \text{Slack}$
2. This indicates that the earliest finish time is indeed derived from subtracting slack from the latest finish time.

Verification and Summary

1. Given the relationship defined, the statement in question is logically consistent with established project management principles.

Final Answer

True: The earliest finish time for an activity is equal to the latest finish time minus the activity slack.
