The earliest finish time for an activity is equal to the latest finish time minus the activity time. True False<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

False.<\/strong><\/p>\n\n\n\n

The earliest finish time (EFT) for an activity is not<\/strong> determined by the latest finish time (LFT) minus the activity duration. Instead, it is calculated based on the earliest start time (EST) and the activity duration.<\/p>\n\n\n\n

Correct Formula:<\/strong><\/h3>\n\n\n\n

[
EFT = EST + Duration
]<\/p>\n\n\n\n

Explanation:<\/strong><\/h3>\n\n\n\n

In project scheduling and network analysis (e.g., Critical Path Method or CPM), activities are evaluated based on their earliest and latest times to determine the project schedule.<\/p>\n\n\n\n

    \n
  1. Earliest Start Time (EST):<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • The earliest<\/strong> time an activity can start, considering the completion of all its predecessor activities.<\/li>\n\n\n\n
    • Determined in the forward pass<\/strong> of the network diagram.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Earliest Finish Time (EFT):<\/strong><\/li>\n<\/ol>\n\n\n\n
          \n
        • The earliest time an activity can be completed.<\/li>\n\n\n\n
        • Formula:<\/strong>
          [
          EFT = EST + Duration
          ]<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Latest Finish Time (LFT):<\/strong><\/li>\n<\/ol>\n\n\n\n
              \n
            • The latest<\/strong> time an activity can finish without delaying the project.<\/li>\n\n\n\n
            • Determined in the backward pass<\/strong> of the network diagram.<\/li>\n<\/ul>\n\n\n\n
                \n
              1. Latest Start Time (LST):<\/strong><\/li>\n<\/ol>\n\n\n\n
                  \n
                • The latest time an activity can start without delaying the project.<\/li>\n\n\n\n
                • Formula:<\/strong>
                  [
                  LST = LFT – Duration
                  ]<\/li>\n<\/ul>\n\n\n\n

                  Why the Given Statement is Incorrect<\/strong><\/h3>\n\n\n\n

                  The statement suggests that:
                  [
                  EFT = LFT – Duration
                  ]
                  However, EFT is calculated from EST, not LFT<\/strong>. LFT is used for calculating LST, which is different from EFT.<\/p>\n\n\n\n

                  Thus, the correct relationship is:<\/p>\n\n\n\n

                    \n
                  • Earliest Finish Time (EFT) = Earliest Start Time (EST) + Duration<\/strong><\/li>\n\n\n\n
                  • Latest Start Time (LST) = Latest Finish Time (LFT) – Duration<\/strong><\/li>\n<\/ul>\n\n\n\n

                    Since the given statement incorrectly relates EFT and LFT, the answer is False<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
