 Late Finish (LF) Transition Rule:

Late finish (LF) is calculated by adding one day to the early finish (EF) of the final activity.

EF of Activity 11001 is given, and the late finish is simply EF+1EF + 1EF+1.

 Cross-Verification with PSP Guidelines:

PSP methodologies state that late finish is derived from the forward pass using early finish logic, with specific adjustments based on activity relationships (Ref: PSP Stu dy Guide, Chapter 2A: Forward and Backward Pass Calculations).

Impact of Changing Activity E ' s Duration:

Activity E ' s new duration = 4 months.

The critical path passes through Activities A → C → D → E → H → I.

Recalculate Project Duration:

Original duration with E = 3 months: 19 months.

Increasing E to 4 mo nths does not impact the overall path since it remains within the critical path ' s time allowance.

Overall project duration remains 19 months .

Cross-Verification:

Option B: Incorrect. Assumes additional delays.

Option C: Incorrect. Overestimates delays.

Option D: Incorrect. Miscalculates path changes.

Option A: Correct. Matches revised critical path duration.

 Shape of Cumulative BCWS:

The Budgeted Cost of Work Scheduled (BCWS) reflects a cumulative expenditure curve over time, typically shaped like an " S " .

 Explanation of the S-Curve:

Initially slow expenditure, acceleration duri ng peak work, and tapering off near completion.

 Verification with PSP Guidelines:

The PSP Study Guide discusses BCWS as part of earned value management (Ref: PSP Study Guide, Chapter 1D: Earned Value Analysis).

Defining the execution plan is the foundational step in creating a CPM schedule. This involves understanding the project ' s scope of work and outlining how it will be executed to meet project objectives.

Option A (bar chart) is a visualization step but does not address planning the sequence or scope execution.

Option C (resources) comes later in schedule development after the scope and plan are defined.

Option D (logic diagram) is a subsequent step that relies on t he execution plan​​.

The PSP Study Guide emphasizes scope and execution planning as critical first steps​.
