Scheduling Professional Study Guide and Documents References:The Budgeted Cost of Work Scheduled (BCWS) is the planned value of all tasks scheduled during a specific period. It is a measure used in earned value management to assess schedule adherence.

Option A defines Budgeted Cost of Work Performed (BCWP).

Option B defines the total project budget (BAC).

Option C defines the expected total cost, which is Estimate at Completion (EAC).

This answer is consistent with earned value methodologies and their application in project controls​​.

 Estimating Activity Durations:

The critical factors are crew size, labor hours, and the standard workday.

Cost estimation is not directly required to calculate durations.

 Evaluation of Options:

Option A: Incorrect. Crew size is needed for productivity estimation.

Option B: Incorrect. Labor hours are directly tied to durations.

Option C: Incorrect. Workday hours define the available time.

Option D: Correct. Cost is not directly linked to duration

 Construction Life Cycle Phases:

Common phases: planning and design, installation (execution), and turnover/start-up.

Claims and disputes may arise during the project but are not a defined phase of the construction life cycle.

 PSP Study Guide References:

The study guide outlines standard phases without including claims and disputes as a formal phase​.

 Conclusion: The correct answer is A, as claims and disputes are not an inherent phase of the construction life cycle.

 Interpret the Narrow Band at "Y":

The narrow band at "Y" is located on a part of the schedule where activities have been delayed or slowed down.

Such delays typically indicate resource limitations (e.g., insufficient manpower or equipment).

 Reasoning:

No evidence of rework or activity inactivity is explicitly shown in the diagram.

Resource limitations are common in network diagrams to explain such periods.

 Cross-Verification:

Option B: Incorrect. No evidence of rework exists.

Option C: Incorrect. Activity inactivity does not fit the context.

Option D: Incorrect. Sufficient information is provided.

Option A: Correct. Resource limitation fits the observed diagram behavior.

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 months 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.

Retaining existing logic means preserving the original relationships and dependencies defined in the schedule. Even if progress is recorded out of sequence, calculations adhere to the pre-established logic unless explicitly changed.

Option B reflects adjustments for out-of-sequence progress but contradicts the original logic requirement.

Option C imposes restrictions that do not align with typical CPM calculations.

Option D is incorrect as the concept exists​​.

The PSP Study Guide discusses the importance of maintaining logic integrity in CPM scheduling​.

To constrain a project's end date, a Finish-No-Later constraint is applied to the last activity. This ensures any slippage results in negative float, signaling delays relative to the fixed deadline.

Option A and B apply to earlier constraints, which are not relevant for controlling the project's end date.

Option D applies a constraint to the first activity, not the project finish.

This concept aligns with controlling project deadlines as described in the PSP Study Guide​.

 Crashed Schedule Predecessors to Activity 2004:

Activity 2004 (River Diversion to Pipeline) depends on completion of:

1001 (Preliminary Civil Work).

2001 (River Diversion Stage 1).

2002 (River Diversion Stage 2).

2003 (River Diversion Dam).

 Exclusion of Other Activities:

Activity 2007 is not part of the crashed schedule's direct predecessor chain.

Other options include duplicated or incorrect entries.

 PSP Study Guide Reference:Logical sequence analysis confirms these predecessors (Ref: PSP Study Guide, Chapter 2A: Activity Sequencing and Critical Path Analysis).

Start Date: April 1, 2002.

Duration of Activity 7001 (Normal Schedule): 48 days.

Workweek: 5-day workweek (Monday to Friday).

No holidays are mentioned in the problem.

Given Data

Step 1: Calculate Total Working DaysUsing a 5-day workweek:

Determine the number of full weeks in 48 days:48÷5=9 weeks with 3 additional workdays.48 \div 5 = 9 \, \text{weeks with 3 additional workdays.}48÷5=9weeks with 3 additional workdays.

Total work period = 9 weeks + 3 workdays = 45 weekdays.

Starting from April 1, 2002 (Monday):

Add 9 full weeks: April 1 + 9 weeks = May 31, 2002 (Friday).

Add the remaining 3 workdays:

Monday, June 3.

Tuesday, June 4.

Wednesday, June 5, 2002.

Step 2: Calculate Calendar End Date

Step 3: Validate AnswerThe finish date for Activity 7001 is June 5, 2002.

 Situation Analysis:

Proofing of the product manual requires 15 additional days.

This impacts the Print Product Manual (Activity F), which is a critical path activity.

 Maintaining the Availability Date:

To prevent delays in the product release (Activity H), the additional 15 days for proofing must be offset.

Reducing the printing duration (Activity F) by 5 days ensures the schedule stays on track.

Expediting other activities like manufacturing or packaging would not directly compensate for the proofing delay.

 Cross-Verification:

Option A: Incorrect. Delaying product release impacts availability.

Option B: Incorrect. Packaging is not a direct predecessor of the product release.

Option D: Incorrect. Delaying manufacturing has no impact on proofing.

Option C: Correct. Expedites the critical path by compensating for the delay.
