 Understand Free Float:

Free float is the time an activity can be delayed without delaying the start of its immediate successor.

 Review Activity F in the Diagram:

Activity F has a successor that starts later, providing room for 2 months of free float.

 Cross-Verification:

Option A: Incorrect. Overestimates the float.

Option B: Incorrect. No float is incorrect for F.

Option C: Incorrect. 1 month is insufficient.

Option D: Correct. Matches the calculated free float for Activity F.

An effective schedule is one that is realistic, collaborative, and accept ed by key stakeholders involved in project execution.

Gaining consent and agreement ensures buy-in, facilitates implementation, and minimizes disputes (Option B)​.

Frequent updates (Option A) are essential for tracking but are insufficient without team agreement.

Contract specifications (Option C) govern compliance but do not guarantee effective field use.

Large contingencies (Option D) may reduce accountability and create inefficiencies in project management.

Collaboration and stakeholder involvement, a s emphasized in the PSP Study Guide, are essential for schedule usability​.

 Activity Duration in Crashed Schedule :

For Activity 2002, the crashed duration is 28 days (refer to the table).

 Start Date :

The start date is August 12, 2001 .

 Adding the Duration :

Starting from August 12, add 28 days. Ensure to account for weekends or holidays if the calendar used excludes them.

 Finish Date Calculation :

Starting on August 12 and counting 28 days gives the finish date as September 8, 2001 .

The Project Scope Statement typically includes:

Project objectives.

Justification.

Deliverables.

However, the contract between the contractor and owner is not included directly in the scope statement. Instead, it serves as a separate legal document governing the project ' s terms and conditions. This distinction is clear in project scope management practices dis cussed in the PSP materials​​.

 Definition of a Critical Path Method (CPM) Schedule:

CPM schedules are based on network diagrams that logically link activities, showing the sequence and dependencies between them.

These schedules identify the critical path, which is the longest path through the network, determining the project ' s shortest possible duration.

 Evaluation of Options:

Option A: Incorrect. While CPM schedules do include tasks and timelines, the defining featu re is the logical interconnection of activities.

Option B: Incorrect. CPM schedules are not limited to " risky " work; they show all activities.

Option C: Incorrect. CPM schedules use network diagrams, not just graphical representations.

Option D: Correct. T he network diagram is the key characteristic of CPM schedules.

A

 Critical Path Charact eristics :

The critical path is the sequence of activities that determines the overall project duration.

It represents the longest duration path through the network and typically has zero float unless delays or constraints introduce negative float.

 PSP S tudy Guide References :

Critical path analysis is a foundational concept in schedule management, as covered extensively in the PSP guide​.

 Analysis of Options :

Option A : Correct. The critical path always has the longest duration.

Option B : Zero float is common but not universal due to constraints or delays.

Option C and D : Negative float describes specific scenarios but does not define the critical path universally.

 Conclusion : The correct answer is A , as the critical path is the longest-duration path through the network.

Analyze Activity 2001 in the " Normal " Schedule:

Activity 2001 ( " River Diversion Stage 1 " ) has a duration of 92 days under the " Normal " schedule.

The logic column shows it has a Successor ID of 2002 , and a Finish-to-Start (FS) relationship wit h no lag. This indicates that Activity 2002 will begin immediately after Activity 2001 finishes.

Identify Concurrent Activities Using the Schedule Logic: To determine concurrency, we need to look for activities that overlap in time with Activity 2001 durin g its duration. Concurrent activities must either:

Start before Activity 2001 finishes, or

Finish after Activity 2001 starts.

Review Activities in the Normal Schedule:

Activity 1001 ( " Preliminary Civil Work " ) :

Has a duration of 85 days , starts before Activity 2001, and overlaps with it.

Logic: Its successor is Activity 2001 (Start-to-Start [SS] relationship), confirming the overlap.

Activity 1000 ( " General Conditions " ) :

Duration is 1072 days. However, this is an overarching activity, and its inclusion is not specific to being concurrent with Activity 2001.

Activity 7001 ( " Permanent Roads " ) :

Starts much later, after Activity 2001 ends, and thus is not concurrent.

Activity 2003 ( " River Diversion Dam " ) :

Starts after Activity 2001 completes (FS relationship), so it is not concurrent.

Conclusion: The only activity that overlaps and runs concurrently with Activity 2001 in the " Normal " schedule is Activity 1001 .

The sum of all budgets for work scheduled to be accomplished within a specific time period is referred to as the Budgeted Cost of Work Scheduled (BCWS) . It represents the planned value of work to be performed during the reporting period.

Option A (Estimate at Completion - EAC) refers to the projected final cost of the project.

Option B (Budget at Completion - BAC) is the total project budget.

Option C (Bud geted Cost of Work Performed - BCWP) refers to the earned value.

This definition aligns with earned value management concepts covered in the PSP Study Guide​.
