Mixed Deck — All CST Topics Flashcards

A CST professional encounters an unfamiliar situation while performing cost-loaded schedule integration duties. What is the most appropriate first action?

Answer: Consult relevant standards, guidelines, or a qualified supervisor before proceeding

When facing unfamiliar situations in cost-loaded schedule integration, the most appropriate action is to consult relevant standards, guidelines, or a qualified supervisor. This ensures safety, accuracy, and compliance while building professional knowledge.

What is resource allocation in project management?

Answer: Distributing resources effectively across tasks

Resource allocation in project management involves identifying, assigning, and managing the various resources (e.g., personnel, equipment, materials, budget) required for project tasks. The primary goal is to distribute these resources efficiently and optimally across all tasks. This ensures that every activity has what it needs to be completed on time and within budget, preventing both over-commitment and under-utilization.

In schedule compression, crashing is most effective when applied to activities that have:

Answer: The lowest cost slope (least cost to shorten per unit of time)

Crashing prioritizes critical path activities with the lowest cost slope — the least additional cost per unit of schedule reduction.

When should a schedule contingency reserve be released during a project?

Answer: When a specific risk event occurs and its associated impact is realized

Schedule contingency is released when the risk event it was reserved for actually occurs, ensuring the buffer is used intentionally rather than consumed arbitrarily.

In project scheduling, what does 'total float' represent?

Answer: The amount of time an activity can be delayed without delaying the project finish

Total float is the amount of time an activity can be delayed from its early start without delaying the project completion date.

Which tool best helps visualize dependencies between project tasks?

Answer: Network Diagram

A Network Diagram is the best tool for visualizing dependencies between project tasks. It graphically represents tasks as nodes and uses arrows to show the logical relationships and sequence in which tasks must be completed. This visual representation helps project managers understand the flow of work, identify critical paths, and manage the interconnections between various project activities effectively.

In a PDM (Precedence Diagramming Method) network, a Start-to-Start relationship with a lag of 2 means:

Answer: The successor cannot start until 2 days after the predecessor starts

An SS+2 relationship requires the successor to wait 2 days after the predecessor has started before the successor can begin.

What AACE International recommended practice provides guidance on schedule risk analysis?

Answer: AACE RP 57R-09

AACE RP 57R-09 provides a framework for integrated cost and schedule risk analysis, including Monte Carlo simulation methods for project schedules.

A scheduler is reviewing a schedule where the same milestone appears twice — once as a deliverable and once as a contractual event. Which practice should be used?

Answer: Merge them into a single milestone with appropriate predecessor and successor links

Duplicate milestones representing the same event should be consolidated into a single milestone to avoid logical inconsistencies and duplicate reporting.

Which type of dependency represents a required, contractual, or physical limitation between activities?

Answer: Mandatory dependency

Mandatory dependencies (hard logic) are inherent in the nature of the work or required by contract and cannot be changed.

In MS Project, what is the effect of linking tasks with a 'Start-to-Start' (SS) dependency with a 3-day lag?

Answer: The successor cannot start until 3 days after the predecessor starts

An SS+3 lag means the successor task's earliest start is 3 days after the predecessor task begins.

What distinguishes Primavera P6 in scheduling software?

Answer: Managing large, complex projects across multiple sectors

Primavera P6 is distinguished as a robust enterprise project portfolio management (EPPM) software specifically designed for managing large, highly complex projects and programs across multiple sectors. It offers advanced capabilities for scheduling, resource management, cost control, and risk analysis, making it a preferred choice for industries like construction, engineering, and aerospace where intricate project coordination is essential.

In the context of schedule variance & delay analysis, what role does continuous professional development play for CST practitioners?

Answer: It ensures practitioners remain current with evolving standards, technologies, and best practices

Continuous professional development is essential in schedule variance & delay analysis because it ensures CST practitioners remain current with evolving standards, technologies, and best practices, maintaining competency throughout their careers.

What is the 'Data Date' in P6 and how does it affect schedule calculations?

Answer: The date through which actual progress is reported; it divides past actuals from future projections

The Data Date (also called status date) is the point in time separating reported actual progress from the forward-projected schedule.

When importing an XER file into Primavera P6, what potential conflict must the scheduler address?

Answer: Activity IDs or project codes may already exist in the database, causing duplicates

Duplicate Activity IDs or project numbers in the receiving P6 database can cause merge conflicts, requiring the scheduler to choose to update or add new records.

What can cause resource overallocation?

Answer: Assigning multiple tasks to a single resource beyond capacity

Resource overallocation occurs when a resource, such as a team member or piece of equipment, is assigned more work than they can realistically complete within a given timeframe. This typically happens when a single resource is scheduled to work on multiple tasks concurrently, exceeding their available working hours or capacity. It leads to burnout, delays, and decreased quality of work.

Which scenario would most likely cause the critical path to shift to a different path during project execution?

Answer: A non-critical activity experiencing a delay greater than its Total Float

When a non-critical activity's delay exceeds its Total Float, that activity and its path become critical, shifting the critical path.

Which network diagramming method uses nodes to represent activities and arrows to show dependencies?

Answer: Precedence Diagramming Method (PDM)

PDM (also called Activity-on-Node) places activities in boxes/nodes and uses arrows solely to represent logical relationships.

In Primavera P6, what does 'Retained Logic' scheduling option do when an out-of-sequence activity is encountered?

Answer: Retains original logic and does not allow the successor to progress past the predecessor

Retained Logic holds the dependency and prevents a successor from progressing further until its predecessor is complete, even if the successor has already started.

In MS Project, what is the purpose of the 'Split Task' feature?

Answer: It interrupts a task's timeline to reflect a period of no work while preserving total duration

Splitting a task places a gap in its Gantt bar, representing a scheduled interruption in work while keeping the total assigned work unchanged.
