Question 1Project Initiation and Business Case

In project initiation, what is the primary purpose of a business case?

  1. To document the lessons learned from previous similar projects
  2. To record the technical design decisions made by the engineering group
  3. To justify the investment by comparing expected benefits against costs and risks Correct answer.
  4. To list the detailed work packages and schedule activities for the delivery team

Explanation

A business case exists to justify whether an initiative should be funded, weighing expected benefits against costs, risks, and constraints. It gives decision-makers the evidence needed to approve, defer, or reject the investment before significant resources are committed.

Question 2Project Initiation and Business Case

Which document formally authorizes the project manager to apply organizational resources to project activities?

  1. The risk breakdown structure
  2. The benefits realization plan
  3. The project charter Correct answer.
  4. The stakeholder register

Explanation

The project charter is the document that formally authorizes the project and empowers the project manager to commit organizational resources. It is issued by the sponsor or another authority at a level appropriate to the project's funding.

Question 3Project Initiation and Business Case

A sponsor asks for a one-page summary of why a proposed system should be funded. Which content element is most essential to include?

  1. The named individuals who will perform each development task
  2. The complete test script library for user acceptance
  3. The daily standup schedule for the delivery team
  4. The estimated costs, expected benefits, and key assumptions Correct answer.

Explanation

An investment justification must present the costs, the expected benefits, and the assumptions or constraints behind those estimates. Without this comparison, decision-makers cannot judge whether the value justifies the commitment.

Question 4Project Initiation and Business Case

What distinguishes an output from a benefit in project initiation documentation?

  1. An output is produced by the project, while a benefit is the measurable value the organization gains from it Correct answer.
  2. An output is a measurable improvement for the organization, while a benefit is a deliverable produced
  3. An output is always financial, while a benefit is always non-financial
  4. An output is approved by the sponsor, while a benefit is approved by the project manager

Explanation

Outputs are the products, services, or results the project delivers, whereas benefits are the measurable improvements or value the organization realizes from those outputs. Confusing the two leads to declaring success when deliverables exist but no value has materialized.

Question 5Project Initiation and Business Case

Who is typically accountable for ensuring that a project's business case remains valid throughout the project?

  1. The procurement officer
  2. The project sponsor Correct answer.
  3. The configuration librarian
  4. The quality assurance auditor

Explanation

The sponsor owns the business case and is accountable for confirming that the projected benefits still justify continued investment. The project manager may supply updated data, but accountability for the justification rests with the sponsor.

Question 6Project Initiation and Business Case

During initiation, a team identifies everyone who can affect or be affected by the project. What is this activity called?

  1. Scope decomposition
  2. Stakeholder identification Correct answer.
  3. Cost baseline development
  4. Quality control sampling

Explanation

Stakeholder identification is the process of determining who influences or is influenced by the project and recording their interests and influence. It is performed early so that requirements and communication approaches reflect the full set of affected parties.

Question 7Project Initiation and Business Case

A business case shows benefits of 500,000 over three years and total costs of 400,000. Which statement best reflects the analysis?

  1. The initiative has a benefit-cost ratio below one and should be rejected
  2. The initiative has a positive net benefit of 100,000 and may be viable if risks are acceptable Correct answer.
  3. The initiative is not viable because costs exceed 300,000
  4. The initiative cannot be assessed without a full schedule baseline

Explanation

Subtracting total costs from total benefits gives a net benefit of 100,000, which suggests potential viability subject to risk and assumption review. A positive net figure is necessary but not sufficient; decision-makers must still consider timing, confidence, and strategic fit.

Question 8Project Initiation and Business Case

A project manager is drafting the charter and needs to define what the project will and will not deliver. Which pair of elements should be included?

  1. Detailed activity list and resource histogram
  2. Risk response owners and contingency reserves
  3. High-level scope and high-level budget Correct answer.
  4. Test cases and defect severity thresholds

Explanation

A charter captures high-level scope boundaries together with high-level budget and milestone information so the project is bounded and authorized. Detailed activity lists, histograms, and test assets are developed later during planning and execution.

Question 9Project Initiation and Business Case

An organization uses a stage-gate approach. What is the main function of a gate review during initiation?

  1. To close supplier contracts and release vendors
  2. To assign individual development tasks to team members
  3. To perform integration testing of delivered components
  4. To confirm that the initiative still merits investment before the next stage begins Correct answer.

Explanation

A gate review is a decision point where governance bodies confirm that the business justification and readiness criteria are still satisfied before committing further resources. It can result in approval, conditional approval, deferral, or cancellation.

Question 10Project Initiation and Business Case

Which set of factors is most relevant when assessing the strategic fit of a proposed project?

  1. Alignment with organizational objectives, regulatory obligations, and capability needs Correct answer.
  2. Length of the requirements document and number of appendices
  3. Number of meetings planned, reporting frequency, and tool licenses
  4. Team member seniority, office location, and preferred working hours

Explanation

Strategic fit concerns whether the initiative advances organizational goals, satisfies mandatory obligations, and addresses genuine capability gaps. These factors determine whether the investment is worthwhile beyond mere financial return.

Question 11Project Initiation and Business Case

A sponsor insists that a project proceed despite a business case showing negative net benefit. What is the most appropriate project manager response?

  1. Refuse to manage the project and withdraw from the assignment
  2. Quietly adjust the benefit estimates so the case becomes positive
  3. Proceed without comment because the sponsor holds the budget
  4. Document the concern and escalate the decision to the appropriate governance body Correct answer.

Explanation

The project manager should record the analysis and escalate the funding decision to the governance authority that owns investment approval. Manipulating estimates would compromise integrity, and unilateral refusal or silent compliance both bypass proper decision-making.

Question 12Project Initiation and Business Case

What is the main purpose of defining measurable success criteria during initiation?

  1. To provide an objective basis for later judging whether the project achieved its intent Correct answer.
  2. To replace the need for a detailed project schedule
  3. To determine the exact number of staff required
  4. To guarantee that all risks have been eliminated

Explanation

Measurable success criteria establish the targets against which outcomes will later be evaluated, reducing ambiguity about whether the project delivered. They complement, rather than replace, planning artifacts such as schedules and staffing plans.

Question 13Project Initiation and Business Case

A project charter lists a constraint that the solution must be delivered before a regulatory deadline. How should this constraint influence initiation?

  1. It should drive the target milestones and shape the analysis of feasible options Correct answer.
  2. It should be converted into a benefit statement
  3. It should be delegated to the procurement team to resolve
  4. It should be omitted because constraints belong only in the risk register

Explanation

A hard external deadline is a key constraint that shapes target milestones and limits which delivery options are feasible. Capturing it during initiation ensures the business case and charter reflect realistic timing and trade-offs.

Question 14Project Initiation and Business Case

Which technique best helps a project manager compare several delivery options during business case development?

  1. Adopting the option with the largest documented scope
  2. Weighted scoring of options against agreed criteria such as cost, risk, and time Correct answer.
  3. Brainstorming a single preferred solution with the sponsor
  4. Reviewing the previous project's closure report only

Explanation

Weighted scoring evaluates each option against explicit criteria, making trade-offs transparent and defensible. It supports a reasoned recommendation rather than an arbitrary or single-source choice.

Question 15Project Initiation and Business Case

What does a benefit-cost ratio of 1.4 indicate about an initiative?

  1. Expected costs are 1.4 times the expected benefits
  2. The project will return 1.4 percent on investment
  3. The payback period is 1.4 years
  4. Expected benefits are 1.4 times the expected costs Correct answer.

Explanation

A benefit-cost ratio divides total expected benefits by total expected costs, so 1.4 means benefits exceed costs by forty percent. Ratios above one generally indicate a favorable relationship, though risk and timing still require review.

Question 16Project Initiation and Business Case

An organization requires that every funded initiative trace to a stated corporate objective. Which artifact best demonstrates this traceability at initiation?

  1. A benefits map linking each objective to project outputs and expected benefits Correct answer.
  2. A resource calendar showing staff availability
  3. A change log recording approved scope changes
  4. A communication plan listing report recipients

Explanation

A benefits map connects strategic objectives to the outputs and benefits the project will deliver, demonstrating why the investment is justified. It provides an auditable line of reasoning from corporate goals to project contribution.

Question 17Project Initiation and Business Case

A project charter is approved, but key assumptions behind the cost estimate are undocumented. What is the most significant risk of this gap?

  1. The stakeholder register will contain too many entries
  2. Decision-makers may approve the investment based on unexamined and possibly invalid premises Correct answer.
  3. The project manager will be unable to schedule team meetings
  4. The quality assurance team will lack test environments

Explanation

Undocumented assumptions hide the conditions on which the estimate depends, so approvers cannot test whether those conditions hold. If the premises later prove false, the cost and benefit case may collapse after resources are committed.

Question 18Project Initiation and Business Case

Two initiatives compete for the same limited funding. Initiative A has a higher benefit-cost ratio but serves a non-strategic area; Initiative B has a lower ratio but directly advances a mandated corporate priority. Which conclusion is most defensible?

  1. A must always be selected because its ratio is numerically higher
  2. Strategic necessity and mandate may outweigh a higher financial ratio, so B could be prioritized with documented rationale Correct answer.
  3. The decision should be made by the project managers of each initiative
  4. Both must be rejected because they cannot be compared

Explanation

Investment prioritization considers strategic alignment and mandatory obligations alongside financial return, so a mandated priority can justify selecting the lower-ratio option. The rationale should be documented to make the trade-off transparent and defensible.

Question 19Project Initiation and Business Case

During initiation, a stakeholder with high influence and low interest is identified. What is the most appropriate engagement approach?

  1. Keep the stakeholder satisfied with concise, targeted updates on decisions that affect them Correct answer.
  2. Send them the full set of technical design documents weekly
  3. Engage them in daily detailed working sessions on task-level progress
  4. Ignore them because their interest level is low

Explanation

High-influence, low-interest stakeholders need enough communication to remain supportive without being overloaded with detail. Concise updates focused on decisions and outcomes respect their limited interest while protecting the project from uninformed opposition.

Question 20Project Initiation and Business Case

A business case relies on benefits that will only be realized two years after project closure. What should initiation documentation include to manage this situation?

  1. An instruction to the project team to verify benefits before delivery
  2. A request to shorten the project so benefits arrive sooner
  3. A revised charter that removes the benefits from scope
  4. A benefits realization plan assigning post-closure measurement ownership and timing Correct answer.

Explanation

When benefits materialize after the project ends, a benefits realization plan must name who measures them, when, and using which metrics. This preserves accountability across the gap between delivery and value realization.

Question 21Planning and Scheduling

Which document formally authorizes a project and gives the project manager authority to begin work?

  1. The project charter Correct answer.
  2. The work breakdown structure
  3. The stakeholder register
  4. The risk register

Explanation

The project charter is issued by the sponsoring organization and formally recognizes the project's existence while granting the project manager authority to apply resources. Other planning artifacts are created after the charter and depend on it.

Question 22Planning and Scheduling

In a schedule network diagram, what does a finish-to-start dependency mean?

  1. The successor may finish only after the predecessor starts
  2. Both activities must start at the same time
  3. The predecessor may finish only after the successor starts
  4. The successor may start only after the predecessor finishes Correct answer.

Explanation

A finish-to-start relationship is the most common logical link: the successor activity cannot begin until the predecessor activity has been completed. The other options describe start-to-finish, start-to-start, or finish-to-finish logic.

Question 23Planning and Scheduling

A project manager is defining activities for a construction project. Which action best fits the Define Activities process?

  1. Breaking work packages into schedule activities with identifiable outputs Correct answer.
  2. Assigning each activity to a specific crew member
  3. Sequencing activities based on mandatory dependencies
  4. Estimating the duration of each work package

Explanation

Define Activities decomposes work packages from the work breakdown structure into the smaller schedule activities needed to produce deliverables. Assignments, sequencing, and duration estimating occur in later processes.

Question 24Planning and Scheduling

Which estimating technique uses historical data from similar past projects to estimate duration?

  1. Three-point estimating
  2. Analogous estimating Correct answer.
  3. Bottom-up estimating
  4. Parametric estimating

Explanation

Analogous estimating uses actual durations or costs from comparable prior projects as the basis for the current estimate. It is fast but less accurate than detailed techniques.

Question 25Planning and Scheduling

What is the primary purpose of a milestone in a project schedule?

  1. To buffer the critical path against delays
  2. To record the resource assigned to a work package
  3. To represent a long-duration summary activity
  4. To mark a significant point or event with zero duration Correct answer.

Explanation

A milestone is a schedule component with zero duration that highlights a significant event, decision, or deliverable completion. It serves as a checkpoint rather than as work.

Question 26Planning and Scheduling

Which term describes the sequence of activities that determines the shortest possible project duration?

  1. The baseline path
  2. The critical path Correct answer.
  3. The resource path
  4. The float path

Explanation

The critical path is the longest path through the network and therefore determines the shortest achievable project duration. Activities on it typically have zero or minimal total float.

Question 27Planning and Scheduling

A project manager needs to show planned start and finish dates for activities as horizontal bars against a calendar. Which tool should be used?

  1. A resource histogram
  2. A Gantt chart Correct answer.
  3. A cause-and-effect diagram
  4. A responsibility assignment matrix

Explanation

A Gantt chart displays schedule activities as horizontal bars positioned along a time axis, making planned dates easy to visualize. The other tools serve resource, responsibility, or quality purposes.

Question 28Planning and Scheduling

Which schedule development technique shortens duration by overlapping activities that would normally be sequential?

  1. Resource leveling
  2. Crashing
  3. Rolling wave planning
  4. Fast tracking Correct answer.

Explanation

Fast tracking compresses the schedule by performing activities in parallel that were originally planned in sequence, which increases risk of rework. Crashing instead adds resources to shorten duration.

Question 29Planning and Scheduling

An activity has an early start of day 5, an early finish of day 12, a late start of day 8, and a late finish of day 15. What is its total float?

  1. 4 days
  2. 3 days Correct answer.
  3. 7 days
  4. 0 days

Explanation

Total float equals late start minus early start (8 − 5 = 3) or late finish minus early finish (15 − 12 = 3). It represents how long the activity can be delayed without delaying the project finish.

Question 30Planning and Scheduling

Using three-point estimating with optimistic 4 days, most likely 6 days, and pessimistic 14 days, what is the PERT expected duration?

  1. 7 days Correct answer.
  2. 8 days
  3. 6 days
  4. 9 days

Explanation

The PERT weighted average is (optimistic + 4 × most likely + pessimistic) ÷ 6, which gives (4 + 24 + 14) ÷ 6 = 42 ÷ 6 = 7 days. The weighting pulls the estimate toward the most likely value.

Question 31Planning and Scheduling

A project manager must schedule an activity that can only begin after a government permit is issued. What type of dependency is this?

  1. A mandatory internal dependency
  2. A mandatory external dependency Correct answer.
  3. A discretionary internal dependency
  4. A discretionary external dependency

Explanation

The dependency is external because the permit comes from an outside agency, and it is mandatory because the law or contract requires it. Discretionary dependencies reflect preferred practices rather than hard constraints.

Question 32Planning and Scheduling

Two critical path activities both require the only available crane at the same time. Which technique should the project manager apply?

  1. Schedule baseline change
  2. Resource leveling Correct answer.
  3. Crashing
  4. Fast tracking

Explanation

Resource leveling resolves conflicts when shared or limited resources are over-allocated, often by delaying activities, which can extend the schedule. Crashing and fast tracking are compression techniques that do not resolve resource conflicts.

Question 33Planning and Scheduling

What does a lag of three days on a finish-to-start relationship indicate?

  1. The predecessor is delayed by three days of float
  2. The successor must wait three days after the predecessor finishes Correct answer.
  3. The successor may start three days before the predecessor finishes
  4. The two activities overlap by three days

Explanation

A lag adds waiting time between the finish of the predecessor and the start of the successor in a finish-to-start link. A lead, by contrast, allows the successor to start earlier.

Question 34Planning and Scheduling

A project manager is developing the schedule and wants to compare the planned schedule against the approved version after several changes. What is the approved version called?

  1. The schedule baseline Correct answer.
  2. The schedule model
  3. The schedule forecast
  4. The schedule variance

Explanation

The schedule baseline is the approved version of the schedule model that is used to compare actual performance against plan. It can only be changed through formal change control.

Question 35Planning and Scheduling

Which process involves reviewing activity durations, resource needs, and constraints to create the project schedule model?

  1. Control Schedule
  2. Sequence Activities
  3. Estimate Activity Durations
  4. Develop Schedule Correct answer.

Explanation

Develop Schedule analyzes activity sequences, durations, resource requirements, and constraints to produce the schedule model with planned dates. It integrates outputs from earlier planning processes.

Question 36Planning and Scheduling

A project has a critical path of 40 days and a near-critical path of 38 days. A risk event delays the near-critical path by 5 days. What is the new project duration?

  1. 40 days
  2. 43 days Correct answer.
  3. 38 days
  4. 45 days

Explanation

The near-critical path becomes 38 + 5 = 43 days, which exceeds the original 40-day critical path and therefore becomes the new critical path. The project duration is the longest path, so it rises to 43 days.

Question 37Planning and Scheduling

Which technique progressively elaborates schedule details for near-term work while leaving far-term work at a higher level?

  1. Precedence diagramming
  2. Parametric estimating
  3. Rolling wave planning Correct answer.
  4. Critical chain method

Explanation

Rolling wave planning plans near-term work in detail and defers detailed planning of distant work until more information is available. It is common in projects with high uncertainty.

Question 38Planning and Scheduling

An activity has 4 days of total float and 1 day of free float. If the activity is delayed by 3 days, what is the effect on the project?

  1. The successor's early start is unaffected
  2. The project finish is unaffected, but the successor's early start may be delayed Correct answer.
  3. The project finish is delayed by 2 days
  4. The project finish is delayed by 3 days

Explanation

A delay of 3 days consumes the 1 day of free float and 2 days of total float but stays within total float, so the project finish is not delayed. The successor, however, may be pushed because free float is exceeded.

Question 39Planning and Scheduling

A project manager wants to identify the longest path and the amount of float on each activity. Which technique should be used?

  1. Precedence diagramming alone
  2. Earned value analysis
  3. Monte Carlo simulation
  4. Critical path method Correct answer.

Explanation

The critical path method performs forward and backward passes through the network to determine early and late dates and float for each activity. Simulation and earned value analysis serve different purposes.

Question 40Planning and Scheduling

In the critical chain method, what is the purpose of a feeding buffer?

  1. To protect the critical chain from delays on non-critical feeding paths Correct answer.
  2. To protect the project completion date from critical chain delays
  3. To replace activity-level safety time
  4. To account for resource availability in duration estimates

Explanation

Feeding buffers are placed where non-critical paths merge into the critical chain so that delays on those paths do not consume the critical chain. Project buffers protect the overall completion date.

Question 41Planning and Scheduling

A schedule shows an activity with an early start of 10, duration of 5, and a start-to-start predecessor relationship with a 2-day lag. What is the earliest the successor can start if the predecessor starts on day 10?

  1. Day 15
  2. Day 17
  3. Day 10
  4. Day 12 Correct answer.

Explanation

In a start-to-start relationship with a lag, the successor may start the specified lag after the predecessor starts. Starting on day 10 with a 2-day lag gives day 12, independent of the predecessor's duration.

Question 42Planning and Scheduling

A project manager is deciding between crashing and fast tracking to recover a schedule delay. Which consideration most strongly favors fast tracking?

  1. Fast tracking eliminates the need for change control
  2. Crashing requires no additional resources
  3. Crashing would add cost that the budget cannot absorb Correct answer.
  4. Fast tracking always reduces risk compared with crashing

Explanation

Crashing generally increases cost by adding resources or overtime, so when budget is constrained fast tracking may be preferred despite its rework risk. Fast tracking does not inherently reduce risk and still requires change control.

Question 43Planning and Scheduling

An activity on the critical path has a pessimistic duration much longer than its most likely duration. Which statement best describes the schedule risk?

  1. The critical path may lengthen significantly if the pessimistic outcome occurs Correct answer.
  2. The activity cannot be on the critical path if its duration varies
  3. The activity has large total float that absorbs the risk
  4. The critical path is immune to this activity's variance

Explanation

Because the activity lies on the critical path, any increase in its duration directly extends the project finish unless float exists elsewhere on the path. A wide pessimistic range signals meaningful schedule risk.

Question 44Planning and Scheduling

A project manager uses a schedule network with a mandatory finish-to-start link, a 5-day lead, and a 3-day lag between two activities. What is the net effect on the successor's start relative to the predecessor's finish?

  1. The successor may start 2 days after the predecessor finishes
  2. The successor may start 2 days before the predecessor finishes Correct answer.
  3. The successor must start 8 days after the predecessor finishes
  4. The successor must start 3 days before the predecessor finishes

Explanation

A lead pulls the successor earlier while a lag pushes it later, so the net effect is a 5-day lead minus a 3-day lag, or 2 days earlier. The successor may therefore start 2 days before the predecessor finishes.

Question 45Planning and Scheduling

Which document provides the initial high-level schedule framework that is later refined into a detailed project schedule during the Planning process group?

  1. The work breakdown structure
  2. The project charter Correct answer.
  3. The schedule management plan
  4. The resource calendar

Explanation

The project charter authorizes the project and typically contains high-level milestones and target dates that later scheduling builds upon. The detailed schedule is developed afterward from the WBS, activities, and estimates.

Question 46Planning and Scheduling

A project manager is decomposing deliverables into schedule activities. Which output of the Define Activities process provides a list of all schedule activities with their identifiers and scope descriptions?

  1. The cost baseline
  2. The milestone list
  3. The activity list Correct answer.
  4. The project calendar

Explanation

Define Activities produces the activity list, which enumerates every schedule activity needed to complete the work packages, each with an identifier and a description of scope. It becomes a primary input to sequencing and estimating.

Question 47Planning and Scheduling

An activity has an optimistic duration of 5 days, a most likely duration of 8 days, and a pessimistic duration of 17 days. Using the beta (PERT) distribution, what expected duration should the project manager record?

  1. 9 days Correct answer.
  2. 8 days
  3. 12 days
  4. 10 days

Explanation

The PERT weighted average is (optimistic + 4 x most likely + pessimistic) / 6, which equals (5 + 32 + 17) / 6 = 54 / 6 = 9 days. Weighting the most likely value four times pulls the estimate toward the realistic mode while still reflecting risk.

Question 48Planning and Scheduling

A project manager needs to compress the schedule and chooses to add two experienced technicians to a critical path activity so it finishes sooner. Which schedule compression technique is being applied?

  1. Fast tracking
  2. Crashing Correct answer.
  3. Resource leveling
  4. Rolling wave planning

Explanation

Crashing adds resources to critical path activities to shorten duration, usually at increased cost. Fast tracking instead overlaps activities, while leveling and rolling wave planning address resource smoothing and progressive elaboration rather than compression.

Question 49Planning and Scheduling

An activity has an early start of day 6, a duration of 4 days, and a late finish of day 14. Assuming day-number scheduling where early finish equals early start plus duration minus one, what is the total float of the activity?

  1. 9 days
  2. 4 days Correct answer.
  3. 7 days
  4. 5 days

Explanation

Total float equals late finish minus early finish. The early finish is 6 + 4 - 1 = 9, so total float is 14 - 9 = 5 days. Float measures how long the activity can slip without delaying the project finish.

Question 50Planning and Scheduling

A project manager is analyzing a schedule network and finds two parallel paths feeding a merge point: path A totals 22 days and path B totals 19 days. A risk event could add up to 5 days to path B. What is the most accurate conclusion about the project's critical path risk?

  1. The merge point eliminates any float difference between the two paths
  2. Path B could become critical, so its float of 3 days is a buffer worth monitoring Correct answer.
  3. Path A remains critical regardless of the risk because it is longer today
  4. Both paths are equally critical because they converge at the same milestone

Explanation

Path B currently has 3 days of float relative to path A, but a 5-day potential delay exceeds that float and would shift the critical path. Near-critical paths with limited float therefore deserve active risk monitoring.
