Question 1Schedule Planning

In schedule planning, what is the primary purpose of a work breakdown structure (WBS)?

  1. To decompose project scope into manageable components that can be planned and controlled Correct answer.
  2. To sequence construction activities by their earliest start dates
  3. To assign contractual responsibility for every payment milestone and deliverable to the owner or designer
  4. To calculate the project's cost contingency from historical data

Explanation

The WBS decomposes project scope into manageable deliverables and work packages. Schedule activities are then tied to WBS elements for planning, estimating, and control. It is not a sequencing tool or a cost contingency calculation.

Question 2Schedule Planning

Which schedule level typically presents a one-page executive summary with major milestones and key dates?

  1. Level 4 short-interval schedule
  2. Level 1 summary schedule Correct answer.
  3. Level 5 detailed execution schedule
  4. Level 3 construction control schedule

Explanation

Level 1 is the executive summary schedule with major milestones and key dates. Detail increases through Levels 2, 3, 4, and 5, with Level 3 often serving as the project control schedule and Levels 4-5 used for execution. The level should match the audience and control purpose.

Question 3Schedule Planning

A milestone in a schedule model is best characterized as:

  1. An activity with a fixed duration equal to the reporting period
  2. A summary activity that rolls up all work packages and cost accounts for reporting
  3. A non-work calendar exception used to record holidays
  4. A zero-duration event marking a significant point or achievement Correct answer.

Explanation

A milestone is a zero-duration marker for a significant event, decision, or achievement. It has no work and no resources, though it can have dates and constraints. Milestones are used for reporting and contractual requirements.

Question 4Schedule Planning

A finish-to-start relationship between Activity A and Activity B means:

  1. B cannot start until A has finished Correct answer.
  2. B can finish before A starts
  3. A and B must finish at the same time
  4. A can finish only after B starts

Explanation

Finish-to-start means the successor cannot begin until the predecessor finishes. It is the most common dependency in construction and engineering schedules. Calendar and lag rules then determine the actual start date.

Question 5Schedule Planning

A lead applied to a finish-to-start relationship does what?

  1. Delays the start of the successor until after the predecessor has completely finished
  2. Removes the dependency between the two activities
  3. Forces the successor to finish before the predecessor
  4. Allows the successor to start before the predecessor finishes Correct answer.

Explanation

A lead is a negative lag that allows a successor to begin before the predecessor finishes. It can shorten the schedule but may increase risk if work overlaps prematurely. Leads should be used only with clear justification.

Question 6Schedule Planning

Why are project and activity calendars defined during schedule planning?

  1. To establish the contract's payment terms and retention amounts
  2. To identify working and nonworking periods that affect activity timing Correct answer.
  3. To determine the organizational breakdown structure for cost accounts
  4. To calculate the earned value performance index and cost variance for every activity

Explanation

Calendars define working days, shifts, holidays, and nonworking periods. They affect activity start and finish dates and the conversion of durations to calendar dates. Resource and project calendars must be applied consistently.

Question 7Schedule Planning

A schedule baseline is best described as:

  1. A temporary schedule created before scope is defined
  2. The latest updated working schedule used for daily field coordination and short-term lookaheads
  3. A list of all resource rates used to price schedule activities
  4. The approved version of the schedule against which performance is measured Correct answer.

Explanation

A schedule baseline is the approved schedule model used to compare actual and forecast performance. Changes to it should follow formal change control. Working schedules and updates are separate from the baseline.

Question 8Schedule Planning

In schedule planning, activity duration is the:

  1. Number of resources assigned to an activity
  2. Amount of elapsed calendar time between two project milestones, including nonworking days
  3. Total project duration from authorization to closeout
  4. Working time needed to complete an activity under defined conditions Correct answer.

Explanation

Activity duration is the working time required to complete the activity under the assigned calendar and defined conditions. It is usually expressed in workdays or work periods, not total elapsed calendar days. It excludes nonworking periods unless the calendar defines them as working.

Question 9Schedule Planning

In the critical path method, the critical path is the:

  1. Path that contains every milestone in the project schedule
  2. Longest continuous path through the network, which governs project duration Correct answer.
  3. Path with the highest total estimated cost in the schedule
  4. Sequence of activities that has the largest number of skilled resources assigned to it

Explanation

The critical path is the longest continuous path through the network, so it determines the shortest possible project duration. Activities on it typically have the least total float, often zero unless constraints create negative float. It can change as logic or durations change.

Question 10Schedule Planning

What distinguishes free float from total float?

  1. Free float is measured in calendar days, while total float is measured only in work periods on the project calendar
  2. Free float can become negative under date constraints, while total float can never become negative in a schedule
  3. Free float is slip that does not delay the successor; total float is slip that does not delay project finish Correct answer.
  4. Free float applies only to summary activities and milestones, while total float applies only to detailed activities

Explanation

Free float is the amount an activity can slip without delaying any successor's early start. Total float is the amount it can slip without delaying the project finish date. Free float is always less than or equal to total float.

Question 11Schedule Planning

Resource leveling differs from resource smoothing primarily because leveling:

  1. Requires reducing the project scope and re-baselining before any scheduling can continue
  2. May extend the project duration to resolve resource over-allocation Correct answer.
  3. Never changes the project completion date
  4. Applies only to noncritical activities with positive float

Explanation

Resource leveling resolves over-allocation by adjusting activity timing, which can extend the project finish. Resource smoothing instead seeks to flatten resource use within available float without changing the completion date. Leveling is used when resource limits are mandatory.

Question 12Schedule Planning

Which item belongs in the schedule basis document?

  1. The contractor's bid price for each schedule activity
  2. A complete copy of the accounting ledger
  3. The personal performance ratings of every member of the scheduling and project controls team
  4. Key assumptions, constraints, and methodologies used to develop the schedule Correct answer.

Explanation

The schedule basis records the assumptions, constraints, methods, calendars, and data sources used to build the schedule. It gives reviewers and future users traceability for schedule decisions. It is not a financial ledger or personnel record.

Question 13Schedule Planning

What is the main scheduling benefit of a consistent activity coding structure?

  1. It automatically calculates activity durations from historical data
  2. It guarantees that the critical path will not change during execution
  3. It enables filtering, grouping, and reporting of activities by common attributes Correct answer.
  4. It eliminates the need to update the schedule after baseline approval and change control

Explanation

Activity codes assign consistent attributes such as area, phase, discipline, or responsibility. They let users filter, group, sort, and report schedule data without changing the logic. Codes support analysis but do not replace schedule updates.

Question 14Schedule Planning

A 'start no earlier than' constraint on an activity does what?

  1. Allows the activity to start regardless of its predecessor logic
  2. Prevents the activity from starting before its predecessor finishes
  3. Forces the activity to start exactly on a specified date
  4. Restricts the activity from starting before a specified date Correct answer.

Explanation

A start-no-earlier-than constraint sets a date before which the activity cannot begin. It can override or supplement logic and may create float or date-driven effects. It differs from a mandatory start-on-date constraint, which fixes the start date.

Question 15Schedule Planning

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

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

Explanation

The PERT expected duration is (optimistic + 4 × most likely + pessimistic) ÷ 6. Here, (4 + 24 + 14) ÷ 6 = 42 ÷ 6 = 7 days. This weighted average gives more influence to the most likely estimate.

Question 16Schedule Planning

Schedule contingency is intended to:

  1. Cover known work that was omitted from the WBS
  2. Address residual risk and uncertainty in the project completion date Correct answer.
  3. Fund the owner's scope changes after baseline approval
  4. Replace missing activity logic whenever predecessor relationships are unknown or undefined

Explanation

Schedule contingency is time added to the schedule to cover residual risk and uncertainty, often derived from risk analysis. It is not a substitute for missing scope or for unapproved scope changes. It protects the completion commitment.

Question 17Schedule Planning

An open-ended activity in a schedule network is one that:

  1. Contains no resource assignments but has complete logic
  2. Lacks a predecessor or successor relationship, creating a logic gap Correct answer.
  3. Has more than one calendar assigned to its work period
  4. Exceeds its original duration estimate by more than 10 percent during progress updates

Explanation

Open-ended activities lack a predecessor or successor, creating a logic gap. They can distort float and critical path calculations because the network is incomplete. Schedulers should close open ends with logical ties or explain why they remain.

Question 18Schedule Planning

Rolling wave planning is most appropriate when:

  1. All project scope and activity details are fully known at the start
  2. The schedule must be baselined once at project initiation and never revised afterward
  3. Resource leveling has eliminated all float from the schedule
  4. Near-term work can be detailed while later work remains at a higher level Correct answer.

Explanation

Rolling wave planning progressively elaborates the schedule as more information becomes available. Near-term activities are detailed, while far-term work remains in summary form. It suits projects with evolving scope.

Question 19Schedule Planning

What is the primary role of a scheduling specification in schedule planning?

  1. To list the names of every worker assigned to each activity
  2. To establish the project's accounting chart of accounts
  3. To define required scheduling methods, formats, and submission standards Correct answer.
  4. To serve as the project's quality assurance inspection plan for field construction work

Explanation

A scheduling specification sets the required scheduling methodology, software, formats, review cycles, and submission standards. It promotes consistency across schedules and contractors. It is not a field inspection plan or accounting structure.

Question 20Schedule Planning

Which pair correctly describes crashing and fast tracking?

  1. Crashing removes dependencies; fast tracking increases activity durations
  2. Crashing reduces scope; fast tracking extends the project calendar
  3. Crashing adds resources or cost to shorten duration; fast tracking overlaps activities Correct answer.
  4. Crashing deliberately overlaps activities to save time; fast tracking adds resources and cost to activities

Explanation

Crashing shortens duration by adding resources or cost to critical activities. Fast tracking overlaps activities that would normally be sequential, which can increase risk. Both are schedule compression techniques.

Question 21Schedule Planning

A schedule has Activity A on a 5-day calendar and Activity B on a 7-day calendar, connected finish-to-start with no lag. Which statement is most accurate?

  1. Activity B will always start on the same calendar day that Activity A finishes, regardless of either calendar
  2. Activity A's duration automatically converts to a seven-day equivalent with no effect on any relationship dates
  3. The finish-to-start relationship becomes invalid unless both activities are assigned the same project calendar and workweek
  4. Calendars are converted in the calculation, so workday counts may differ across the relationship Correct answer.

Explanation

Scheduling engines use each activity's calendar to convert work periods to dates. With different calendars, the same number of workdays represents different elapsed time, so the interface must be calculated carefully. The finish-to-start link still means B follows A, but dates are not a simple one-to-one workday transfer.

Question 22Schedule Planning

Negative total float in an updated schedule most directly indicates that:

  1. The activity has more resources assigned to it than its predecessor activity has available
  2. The project or a constrained path is forecast to finish later than a required date Correct answer.
  3. The activity's duration was estimated using PERT rather than deterministic CPM calculations
  4. The schedule contains no critical path

Explanation

Negative total float arises when an activity's late finish is earlier than its early finish because of an imposed date or constraint. It signals that the forecast completion is beyond a required milestone or project finish date. The scheduler should review logic and constraints before accepting it.

Question 23Schedule Planning

When lags are used on the critical path, which statement is correct?

  1. Lags never affect the critical path because they are not activities
  2. Lags eliminate the need for total float calculations
  3. Lags can consume time and may become part of the controlling sequence Correct answer.
  4. Lags convert the critical path into a noncritical path by adding float to every activity

Explanation

Lags represent waiting or elapsed time between activities and can extend the controlling path. They are not activities, but they affect early and late dates and can become part of the critical sequence. Positive lags should be used sparingly and reviewed.

Question 24Schedule Planning

A schedule review finds many activities with lags on finish-to-start relationships and several hard constraints. What is the best interpretation?

  1. The schedule's critical path is guaranteed to be stable
  2. The schedule has too much detail and should be reduced to a milestone list
  3. The schedule may have logic substitution that can mask true dependencies and drive dates Correct answer.
  4. The schedule is fully optimized for resource leveling and therefore needs no further review

Explanation

Lags and hard constraints can replace missing logic and force dates, which may hide real dependencies. This can produce artificial critical paths and make float values unreliable. Schedule reviews should test whether open logic or constraints are driving dates.

Question 25Schedule Planning

In a Monte Carlo schedule risk analysis, what does the distribution of project completion dates primarily reflect?

  1. Only the cost contingency approved for the project baseline
  2. Combined effects of uncertainty in activity durations and logic across iterations Correct answer.
  3. The resource histogram without consideration of duration variability
  4. The single deterministic critical path calculated from the most likely duration of every activity

Explanation

Monte Carlo simulation samples duration and other uncertain inputs repeatedly to produce a distribution of completion dates. The result reflects combined uncertainty across activities and logic, not a single deterministic path. It supports contingency and risk-informed decisions.

Question 26Schedule Planning

In the classical schedule planning sequence, activity sequencing is performed immediately after which process?

  1. Resource leveling
  2. Schedule development
  3. Duration estimating
  4. Activity definition Correct answer.

Explanation

The sequence runs from activity definition to activity sequencing, then duration estimating, then schedule development. Activities must first be identified from the work breakdown structure before logical relationships can be established between them. Sequencing therefore depends on a complete activity list.

Question 27Schedule Planning

Which statement best characterizes a finish milestone in a project schedule?

  1. It has zero duration and marks a significant point or event. Correct answer.
  2. It represents a work package that can be decomposed further.
  3. It carries a short duration and consumes committed resources.
  4. It acts as a summary bar spanning the whole project.

Explanation

A milestone is a zero-duration marker used to flag a significant event, decision, or contractual point such as substantial completion. Because it has no duration and no resources, it cannot be measured by percent complete. Progress against a milestone is judged as either achieved or not achieved.

Question 28Schedule Planning

A hammock (summary) activity is included in a schedule primarily to:

  1. Define the critical path through the spanned work
  2. Replace detailed logic for the work it spans
  3. Provide a resource-loaded activity for earned value
  4. Aggregate duration and cost across the activities it spans Correct answer.

Explanation

A hammock or summary activity rolls up the activities between its driving predecessors and successors, so its dates and totals are derived rather than entered. It is used for reporting and for checking aggregate duration or cost at a summary level. It never substitutes for the detailed logic that actually drives those totals.

Question 29Schedule Planning

A start-to-start relationship with a three-day lag between Activity A and Activity B means that:

  1. B may finish three days after A starts
  2. B may start three days after A finishes
  3. B may start three days before A starts
  4. B may start three days after A starts Correct answer.

Explanation

A start-to-start relationship ties the start of the successor to the start of the predecessor, and the lag adds time to that tie. B therefore cannot begin until three days have elapsed from A's start. The finish of either activity is not constrained by this relationship.

Question 30Schedule Planning

In a typical multi-level schedule hierarchy, a Level 3 schedule is best described as:

  1. A six-week look-ahead extracted from the working schedule
  2. A control schedule with detailed activities and logic used to measure progress Correct answer.
  3. A cost-loaded schedule used only to verify invoices
  4. An executive summary of key milestones used for board reporting

Explanation

Level 1 is usually a milestone or executive summary, Level 2 a management summary, and Level 3 the control schedule that carries detailed activities, logic, and resources for performance measurement. Lower levels add execution and working detail. Look-aheads are extracts of the working schedule rather than a tier of the hierarchy.

Question 31Schedule Planning

Activity A has a duration of 3 days and is a predecessor to both B (4 days) and C (6 days). Both B and C are predecessors to D, which has a duration of 2 days. All relationships are finish-to-start with no lags. What is the total float of Activity B?

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

Explanation

The path through C is 3 + 6 + 2 = 11 days and governs the project, while the path through B is 3 + 4 + 2 = 9 days. Total float on the B path equals 11 − 9 = 2 days. B can slip two days before it begins to drive the project completion date.

Question 32Schedule Planning

In schedule planning, total float on a network path is normally understood to be:

  1. Owned by the activity owner, who may spend it without notifying others
  2. Owned by the client and unavailable to the project team
  3. Owned by the project and managed in the interest of the whole project Correct answer.
  4. Owned by the functional manager who supplies the resource

Explanation

Total float is a shared buffer held at project level because consuming it on one path can make that path critical. Individual activity owners therefore cannot spend float unilaterally. Its use is normally coordinated through the scheduler or project manager so that the overall completion date is protected.

Question 33Schedule Planning

A schedule health check reports circular logic among Activities X, Y and Z. The most likely cause is:

  1. A missing predecessor on an activity that starts the project
  2. A lag applied to a finish-to-start relationship
  3. A chain of relationships in which a successor is also, directly or indirectly, a predecessor Correct answer.
  4. A calendar assigned to an activity that is also assigned to the project

Explanation

A loop exists when following relationships from an activity leads back to that same activity, which can never be calculated by CPM. It usually arises when logic is added or revised without checking the downstream path. The remedy is to break the cycle by removing or reversing the offending relationship.

Question 34Schedule Planning

During a CPM backward pass, an activity with two successors and no lags takes its late finish from:

  1. The later of the two successors' late finish dates
  2. The earlier of the two successors' late start dates Correct answer.
  3. The later of the two successors' late start dates
  4. The average of the two successors' late start dates

Explanation

The backward pass sets each activity's late finish to the minimum of its successors' late starts, adjusted for any lag. Using the minimum keeps all successors from being delayed. The resulting late finish is then reduced by the activity's duration to obtain its late start.

Question 35Schedule Planning

A near-critical path in a schedule is best described as a path that:

  1. Contains more activities than the critical path
  2. Carries little total float and could become critical after minor slippage Correct answer.
  3. Runs parallel to the critical path and shares all of its resources
  4. Contains no activities that carry total float

Explanation

Near-critical paths have total float small enough that ordinary variation in progress could consume it and make them drive the completion date. They are usually identified by applying a float threshold, such as paths with ten days or less of float. Monitoring them prevents surprise criticality during execution.

Question 36Schedule Planning

A time-phased resource histogram produced during schedule planning is used primarily to:

  1. Compare period-by-period resource demand with available supply Correct answer.
  2. Calculate total float on the network paths
  3. Determine the early and late dates of each activity
  4. Establish the logical sequence between activities

Explanation

The histogram is derived by spreading each activity's resource requirement across its scheduled dates. It shows where demand peaks exceed or fall short of the resource availability defined in the calendars. This view supports decisions about staffing, hiring, or adjusting the schedule.

Question 37Schedule Planning

When setting the level of detail for a control-level schedule, activities are usually sized so that:

  1. Their durations equal the duration of the whole work package they belong to
  2. All activities in the schedule are given the same duration
  3. Only the longest activity in each phase is included in the schedule
  4. Their durations are short relative to the update cycle Correct answer.

Explanation

Activities should be short enough that real progress can be observed and reported within each update period, which keeps percent complete and remaining duration credible. Excessively long activities hide slippage until it is too late to respond. The exact limit depends on the reporting cycle and the nature of the work.

Question 38Schedule Planning

A CPM network uses different calendars for different activities. Which statement about the critical path is correct?

  1. It is fixed by activity durations and cannot shift during an update
  2. Calendars affect only resource loading and never change the calculated critical path
  3. It is the longest path in elapsed calendar time, so calendars can change it Correct answer.
  4. It is always the path with the largest sum of activity durations in work days

Explanation

When calendars differ, activity durations in work days must be converted to elapsed calendar time before paths are compared. A path with more work days can finish earlier in calendar time if it runs across non-working periods on its calendar. Criticality must therefore be evaluated in a common time frame.

Question 39Schedule Planning

During a progress update, a successor activity has already started before its predecessor finished. If the scheduler applies retained logic, the schedule will:

  1. Re-sequence the successor so that it starts immediately after the data date in all cases
  2. Retain the predecessor's remaining work and delay the successor's remaining work Correct answer.
  3. Split both activities so that no out-of-sequence relationships remain in the schedule
  4. Ignore the predecessor's remaining work and let the actual start of the successor drive the dates

Explanation

Retained logic preserves the original network logic: the unfinished portion of the predecessor stays in the schedule and the successor's remaining work is scheduled after it finishes. This protects the forecast from being optimistically driven by out-of-sequence starts. Progress override, by contrast, drops the predecessor's remaining constraint on the successor.

Question 40Schedule Planning

Activity A has a duration of 5 days and is a predecessor to B (3 days) by finish-to-start. A is also a predecessor to C (2 days) by finish-to-start with a 2-day lag. Both B and C are predecessors to D (4 days) by finish-to-start. What is the calculated project duration?

  1. 12 days
  2. 14 days
  3. 13 days Correct answer.
  4. 11 days

Explanation

The path through B is 5 + 3 + 4 = 12 days. The path through C includes the lag: 5 + 2 + 2 + 4 = 13 days, which governs the project. The critical path therefore runs through C, and B carries one day of total float.

Question 41Schedule Development

Which path through a schedule network determines the project's minimum completion time?

  1. It contains the greatest number of activities.
  2. It consumes the most resources.
  3. It has the longest total duration. Correct answer.
  4. It has the highest total cost.

Explanation

The critical path is the longest path through the network and therefore sets the shortest possible project duration. Its activities carry the least total float, usually zero when the project finish date is fixed. Path length is measured in time, not in activity count, cost, or resource quantity.

Question 42Schedule Development

What does a finish-to-start dependency require?

  1. The predecessor may start only after the successor starts.
  2. The successor must finish before the predecessor may start.
  3. The successor may start before the predecessor finishes, subject to a lag.
  4. The predecessor must finish before the successor may start. Correct answer.

Explanation

A finish-to-start relationship requires the predecessor activity to be complete before the successor can begin. It is the most common logical relationship used in precedence diagrams. Overlap would require a different relationship type or a negative lag.

Question 43Schedule Development

What does total float represent for a scheduled activity?

  1. Time an activity can be delayed without delaying project completion. Correct answer.
  2. Time between the activity's early finish and the project's start.
  3. Difference between the activity's duration and its resource availability.
  4. Time an activity can be delayed without affecting any successor's early start.

Explanation

Total float is the amount of time an activity can be delayed without delaying the project completion date, assuming other activities proceed as planned. It equals late finish minus early finish or late start minus early start. Float is shared along a path, so consuming it can reduce the float available to other activities on that path.

Question 44Schedule Development

Which description best characterizes a milestone in a schedule model?

  1. An activity whose duration equals its lag.
  2. A summary activity that rolls up several work packages.
  3. A significant point or event with zero duration. Correct answer.
  4. A resource-loaded task with no predecessor.

Explanation

A milestone marks a significant point or event and has zero duration, so it consumes no time or resources. Milestones are used to flag approvals, handoffs, contractual dates, and phase completions. They are not work activities and do not carry effort.

Question 45Schedule Development

In schedule logic, what is a lag?

  1. The time an activity can slip without affecting the project.
  2. The overlap permitted between two activities.
  3. A scheduled delay between a predecessor and a successor. Correct answer.
  4. The difference between early and late dates.

Explanation

A lag is a deliberate delay inserted between a predecessor and a successor, such as waiting for concrete to cure before the next trade starts. It is expressed in the same time units as activity durations and modifies the logical relationship. A negative lag is called a lead and creates overlap.

Question 46Schedule Development

What is a schedule baseline?

  1. The schedule developed before risk analysis.
  2. The most recent schedule update approved by the team.
  3. The approved version used to measure schedule performance. Correct answer.
  4. The schedule that reflects actual progress to date.

Explanation

A schedule baseline is the approved version of the schedule against which actual performance is compared. It is usually set through formal change control and changes only when a scope or schedule change is approved. Statused versions and working drafts are not baselines.

Question 47Schedule Development

What does schedule crashing involve?

  1. Reducing scope to meet the imposed finish date.
  2. Removing dependencies to shorten the critical path.
  3. Overlapping activities that were planned in sequence.
  4. Adding resources to shorten duration, usually at higher cost. Correct answer.

Explanation

Crashing shortens critical-path activities by adding resources or working additional hours, generally increasing cost. It targets activities on the critical path because shortening noncritical work does not reduce project duration. The technique should be applied to the lowest-cost compression options first.

Question 48Schedule Development

How does resource smoothing differ from resource leveling?

  1. It uses float to level demand without extending the critical path. Correct answer.
  2. It shortens durations by adding resources.
  3. It removes all resources from noncritical activities.
  4. It may extend the project completion date.

Explanation

Resource smoothing adjusts resource demand within available float so that the critical path and project finish date are not changed. Resource leveling, by contrast, may delay activities beyond their float and can extend the project. Smoothing is therefore the preferred approach when the finish date is fixed.

Question 49Schedule Development

Activity A has a duration of 5 days. Activity B follows A with a finish-to-start relationship. Activity C follows B with a finish-to-start relationship and a 2-day lag. Durations are B = 4 days and C = 3 days. With the project starting on day 0, what is C's early finish?

  1. 12
  2. 16
  3. 14 Correct answer.
  4. 13

Explanation

The forward pass gives A an early finish of day 5. B starts on day 5, finishes on day 9, and the 2-day lag pushes C's early start to day 11. C's early finish is 11 + 3 = 14.

Question 50Schedule Development

A project's required completion is day 20. Activity D has a duration of 3 days and is followed by Activity E with a finish-to-start relationship and no lag. E's late start is day 14. What is D's late finish?

  1. 14 Correct answer.
  2. 11
  3. 17
  4. 20

Explanation

In the backward pass, D must finish no later than E's late start because the relationship is finish-to-start with no lag. D's late finish is therefore day 14. D's late start would then be day 11 after subtracting its 3-day duration.
