Scenario 1
Steel erection is on the current longest path. Its remaining duration increases by five workdays, with no recovery, calendar change, or path shift.
What is the defensible scheduling conclusion?
- The contractor automatically receives a five-day extension of time.
- Recalculate the network; completion is forecast to move five workdays, while entitlement remains a separate determination.
- Ignore the change because total float belongs exclusively to one party.
Read the explanation
Recalculate the network; completion is forecast to move five workdays, while entitlement remains a separate determination.
CPM quantifies the forecast effect of the duration change. It does not decide contractual entitlement, ownership of float, responsibility, or compensability.
Scenario 2
Two activities both display ten days of remaining duration, but one uses a five-day calendar and the other uses a six-day calendar with longer shifts.
How should a professional compare them?
- Treat them as the same amount of working time because both display ten days.
- Convert both to calendar days and ignore the assigned activity calendars.
- Review the assigned calendars, work hours, and conversion settings before comparing duration or float.
Read the explanation
Review the assigned calendars, work hours, and conversion settings before comparing duration or float.
Displayed days depend on calendar work periods and administrative conversion settings. Equal displayed values can represent different working-time quantities.
Scenario 3
An original baseline starts owner-furnished equipment at installation and omits design release, manufacture, delivery, and inspection interfaces.
What is the correct baseline treatment?
- Represent the material owner-vendor chain and connect it dynamically to installation, even though another party performs the work.
- Exclude the chain because a contractor schedule should contain only contractor-controlled work.
- Add a narrative footnote but leave the enabling work outside the network.
Read the explanation
Represent the material owner-vendor chain and connect it dynamically to installation, even though another party performs the work.
A comprehensive schedule represents material interfaces and responsibility boundaries so their timing can affect downstream work and completion.
Scenario 4
Two months after baseline acceptance, the team proposes overwriting the approved baseline with the current forecast so the variance report returns to zero.
What control should the project apply?
- Overwrite it because the current plan is always the most relevant comparison.
- Preserve the accepted baseline and process any authorized revision through documented change control and reconciliation.
- Delete all baseline assignments and report only current dates.
Read the explanation
Preserve the accepted baseline and process any authorized revision through documented change control and reconciliation.
The approved baseline preserves the performance yardstick. Authorized scope or plan changes require a controlled record, not silent removal of historical variance.
Scenario 5
A May update has a 31 May data date, but an activity is recorded with an actual finish of 3 June.
What should the reviewer require?
- Keep the future actual because the work finished before the file was submitted.
- Move the data date to 3 June without reconciling the rest of the status.
- Reconcile the cutoff: correct the actual or place it in the next status period, with the schedule and evidence using one boundary.
Read the explanation
Reconcile the cutoff: correct the actual or place it in the next status period, with the schedule and evidence using one boundary.
Actual dates beyond the data date conflict with the stated status boundary. The cutoff, native file, and supporting progress record must reconcile.
Scenario 6
An activity is reported 60% complete and its remaining duration is cut from twenty days to six, with no crew, quantity, productivity, or recovery evidence.
What is the strongest review response?
- Accept the reduction because percent complete controls remaining duration.
- Treat remaining duration as a forecast assumption and require a measurable production or recovery basis.
- Restore the original duration automatically without asking how the remaining work changed.
Read the explanation
Treat remaining duration as a forecast assumption and require a measurable production or recovery basis.
Percent complete does not independently prove the remaining time. The forecast should reflect remaining quantities, means, resources, productivity, and field conditions.
Scenario 7
A comparison file changes P6 out-of-sequence handling from retained logic to progress override while also adding a change-event fragnet.
How should the analyst protect the comparison?
- Use identical scheduling options, or isolate and disclose the effect of the option change before attributing the result to the fragnet.
- Use whichever option creates the largest completion movement.
- Ignore scheduling options because only activity logic affects the result.
Read the explanation
Use identical scheduling options, or isolate and disclose the effect of the option change before attributing the result to the fragnet.
A valid comparison controls unrelated variables. P6 scheduling options can change calculated dates and must remain consistent or be separately analyzed.
Scenario 8
A scheduler is preparing to transmit the monthly native XER as the controlled record.
Which exchange control is strongest?
- Rename the file clearly and assume export success means the content is intact.
- Send only a PDF because a native-file comparison is unnecessary.
- Preserve the source, import the XER into a controlled temporary project, and compare counts, calendars, logic, dates, settings, and logs.
Read the explanation
Preserve the source, import the XER into a controlled temporary project, and compare counts, calendars, logic, dates, settings, and logs.
A round-trip verification tests the exchanged artifact rather than assuming the export retained every required schedule element.
Scenario 9
A schedule-quality screen flags six activities longer than the project’s thirty-day review threshold. Each has a quantity, crew, rate, and monthly measurement rule.
How should the reviewer classify the flag?
- Automatic failure because every threshold exceedance is a defect.
- A screening result that requires investigation; the documented basis may support the durations.
- Irrelevant because activity duration never affects schedule credibility.
Read the explanation
A screening result that requires investigation; the documented basis may support the durations.
Quality thresholds focus professional review. They do not replace contract requirements, the planning basis, materiality, or expert judgment.
Scenario 10
The narrative says the critical path is unchanged, while the recalculated native file shows procurement and commissioning have replaced enclosure and interiors as the longest path.
What should happen before disposition?
- Use the narrative because it is the signed management document.
- Use whichever path has the least total float without checking settings.
- Reconcile the narrative with the native calculation, settings, and model changes that caused the path movement.
Read the explanation
Reconcile the narrative with the native calculation, settings, and model changes that caused the path movement.
The narrative must explain the schedule that was actually calculated. A material path change affects management focus and requires evidence-based explanation.
Scenario 11
A prospective TIA for a 9 September directive starts from a revised update statused through 30 September rather than the accepted update immediately preceding the event.
What is the central technical concern?
- The later source may include hindsight and changed status, so the analysis must justify the information date or use the appropriate contemporaneous pre-impact schedule.
- A TIA should always use the latest available schedule regardless of the event date.
- The source schedule is irrelevant if the fragnet durations are supported.
Read the explanation
The later source may include hindsight and changed status, so the analysis must justify the information date or use the appropriate contemporaneous pre-impact schedule.
Method, information date, source schedule, and contract procedure must align. Later status can contaminate a prospective comparison with knowledge unavailable at the event date.
Scenario 12
Owner-directed redesign and contractor-caused procurement delay overlap in time, but the submittal labels the entire period owner delay without path analysis.
What is the correct professional sequence?
- Split the days evenly between the parties.
- Analyze timing, paths, causation, and available records first; then apply the governing contract and legal framework to entitlement.
- Subtract the contractor delay from the owner delay without testing whether either controlled completion.
Read the explanation
Analyze timing, paths, causation, and available records first; then apply the governing contract and legal framework to entitlement.
Calendar overlap alone does not resolve concurrency. Technical schedule analysis and contractual or legal conclusions are related but distinct steps.
Scenario 13
A team proposes Monte Carlo simulation on a schedule with open ends, unexplained constraints, and a longest path that does not reach the contractual finish.
What should happen first?
- Increase the number of simulation iterations to compensate for the model defects.
- Validate and correct the deterministic network before assigning uncertainty and interpreting confidence dates.
- Use only the P50 date because it is less sensitive to logic quality.
Read the explanation
Validate and correct the deterministic network before assigning uncertainty and interpreting confidence dates.
Simulation cannot repair an incomplete or distorted CPM model. The deterministic schedule must be credible before uncertainty results can support decisions.
Scenario 14
An executive dashboard reports a schedule performance index of 0.90 and states that the project is exactly ten percent late.
What correction is needed?
- Convert 0.90 directly into calendar days using the contract duration.
- Report the project ten percent ahead because any value below one is favorable.
- Treat SPI as an earned-value efficiency signal and investigate CPM dates, paths, milestones, and forecast variance separately.
Read the explanation
Treat SPI as an earned-value efficiency signal and investigate CPM dates, paths, milestones, and forecast variance separately.
SPI compares earned and planned value. It does not directly state calendar-time lateness, critical-path delay, or forecast completion movement.
