Planning and schedule-development checklist

Project planning foundation

You should be able to check each item confidently:

  • Explain the difference between planning the work and scheduling the work.
  • Identify the project objective, completion requirements, major deliverables, constraints, and assumptions.
  • Determine which stakeholders provide scope, logic, production, calendar, access, procurement, commissioning, or turnover information.
  • Recognize how contract requirements, governance processes, and reporting cycles influence schedule structure.
  • Define the schedule’s purpose: bid planning, baseline control, lookahead planning, recovery planning, forensic analysis, or management reporting.
  • Explain why schedule level of detail should be tailored to the decision being supported.
  • Identify when rolling-wave planning is appropriate because future work is not yet fully defined.
  • Distinguish a milestone schedule, summary schedule, detailed control schedule, and short-interval lookahead.

Scope, WBS, and activity definition

TopicExam-ready skillCommon error
WBS / work packagingBreak scope into manageable deliverables or work packages.Treating departments, cost accounts, or phases as complete schedule logic.
Activity descriptionsWrite activities with action, object, and measurable completion.Using vague labels such as “work on area” or “continue construction.”
MilestonesUse milestones for meaningful start, finish, approval, turnover, or external events.Using milestones as substitutes for real activity logic.
ResponsibilityAssign accountable parties or disciplines where useful.Leaving ownership unclear, making status unreliable.
InterfacesInclude owner, designer, vendor, subcontractor, permitting, inspection, testing, and commissioning interfaces.Modeling only direct production work and ignoring external dependencies.
Completion criteriaDefine how activity completion will be measured.Confusing partial effort with deliverable completion.

“Can you do this?” activity-definition prompts

  • Given a scope statement, create a reasonable activity list.
  • Identify activities that should be split because they are too long or cover multiple crews/areas.
  • Identify activities that should be combined because they are too detailed for control.
  • Convert deliverables into measurable activity completions.
  • Add missing predecessor and successor relationships.
  • Identify external dependencies that should not be hidden in duration estimates.
  • Explain how WBS, activity codes, cost accounts, areas, phases, and responsibilities support filtering and reporting.

CPM and network logic readiness

Logic relationships you should know

RelationshipMeaningScenario cue
Finish-to-startSuccessor starts after predecessor finishes.Sequential handoff, installation after delivery, testing after installation.
Start-to-startSuccessor starts after predecessor starts, often with lag.Overlapping work such as rough-in following framing start.
Finish-to-finishSuccessor finishes after predecessor finishes, often with lag.Closeout, testing, documentation, or parallel completion dependencies.
Start-to-finishSuccessor finishes after predecessor starts.Less common; understand it, but question whether it is appropriate.
LeadAllows overlap by accelerating successor timing.May hide risk if used instead of explicit logic.
LagWaiting period between related activities.Cure time, review period, delivery wait, or access window.
ConstraintImposed date restriction or requirement.Use carefully; constraints can override logic-driven dates.

CPM calculation readiness

You should be able to perform these without relying on scheduling software:

  • Conduct a forward pass to calculate early start and early finish.
  • Conduct a backward pass to calculate late start and late finish.
  • Determine the critical path or longest path.
  • Calculate total float and free float.
  • Explain why the critical path can change after progress, logic changes, or delays.
  • Identify near-critical paths and explain why they matter.
  • Explain the impact of multiple calendars on date calculations.
  • Detect open starts, open finishes, dangling logic, and logic gaps.
  • Explain why negative float often indicates a constraint, deadline, or required completion earlier than the logic forecast.

Use the date-counting convention given in the question. If a question gives its own convention, follow it even if your workplace uses a different one.

\[ EF = ES + D \]\[ LS = LF - D \]\[ TF = LS - ES = LF - EF \]

Where \(D\) is activity duration and \(TF\) is total float, subject to the date-counting convention used in the problem.

CPM decision checks

If the scenario says…Ask yourself…Better exam response
A path has zero or least floatIs it the current controlling path?Treat it as critical or potentially critical based on the schedule logic and constraints.
Negative float appearsIs there a deadline, imposed finish, or unrealistic constraint?Identify the driver before proposing acceleration.
A lag is very longIs the lag representing real work?Consider replacing hidden work with explicit activities.
Many activities have hard constraintsIs the schedule logic being overridden?Recommend reviewing constraints and restoring logic-driven sequencing where possible.
Progress is out of sequenceAre actuals valid? How will the schedule calculation treat remaining logic?Validate actuals, document the method, and explain forecast effect.
Critical path changed after updateDid actual progress, remaining duration, logic, calendar, or constraints change?Trace the driver rather than assuming software error.

Duration, productivity, and resource readiness

Duration estimating

Be ready to connect quantities, production rates, crew assumptions, calendars, and uncertainty.

\[ \text{Duration} = \frac{\text{Quantity of work}}{\text{Production rate per time period}} \]

Common duration-estimating prompts:

  • Calculate duration from quantity and crew production rate.
  • Adjust duration when crew size, shift length, productivity, or calendar changes.
  • Explain why production rate assumptions should be documented.
  • Identify when duration is driven by external review, fabrication, delivery, cure time, inspection, or access rather than direct labor.
  • Distinguish effort hours from elapsed duration.
  • Recognize when optimistic durations create an unrealistic critical path.

Resource loading and leveling

ConceptWhat to knowTrap
Resource loadingAssigning labor, equipment, or other resources to activities.Assuming a resource-loaded schedule is automatically feasible.
Resource availabilityLimits on crews, equipment, materials, or specialist labor.Ignoring bottleneck resources on parallel activities.
Resource levelingAdjusting activity timing to resolve over-allocation.Forgetting leveling may consume float or move completion.
Resource smoothingAdjusting resources within available float.Confusing smoothing with changing the project finish date.
Cost loadingAssigning budget or cost values to activities.Treating cost progress as identical to physical progress.
Crew logicSequencing work based on crew movement and productivity.Creating logic that looks valid but ignores real crew flow.

Resource scenario checks

  • If two critical activities require the same limited crew, can you identify the schedule conflict?
  • If resource leveling delays the finish date, can you explain why the original CPM schedule was not resource-feasible?
  • If a stakeholder asks to shorten duration by adding labor, can you identify productivity, access, safety, congestion, and diminishing-return issues?
  • If procurement delays a material, can you trace which installation, testing, commissioning, and turnover activities are affected?
  • If weather or site access limits productivity, can you separate calendar effects from production-rate effects?

Baseline, status, and schedule-control checklist

Baseline schedule readiness

Baseline topicBe ready to explain
PurposeThe baseline is the approved plan used to measure performance and evaluate change.
ReviewThe baseline should be checked for scope coverage, logic, calendars, constraints, milestones, coding, resource assumptions, and reporting needs.
ApprovalBaseline acceptance should be documented through the project’s governance process.
PreservationThe original baseline should be retained for comparison and audit trail.
ChangeApproved changes may require schedule incorporation, baseline revision, or separate variance tracking depending on governance.
TraceabilityMajor changes should be traceable to change records, assumptions, narratives, and schedule files.

Statusing and updating

You should be able to answer update-cycle questions such as “what should the scheduler do next?”

  • Establish the data date.
  • Collect actual starts and actual finishes.
  • Validate remaining duration, not just percent complete.
  • Update progress consistently across disciplines or contractors.
  • Confirm whether logic changes are actual work-sequence changes or improper forecast manipulation.
  • Recalculate the schedule after status entry.
  • Review changed critical and near-critical paths.
  • Identify variance from baseline dates and milestone commitments.
  • Document causes, impacts, and assumptions in the schedule narrative.
  • Communicate required decisions, recovery options, or risk exposure.

	    F -- Yes --> H[Analyze cause and affected paths]
	    H --> I[Prepare options: mitigation, recovery, change, or escalation]
	    I --> J[Update narrative, logs, and governance records]

Progress measurement readiness

Measurement typeUse whenWatch for
Actual start / finishActivity has clearly begun or completed.Entering planned dates as actuals without evidence.
Remaining durationForecasting time needed from the data date.Leaving remaining duration unchanged despite changed conditions.
Physical percent completeWork quantity or deliverable completion can be measured.Equating effort spent with work accomplished.
Duration percent completeTime elapsed is a reasonable proxy.Misleading when production is ahead or behind.
Units completeQuantifiable work installed, produced, tested, or accepted.Poor quantity tracking or inconsistent measurement rules.
Milestone completionDiscrete event occurred.Claiming milestone completion before acceptance criteria are met.

Variance, forecasting, and reporting readiness

Variance analysis

Be able to interpret:

  • Baseline start variance.
  • Baseline finish variance.
  • Current forecast finish variance.
  • Milestone slippage.
  • Float erosion.
  • Critical path change.
  • Delayed starts caused by predecessor slippage.
  • Extended durations caused by productivity loss.
  • Acceleration or resequencing effects.
  • Difference between local activity variance and overall project impact.

Earned value and schedule interface

If a question gives earned value data, be ready to apply basic schedule-performance concepts while remembering that earned value indicators do not replace CPM logic.

TermPlain meaningReadiness cue
Planned ValueBudgeted value of work planned by a point in time.Know what should have been earned by the status date.
Earned ValueBudgeted value of work actually accomplished.Know what was earned based on progress rules.
Schedule VarianceEV minus PV.Positive or negative value indicates ahead/behind planned value, not automatically CPM days.
Schedule Performance IndexEV divided by PV.Ratio above or below 1.0 indicates performance against planned value.
CPM forecastLogic-based forecast of finish dates.Use for path-driven schedule impact.

Reporting prompts

  • Can you write a short schedule narrative explaining what changed since the last update?
  • Can you identify the current critical path and near-critical paths?
  • Can you state whether the forecast completion changed and why?
  • Can you separate cause, effect, and recommended action?
  • Can you tailor detail for an executive summary versus a scheduler’s technical review?
  • Can you support the report with dates, float, milestones, and documented assumptions?

Change, delay, and disruption readiness

Change-impact thinking

For PSP preparation, focus on defensible schedule logic and documentation. Legal and contractual labels can vary by contract and jurisdiction, so read the scenario carefully.

TopicBe ready to do this
Change identificationRecognize scope changes, design changes, late approvals, differing conditions, access restrictions, procurement delays, and owner/contractor interface issues.
Impact tracingFollow the impact through affected activities, paths, milestones, resources, and completion dates.
Contemporaneous recordsIdentify useful records: schedules, updates, daily reports, correspondence, RFIs, submittals, change logs, meeting minutes, progress photos, and production records.
Fragnet conceptUnderstand a small network of added or changed activities used to model an impact.
Time impact analysis conceptUnderstand prospective insertion of a change into an appropriate schedule update to evaluate forecast impact.
As-planned vs. as-built thinkingCompare planned sequence and actual performance carefully before concluding delay impact.
Concurrency awarenessRecognize that multiple delays can affect the same period or different paths.
Mitigation and recoveryEvaluate resequencing, additional resources, overtime, shift work, procurement alternatives, or scope prioritization.

Delay scenario decision points

Scenario cueWhat to check firstLikely sound action
A change is issued before baseline approvalIs the change part of the original scope or new scope?Clarify scope basis and incorporate approved planning assumptions.
A change is issued after baseline approvalIs there a change-control process?Model the change, document assumptions, and preserve baseline comparison.
A stakeholder claims a delay affected completionDid it affect the controlling or near-controlling path?Trace through CPM logic and contemporaneous schedule updates.
A noncritical activity is delayedDid it consume float or become critical later?Analyze float use and downstream path effects.
Two delays occur in the same periodAre they on the same path, different paths, or both controlling?Avoid simplistic conclusions; analyze timing, paths, and records.
Management asks to “fix” the schedule datesAre dates logic-driven and documented?Maintain schedule integrity and clearly document approved changes.
Acceleration is proposedWhat is the cost, feasibility, risk, and effect on critical path?Compare options and explain tradeoffs.

Risk, uncertainty, and contingency readiness

Schedule risk concepts

You should be able to explain:

  • Difference between a risk event and estimating uncertainty.
  • Why deterministic dates may not capture schedule confidence.
  • How uncertainty in critical and near-critical activities affects completion.
  • Why risk mitigation should be tied to specific activities or paths.
  • How contingency differs from hidden padding.
  • Why risk responses may create secondary risks.
  • How schedule risk information should be communicated without overstating precision.

Risk checklist

Risk areaExam-style cuePrepared response
Weather or seasonal limitsCalendar and productivity effects.Model non-work periods or reduced production realistically.
Long-lead procurementDelivery controls installation or commissioning.Include procurement, fabrication, delivery, inspection, and release milestones.
Design or approval delaysWork cannot proceed without information.Model submittals, reviews, RFIs, and approvals as schedule logic where appropriate.
Resource shortagesPlanned parallel work is not feasible.Test crew and equipment availability, then level or resequence.
Access constraintsWork area not available.Include turnover, permits, outages, or access milestones.
Commissioning riskLate testing affects turnover.Plan testing, punch list, approvals, and handover explicitly.
Interface riskMultiple parties share dependencies.Use interface milestones and clear responsibility.

Schedule quality and validation checklist

Before treating a schedule as reliable, you should be able to review it for technical quality.

Technical schedule checks

  • Are all required scope areas represented?
  • Are activities clearly defined and measurable?
  • Does each activity have appropriate predecessors and successors?
  • Are open starts or open finishes justified?
  • Are lags used appropriately and not hiding real work?
  • Are leads used sparingly and logically?
  • Are constraints necessary, documented, and not masking poor logic?
  • Are calendars assigned correctly?
  • Are durations reasonable for the work and control level?
  • Are unusually long activities reviewed?
  • Are milestones meaningful and traceable to requirements?
  • Are critical and near-critical paths plausible?
  • Are negative float and missed deadlines explained?
  • Are resources and production assumptions feasible?
  • Are cost loading and progress rules aligned with reporting needs?
  • Is the data date correct in updates?
  • Are actual dates supported by records?
  • Are baseline and current schedules clearly distinguished?
  • Are schedule narratives consistent with the calculated schedule?

Scenario judgment checklist

The PSP exam is likely to reward applied judgment, not isolated memorization. Practice choosing the best next action.

“What should the scheduler do next?” prompts

SituationStrong next action
Actual progress differs from the planned sequence.Validate actuals, update remaining logic consistently, document out-of-sequence treatment, and review forecast impact.
A milestone is forecast late.Identify the driving path, quantify variance, review mitigation options, and communicate impact.
A stakeholder disputes the current critical path.Trace logic, calendars, constraints, and recent updates; use evidence rather than opinion.
A new constraint creates negative float.Determine why the constraint was added, whether it is valid, and how it affects the forecast.
A schedule has many activities with no successors.Review for open ends and missing logic before relying on critical path results.
A progress report shows high percent complete but late finish forecast.Check remaining duration, critical path, incomplete deliverables, and progress measurement method.
A proposed recovery plan adds crews.Test resource availability, productivity limits, access constraints, and actual effect on critical activities.
A change affects a noncritical path.Determine available float and whether the path could become critical.
A procurement delay is discovered.Identify downstream installation, testing, commissioning, and turnover effects.
A team wants to rebaseline to remove variance.Confirm governance approval, change basis, audit trail, and reporting purpose.

Common weak areas and traps

Use this list for final review. If any item feels uncomfortable, drill it before moving to full-length practice.

Weak areaWhy it causes errorsHow to fix it
Planning vs. schedulingCandidates jump into dates before understanding scope and strategy.Start every scenario by identifying purpose, deliverables, constraints, and stakeholders.
Total float vs. free floatFloat terms are often confused.Practice small networks until you can explain who can use the float and what downstream effect occurs.
Critical path vs. shortest visible bar sequenceGantt charts can mislead.Trace logic and calculate path duration or float.
Constraints vs. logicImposed dates can hide the true forecast.Ask whether dates are calculated by relationships or forced by constraints.
Percent complete misusePercent complete does not always predict finish.Focus on remaining duration and completion criteria.
Resource feasibilityCPM may assume unlimited resources.Check resource conflicts and leveling effects.
Hidden work in lagsLong lags can conceal real activities.Convert significant waiting, review, cure, fabrication, or delivery into explicit activities when appropriate.
Multiple calendarsCalendar differences change path timing.Note which calendar applies to each activity or relationship.
Baseline confusionCandidates mix original plan, current update, and revised baseline.Label schedule versions and know the purpose of each.
Out-of-sequence progressSoftware settings can change forecasts.Understand the logic issue and document treatment.
Near-critical pathsFocusing only on one critical path misses emerging risk.Review paths with low float and high uncertainty.
Negative floatCandidates treat it as ordinary float.Identify the imposed date or missed deadline causing it.
Cost progress vs. schedule progressEarned value may not show CPM path impact.Use EV for performance indicators and CPM for logic-driven finish forecasts.
Delay conclusions without recordsClaims analysis depends on timing and evidence.Preserve baseline, updates, actual records, and change documentation.
Over-acceleration assumptionMore resources do not always shorten duration.Consider access, productivity, congestion, sequencing, safety, and cost.
