Basic Primavera P6 Interview Questions & Answers (Q1–Q15)

These questions are typically asked for Primavera P6 fresher interview questions or junior scheduler roles. They cover core concepts every P6 user must know.

Q1. What is Primavera P6 and why is it used in construction?

Answer: Oracle Primavera P6 is an enterprise project portfolio management (PPM) software used for planning, scheduling, managing, and controlling large-scale projects. It is widely used in construction, engineering, oil & gas, and infrastructure sectors because it can handle thousands of activities, multiple projects, complex resource pools, and multi-level reporting — capabilities that simpler tools like MS Project cannot match at scale.

Q2. What is the difference between Primavera P6 Professional and P6 EPPM?

Answer: P6 Professional is a standalone, client-server desktop application used by individual planners. P6 EPPM (Enterprise Project Portfolio Management) is a web-based, multi-user platform that supports organisation-wide access, role-based permissions, and centralized database management. EPPM is preferred by large organisations that need multiple departments accessing a single source of truth simultaneously.

Q3. What is EPS in Primavera P6?

Answer: EPS (Enterprise Project Structure) is the hierarchical framework that organises all projects within an organisation in Primavera P6. It mirrors the company’s business structure — for example: Organisation → Division → Programme → Project. EPS allows managers to roll up data across multiple projects for portfolio-level reporting and control. Correct EPS setup is critical to maintaining data integrity across large project portfolios.

Q4. What is OBS in Primavera P6?

Answer: OBS (Organisational Breakdown Structure) defines who is responsible for what within an organisation. In Primavera P6, OBS is used to assign access rights and responsibilities to users at different levels of the EPS. It controls what a user can see and edit within the system, ensuring data security and role-based governance.

Q5. What is WBS in Primavera P6?

Answer: WBS (Work Breakdown Structure) is a hierarchical decomposition of the total scope of work into manageable deliverables or work packages within a project. In Primavera P6, every activity must belong to a WBS element. The WBS provides the structural framework for organising, planning, and reporting on project work. It is one of the most common topics in Primavera P6 WBS interview questions.

Q6. What are the types of Activity Types available in Primavera P6?

Answer: Primavera P6 offers six activity types:

Task Dependent – Duration depends on the task; resources are secondary.
Resource Dependent – Duration depends on resource availability.
Level of Effort (LOE) – Duration is driven by its predecessor/successor span.
Start Milestone – A zero-duration activity marking the start of a phase.
Finish Milestone – A zero-duration activity marking the end of a phase.
WBS Summary – A summary rollup of all activities within a WBS node.

Q7. What is the difference between a Start Milestone and a Finish Milestone?

Answer: Both are zero-duration activities used to mark key events in a schedule. A Start Milestone signifies the beginning of a significant event or phase, while a Finish Milestone marks the completion or delivery of a significant deliverable. Milestones are commonly used for contractual dates, handover points, and programme gates.

Q8. What are the four relationship types in Primavera P6?

Answer:

Finish-to-Start (FS) – Successor starts after predecessor finishes. Most common.
Start-to-Start (SS) – Successor starts when predecessor starts.
Finish-to-Finish (FF) – Successor finishes when predecessor finishes.
Start-to-Finish (SF) – Successor finishes when predecessor starts. Rare.

Q9. What is Lag and Lead in Primavera P6?

Answer: Lag is a delay added between two linked activities (e.g., concrete needs 7 days to cure before formwork can be stripped — a 7-day FS lag). Lead (expressed as negative lag) allows an activity to start before its predecessor is complete, overlapping activities to compress the schedule. Excessive use of lead time is a scheduling risk as it can create unrealistic plans.

Q10. What is the Critical Path Method (CPM) and how is it calculated in P6?

Answer: The Critical Path Method (CPM) identifies the longest path of dependent activities through a project network, determining the minimum project duration. In P6, after scheduling the project, the critical path is identified through a Forward Pass (calculating Early Start and Early Finish) and a Backward Pass (calculating Late Start and Late Finish). Activities with zero total float lie on the critical path. P6 highlights these in red by default. This is one of the most heavily tested topics in Primavera P6 critical path (CPM) interview questions.

Q11. What is Total Float and Free Float?

Answer:

Total Float (TF) = Late Start − Early Start (or Late Finish − Early Finish). It is the amount of time an activity can be delayed without delaying the project end date.
Free Float (FF) is the amount of time an activity can be delayed without affecting the early start of any immediate successor activity.

This is one of the most asked Primavera P6 total float vs free float concepts in scheduling interviews. An activity can have positive Total Float but zero Free Float if its delay would still impact a successor, even if the project end date is unaffected.

Q12. What is Negative Float in P6 and what does it indicate?

Answer: Negative float (also called negative slack) occurs when an activity’s Late Finish is earlier than its Early Finish — meaning the activity would need to finish before it can even begin based on the current schedule logic. It is typically caused by imposed date constraints being more restrictive than the network logic allows. Negative float is a red flag indicating the project is behind its target finish date and corrective action is required.

Q13. What is a Baseline in Primavera P6?

Answer: A baseline is a saved snapshot of the project schedule at a specific point in time — typically the approved project plan at contract award or project kickoff. In P6, you can assign up to three baselines to a project: the Project Baseline (used for variance reporting) and two User Baselines. Baselines are central to performance tracking, earned value analysis, and delay analysis.

Q14. How many baselines can be created in Primavera P6?

Answer: In Primavera P6, you can create an unlimited number of baseline copies for a project. However, only three baselines can be assigned simultaneously for comparison and reporting: one Project Baseline and two User Baselines. The Project Baseline is what drives earned value and schedule variance calculations.

Q15. What is the difference between Activity Codes and User-Defined Fields (UDFs)?

Answer: Activity Codes are categorical values used to classify, group, filter, and sort activities (e.g., Phase, Area, Responsibility, Discipline). They are stored globally or at project level and are ideal for grouping schedules. User-Defined Fields (UDFs) are custom data fields added to activities, projects, or resources to capture additional information not available in standard P6 fields — such as contract reference numbers, approval status, or custom cost fields. UDFs offer more flexibility but are not used for schedule grouping the same way activity codes are. This distinction is a classic Primavera P6 activity codes vs UDF question.

Intermediate Primavera P6 Interview Questions & Answers (Q16–Q35)

These questions are suited for Primavera P6 planning engineer interview questions and roles requiring 2–5 years of scheduling experience.

Q16. What is Resource Leveling in Primavera P6?

Answer: Resource leveling is the process of adjusting activity start and finish dates to resolve resource over-allocations — ensuring no resource is assigned more hours than they are available in a given period. In P6, resource leveling can extend the project duration (by pushing non-critical activities) or it can be constrained to a specific finish date. The Resource Leveling tool in P6 prioritises activities based on user-defined leveling priority, float, and relationship logic. This is a critical topic in Primavera P6 resource leveling interview questions.

Q17. What is the difference between Resource Leveling and Resource Smoothing?

Answer: Resource leveling resolves over-allocation by adjusting activity dates, potentially extending project duration. Resource smoothing (sometimes called resource-constrained scheduling) adjusts only within the available float of activities — keeping the project end date intact but reducing resource spikes. P6 primarily performs leveling, though careful manipulation of activity float and priority settings can approximate smoothing outcomes.

Q18. Explain Earned Value Management (EVM) in the context of P6.

Answer: Earned Value Management (EVM) integrates scope, schedule, and cost to provide objective performance metrics. The three core EVM values in P6 are:

PV (Planned Value / BCWS) – Budgeted cost of work scheduled.
EV (Earned Value / BCWP) – Budgeted cost of work performed (based on % complete).
AC (Actual Cost / ACWP) – Actual cost incurred for work performed.

Key performance indicators derived include: SPI (Schedule Performance Index) = EV/PV and CPI (Cost Performance Index) = EV/AC. P6 calculates EVM automatically when a financial baseline is assigned and actual costs are updated. This is a core area of Primavera P6 earned value management (EVM) interview questions.

Q19. What are the types of Constraints in Primavera P6?

Answer: P6 supports the following constraint types:

Start On – Forces the activity to start on a specific date.
Start On or Before – Activity must start on or before the specified date.
Start On or After – Activity must start on or after the specified date.
Finish On – Forces the activity to finish on a specific date.
Finish On or Before – Activity must finish on or before the specified date.
Finish On or After – Activity must finish on or after the specified date.
Mandatory Start – Hard constraint; overrides all schedule logic for the start date.
Mandatory Finish – Hard constraint; overrides all schedule logic for the finish date.
As Late As Possible – Schedules the activity as late as possible without impacting successors.

Overuse of Mandatory constraints is a common scheduling malpractice — they suppress float calculations and mask real schedule issues, making Primavera P6 constraints (mandatory start/finish) questions a favourite of experienced interviewers.

Q20. What is the difference between Remaining Duration and Original Duration?

Answer: Original Duration (OD) is the planned duration of an activity as set at the time of baseline. Remaining Duration (RD) is the estimated time still needed to complete the activity from the data date. As work progresses and actual hours are logged, remaining duration should be updated by the planner based on field progress — not automatically calculated. The relationship between OD, RD, and percentage complete drives the schedule performance metrics.

Q21. What are the different % Complete types in Primavera P6?

Answer: P6 offers three % complete types:

Duration % Complete – Calculated from remaining vs original duration.
Units % Complete – Based on actual resource units used vs total budgeted units.
Physical % Complete – Manually entered by the planner based on actual field progress measurement. This is the most reliable for construction projects as it reflects real-world progress independent of time elapsed.

Q22. What is a Data Date in Primavera P6?

Answer: The Data Date (also called Status Date or Time Now) is the point in time that divides completed work from remaining work. It is the date up to which actual progress has been recorded. When P6 reschedules the project, it uses the data date as the starting point for calculating remaining work. Keeping the data date accurate is essential for meaningful schedule updates and delay analysis.

Q23. How do you perform a Schedule Update in Primavera P6?

Answer: A typical schedule update process in P6 involves:

Setting the correct Data Date.
Updating Actual Start and Actual Finish dates for completed activities.
Entering Remaining Duration for in-progress activities.
Updating Physical % Complete where applicable.
Adding or modifying actual resource units/costs.
Running Schedule (F9) to recalculate the network.
Reviewing the Critical Path and float values for changes.
Comparing to the baseline and reporting variances.

Q24. What is the difference between Retained Logic, Progress Override, and Actual Dates scheduling modes?

Answer:

Retained Logic – Out-of-sequence activities wait for their predecessors to complete before their remaining duration is scheduled. This preserves the original network logic. Recommended for most construction projects.
Progress Override – Ignores predecessor logic for activities already started, scheduling remaining duration from the data date. Useful when field reality deviates from planned sequence.
Actual Dates – Uses actual start dates for in-progress activities to calculate remaining work, without reference to predecessor relationships.

Most contracts and scheduling specifications (e.g., DCMA 14-Point Assessment) recommend Retained Logic.

Q25. What is the DCMA 14-Point Schedule Assessment?

Answer: The DCMA (Defense Contract Management Agency) 14-Point Assessment is a schedule quality checklist used to evaluate Integrated Master Schedules (IMS) on US government projects. It checks metrics such as missing logic, negative float, high float, hard constraints, out-of-sequence activities, invalid dates, resources, and more. While it originated in the defence sector, it is widely used as a scheduling best-practice benchmark in commercial construction and infrastructure projects globally.

Q26. How do you set up a Resource in Primavera P6?

Answer: Resources in P6 are created under the Enterprise > Resources menu. Key setup parameters include: Resource Type (Labour, Non-Labour, Material), Resource Availability (calendar and units/time), Default Units/Time (e.g., 8 hours per day), Price/Unit, and whether the resource uses shifts. Once set up globally, resources are assigned to activities in the project schedule. Resource hierarchies can be set up to mirror organisational charts, supporting roll-up reporting.

Q27. What is Global Change in Primavera P6 and how is it used?

Answer: Global Change is a powerful batch-editing tool in P6 that allows planners to make mass updates to activity data based on defined criteria. It can modify fields like activity type, calendar assignment, duration, codes, and custom fields across hundreds of activities simultaneously. For example, a Global Change can be set up to: “If Activity Code = Civil, then set Calendar = Civil Calendar.” While powerful, Global Change should be used carefully as it can overwrite data across the entire project if criteria are not set precisely. This is a common Primavera P6 Global Change question in senior scheduler interviews.

Q28. What is the difference between P6 and MS Project?

Answer: This is one of the most common Primavera P6 vs MS Project interview questions. Key differences:

Scale – P6 handles enterprise-level, multi-project environments; MS Project is suited for smaller, single-project use.
Database – P6 uses Oracle or SQL Server; MS Project uses a proprietary file format (.mpp).
Multi-user – P6 EPPM supports concurrent multi-user access; MS Project requires additional tools for collaboration.
EVM – P6 has built-in EVM with financial period data; MS Project’s EVM is more limited.
Resource Management – P6 offers more sophisticated resource leveling and role/resource hierarchy.
Cost – P6 is significantly more expensive; MS Project has lower licensing costs.
Learning Curve – P6 has a steeper learning curve but offers greater capability.

Q29. What is a Calendar in Primavera P6 and what types exist?

Answer: Calendars in P6 define the working and non-working days and hours for a project, activity, or resource. There are three types:

Global Calendars – Available across all projects in the database.
Project Calendars – Specific to a single project.
Resource Calendars – Assigned to specific resources to reflect their unique working patterns (e.g., night shift, part-time).

A project typically has a default project calendar, but individual activities or resources can use different calendars, which affects duration and float calculations.

Q30. What is the purpose of the Project Notebook in Primavera P6?

Answer: The Project Notebook (also accessible at WBS and Activity level) is a free-text documentation area within P6 that allows planners to add narrative, assumptions, methodologies, and commentary to the schedule. It is useful for recording why certain decisions were made, communicating scope assumptions, and satisfying contractual requirements to submit a Basis of Schedule document alongside the programme.

Q31. Explain the concept of Schedule Compression techniques used in P6.

Answer: When a project is behind schedule, planners use two primary compression techniques:

Crashing – Adding additional resources to critical path activities to shorten their duration, at an increased cost.
Fast Tracking – Executing activities in parallel that were originally planned sequentially, increasing risk but compressing the schedule without necessarily increasing cost.

Both techniques are modelled in P6 by adjusting logic (leads), adding resource assignments, or changing durations on critical path activities.

Q32. What is Hammock Activity in Primavera P6?

Answer: A Hammock activity (known as a Level of Effort (LOE) activity in P6) is a summary-type activity whose duration is determined by its predecessor’s start and its successor’s finish — it “hangs” between two points in the schedule. Hammocks are commonly used to represent overhead activities, management effort, or support tasks that span a portion of the project, such as “Project Management” or “Engineering Support.” Their duration automatically adjusts as the underlying programme changes.

Q33. What is Schedule Float Management and why is it important?

Answer: Float management is the practice of monitoring and controlling the consumption of total float across a project schedule. Contractually, float ownership can be disputed — some contracts specify that float belongs to the project (shared), while others claim it for the contractor or employer. In practice, planners must track float consumption on near-critical paths (e.g., activities with <10 days float) and alert the project team before those paths become critical. Proactive float management is a key differentiator between a reactive scheduler and a strategic planning engineer.

Q34. What is Look-Ahead Schedule and how is it created from P6?

Answer: A Look-Ahead Schedule (typically 3-week or 6-week) is a short-interval schedule extracted from the master P6 programme to guide day-to-day site operations. In P6, look-ahead schedules are created using filters on the Data Date and activity start dates (e.g., activities starting within the next 21 days), then exported to Excel or printed as a Short-Term Plan. They show upcoming activities, resource assignments, and predecessor dependencies for the immediate construction period.

Q35. What is the Scheduling Specification (Schedule Spec) and why does it matter in P6 projects?

Answer: A Scheduling Specification is a contractual document that defines the requirements for the project schedule — including software (P6 version), WBS depth, activity coding, baseline procedures, update frequency, float management rules, and reporting formats. In P6 projects on major infrastructure or government contracts, failure to comply with the schedule specification can lead to schedule rejection or contractual non-compliance. A good planning engineer reads and implements the schedule spec from project inception.

Advanced Primavera P6 Interview Questions & Answers (Q36–Q50)

These questions target senior planning engineers, project controls managers, and lead schedulers — reflecting the depth expected from those with 5+ years of P6 experience.

Q36. How do you perform Delay Analysis using Primavera P6?

Answer: Delay analysis in P6 typically follows one of several recognised methodologies:

As-Planned vs As-Built (AP vs AB) – Compares the original baseline to the actual progress schedule.
Impacted As-Planned (IAP) – Inserts delay events into the baseline and measures impact.
Collapsed As-Built (CAB) – Removes delay events from the as-built schedule to show what would have happened.
Time Impact Analysis (TIA) – Inserts delay events into the schedule at the time they occurred, measuring their impact on the critical path at that point in time. This is the most widely accepted method in UK and UAE construction contracts.

P6’s baseline comparison, float analysis, and scheduling modes (Retained Logic) are all used in forensic delay analysis.

Q37. What are Activity Step Weights and how are they used in P6?

Answer: Activity Steps are sub-tasks within an activity, each assigned a weight (percentage). When steps are marked complete, P6 automatically calculates the Physical % Complete for the activity based on the step weights. For example, “Pour Concrete” might have steps: Prepare Formwork (30%), Pour (50%), Strip (20%). As each step is checked off, P6 updates the Physical % Complete proportionally. This is especially useful for accurately tracking progress on complex construction activities with distinct sequential phases.

Q38. What is the difference between Top-Down Budgeting and Bottom-Up Budgeting in P6?

Answer: In P6’s cost management framework, Top-Down Budgeting allocates a total project budget at the EPS or WBS level first, then distributes it downward to activities. Bottom-Up Budgeting starts from individual activity resource assignments, which roll up to WBS and then project level. Most rigorous project controls environments use bottom-up budgeting tied to the resource-loaded schedule to create the Performance Measurement Baseline (PMB) for EVM reporting.

Q39. How do you manage Out-of-Sequence Progress in Primavera P6?

Answer: Out-of-sequence progress occurs when an activity starts before its predecessor is complete — contrary to the planned logic. In P6, this is managed by choosing the appropriate scheduling option:

Retained Logic (preferred): The remaining duration of the out-of-sequence activity is pushed to after the predecessor finishes. This maintains the integrity of the network logic.
Progress Override: The remaining duration is scheduled from the data date, ignoring incomplete predecessors.

The correct choice depends on the contract specification. Planners must document out-of-sequence activities and assess whether they represent actual changes in construction methodology or simply data entry errors.

Q40. Explain the concept of Risk Registers and Schedule Risk Analysis (SRA) in relation to P6.

Answer: Schedule Risk Analysis (SRA) assesses the probability of achieving planned dates by modelling uncertainty in activity durations and identifying risk drivers. While P6 itself does not natively perform Monte Carlo simulation, it integrates with tools like Oracle Primavera Risk Analysis (formerly Pertmaster) and Safran Risk. The process involves: exporting the P6 schedule, defining duration uncertainty (optimistic/most likely/pessimistic), assigning risk events, running simulations, and determining the probability of achieving the project completion date. The results inform contingency setting and risk response planning.

Q41. What is a Resource Curve in Primavera P6 and when would you use it?

Answer: A Resource Curve (or spread curve) in P6 distributes resource usage across an activity according to a defined pattern rather than uniformly. For example, a Bell curve front-loads effort in the middle of an activity, while a Front-Loaded curve concentrates effort at the start. Resource curves are used when the work on an activity is known to have a non-linear distribution — such as an engineering activity where effort peaks midway through or a commissioning activity that ramps up toward the end. They produce more accurate S-curves and resource histograms.

Q42. What is the Performance Measurement Baseline (PMB) and how is it set up in P6?

Answer: The Performance Measurement Baseline (PMB) is the approved, integrated scope-schedule-cost plan against which project performance is measured for EVM purposes. In P6, the PMB is established by:

Creating a resource- and cost-loaded schedule.
Assigning budgeted costs to each activity through resource assignments.
Saving the baseline and assigning it as the Project Baseline.
Enabling Stored Period Performance to track actual costs by financial period.

The PMB in P6 feeds directly into CPI and SPI calculations, forming the backbone of project controls reporting.

Q43. How would you set up a programme for a Design-Build project in P6?

Answer: A Design-Build programme in P6 requires careful integration of design and construction phases. The approach includes:

Structuring the WBS to reflect design packages that feed construction areas.
Using SS and FF relationships with lags to model design-construction overlaps (fast-track).
Identifying Interface milestones between design deliverables and construction starts (e.g., IFC Drawing Issue dates as logic ties).
Using Activity Codes to distinguish Design, Procurement, and Construction activities.
Modelling a Procurement schedule within the same P6 project to track long-lead items.

Q44. What is the Longest Path and how does it differ from the Critical Path in P6?

Answer: The Critical Path in P6 is defined by activities with zero total float (or the most negative float). The Longest Path is the longest sequence of activities from project start to finish, regardless of constraints or calendars — it is the absolute longest chain in the network. In projects with many constraints or open-ended activities, the Longest Path and Critical Path can differ. P6 has a specific “Longest Path” filter in the Activity Filter options that is often more reliable than the float-based critical path for identifying the true driving sequence, particularly in schedules with mandatory constraints that artificially suppress float on non-critical paths.

Q45. How do you handle Multi-Project Scheduling in Primavera P6?

Answer: P6 is built for multi-project management through its EPS hierarchy. Key practices include:

Organising projects under appropriate EPS nodes.
Using Interproject Relationships (cross-project logic ties) to link dependent activities across projects.
Applying a Global Resource Pool so resource allocation is visible across all projects simultaneously.
Running Level All Projects in resource leveling to resolve conflicts across the portfolio.
Using Project Codes and reporting at EPS level to roll up S-curves and earned value across the programme.

Q46. What is a “Fragnets” or Logic Fragment and how is it used in delay analysis?

Answer: A Fragnet (Fragment Network) is a mini-schedule network representing a specific delay event or scope change. In Time Impact Analysis (TIA), a fragnet is created to represent the delay event (e.g., a design change, site access restriction, or Force Majeure event) and then inserted into the contemporaneous schedule at the time the event occurred. The schedule is then recalculated to measure the impact on the critical path. Fragnets are used to substantiate Extension of Time (EOT) claims under construction contracts.

Q47. How do you validate the quality of a P6 schedule before submission?

Answer: Schedule quality validation (also called schedule health check) involves checking:

No activities missing logic (open ends) — except the first and last milestones.
No excessive lags or leads on relationships.
No hard constraints (Mandatory) except where contractually required.
Negative float activities investigated and resolved.
All activities have resources assigned (for resource-loaded schedules).
Activity durations within acceptable range (not too long or too short).
Calendar assignments verified.
Baseline exists and is assigned.
Total float distribution is reasonable (not all activities are critical).
P6 schedule passes the DCMA 14-Point Assessment thresholds.

Q48. What is Primavera P6 EPPM integration with Oracle Unifier or Primavera Gateway?

Answer: Oracle Primavera Gateway is a middleware integration platform that connects P6 EPPM with other Oracle products like Oracle Unifier (contract and cost management), Oracle ERP Cloud, and Primavera Contracts Management. It enables bi-directional data exchange — schedule data from P6 can populate cost control workflows in Unifier, while change orders in Unifier can trigger schedule update notifications in P6. This integration is commonly deployed on large infrastructure programmes using full Oracle project controls ecosystems (e.g., major rail, airport, or water infrastructure projects).

Q49. What is the Schedule Basis Memorandum (SBM) and what should it contain?

Answer: A Schedule Basis Memorandum (SBM) is a standalone document that explains and justifies the assumptions, methodologies, and constraints underpinning the project schedule. It is often a contractual submission requirement. A comprehensive SBM typically includes: project overview, scope basis, scheduling methodology, calendar assumptions, logic and sequencing basis, resource loading approach, interface and risk register references, key assumptions and exclusions, and a list of outstanding issues. The SBM gives the schedule narrative that the P6 file alone cannot communicate.

Q50. How would you improve an organisation’s scheduling maturity using Primavera P6?

Answer: Improving scheduling maturity involves several dimensions:

Standardisation – Implementing standard WBS templates, activity code dictionaries, naming conventions, and calendar libraries in the P6 Global database.
Training – Certifying schedulers through Oracle University P6 training and planning engineer development programmes.
Governance – Establishing schedule review boards, baseline approval processes, and update reporting cycles.
Integration – Connecting P6 with cost management, risk, and document control systems.
Benchmarking – Applying DCMA 14-Point and AACE International recommended practices to measure and improve schedule quality.
Reporting – Developing standardised dashboards that communicate schedule performance clearly to project sponsors and clients.
