Used when work duration depends on manpower or equipment.
Level of Effort (LOE)
Has no fixed duration; it spans between two activities.
Used for support work like supervision or project management.
Start Milestone
Represents an important start event with zero duration.
Finish Milestone
Represents an important completion event with zero duration.
These activity types help control how schedules are calculated and managed in Primavera P6

What is a project in Primavera P6?
A project in Primavera P6 is a planned set of activities created to achieve a specific objective within a defined scope, time, and resources. In Primavera P6, a project: Has a start date and finish date Contains activities, relationships, and milestones Is used to plan, schedule, monitor, and control work Can be assigned resources, costs, and calendars Is managed within the Enterprise Project Structure (EPS) In simple terms, a project in Primavera P6 is the main container where all planning and scheduling information for a job (such as construction, engineering, or shutdown work) is organized and tracked from start to completion.
What are calendars in P6 and how are they used?
In Primavera P6, calendars define the working and non-working time used to schedule activities and resources. What are calendars in P6? A calendar in P6 specifies: Working days (for example: Monday–Friday) Working hours per day (for example: 8 hours/day) Holidays and non-working days Special work shifts or overtime Primavera P6 uses calendars to calculate: Activity start and finish dates Activity durations Resource work hours Types of calendars in Primavera P6 There are three types of calendars: Global Calendar Available to all projects in the database Typically used for standard company working time Project Calendar Available only within a specific project Used when a project has unique working rules Resource Calendar Assigned to individual resources Used when resources have different work schedules (shift work, part-time, etc.) How are calendars used in P6? Calendars are assigned to projects, activities, and resources When the project is scheduled, P6 uses the assigned calendar to: Determine which days are working or non-working Calculate activity start and finish dates Calculate resource units and costs If no specific activity calendar is assigned, P6 uses the project calendar by default Why calendars are important Ensure realistic schedules Prevent activities from being scheduled on holidays Allow accurate resource planning and cost calculation Support multiple shifts and site-specific working rules
What is a resource in Primavera?
In Primavera P6, a resource is any person, equipment, or material that is required to complete a project activity. Resources are assigned to activities to: Estimate costs Plan workload Track actual progress Control project performance Types of Resources in Primavera P6 Labor – engineers, supervisors, workers Non-labor – machines, equipment, tools Material – cement, steel, cables, etc. Each resource can have: Units (hours, days, quantities) Costs (rate per hour/unit) Availability limits By using resources, Primavera helps project managers plan, schedule, and monitor time and cost effectively.

What are activities in Primavera P6?
Activities in Primavera P6 are the individual tasks or work elements that must be performed to complete a project. They are the building blocks of the project schedule, and each activity represents a specific piece of work with a defined duration, start, and finish. Key points about activities in Primavera P6: Each activity has a start date, finish date, and duration Activities are linked to each other using relationships (FS, SS, FF, SF) Resources (labor, material, cost) can be assigned to activities Activities help determine the critical path of the project Progress is tracked by updating actual dates, remaining duration, or percent complete Types of activities in Primavera P6: Task Dependent – duration is driven by activity logic Resource Dependent – duration depends on assigned resources Level of Effort (LOE) – measures work based on other activities WBS Summary – summarizes activities under a WBS Milestone – represents key events (start or finish) Why activities are important: Activities allow planners and project managers to: Plan and sequence work accurately Monitor progress and delays Control time and cost Analyze schedule performance
What does P6 stand for?

What is Lag and Lead in Primavera?
What is Lag and Lead in Primavera P6? Lag and Lead are used in Primavera P6 to control the time gap between two activities in a schedule relationship. Lag Lag is a delay between two activities. It adds extra waiting time after the predecessor activity before the successor activity can start or finish. Lag is usually written as + days. Example: Activity A → Activity B (Finish-to-Start +3 days) Activity A finishes on Day 5 Activity B will start on Day 8 Because there is 3 days lag (waiting time) Simple Meaning: Lag = Waiting time between activities Lead Lead is the overlapping time between two activities. It allows the successor activity to start before the predecessor activity finishes. Lead is shown as a negative lag (-) in Primavera. Example: Activity A → Activity B (Finish-to-Start -2 days) Activity B starts 2 days before Activity A finishes. Simple Meaning: Lead = Activities overlap Short Definition Lag: Delay between activities (+ time) Lead: Overlap between activities (- time) If you want, I can also explain with a simple construction example used in Primavera planning (like concrete, curing, plaster work).

Why in primavera P6 schedule the total float for all activitity is negative?
one possible reason is that you dont have the correct dates in the project view->dates. try matching the project planned start date with the activity that kicks the programme off, and match the project must finish by date to the final activity in your programme.
What are relationships in Primavera P6 (FS, SS, FF, SF)?
In Oracle Primavera P6, relationships define how activities are connected and in what sequence they should be performed. There are 4 main types of relationships: 🔹 1. Finish to Start (FS) Definition: The successor activity cannot start until the predecessor activity finishes. Most commonly used relationship. Example: “Foundation must finish before walls start.” 🔹 2. Start to Start (SS) Definition: The successor activity can start only after the predecessor activity starts. Activities can run in parallel after starting. Example: “Excavation starts → Concrete pouring can also start.” 🔹 3. Finish to Finish (FF) Definition: The successor activity cannot finish until the predecessor activity finishes. Both activities may start at different times but must finish together or after. Example: “Testing must finish when development finishes.” 🔹 4. Start to Finish (SF) Definition: The successor activity cannot finish until the predecessor activity starts. Least commonly used. Example: “Old system can shut down only after new system starts.” 🔹 Quick Summary Table Relationship Meaning FS Finish → Start SS Start → Start FF Finish → Finish SF Start → Finish
When was Primavera Productions created?
Primavera Productions was created in 1983. Primavera Productions was founded by Joel Spolsky and other partners as a company focused on developing project management software for planning, scheduling, and controlling large and complex projects. The company quickly became known for creating powerful scheduling tools that were widely adopted in industries such as construction, engineering, manufacturing, aerospace, oil and gas, and information technology. The flagship software developed by the company was Primavera Project Planner (P3), which later evolved into Primavera P6, one of the most widely used project management and scheduling tools in the world. Primavera software helps project managers perform tasks such as: Creating project schedules Managing resources and costs Tracking project progress Analyzing delays and risks Controlling multiple large projects simultaneously Due to its strong capabilities in handling enterprise-level project management, Primavera became extremely popular among large organizations and government agencies. In 2008, the company was acquired by Oracle Corporation. After the acquisition, the software became part of Oracle Primavera, which includes several tools such as Oracle Primavera P6 for scheduling and project control. Today, Primavera P6 is considered one of the leading project management tools globally, especially for managing large-scale infrastructure and construction projects.
