Scheduling Basics

Core concepts every project manager encounters on day one.

Glossary Scheduling

Gantt Chart

A horizontal bar chart that displays project tasks against a calendar timeline, showing start dates, durations, dependencies, and the critical path at a glance.

Read the Gantt chart definition
Glossary Scheduling

Project Schedule

The complete time model of a project — tasks, durations, dependencies, assigned resources, and milestones — integrated into a single living plan.

Read the project schedule definition
Glossary Scheduling

Milestone

A zero-duration task that marks a significant point in the project — a deliverable handoff, phase boundary, or approval — with no work effort attached.

Read the milestone definition
Glossary Scheduling

Task Dependency

A logical relationship between two tasks that controls their sequence — which must finish or start before the other can proceed, including all four link types and lag.

Read the task dependency definition
Glossary Scheduling

Work Breakdown Structure

A hierarchical decomposition of project work into phases, deliverables, and tasks — the foundation that makes scope visible and scheduling possible.

Read the WBS definition
Glossary Scheduling

Predecessor

A task that must begin or finish before a dependent task can proceed. Predecessor links define the sequence network that drives critical path calculations.

Read the predecessor definition
Glossary Scheduling

Waterfall

A sequential project methodology where each phase completes and is approved before the next begins — initiation, planning, execution, testing, closure — with gate reviews between phases.

Read the waterfall definition
Glossary Scheduling

Lag

A positive delay added to a task dependency link — the mandatory waiting period between a predecessor reaching its trigger event and a successor being allowed to start or finish.

Read the lag definition
Glossary Scheduling

Task Duration

The working-time span assigned to a project task from its scheduled start to its finish — the length of the bar on the Gantt chart, used with resource calendars to compute finish dates.

Read the duration definition
Glossary Scheduling

Project Calendar

The definition of which days and hours count as working time — the foundation that converts task duration into real start and finish dates, taking weekends, holidays, and shift patterns into account.

Read the project calendar definition

Critical Path Method

The concepts behind CPM scheduling — how Maverick calculates your finish date and identifies where you have flexibility.

Glossary Critical Path

Critical Path

The longest chain of dependent tasks in your schedule — it determines the minimum project duration and has zero float. Any delay on a critical task directly delays the project end date.

Read the critical path definition
Glossary Critical Path

Float

The amount of time a task can be delayed without affecting the project end date. Also called slack. Tasks on the critical path have zero float.

Read the float definition
Glossary Performance

Project Baseline

A frozen snapshot of the approved schedule — task start dates, finish dates, and durations — saved before work begins and used to measure how much the project has drifted.

Read the baseline definition
Glossary Critical Path

Schedule Compression

Techniques that shorten the project end date without reducing scope — crashing adds resources to critical tasks, fast-tracking overlaps tasks that were planned as sequential.

Read the schedule compression definition
Glossary Critical Path

Network Diagram

A visual logic map of all tasks and their dependency links — the underlying structure the scheduling engine traverses to calculate the critical path and earliest possible project completion.

Read the network diagram definition
Glossary Critical Path

Free Float

The time a task can be delayed without delaying any of its immediate successors — distinct from total float, which measures delay tolerance against the overall project end date.

Read the free float definition
Glossary Critical Path

Crashing

A schedule compression technique that shortens the critical path by adding resources to critical tasks — trading increased cost for a reduced project end date.

Read the crashing definition

Resources & Performance

Concepts for managing people, equipment, and measuring whether the project is on track.

Glossary Resources

Resource Leveling

The process of adjusting task dates to resolve resource over-allocation — when a person or machine is assigned more work than they can handle in the same time period.

Read the resource leveling definition
Glossary Performance

Earned Value Management

A technique that integrates scope, schedule, and cost into a single performance measurement — comparing planned value, earned value, and actual cost to reveal variance.

Read the EVM definition
Glossary Resources

Resource Allocation

Assigning people, equipment, and materials to tasks and balancing their workload — ensuring the schedule reflects what the team can actually deliver, not just what is theoretically planned.

Read the resource allocation definition
Glossary Resources

Resource Utilization

The percentage of a resource's available capacity assigned to project tasks — the measure that reveals whether team members are over-allocated, under-allocated, or balanced across the schedule.

Read the resource utilization definition
Glossary Performance

Percent Complete

A numeric record of how much of a task's work is done, displayed as a progress fill inside the Gantt chart bar and used as the primary input for earned value calculations.

Read the percent complete definition

Project Foundations

The concepts that frame a project before scheduling begins — authorization, scope, people, and lifecycle structure.

Glossary Foundations

Project Charter

The document that formally authorizes a project, names the project manager, and records high-level objectives, scope, budget constraints, and stakeholder roles before work begins.

Read the project charter definition
Glossary Foundations

Project Lifecycle

The sequence of phases a project passes through from initiation to closure — each with defined deliverables and a gate review before the next phase begins.

Read the project lifecycle definition
Glossary Foundations

Project Scope

The defined boundary of what the project will and will not deliver — the work required to produce all approved deliverables, plus explicit exclusions that prevent scope creep.

Read the project scope definition
Glossary Foundations

Deliverable

Any tangible, verifiable output the project is required to produce — a document, system, structure, or product — that can be handed over and accepted by the customer or sponsor.

Read the deliverable definition
Glossary Foundations

Stakeholder

Any person or group with an interest in a project's outcome — sponsor, customer, team, regulator, or end user. Identifying stakeholders early prevents late-stage surprises.

Read the stakeholder definition
Glossary Foundations

Scope Creep

The gradual, uncontrolled expansion of project work beyond its approved boundaries — without adjustments to schedule, budget, or resources. The leading cause of project overruns.

Read the scope creep definition
Glossary Foundations

Risk Register

A living log of identified project risks — each with a probability score, impact rating, owner, and response plan — used to manage uncertainty and prevent surprises throughout delivery.

Read the risk register definition
Glossary Foundations

Change Request

A formal proposal to modify a project's approved scope, schedule, or budget — requiring evaluation and approval before any baseline change takes effect, preventing uncontrolled scope creep.

Read the change request definition
