ABOUT THE TEMPLATE

A Structured Framework for Developing the Project Schedule Basis

The Project Schedule Basis Template is an Excel-based scheduling workbook designed to provide a structured and traceable method for documenting the foundation behind a project schedule. It helps teams define schedule requirements, establish source inputs, document methodology, set time rules, develop duration assumptions, and integrate controls.

The template connects project context with schedule requirements, source information, scheduling methodology, calendars, activity and duration basis, logic and constraints, milestones, resources, cost, progress, uncertainty, assumptions, and governance. This creates a clear record of why the schedule is structured, sequenced, timed, estimated, measured, and controlled in the way it is.

Establish Project Context

Define the project and schedule context, purpose, planning horizon, contractual requirements, reporting needs, required detail, milestones, interfaces, coding, and project-controls expectations that establish what the schedule must satisfy.

Define Schedule Methodology

Document the source information behind the schedule, then define the scheduling methodology, WBS, activity structure, coding conventions, milestone rules, update practices, baseline approach, and other rules used to construct the schedule.

Define Time, Duration & Logic Basis

Establish calendars, working time, date controls, duration methods, productivity assumptions, activity rules, relationship conventions, constraints, leads, lags, interfaces, and network principles that determine how schedule dates are developed.

Integrate Controls Governance

Connect milestones, resources, cost and progress with schedule-specific risks, assumptions and uncertainty, then establish review, approval, effective dates, revision history, and governance controls for maintaining the Schedule Basis.

HOW TO USE THE TEMPLATE

From Schedule Context to Controlled Basis

The template should be used as a progressive development workflow rather than as a collection of separate worksheets. Start by establishing project context and requirements, identify the information supporting the basis, define scheduling rules, establish the time and duration model, develop logic and controls principles, capture uncertainty, and complete review and approval.

1. Establish the Project Context

Begin with the Project Profile and record the project, contract, schedule, ownership, delivery environment, planning horizon, and other information needed to understand where and why the Project Schedule Basis will be applied.

2. Define Schedule Requirements

Use Schedule Requirements to establish what the schedule must accomplish. Capture contractual, reporting, detail, milestone, coding, interface, stakeholder, and project-controls requirements before defining the detailed scheduling approach.

3. Document the Basis Inputs

Use Schedule Basis Inputs to identify the information supporting schedule development. Record relevant scope, engineering, procurement, construction, quantities, resources, cost, interfaces, reference schedules, sources, revisions, ownership, and confidence.

4. Establish the Scheduling Rules

Use Methodology & Structure to define how the schedule will be constructed and managed. Establish planning levels, WBS, activity conventions, coding, milestones, critical path methodology, updates, baseline practices, and other scheduling rules.

5. Establish the Time Model

Use Calendars & Date Controls to define the working-time and date conventions that will govern schedule calculations. Establish calendars, shifts, holidays, exceptions, time zones, project dates, contractual dates, and status-date practices.

6. Establish Duration & Network Logic

Use Activity & Duration Basis to document how activity durations are developed from quantities, productivity, crews, resources, formulas, benchmarks, and other evidence. Then establish relationship, lag, constraint, interface, and network rules.

7. Integrate Project Controls

Use Milestones & Controls to connect the schedule with contractual and management milestones, resources, cost, progress measurement, weighting, and reporting. Ensure these integration rules reflect the project’s actual control requirements and intended use.

8. Manage Uncertainty & Govern

Use Risk & Uncertainty to capture schedule-specific assumptions, risks, uncertainty, effects, treatments, owners, and triggers. Complete Review & Approval and Revision History to establish acceptance, control changes, and maintain the Schedule Basis as a governed project document.

Build the Basis Before the Schedule

A reliable schedule begins with clearly documented requirements, source information, scheduling rules, time conventions, duration assumptions, network principles, controls, and uncertainty. Use the template to establish this foundation before and throughout schedule development, then update it when the underlying basis changes.

SCHEDULE BASIS DEVELOPMENT

Evaluate the Key Dimensions of a Reliable Schedule Basis

A reliable Schedule Basis connects project requirements, source information, scheduling methodology, time controls, duration assumptions, logic, project-controls integration, uncertainty, and governance into one structured foundation. The template provides a traceable basis for explaining how the project schedule is developed and controlled.

Project Context

Establish the project and schedule context, purpose, ownership, planning environment, schedule identity, delivery conditions, and key information required to understand how the Schedule Basis will be developed and applied.

Schedule Requirements

Define the contractual, reporting, planning, detail, milestone, coding, interface, stakeholder, and project-controls requirements that the schedule must satisfy before the detailed scheduling approach is established and documented.

Schedule Basis Inputs

Identify and document the scope, WBS, engineering, procurement, construction, quantities, resources, cost, interfaces, reference schedules, external information, sources, revisions, owners, and confidence supporting Schedule Basis development.

Methodology & Structure

Define the scheduling methodology, planning levels, WBS, activity structure, milestone conventions, coding, critical path approach, update practices, baseline rules, out-of-sequence treatment, and governance conventions for schedule development.

Calendars & Date Controls

Establish calendars, working patterns, shifts, holidays, exceptions, time zones, project dates, contractual dates, data dates, status dates, and other time conventions that influence schedule calculations, durations, and forecasts.

Activity & Duration Basis

Document activity definitions, duration methods, quantities, productivity, crews, resources, formulas, benchmarks, lead times, testing, commissioning, uncertainty, exclusions, and validation methods used to establish credible activity durations.

Logic & Controls Integration

Define relationship types, open ends, leads, lags, constraints, interfaces, milestone drivers, and network principles, while establishing the basis for milestones, resources, cost, progress measurement, weighting, and reporting.

Risk, Review & Governance

Capture schedule-specific risks, assumptions, uncertainty, potential effects, treatments, ownership, and triggers, then complete review, approval, effective dates, and revision controls to maintain a governed and traceable Schedule Basis.

SCHEDULE BASIS DOCUMENT STATUS

Use Status to Track the Schedule Basis Lifecycle

The template uses structured status classifications to help project teams understand the current stage of the Schedule Basis, identify whether development or review actions remain, confirm approval requirements, control revisions, and determine whether the document remains effective or has been superseded.

Draft

Basis Being Developed

The Schedule Basis is being prepared and project information, requirements, source inputs, methodology, time controls, duration assumptions, logic, controls, risks, and other supporting information are being progressively documented for review.

Under Review

Basis Being Reviewed

The Schedule Basis has been prepared for formal review, and designated reviewers are examining its requirements, inputs, methodology, assumptions, scheduling rules, controls, supporting evidence, and other information before approval.

Revision Required

Updates Being Addressed

The Schedule Basis has been reviewed and requires identified updates, clarifications, additional evidence, or corrections before it can proceed to formal approval. Required actions should be documented and tracked to completion.

Approved

Basis Authorised

The Schedule Basis has received the required review and approval, with its methodology, assumptions, scheduling conventions, controls, and supporting information formally accepted for use in developing and managing the applicable project schedule.

Effective

Basis In Use

The approved Schedule Basis is currently effective and being used as the documented foundation for schedule development, updates, reviews, controls, and related project decisions within the defined project and schedule environment.

Superseded

Previous Basis Retained

The Schedule Basis is no longer the current governing version because a subsequent revision has replaced it. The superseded version should be retained with its approval and revision history to preserve traceability and document control.

FROM PROJECT CONTEXT TO CONTROLLED SCHEDULE BASIS

Build a Traceable Foundation for Your Project Schedule

A reliable project schedule begins with more than activities and dates. The template connects project context, schedule requirements, source inputs, methodology, time controls, duration assumptions, logic, project-controls integration, uncertainty, and governance into one structured Schedule Basis.

Establish Project Context

Understand the Schedule Environment

The template begins by establishing the project and schedule context, including project identity, delivery environment, schedule purpose, ownership, planning horizon, contractual setting, and other information needed to understand how the Schedule Basis will be developed and applied.

This creates a clear reference point before detailed scheduling rules are established and ensures that the basis reflects the actual project environment and intended schedule purpose.

From Schedule Rules to Controlled Basis

Connect Scheduling Decisions With Governance

A Schedule Basis becomes useful when its requirements, source information, methodology, time rules, duration assumptions, logic, controls, uncertainty, and governance remain connected. The template provides a structured path from establishing the foundation to reviewing, approving, and maintaining it.

Establish the Time Model
Define calendars, working patterns, shifts, holidays, exceptions, time zones, project dates, contractual dates, data dates, status dates, and other conventions that influence schedule calculations and forecast dates.

Define Duration & Logic Basis
Document activity duration methods, quantities, productivity, crews, resources, benchmarks, formulas, relationship types, leads, lags, constraints, interfaces, and network principles supporting schedule development.

Integrate Project Controls
Establish the basis for contractual and management milestones, resources, cost, progress measurement, weighting, and reporting so the schedule connects consistently with the wider project-controls environment.

Manage & Govern the Basis
Capture schedule-specific risks, assumptions, uncertainty, potential effects, treatments, owners, and triggers, then complete review, approval, effective dates, and revision controls to maintain a traceable and current Schedule Basis.
