Work Order: Everything You Need to Know for Efficient Task Management

what is a work order and how to use it

A work order is a formal document that authorizes, organizes, and tracks a specific job such as maintenance, repair, service, or construction work. It outlines exactly what needs to be done, where the work will happen, who is responsible, which materials and labor are required, and when the task must be completed. For operations managers, maintenance teams, and business owners, work orders are not administrative paperwork. They are the backbone of controlled, scalable operations.

Without a clear work order process, teams rely on verbal instructions, emails, or scattered notes. That leads to missed tasks, unclear accountability, cost overruns, and delayed billing. With a structured work order system, businesses gain visibility into workload, costs, timelines, and performance.

What Is a Work Order?

A work order is an official instruction that authorizes work to begin. It converts an identified need—such as a broken asset, scheduled maintenance, or a construction task—into a documented, trackable job.

Work orders are used across industries including facilities management, manufacturing, construction, hospitality, healthcare, and field services. In each case, they provide a standardized format for capturing operational details and ensuring nothing is missed.

A properly written work order:

  • Sets clear expectations for technicians and contractors
  • Defines scope and prevents unauthorized work
  • Creates accountability through assignment and approval
  • Tracks labor, materials, and time spent
  • Provides documentation for audits, compliance, and billing

Over time, completed work orders become a powerful data source. Businesses use them to identify recurring issues, evaluate technician performance, plan preventive maintenance, and forecast future costs.

At its core, every work order answers five questions:

  1. What work needs to be done?
  2. Where will it be done?
  3. Who is responsible?
  4. What resources are required?
  5. When must it be completed?

How Does a Work Order Differ From a Work Request and Purchase Order?

Understanding the difference between these documents is critical for efficient operations and accurate accounting.

Work Order vs Work Request

A work request is a notification. It communicates that something needs attention but does not authorize action. For example, an employee reports a malfunctioning machine or a tenant submits a maintenance request.

A work order is created only after that request is reviewed and approved. The work order authorizes the task, assigns responsibility, sets priority, and allocates resources. In other words, a work request identifies a problem, while a work order initiates the solution.

AspectWork RequestWork Order

Priority definedSometimesAlways
Resources allocatedNoYes (labor, tools, materials)
Tracking and reportingLimited or noneFull tracking from start to completion
Example“The conveyor belt is making noise.”“Inspect conveyor belt, replace worn bearing, test operation.”

Work Order vs Purchase Order

A purchase order is a financial document used to procure goods or services from a vendor. It specifies quantities, pricing, and payment terms. A work order, by contrast, focuses on execution.

In many businesses, both are used together. A work order authorizes the job, while a purchase order covers the materials or subcontracted labor needed to complete it. Separating these functions helps businesses track material costs and labor costs accurately.

Step-by-Step Work Order Process

A standardized work order process ensures consistency, regardless of job size or urgency.

1. Identify a Maintenance Task

The process begins when a task is identified. This may be reactive, such as equipment failure, or proactive, such as scheduled inspections. In construction, it may involve a defined task within a larger project scope.

Clear identification reduces ambiguity and prevents unnecessary rework.

2. Submit a Work Order Request

The requester documents the issue, including location, urgency, and any supporting details. Strong requests lead to better prioritization and faster resolution.

3. Review the Request

A manager evaluates priority, scope, risk, and resource availability. Some requests are approved immediately, while others may be deferred, bundled, or rejected.

4. Create a New Work Order

Approved requests are converted into formal work orders. This step defines tasks, assigns personnel, estimates time, and lists required tools or materials.

This is also where cost planning happens. Understanding fixed costs versus variable costs helps ensure the job is priced and scheduled correctly.

5. Assign a Work Order

The work order is assigned to a qualified technician, contractor, or team. Effective assignment considers skills, availability, and workload.

6. Complete and Close Out the Task

Once the work is finished, actual labor hours, materials used, and completion notes are recorded. Closing the work order finalizes the job and updates maintenance or project history.

Many businesses pair this step with estimates software to compare estimated versus actual costs and improve future planning.

Types of Work Orders

Different scenarios require different work order types.

Preventive Work Orders

Scheduled tasks such as inspections, servicing, and cleaning. Preventive work orders reduce downtime and extend asset life.

Corrective or Reactive Work Orders

Unplanned repairs addressing equipment failure or damage. Excessive corrective work often signals weak preventive maintenance.

Emergency Work Orders

High-priority tasks requiring immediate action, such as safety hazards or system failures.

Inspection-Driven Work Orders

Tasks generated from audits, inspections, or compliance checks.

Construction Work Orders

Used to authorize specific jobs or changes within construction projects. These often align with estimating, scheduling, and billing workflows like progress billing and milestone billing.

Key Components of a Work Order

Operations team managing and assigning work orders

Every effective work order includes:

  • Request details (requester, date, description)
  • Job details (location, priority, estimated duration)
  • Resource requirements (tools, parts, skills, costs)
  • Assignment (technician or team)
  • Authorization (approver)
  • Completion data (actual hours, materials used, notes)

Standardized government examples of work order documentation are available through official work order forms published by the U.S. General Services Administration, which demonstrate how structured records support accountability and compliance.

Tips on How to Write Effective Work Orders

Understand the Work Requested

Before writing the work order, clarify the exact scope of the task. Make sure the problem, desired outcome, and any constraints are understood upfront. Vague descriptions often lead to back-and-forth questions, delays, and unnecessary rework.

Consider the Resources Needed

Identify the labor, materials, tools, and access required to complete the job. Thinking through resources in advance helps avoid mid-task interruptions and supports more accurate overhead tracking and cost control.

Be Specific Yet Succinct

Include clear instructions, locations, and expectations, but avoid excessive detail. The goal is to give technicians everything they need to act confidently without overwhelming them with unnecessary information.

Create Your Own Work Order Checklist

A simple checklist ensures consistency across jobs and team members. Standardized steps reduce missed tasks, improve quality control, and make it easier to review completed work orders.

Set Realistic Estimates and Timeframes

Base time and cost estimates on past jobs whenever possible. Realistic timelines improve scheduling, set clear expectations, and support downstream workflows such as hourly vs flat rate pricing.

Basic Work Order Template (What to Include)

A good work order template keeps jobs clear, consistent, and easy to complete. Whether you’re using paper, Excel, or a digital tool, every work order should follow the same core structure so nothing gets missed.
