As a project manager, you’ve likely encountered the terms “statement of work” (SOW) and “scope of work” frequently. Both play a pivotal role in project planning and execution. However, scope of work and statement of work refer to distinct documents with unique purposes. Understanding the key differences empowers you to utilize each effectively.
In this article we’ll compare statement of work vs scope of work. You’ll learn
- The purpose and components of a statement of work
- The purpose and components of a scope of work
- When to use each document
- Best practices for crafting an effective SOW or scope
Let’s dive in!
Statement of Work Overview
A statement of work is a formal document that outlines key details about a client-vendor project engagement. It serves as a legally binding agreement defining project parameters and expectations
A thorough SOW generally includes:
-
Project overview and objectives – High-level summary of the initiative’s goals, deliverables, timeline and participating stakeholders.
-
Detailed scope of work – Granular description of specific tasks and milestones required to execute the project.
-
Terms and conditions – Payment terms, intellectual property rights, liability, and other binding clauses that govern the business relationship.
-
Acceptance criteria – Standards that completed deliverables must meet for signoff and payment.
-
Change management – Procedures for addressing modifications in project scope or timelines.
Scope of Work Overview
The scope of work is a key component within an overarching statement of work document. The SOW scope section provides a detailed project task breakdown, including:
-
Project phases – Stages such as planning, development, testing and training
-
Tasks – Specific activities required in each phase
-
Deliverables – Tangible work products for each phase
-
Timelines – Target completion dates for phases and deliverables
-
Roles and responsibilities – Team members accountable for each task or deliverable
While the SOW covers the broad project framework, the scope of work zooms in on the tactical “how” for getting work done. It transforms objectives into concrete execution steps.
Key Differences Between SOW and Scope
Though related, statement of work and scope of work have distinct purposes:
Purpose
-
SOW: High-level project agreement between client and vendor
-
Scope: Detailed project execution plan for internal use
Contents
-
SOW: Objectives, terms, change management, acceptance criteria
-
Scope: Phases, tasks, timelines, roles
Audience
-
SOW: External document shared with client
-
Scope: Internal document for project team
Depth
-
SOW: Broad overview
-
Scope: Deep project detail
Legality
-
SOW: Legal contract
-
Scope: Non-binding plan
In essence, the SOW provides the “what and why” and the scope provides the “how and who”. Both are integral to project success.
When to Use Each Document
Since SOWs and scopes serve different purposes, when you need one versus the other depends on the project scenario:
Statement of work: Necessary for client-vendor engagements to align expectations and formalize agreement. Required whenever project success hinges on clarifying responsibilities between organizations.
Scope of work: Ideal for internal initiatives where you control resourcing and delivery. Provides execution details to your own team.
In most cross-company projects, you’ll draft an SOW with a scope section for both parties to sign. In simpler internal efforts, a scope may be sufficient alone to guide work. Analyze project complexity and risk to choose the best option.
How to Craft an Effective SOW
Follow these tips to draft a clear, comprehensive statement of work:
-
Include an executive summary – Concisely state the project goals, timeline, budget and team roles
-
Define the scope in detail – Provide granular delivery specifics in the scope section
-
Specify measurable acceptance criteria – Outline precise, objective standards for deliverable sign off
-
Document payment terms thoroughly – Leave no ambiguity around invoicing and compensation
-
Add a change process – Detail how modifications in timeline or budget will be addressed
-
Use clear language – Avoid technical jargon and write for a non-technical audience
-
Review legally – Have legal counsel examine the SOW before finalizing
Check, double check and triple check your statement of work before sending to clients. An inaccurate or incomplete SOW jeopardizes project success.
Best Practices for an Effective Scope
For internal scope documents, remember:
-
Break down work into sprints – Organize tasks into short, collaborative sprints for efficiency
-
Assign owners – Identify specific individuals accountable for each task or deliverable
-
Estimate timelines – Gauge hours, days or weeks required to complete work items
-
Define done – Specify clear standards and expectations for finished tasks
-
Visualize workflows – Use charts and diagrams to map task relationships and dependencies
-
Update frequently – Adjust scope continually as priorities or timelines shift
Great scopes translate strategic objectives into tangible workflows so teams can execute efficiently. Revisit your scope often as projects evolve.
Bringing It All Together
A statement of work and detailed scope provide complementary project perspectives – the forest and the trees. While an SOW grants critical alignment for client engagements, the scope empowers nimble execution.
Mastering both documents is invaluable for project managers seeking to delight stakeholders with predictable, high-quality delivery. With a disciplined approach to planning, the difference between project failure and phenomenal success often comes down to just a few pages.
What specifics should a statement of work contain?
A statement of work must contain all the necessary information to function as a well-designed road map for your project’s successful completion.
Basics should be included, such as:
- An introduction to your project
An introduction serves to identify the project and whoever is involved for anyone reading.
- The purpose of your project
It’s important to define the purpose and importance of the project and the general objectives it will achieve.
- The scope of work
The scope of work should fully detail how the company plans to achieve the project objectives described in the purpose section.
Define where the project will be realized. Can it be done remotely, or will it be an onsite project?
This section will provide more detail than the section dedicated to the scope of work. It will outline what all stakeholders and collaborators need to do to complete the project successfully.
Project milestones that have been identified should be included in this separate section. In this manner, the project is easily divided into sections so that all meet goals quickly.
Include a section that lists all deliverables and the date that each is due. This will avoid misunderstandings about what is expected from all parties involved.
The project schedule needs to list the amount of time allotted for each task with a specified beginning and end, the deliverables with deadlines, and billable hours.
- Project standards and testing
If your project is specific to an industry that has legal and safety standards, this is the section where these should be identified and explained. If testing is involved, this section should specify this as well as who is involved, what equipment is used, and where testing fits into the project timeline.
- A definition of project success
This SoW section will define what all stakeholders consider project success, and all stakeholders should agree upon this definition in the project in preliminary discussions.
Requirements may include using specific equipment, security clearances, certifications, and other things necessary to complete the project successfully.
This section should be drafted with the aid of both the company finance department and the company attorney or legal department. This section will detail the costs of the project and the payment schedule, which may be connected to the completion of milestones or the consignment of deliverables. In order to properly set up financial processes, it is essential to understand invoice payment terms.
Other sections may be included to specify relevant information not found in other sections. It may concern security, use or restriction of hardware and software, and any post-project necessities.
Project security can be an important consideration and merit a separate section in a statement of work document. This is particularly pertinent if any part of the project includes record management and the storage of sensitive data that is subject to privacy protection or remotely managed physical security at project sites.
Security is critical to a company’s and often to a project’s success. Cyber-attacks or humans as the weak link in a security chain can pose a risk to the successful completion of any project for various reasons, including weak passwords or the use of unverified applications that could lead to exposed DVR security systems. These breaches will delay your project and compromise your company’s overall security.
Once you have created your statement of work, it has been successfully reviewed by legal counsel, and all parties have signed, you need to educate your teams on the project information and details. At regular intervals, check the project progress and stay updated as the project progresses. This will allow efficacious monitoring of whether the project is meeting goals and if goal achievement is on time.
When is a statement of work useful?
Well-conceived statements of work describe a project and define how it will proceed. It is especially useful when collaborating with external parties to your company because it details expectations, and this will contribute to preventing misunderstandings and to preventing disputes among the parties.
Upon the completion of a project, the success of that completion will refer back to the initial statement of work. Management will verify and evaluate if the completed project meets what was defined in the SoW. Successful project completion can also impact a business because it may translate into penalties or bonuses depending on the type of contract stipulated or even if the company receives full payment for work done.

What is a statement of work?
Some of the most complex statements of work documents are written for government contracts and are typically part of the RFP (request for proposal) or RFQ (request for quotation). You can also use a statement of work for internal projects when two different departments collaborate. The following parties generally receive a SoW:
What is a scope of work?
The scope of work typically discusses project needs and explains how a project’s goals will be met. This document will usually outline the work you’re going to perform during the project and includes details on the deliverables, timeline, milestones, and reports. A scope of work can stand alone if your project doesn’t require a statement of work.
How long is a statement of work?
As mentioned above, a statement of work can be a long document with many separate sections. The average statement of work is about 12 pages long, however, this varies depending on the project. Scope of work, on the other hand, is usually a considerably shorter document because it is provided as a single component inside the statement of work.
What is the difference between a statement of work and scope of work?
By examining the expressed purpose for Statements of Work and the Scope of Work, you can better understand how these documents differ.As mentioned previously, a Statement of Work is a formal document that describes the project goals, while a Scope of Work is a section within an SOW outlining how a team plans to deliver those outcomes.
