What’s a Statement of Work (SOW) and How to Make One

Project management’s behind-the-scenes is crazy! You have to define project scope and deliverables, create, review, and organize documents, and we mean a lot of them. But if there’s one document you can’t afford to overlook, it’s the Statement of Work (SOW).

Wait, what’s a Statement of Work, anyway? How do you create a solid SOW? And is there any way to simplify it?

These are questions a lot of people have, and we’re here to answer them.

But until then, grab a snack 🍪 or a hot cup of tea 🍵 Because we can already tell this is going to be a long (and exciting) one 😆.

Happy reading!

What is a Statement Of Work (SOW)?

If you’ve been searching for a Statement of Work (SOW) definition online, you’ve probably come across a lot of confusing technical jargon. So simply put, an SOW is a formal document that highlights the specifics of a project: the objectives, deliverables, scope of work, timelines, payment terms, and everything in between.

In other words, it’s a detailed contract that outlines all the agreed-upon scope of services between the involved parties and makes sure everything specified gets executed on time and within budget.

In an ideal world, the person in charge of managing the SOW should improve the efficiency rate of operations, minimize the project risks, manage suppliers and negotiators and of course track the project success.

Why does a Statement of Work (SOW) matter?

Now, you’re probably thinking things like:

So why are we talking about the Statement of Work (SOW) anyway? Surely, it’s just a formality, and we should be focused on the project itself… right?

Wrong.

Of course, the execution of your project is and should be the main focus, but ultimately without a solid SOW, you’re setting yourself up for missed deadlines, and budget overruns from the get go, and it’s not hard to see why!

A Statement of Work (SOW) matters because it lays the groundwork for your entire project. Just think about it, you are outlining the project’s objectives, scope, deliverables, timelines, payment terms.

The end result of all this? Each one knows what’s to be done, by whom, and when, and no part of the project gets missed out this way.

Does it get any better than that? And the answer is, yes, it does! Statement of work makes it a no-sweat for project managers to track each project phase’s progress, prevents potential risks and disputes down the line, and, most importantly, keeps the project on budget.

So, we can safely say that’s an indispensable document for both the client and the service provider.

The different types of Statement of Work

Now that we have established what a Statement of work is and why it’s important to have one in place, let’s dig deeper to know the three different types of SOW companies use.

Design (detail) SOW

This type of SOW defines everything needed to get the job done. It goes over exactly how the work should be completed by suppliers and what processes they need to follow.

But it doesn’t stop there, it also covers the finer details too, like industry regulations, payment terms, quality standards, and even how materials will be measured and approved.

And needless to say, when a company uses a design SOW, they’re fully responsible for how the project turns out and take on all the risks tied to its quality.

Let’s illustrate this with an example 👇

Let’s say a company is building a new data center and hiring an engineering firm to handle the electrical system design. The SOW might highlight things like 👇

• All electrical wiring must follow ISO and local safety standards
• Only copper wiring cables of a specific gauge should be used
• Final blueprints must be submitted within 30 days
• The system must support a minimum load of 500kW
• All materials must be pre-approved by the client before use

Level of effort

Unlike a design SOW, a Level of Effort (LOE) SOW specifies time and resources rather than specific deliverables. You’ll typically see this type used for short-term contracts or ongoing work.

🧠 Let’s paint a clearer picture here with a real-world example:

Say a tech company hires a machine learning consultant to help add a video to text converter using AI. The SOW can state things like 👇

• The consultant will provide 20 hours of support per week
• For a total of 6 months
• The consultant will be responsible for training and testing the AI model with various audio inputs to accurately convert video speech to text, monitoring the model’s performance, and providing feedback on algorithm improvements.

Performance-based statement of work

A Performance-Based SOW is a bit different from the other types, it’s all about the results, not the process, so instead of outlining how a task should be done, it focuses on what needs to be achieved and that means the service provider has the freedom to choose how to get the job done, as long as they deliver the expected outcomes.

💡 Did you think we forgot about you? Don’t worry, here is our example 👇

Imagine a software company hires a dev agency to build a new content aggregator feature for their platform. The SOW might include:

• Aggregate blog content from at least 50 unique sources within 2 months
• Make sure the aggregator updates content in real time or with minimal delay
• Achieve a 99.9% uptime for the feature by the end of the quarter

Let’s say that one more time: the company here isn’t telling the agency how to build it; it just cares about the final outcome. It’s totally up to the dev agency to choose the tech stack, workflows, and tools to deliver on those goals. Simple as that.

3 Common mistakes to avoid in an SOW

Not involving stakeholders

As a business owner or a project manager, you can’t afford to craft SOW in the dark without involving team members and stakeholders in the process. You might have a great vision and a strategic plan, but without input from the hands-on people who are familiar with the day-to-day work, things can get messy (very messy!)

You’re likely to miss very important details like how long something really takes or what resources are needed for a specific task, which can lead to poor team buy-in, pushback, or even delays once the project is underway, and that brings us to our next mistake.

Not clearly defining components

One of the biggest and most impactful mistakes you can make is signing off on an SOW that doesn’t clearly define components like timelines, payment terms, acceptance criteria, and specific deliverables. Because when you don’t clearly define these elements, you are opening the door for confusion on both sides, the client and the vendor.

Just imagine this for a second: the project drags on longer than expected because you didn’t build in enough buffer time ⏳, or there’s a disagreement over costs because some fees weren’t accounted for.

And to make matters worse, both sides end up with different ideas of what “finished” actually means, due to undefined acceptance criteria.

Not a great situation, right? 😬

Neglecting Risk and Change Management

In the project management world, you will always need to face change and if your SOW doesn’t contain enough detail on how to handle unexpected issues or modifications, hate to break it to you, but you’re not fully protected!

When things go off track and there’s no pre-established change management process, you and the client might have totally different expectations about how to handle scope creep, added costs, or delays. The payoff? Disputes, extra work, and potentially even legal trouble if there’s no agreed-upon framework for managing changes.

So the moral of the story is that if your SOW doesn’t cover how to manage scope changes, you’re leaving room for misunderstandings and risks that could disrupt the whole project.

How to Make an Effective Statement of Work?

We hate to sound like a broken record, but we’ll just need to say this one more time: a Statement of Work is an agreement between a client and a vendor that outlines what’s being done, how it’s being done, and under what terms.

The reason we are repeating ourselves is because this will determine the elements we need to include in our SOW and to make your life much easier, we’ll break it all down using a real-world example.

Here is a bit of context 👇

Let’s assume that the Paymo board decided to enhance their user engagement by introducing a new AI feature to offer app feature recommendations based on what users already do most (task tracking, time logging, or project updates, etc)

Sounds good? Let’s get our hands muddy 👷🏻‍♂️

Project Overview

This step includes a brief summary that outlines what the work plan looks like, why it’s being done and who are the involved parties (client + vendor).

Scope of work

This is the meat of the SOW, because it outlines what’s included (deliverables and services) what’s not included (out-of-scope items) and how work will be done (methodologies or processes).

Work Breakdown Structure

In this step, you will have to specify what will be delivered, in what format, and essentially the project length.

Timeline and milestones

This fourth step should highlight the start and end dates and all the big milestones in between.

And here’s a friendly tip: always add a bit of buffer time. Things rarely go exactly as planned, and a little wiggle room in your budget can go a long way 😌.

Acceptance criteria

This element determines project requirements, how deliverables will be reviewed and approved: who gives the green light, how many rounds of revisions are allowed, and what qualifies as “done”.

Performance Standards

This element might sound similar to acceptance criteria, but it’s a bit different because it’s not about what gets delivered, but how well it performs.

Here, you’ll outline the specific benchmarks and quality standards the deliverables need to meet, using metrics like load times, error rates, uptime, or any other measurable factor that shows if things are on track.

Required technology tools

List any hardware, software, or platforms the team will need to use during the project, whether it’s design tools, development environments, or any specific device.

Change management process

Here, you will define how you will handle unexpected scope changes, timeline extensions, and unforeseen costs that may occur during the project.

Payment terms

This step discusses the terms and conditions of payment related to the project, such as the pricing model, Payment deadlines, fees for overdue payments, etc.

Other

It goes without saying that not everything in a project fits neatly into the usual SOW sections. Like for instance, security protocols, compliance requirements, travel and accommodations, post-project maintenance, and third-party dependencies among others.

Closure

This is where the project officially comes to an end. It covers who’s in charge of delivering the final work, who reviews and signs off, and how everything gets closed, documented, and archived.
