PRD or Product Requirements Document template is universally considered the ultimate best friend of all product managers. However, it’s not quite as straightforward to make an effective PRD, and for many, it proves to be a real challenge. If it’s not given enough attention, you may end up with a pretty much useless list that brings little to no value. But if you will dedicate time and effort to preparing it, the product launch will most likely be a success.

The PRD is one of the key documents that the whole development team uses as a basis throughout the entire development process. There are a couple of ways you can maintain this document. One is to use a PRD platform like a spreadsheet, database, or word document. On the other hand, if your sector requires documentation formats according to the industry or government standards, you may have to create or follow a specific Product Requirements Document template. It’s worth noting that an effective PRD allows your team to work on the same page and have significant product development progress.

PRD should include essential things about your company and the product you are making. And it might be easy to get lost, especially if you have some doubts about what to add to the document.

But worry no more! This post will guide you in preparing a practical and useful PRD. So, stay with us to learn more.

What is a product requirements document?

Before jumping into writing a Product Requirements Document, we should try to understand what it really is. Basically, a PRD refers to a file containing information regarding the product you want to construct. Features, functionality, value, and purpose of the product you are going to build are just some of the details usually included in a PRD. Your organization’s development team will then use this document as a guide to create the outlined product. In most cases, PRD is used in waterfall settings where item delivery, design, and definition work hand-in-hand. But it’s worth noting that they are also quite popular in agile environments.

As we’ve already mentioned, you should include every important detail associated with the product release. Aside from the development process, PRD is also used in the product release process.

Although PRDs are designed to hint at the possible product implementation, they do not contain specific requirements for product launch.

Why is a Product Requirements Document important?

There are several reasons justifying the significance of crafting a practical Product Requirements Document. One is that it serves as a place that keeps the team members and other stakeholders in the same space with a shared understanding regarding the product. Ensuring that the delivery of features or products will succeed calls for effective collaboration between the organization’s development teams, marketing, support, sales, design, and engineering departments.

PRD is also essential as it sets the possible release time, ensures that the product can meet the customer’s wants, and maintains all contributors in the same place.

This document can be a starting point and basis for when the team can begin making relevant artifacts, such as mockups, wireframes, design documents, functional specifications, etc.

What should be included in a PRD?

Organizations are free to use different forms in making a Product Requirements Document. The PRD template you will use will vary depending on your industry, company, and team.

To give you an overview of how to create an effective PRD, here are some of the essential elements that should be present in your Product Requirements Document:

Goals and objectives

The first part of your PRD should explain the idea behind the development of a product. This is where you can write down the context regarding your product development and determine how you will connect the mission and vision of your product.

Aside from that, it is also vital to ensure that all problems the product is meant to address are clearly stated. This will definitely aid developers in building a product specifically designed for its purpose.

A smaller PRD is ideal, especially if it’s your company’s first one.

Key stakeholders

It is also essential to include the primary stakeholders associated with the product development when writing your Product Requirements Document.

A list of key stakeholders may include the product designers, developers, managers, and the document owner. Moreover, you should also involve the higher-ups to make the PRD more detailed.

User personas and user stories

The user persona is one significant factor affecting the product’s experience. Beyond that, it should also have the intention of helping the product reach its objectives outlined above.

You can take advantage of the technology by using different social media platforms, including Google Analytics and social media. Naturally, you can also use the audience data to have accurate factors that match the available information.

Moreover, creating a team of understandable and relatable personas is also vital, so it’s best to back that with user stories. Just bear in mind that you should create user stories focusing on the specific product feature. These stories should address the issues written in the MRD.

Main components and Sitemaps

You should also include the crucial components found in the document. These may consist of the product features, implementation, flowchart, and so on.

Aside from that, an effective PRD covers sitemaps that include vital information regarding the tentative product release. This will help the product development team gather necessary resources and prioritize the product accordingly.

Initial and future features

Here you should list the initial features that your product will have after being rolled out. Since PRD must be constantly updated, you should also allocate enough space to include future or additional features. This will help the tech team add all your desired features to the final product.

Non-Functional requirements

Non-functional requirements are a vital part of the Product Requirements Document. They help bridge the gap between what the product is supposed to do and how it is supposed to behave. This will serve as guidelines for developers to follow when building the product to ensure it will continue to perform optimally over time.

Wireframes

If your product is complex, with many features and functions, it won’t be easy to articulate its requirements with just written text. That’s where wireframes come in.

Wireframes are a visual representation of your product’s functions and user interface, including how each piece of the interface is supposed to look and behave. This will help developers craft the product according to your desired specifications.

Potential risks

Including the potential risks in the Product Requirements Document is essential to help developers estimate the impact of their proposed changes to the product.

By looking at the possible impact on the system, the developers can prioritize their changes and ensure that they are feasible within the context of the product as a whole. This helps make sure that the product continues to meet the needs of users and the business as a whole.

Future roadmap and iterations

Another element you should include in your PRD is the future roadmap and iterations. This will help the product designers and developers have a clear picture of the product itself and the end-users.

The iterations will also help the development team stay on track with their work.

Analytics

Analytics in PRD is essential for communicating the value of your product to its target audience. In the analytics section, you can include how the products will be used and what features customers will enjoy about them.

This is highly beneficial, especially if your product is designed for business users.

Best PRD example: analysis

There are different PRD examples and formats that you can follow. Here, we will analyze the most common and highly recommended Product Requirements Document example: our one-page PRD.

If you look at the one-page PRD examples online, you will notice that they are more well-designed and concise than the other formats. A smaller PRD is ideal, especially if it’s your company’s first one.

A one-page PRD saves you time and effort since you only need to include the essential information regarding the product. In addition, you could quickly introduce changes to such a document.

A one-page Product Requirements Document may look simple, but you still need to give it due attention to achieve the best results. Overall, this PRD template is ideal for keeping the context short and straightforward.

Conclusion

The importance of having a well-written, clear, and concise Product Requirement Document in today’s business world cannot be overstated. Such PRDs can help companies achieve their goals, reduce costs, and increase revenue and profit. Not to mention, they also help businesses avoid costly mistakes. So make sure to take it seriously and put some effort into writing your PRD. It will definitely be worth it.
