Functional specification documents help create a product that users love. Learn what they are and how to join them!

Reducing risk is one of the most valuable things you can do on a project. The reduction of potentially costly problems or wasted effort results in a more streamlined design and development process. It also puts smiles on the faces of stakeholders and improves efficiency.

One way to reduce UX design headaches and foster better communication among your team is to create and use a functional specification document that serves as the single source of truth for a future project.
In this article, we’ll look at what a functional specification document is, why your team needs one, and how to create one.
Functional specification documents may seem cohesive, but a plan is to an architect what a plan is to the developer. It is usually provided along with other important files such as designer and developer images, CSS, design specifications and prototyping tools such as the prototype itself.
Automatic Generation Of A Software Requirements Specification (srs) Document
Functional specification documents are designed to tell developers what to build and why. Defined features describe how it will solve certain problems for users. Issues identified during the requirements gathering process, when you research your user profiles to confirm issues identified by the customer.
Depending on the company, the type and size of the project, and the client, functional specification documents may include one or more of the following elements:
The Approvals category will contain all features that have been approved by other stakeholders such as customers and product managers.
Nailing Your Software Requirements Documentation
The project scope will include a summary of key requirements: problems and solutions, and features that meet those requirements.
In terms of risks and assumptions, you will talk about the risks your project faces in terms of technical, time and money. Basically anything that can affect the functional design of the product.
A use case, or user problem, is an overview of the situation a user finds themselves in, i.e. the problem they have and how your product helps them solve it. You can also divide a feature into user scenarios and user flows using diagrams that describe each stage of the process of using a feature.
How To Write A Product Requirements Document (prd)
This is where you define what your product needs to do to help the user and meet your business goals, i.e. the required features.
This is where you include everything you propose to create to solve a problem (sitemaps, user flows, etc.).
Here you will see in detail the steps required to configure the future product. An example of this might be the need to create a user account.
Technical Specification Templates
Non-functional properties will define the general characteristics of the system. This section describes the product’s appearance, usability, sensitivity level, learning curve, and how long it will take to complete certain tasks.
This is where you define how the product will handle user input errors, and how the user behaves when they make an “error” instead of some other flow.
This is where you will specify how the ticket will be handled during development, as well as how to resolve any errors or problems that arise later.
Interface Technical Specification Template
Functional specification documents are primarily for developers, those who code your product to deliver the final solution to the user.
This means that your functional specification document should be read by everyone on your team, including the customer. It’s important for everyone to refer to this common source of truth throughout the product development cycle. It will be the glue that holds the project together.
This is especially useful for developers, as the simple language and diagrams make it easier to visualize software solutions before starting to code. Developers who begin programming this undocumented software system often run into problems with their code later.
Project Specification Template
So who writes functional specification documents? The role of a specific person or team may vary from company to company or organization, but is rarely written by just one person.
Typically, the product manager creates specification documents in collaboration with others such as UXers, customers, and other project stakeholders. You can sit down with members of other departments to write functional specification documents, get early buy-in, and make sure everything is on track.
Imagine starting to write a novel without planning. Is it possible? Maybe Success? You don’t think your life is like that. So imagine writing a piece of software without planning! Your functional specification documents serve as a roadmap for developers.

Development is hard enough, and without writing a line of code on the edge of your seat, it can be a bug or a mistake, with no structure or plan. In fact, most developers worth their salt won’t code before starting.
Joel Spolsky argues that not having a functional specification document means spending more time coding and producing less efficient and poor-quality code, which makes it harder to debug later. You also run the risk of ending up with a generic product that doesn’t fit its purpose.
Another reason to use functional specification documents before developing products or product features is to avoid poor design by committee meeting. That’s because functional specification documents are a way to include everyone and remove personal assumptions about product features so you can create features that solve real problems for your users.
Product Technical Specification Template
Once you define the requirements gathering process and functional specifications, you will find that everything goes much more smoothly. Everyone knows what they’re doing, and they work from a few sources of truth in succession between different departments.
Defining roles for each participant and all stakeholders, along with expectations from each department, means there are no gray areas when it comes to getting things done. No stone is left unturned in the functional specification document, meaning that anyone can do their own thing and ensure that no detail is left unturned.
Finally, having a functional specification document that clearly defines all the features of your solution for the user will avoid the dreaded feature.
Product Design Technical Specification Template
Functional specification documents prevent design changes, unexpected pitfalls, or changes in direction initiated by the customer or other stakeholders. That is, if you have done a good functional specification document, it already comprehensively answers the user’s question and provides a suitable solution. The rest is unnecessary.
Gather requirements by listening to the customer and conducting rigorous user research. You will write a lot of information at this stage. You can use a claim collection tool to manage all of this information.
After completing your prototype, you can begin the first phase of user testing to test your customer’s initial assumptions, including user flow, user mental models, and how they use the software. Most importantly, you can test whether these traits are actually useful for your main characters.
How To Write Software Design Documents: With Examples
If testing confirms your assumptions, you begin writing a functional specification document so that your developers can code the final product.
Do not attempt to create a functional specification document in isolation. Instead, if possible, try to include one person from each department involved in product development, including the customer.
First, it helps to use good version control software. Most functional specification documents are written in Microsoft Word, but Google Docs allows for better version control, which is critical to product development.
Product Requirements Template
Often, developers complain about confusing version control in Word documents and not being able to see when and where a particular change was made. It’s also easier to keep document changes in sync in the cloud using Google Docs.
Often, your functional specification document will be written in complex language. That’s because it’s easier to discuss features and design solutions for a product in open language—and review those ideas—than doing it in code.
This is the main reason functional specification documents exist in the first place. Simple language and diagrams make everything clear from the start. Developers who start out without this documentation in hand often find this to be the case
