The Key Aspects of Product Requirement Documents

An important step when releasing a new software product, or any product for that matter, is the creation of a product requirements document. This is a type of documentation that includes all of the relevant information about a product. Product requirements documentation is often created in the early stages of development, so, to give developers leeway, product requirements documentation does not include how a product will eventually operate. Given the importance of product requirements documentation to the software development process, it is important to make sure it is handled correctly. This is where technical writers can help, as they know what specifically should be included in this kind of documentation, while also knowing the intricacies of software development.

The Essentials of Product Requirements Documents

Generally, product requirements documentation should include the overview of a product, its purpose, stakeholder identification, use cases, and its requirements. In essence, it is the document of record for a product. Other aspects of a product, such as the marketing, for example what the target demographic is, are handled through marketing requirements documents. Product requirement documents are used more to gain a better understanding of how to successfully build a product. This is done by shedding light on numerous factors, such as what is being made, how it will be used, what obstacles need to be overcome, and how it is being funded. 

Going into more detail, this type of documentation details the outline of the product being developed, from its purpose, features, functionalities, and behavior to possible consumer feedback and what third-party resources will be needed. The best way to go about creating a product requirements document is to compile all this information in an organized manner so that it is available during the development of a product. 

  • First, use cases should be included to outline how customers would respond to the product. Use cases would make it clear what the features and functions of a product are, and what situations are relevant to a customer for a certain feature or function. This way, what the product is trying to achieve with each functionality it has is clear. Plus, it gives engineers a greater understanding of what the goal of the product is by essentially outlining the purpose behind the product.
  • Next, a product requirements document must also outline the technical requirements that a product might have. These requirements range from the user experience of a product to give a general sense of how the product is intended to operate. In addition to UX design, other requirements such as what operating system it is intended to function in must also be included. 
  • Lastly, beyond the functional and technical aspects of a product, expectations of how users will interact with the product must also be accounted for. This is done through the inclusion of assumptions, constraints, and dependencies. Assumptions deal with how users might interact with the product, allowing you to predict how well the market responds to your product. Constraints and dependencies refer to possible limitations when developing a product, respectively budgetary or technical constraints and what the production process will depend on for your projects, such as API documentation or hardware needed for the product. By taking these three factors into account for your product requirements document, you can get a better scope of what the developmental process entails for your product, as well as correct any possible user experience issues. 

Who Writes the Product Requirement Documentation?

Looking at all this, a product requirements document necessitates a large amount of information regarding the product. The best way to go about creating this type of documentation for a software product is with a trained documentation writer. The skill of a documentation writer is that they can write concisely while also communicating all the important information needed. And with a clearly crafted product requirements document written by one of EDC’s documentation writers, your developers will have a clear understanding of the purpose and scope of whatever product you are currently working on.


The development of a new product can be chaotic given all the unknown variables at the start. The best way to reduce any potential mishaps is with a product requirements document. Product requirements documentation can be a big help in keeping track of a product during the production process in a clear step-by-step way. Whether for software products or manufactured goods, product requirements documentation gives you the advantage of a more efficient development time for your product, as all the goals and potential concerns or obstacles are laid out. The best way to produce such documentation is with trained technical and documentation writers. Essential Data Corporation’s documentation writers can provide such service.
