Business Software Requirements – Editor’s note: This article was originally published in 2014. It was so popular that we updated it in 2019 with more details.
Once the big software requirements gathering questions are answered and you’ve hired a software shop, all the development team needs to do is start asking smaller questions. These questions are just as important as the big questions and will address dozens (or even hundreds) of specific requirements for your project.
Business Software Requirements
When it comes to language, developers tend to be literal minded. Code is written in clear software “languages” and each piece of code means only one thing. Conversely, the language we use to communicate with customers can be full of ambiguity. Let’s go back to our widget manufacturer example from Part I and imagine a company looking for a better way to manage its inventory.

Are they addressing an immediate, operational need for a better way to physically count their inventory and account for locations? Is the cost of order fulfillment high, requiring increased efficiency? Or, do they find themselves canceling orders because they don’t have a reliable record of what’s in stock? Do they need a way to predict what stock customers will request? Or are they speaking holistically and completely revamping their inventory systems to meet business goals?
It is not easy after all. To avoid the potential pitfalls of ambiguity and achieve success, it is imperative that your custom software development partner fully understands each individual project requirement, no matter how general or trivial that requirement may seem. That’s where effective requirements gathering techniques come into play.
Let’s look at a simple, standard requirement for any web application: a user login form. While listing their requirements, the client may ask for a “User Login Form”. This sounds simple, but underneath this request lies the potential for a lot of complexity. Let’s imagine that a developer creates a user login form and launches it.
The day after the application is launched, the client discovers that users are sharing credentials, allowing simultaneous access to restricted areas. Since the guarantee to prevent the use of accounts from two different places was not in the scope of the project (only the “authentication form”), the developer did not make it. They add it.

The next day, another problem arises. Users who forget their username or password do not know how to retrieve them. So the developer goes back and configures the username and password recovery features. Soon, however, the client realized that users must agree to terms and conditions before logging in for the first time. And then, system administrators need a way to customize access for users with internal company email addresses. and so on.
This example illustrates the complexity of requirements gathering. What the client thought was a single requirement was actually made up of many, interrelated requirements. A developer who wants the customer to succeed should not take requirements at face value, but ask the “who”, “what”, “where”, “when”, “why” and “how” questions.
Before building a digital solution to a business challenge, developers must understand the analog process in detail. A developer should also understand the challenges a business faces without such a facility. How is business doing today and how will this feature reduce the severity of the current challenge?
Customer may use the phrase “login form” to describe complex functionality, such as charging users a subscription fee for premium content. While Step 1 should help bridge any gaps in understanding, a technique for clarifying when to gather requirements might be to follow one of the following scripts:
Steps For A Better Software Requirements Gathering Process
“Sometimes when a customer says ___, he really means ___. Other times he may be referring to ___. What does that mean to you?
“Suppose we build a feature that does exactly XYZ, then what? What would that mean for the ___ challenge you mentioned in step 1?”
Developers need time to consider the impact of a new feature on the rest of the system. It’s easy to imagine a “happy path” to the new imperative, but the devil is in the details. Corner cases are rare circumstances where a feature does not work as expected and can be difficult to anticipate. Additional features must be made early to identify and discuss in detail the need to isolate corner cases.
Now you are ready to write the requirement. To capture relevant information, we recommend using a Mad Libs-style process called User Stories. A basic blank user story looks something like this:
How To Prepare App Requirements Document
“As a (user type), I want this feature to enable me to (task) so that I can (result in business value).”
Writing the “perfect” user story is not the point. Instead, think of user stories as bookmarks for conversations from steps 1-4. When it comes to things like requirements gathering techniques, the Agile manifesto emphasizes over-documentation, and it’s important not to get caught up in it. Instead, work with your team to document and save in your project management system. Then, move on.
The final step is to write a “how to perform” or “HTD” for each user story. Think of it as a written contract that includes a definition of fact.
HTDs outline the steps that will demonstrate to both the developer and the customer that the requirement has been met to the customer’s satisfaction. This show-don’t-tell method removes any remaining ambiguity, showing that the requirement works and explaining how it works. This way, there are no unpleasant surprises during implementation.

Even though the written specifications may not have changed, expectations of how these requirements will be met may be. If testing is not done at regular intervals, both parties may be in for an unpleasant surprise when the project is delivered.

Not all projects are winners. According to the Project Management Institute’s 2021 survey, inadequate requirements gathering and poor initial planning are among the main reasons many projects fail. So what can you do to make your project a winner? Start with a written business requirements document or BRD.
From this article, you will learn all about business requirements documents and get well-structured templates for a complete picture of the topic. Also check out our video on technical documentation in software development.
Before explaining how to write business requirements, let’s see how they differ from other types of requirements used in product management. This will help you see the global landscape of software documentation. It is worth noting that while separate categories of requirements may have common high-level objectives, this does not mean that they are interchangeable.
How To Become A Successful Business Analyst
According to BABOK (Business Analysis Body of Knowledge), currently the main reference source for business analysis, project requirements can be classified as follows.
Business requirements define the strategic trajectory of the project. This includes high-level project requirements that describe the overall business objective from the company’s perspective. The objective may be to increase profit margins or gain a larger market share. Depending on the scope, business requirements can be as simple as a few lines describing key business needs or a very complex set of goals across different business areas.
User requirements, also called stakeholder requirements, are statements that describe what value a particular solution is expected to provide to individual groups of users (customers, managers, etc.). These statements are often seen as a bridge between business requirements and specific system requirements.
Product requirements, also called solution requirements, are specific descriptions of the capabilities and qualities that a solution must have to meet user and business needs. They come with a certain level of detail to enable effective solution development and implementation. Product requirements fall into two categories:

Transition requirements are additional requirements that define the capabilities and conditions that a system must have in order to move an organization from its current state to its future state. They are temporary in nature, as they are used only during the transition phase. Such requirements may address issues related to data conversion or staff training.
Whatever the case and type of requirements, you need to define them as clearly as possible for the project to be successful.
A business requirements document (BRD) is a formal description of the business goals and expectations that an organization has regarding a particular project or business solution. It usually explains the reasons for starting the project, the set of business values and the purpose behind undertaking the project etc. The main idea of BRD is to clarify all business aspects of the project.
In the project life cycle, the business requirements document is one of the first steps. Includes a comprehensive view of the work to be completed. Generally, writing BRDs is the responsibility of business analysts, but there may be other experts involved in documenting business requirements. It includes project development team, product manager, business partners, senior manager, content
