How to Write Great Requirements (Tips and Examples)

How to Write Great Requirements (Tips and Examples)

Introduction

High-quality requirements are the backbone of successful software and systems development. As highlighted in Visure’s “Improve and Write Better Requirements,” effective requirements play a crucial role in reducing misunderstandings, mitigating project risks, and aligning all team members toward shared goals. Requirements that are clear, complete, and well-structured not only improve communication among stakeholders but also minimize costly errors and rework later in the development process.

By focusing on improving the quality of requirements, teams can ensure that all project phases—from planning to testing—are more streamlined and efficient. Well-crafted requirements establish a strong foundation for building products that meet customer needs and regulatory standards while keeping projects on time and within budget. Ultimately, high-quality requirements are essential for delivering a product that meets user expectations, enhancing the overall value and success of the project.

What Are Requirements?

Requirements are detailed specifications that outline what a system must accomplish, setting the foundation for successful project development. Well-defined requirements are essential for alignment across teams and ensure that all project phases move forward efficiently.

High-quality requirements must exhibit attributes like clarity and completeness. These qualities prevent ambiguity, ensuring that requirements are understandable, actionable, and measurable for all stakeholders.

Requirements typically fall into two main categories:

  1. Functional Requirements: These specify what the system should do, focusing on actions or functions essential for end-users. Functional requirements should be clear and detailed to avoid misinterpretation. For example, a functional requirement for an e-commerce website could be, “The system shall allow users to add items to a shopping cart.” This clarity ensures developers understand the precise actions needed to meet user expectations.
  2. Non-Functional Requirements: These outline the system’s performance, reliability, usability, and other quality attributes. Unlike functional requirements, they address “how well” the system performs, rather than “what” it does. For instance, “The system shall load each page in under 2 seconds” is a non-functional requirement. Attributes like clarity and completeness are equally important here, as these requirements often shape the system’s overall user experience.

High-quality requirements—whether functional or non-functional—are critical because they define the scope of work with precision, minimizing costly rework, delays, and misunderstandings. They create a common understanding among stakeholders, ensuring the final product meets both technical and user needs.

4 Major Attributes of "GREAT" Requirements

Great requirements are the cornerstone of successful project development. There are several key characteristics that ensure requirements are effective, clear, and actionable. These core attributes are essential for aligning teams and ensuring that the final product meets expectations.

  1. Clarity: A high-quality requirement must be clear and easily understood by all stakeholders. Ambiguity can lead to misunderstandings, project delays, and costly rework. For example, instead of stating “The system should be fast,” a clearer requirement would be, “The system shall process a user request within 3 seconds.”
  2. Conciseness: Great requirements are brief yet comprehensive. They provide just enough detail to convey the necessary information without being overly wordy or complex. Overly detailed requirements can cause confusion and detract from the focus. For instance, rather than saying “The system should allow the user to search for products by name, category, or price and provide suggestions,” a more concise version would be, “The system shall allow users to search products by name, category, or price.”
  3. Testability: Requirements must be testable to ensure that they can be verified once implemented. A testable requirement outlines clear conditions that can be checked through validation or testing. For example, “The system shall support up to 1000 concurrent users without performance degradation” is testable because performance can be evaluated under load conditions.
  4. Feasibility: A great requirement must be realistic and achievable within the project’s constraints, such as time, budget, and resources. Feasibility ensures that the requirement is not only desirable but also practical. For example, “The system shall be able to process 10,000 transactions per second” is feasible only if the system’s architecture can handle such a load.

By incorporating these essential attributes—clarity, conciseness, testability, and feasibility—requirements become more than just documentation; they become actionable guidelines that drive successful outcomes. These characteristics help prevent ambiguity, reduce risk, and ensure that the final product meets the desired goals.

Do's and Don'ts Of Writing Requirements

Writing high-quality requirements is essential for the success of any project. By following a few key practices, you can ensure that your requirements are clear, actionable, and aligned with project goals. Based on insights from “Improve and Write Better Requirements” and “Do’s and Don’ts of Writing Requirements”, here are actionable tips to improve your requirement-writing process:

  1. Use Simple, Direct Language
    • Avoid complex, technical jargon that can confuse stakeholders and lead to misinterpretations. The goal is to write in a language that everyone, from developers to non-technical stakeholders, can understand.
    • Example: Instead of saying, “The system shall employ asynchronous processing for query responses,” say, “The system shall process queries in less than 2 seconds.” This avoids unnecessary complexity and keeps the requirement accessible to all.
  2. Focus on What, Not How
    • Great requirements define what the system should do, not how it will do it. This keeps the focus on the desired outcomes, leaving the technical implementation details to the design and development teams.
    • Example: “The system shall allow users to submit feedback through a web form” is a clear functional requirement. Instead of describing the system’s technical architecture, focus on the outcome or feature that needs to be delivered.
  3. Quantify Where Possible
    • A requirement is more valuable when it includes specific, measurable outcomes. By quantifying your requirements, you can ensure clarity and testability. 
    • Example: Instead of saying, “The system shall be fast,” say, “The system shall load the homepage in under 3 seconds.” This provides a clear, testable benchmark for developers and testers.
  4. Eliminate Ambiguity
    • Ambiguous language can lead to varying interpretations, resulting in scope creep and misaligned deliverables. Be specific about what is required and avoid vague terms such as “user-friendly” or “simple.”
    • Example: Instead of “The system should be easy to use,” write, “The system shall provide a step-by-step tutorial for first-time users to complete a transaction.”
  5. Involve Stakeholders Early
    • Collaboration with stakeholders early in the requirements-gathering phase ensures that the system meets user needs and reduces the likelihood of misaligned expectations. Stakeholders should provide input on functionality, constraints, and goals.
    • Example: Hold regular meetings with business owners and end-users to review requirements and gather feedback. This helps identify gaps or misunderstandings before development begins.

By following these tips—using simple language, focusing on outcomes, quantifying requirements, eliminating ambiguity, and involving stakeholders early—you can ensure that your requirements are not only well-defined but also actionable, leading to smoother project execution and successful results.

Common Mistakes To Avoid When Writing Great Requirements

When writing requirements, it’s easy to make mistakes that can lead to project delays, miscommunication, or even failure. Based on insights from “Do’s and Don’ts of Writing Requirements”, here are some common mistakes and practical solutions to avoid them:

  1. Vagueness
    • Mistake: Writing vague requirements can lead to confusion, missed expectations, and costly rework. Requirements such as “The system should be fast” or “The system should be user-friendly” leave room for interpretation and can result in misalignment between stakeholders and development teams.
    • Solution: Be specific and measurable. Clear, detailed requirements set the direction and provide measurable benchmarks for success. For example, instead of saying, “The system should be fast,” specify, “The system shall load the homepage in under 3 seconds.” This creates a concrete target for developers to work towards and testers to verify.
    • Example: From “Improve and Write Better Requirements”, avoid phrases like “quick response times” and instead state “response times under 2 seconds for 90% of user queries.”
  2. Mixing Requirements with Technical Design
    • Mistake: Another common pitfall is mixing requirements with technical solutions or design details. While requirements define what needs to be done, design specifies how it will be achieved. Writing a requirement that includes technical details, such as, “The database should be implemented using PostgreSQL,” blends the two and restricts flexibility during the design phase.
    • Solution: Keep requirements focused on what the system must do and leave technical solutions for the design phase. For example, “The system shall store user data securely” focuses on the requirement, while the technical design can determine how this will be accomplished (e.g., using encryption or specific database choices).
    • Example: A requirement should be: “The system shall allow users to save their preferences for future sessions.” The technical design can then decide the best way to store this data (e.g., using a cloud database, local storage, etc.).
  3. Lack of Stakeholder Input
    • Mistake: Not involving stakeholders early enough in the requirements-gathering process can lead to missed needs, misunderstandings, or mismatched expectations. If stakeholders are not consulted, there’s a risk that the requirements may not align with user needs or business goals.
    • Solution: Involve all relevant stakeholders early and often. Collaborate with business owners, end-users, and technical teams to ensure that the requirements are complete, accurate, and feasible. Regular feedback from stakeholders will help ensure the project stays on track.
    • Example: Hold workshops or interviews with users and business owners to gather feedback on key features, and validate requirements through frequent check-ins to avoid misunderstandings.
  4. Overloading Requirements
    • Mistake: Overloading a requirement with unnecessary details or too many conditions can cause confusion and make it harder for development teams to focus on what’s essential. For instance, a requirement like “The system shall allow users to perform basic tasks, such as searching for products, adding items to a cart, viewing reviews, and tracking order status, all while providing a responsive interface” can be overly complex and difficult to implement.
    • Solution: Break down complex requirements into smaller, more manageable pieces. Focus on the core functionality and eliminate extraneous details that can be addressed in later stages. Keeping requirements concise helps maintain clarity and ensures that developers can implement features without being overwhelmed by too many conditions.
    • Example: Instead of combining multiple functions into one requirement, split them into individual, focused requirements such as “The system shall allow users to search for products” and “The system shall allow users to add items to a cart.”

By avoiding these common mistakes—vagueness, mixing requirements with design, lack of stakeholder input, and overloading requirements—you can create clear, actionable, and achievable requirements that guide the development process and lead to successful outcomes.

How to Use Templates and Tools for Requirement Writing

Using templates and tools can significantly enhance the quality, consistency, and efficiency of requirement writing. Well-structured templates help ensure uniformity across requirements, while tools provide traceability, facilitate reviews, and support collaboration. As highlighted in “Improve and Write Better Requirements,” leveraging these resources streamlines the requirements process, making it easier to manage changes and align with stakeholders.

Templates for Consistency

  • Templates standardize the structure of requirements, ensuring that each requirement document is clear, concise, and follows a consistent format.
