How to Write Great Requirements (Tips and Examples)

Introduction

High-quality requirements are the backbone of successful software and systems development. Writing good requirements that are clear, complete, and well-structured not only improves communication among stakeholders but also minimizes 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.

Essential Characteristics of GREAT Requirements

Great requirements are essential for successful project development. They must be clear, actionable, and aligned with project goals. The following core characteristics ensure requirements are effective:

• Clarity – A requirement must be easily understood by all stakeholders. Ambiguity can cause misunderstandings and delays.
  • Example: Instead of saying “The system should be fast,” say, “The system shall process a user request within 3 seconds.”
• Conciseness – Great requirements are brief but comprehensive. They provide necessary details without unnecessary complexity.
  • Example: Rather than stating, “The system should allow the user to search for products by name, category, or price and provide suggestions,” say, “The system shall allow users to search products by name, category, or price.”
• Testability – Requirements must be testable to ensure they can be verified. Testable requirements outline clear conditions that can be validated.
  • Example: “The system shall support up to 1000 concurrent users without performance degradation” is testable through load testing.
• Feasibility – A requirement should be achievable within the project’s constraints, such as time, budget, and resources. Feasibility ensures practicality.
  • Example: “The system shall process 10,000 transactions per second” is feasible only if the architecture supports this load.

By incorporating these characteristics, clarity, conciseness, testability, and feasibility, requirements become actionable guidelines that drive project success, reduce risks, and ensure the final product meets its goals.

Tips for Writing Great Requirements

Writing high-quality requirements is crucial for project success. By following these key practices, you can ensure your requirements are clear, actionable, and aligned with project goals:

• Use Simple, Direct Language – Avoid complex jargon that may confuse stakeholders. Use clear, simple language that everyone, from developers to non-technical team members, can understand.
  • Example: Instead of “The system shall employ asynchronous processing for query responses,” say, “The system shall process queries in under 2 seconds.”
• Focus on What, Not How – Define what the system should do, not how it will do it. This focuses on desired outcomes, leaving technical implementation to design and development teams.
  • Example: “The system shall allow users to submit feedback through a web form” focuses on functionality, not the technical process.
• Quantify Where Possible – Specific, measurable outcomes make requirements clearer and easier to test.
  • Example: “The system shall load the homepage in under 3 seconds” provides a clear, testable benchmark.
• Eliminate Ambiguity – Avoid vague terms that can lead to misinterpretations and scope creep. Be specific in describing what is required.
  • Example: Instead of “The system should be easy to use,” say, “The system shall provide a step-by-step tutorial for first-time users to complete a transaction.”
• Involve Stakeholders Early – Engage stakeholders early in the process to ensure the system meets their needs and expectations. Regular feedback helps identify gaps before development starts.
  • Example: Hold regular meetings with business owners and end-users to review and refine requirements.

By applying these tips, using simple language, focusing on outcomes, quantifying requirements, eliminating ambiguity, and collaborating with stakeholders early, you’ll create well-defined, actionable requirements that lead to smoother project execution.

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:

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.”

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.).

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.

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 Writing Great Requirements?

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. This helps avoid common mistakes, such as vagueness or incomplete information, and ensures all critical aspects, like clarity, feasibility, and testability, are covered.
• Example Template Structure:
  • Requirement ID
  • Requirement Description (clear and measurable)
  • Type (Functional or Non-Functional)
  • Priority Level
  • Acceptance Criteria (for testability)
• Starting with a template ensures that teams cover all essential attributes and maintain quality across requirements documents.

Tools for Traceability and Alignment
