Business Requirements Document

Business Requirement Name

Governing Project: Project Name

Deliverable Identifier: PRQ-1


Introduction

Purpose

💡

Provide a short and clear description of the one specific set of Business Requirement or Requirements. Ideally one Business Requirement has one BRD under my management.

Conventions

💡

Detail the non-proprietary conventions, methodologies, techniques, frameworks, practices, or other know-how deemed worth mentioning. The manager alone determines what is worth mentioning, based on their judgment of the readiness and capability gap between the Intended Audience and the content of this document.

Terms and Definitions

💡

List all Terms and their Definitions specific to this BRD. Include references to any external Terms and Definitions used, ensuring they are consolidated here for clarity.

Intended Audience

Name Role





Suggested Prior Knowledge

💡

Compile a list of links, books, training materials, and other knowledge sources recommended for review before interpreting this BRD.

Overall Description

Project

💡

Since the BRD is generally accessed by a broader audience than the Project Charter, provide a concise summary of the project’s scope and purpose. This allows the BRD to be distributed for further analysis, design, or execution work while safeguarding information deemed more sensitive, which is intentionally excluded from this document.

Product (or Service)

💡

Complete this after finishing Section 3. Summarize the product’s key features and the main functions it provides or enables for users. Keep it high-level—details go in Section 3. Organize the content clearly, making it accessible to any BRD reader. Visuals like top-level data flow diagrams or class diagrams can help illustrate how major requirement groups connect.

Actors

💡

Refer or list and describe all the actors relevant for the currently covered Business Requirements

Operating Conditions

💡

Give a clear and detailed description of the environment where the business requirements outlined in this document will be met.


Don’t forget to cover any environmental factors that could impact or shape how the solutions are expected to perform.

Constraints and Limitations

💡

Outline any constraints or limitations that will shape or restrict the options available to developers. These might include:

  • Regulatory or corporate policies.
  • Hardware constraints, such as timing, performance, or memory limits.
  • Required integrations with other systems or applications.
  • Specific technologies, tools, or databases that must be used.
  • Dual operations running in parallel.
  • Language or localization requirements.
  • Communication protocols that must be adhered to.
  • Security requirements.
  • Established design conventions or programming standards, especially if the delivered solution will be maintained by the customer’s organization.


Keep it precise and actionable—this is where you define the playing field for the project.

User Guidance Materials

💡

List the user documentation to be delivered (e.g., manuals, online help, tutorials). Include any required formats or standards, if known.

Assumptions

💡

List factors believed to be true but not confirmed, which may impact the requirements. Examples include planned use of third-party components, expected development environments, or presumed constraints. If these prove false or change, the project may be affected.

Dependencies

💡

Identify external elements the project relies on, such as reusable software components from other projects or third-party services. Note: Skip dependencies already documented in other project materials (e.g., vision document or project plan).

Risks

💡

Highlight potential issues stemming from incorrect assumptions or unmet dependencies. Specify how these risks could influence the project and its outcomes.

Features

💡

This section outlines how to structure the functional requirements for the product, typically grouped by system features—key services the product delivers. Alternatively, you can organize them by use case, operational mode, user type, object category, functional hierarchy, or any logical combination. Choose the approach that best aligns with the project’s needs and clarity.

«Feature/Component Name»

Summary

💡

Provide a clear, high-level summary of this feature or component. Explain its purpose, the problem it addresses, and its role in the overall project or product.

Key Interactions

💡

List any user actions, triggers, or operational inputs and the corresponding responses, behaviors, or outputs expected from the feature. Highlight interactions that define how the feature functions within its environment or system.

Detailed Functional Requirements

💡

Clearly define what this feature or component must accomplish, focusing on measurable and verifiable deliverables. Include:

  • Specific capabilities or actions the feature must support.
  • Expected behaviors in edge cases or error scenarios.
  • Any conditions or constraints (e.g., “must comply with [X] standard”).

Each requirement must be uniquely tagged (e.g., REQ-01, REQ-02).

Assumptions

💡

Factors presumed to remain constant or true for the feature to function correctly.

Preconditions

💡

Conditions that must be met before the feature is operational.

Postconditions

💡

The expected state or outcomes once the feature’s processes are complete.

Dependencies

💡

Identify external or internal factors (e.g., systems, tools, third-party components) necessary for implementation.

Risks

💡

Highlight risks specific to the feature and potential mitigation strategies.

Use Cases

💡

Level of granularity is subject to Project and Business Requirement complexity. Ensure that there shall be no surprises to any party involved in this BRD.

ID and Name
Actors and Roles
Trigger Events
Normal Flow
Alternative Flow
Exceptions or Error Handling
Priority and Frequency of Use
Special Requirements or Constraints

External Interface Requirements

💡

Include only the relevant items and omit the rest. The level of detail should align with the engagement’s complexity and the clarity required in the contract to avoid Client-Vendor misunderstandings.

User Interface

Software Interface (API)

Hardware Requirements

Communications Interfaces

Reporting Requirements

Other Nonfunctional Requirements

💡

Only concrete quantifiable or provable traits may be described. No "asap" bullshit, and immature nonsense like that.

Availability

Conceptual Integrity

Flexibility

Interoperability

Maintainability

Manageability

Performance

Reliability

Reusability

Scalability

Security

Supportability

Testability

User Experience / Usability

Other Requirements

💡

Legal compliance, standards, and others may be included here.
