Requirement Types

The different types of requirements

Requirements in business analysis form the foundation for successful project delivery, guiding the development of solutions that meet business needs and stakeholder expectations. These requirements represent a detailed understanding of what a business or project aims to achieve and the necessary steps to get there.

The primary types of requirements are listed are product requirements, project requirements, and quality requirements. These requirements are explained below. The focus of this guide is on the product requirements.

Product Requirements

Business Requirements

These are high-level needs of the organization, addressing the goals, objectives, and desired outcomes. They often align with the strategic vision and provide the rationale for why a project is initiated. Examples:

  • Increase market share by 10% within the next fiscal year.
  • Improve customer satisfaction ratings by 20%.
  • Reduce operational costs by 15% through process automation.

Stakeholder Requirements

These requirements describe the needs and expectations of stakeholders. They include inputs from anyone who has an interest in or is affected by the project, ensuring that their needs are understood and addressed. Examples:

  • A customer needs an intuitive interface to place orders quickly.
  • The finance department requires detailed financial reporting capabilities.
  • Regulatory bodies require compliance with specific standards.

Solution Requirements

Solution requirements describe the characteristics of the solution that meets the business and stakeholder requirements. They are further divided into functional and non-functional requirements.

Functional Requirements

These define the specific behaviors, functions, and features a solution must have. They detail what the system should do and cover aspects such as operations, data handling, and business processes. Examples:

  • The system must allow users to create, update, and delete customer records.
  • The application should send email notifications to users when their orders are shipped.
  • The software should generate monthly financial reports.
Non-functional Requirements

These describe the quality attributes, system performance, usability, reliability, and other characteristics that a solution must possess. They often relate to the system’s environment and user experience. Examples:

  • The system should handle up to 10,000 concurrent users.
  • Page load time must not exceed 2 seconds.
  • The application must comply with GDPR regulations.

Transition Requirements

These requirements outline the conditions that must be met to transition from the current state to the future state. They include data migration, training, and change management needs essential for implementing the new solution. Examples:

  • Data migration from the legacy system to the new system.
  • Training programs for users to familiarize them with the new system.
  • Temporary interfaces to support parallel running of old and new systems.

Project Requirements

These requirements pertain to the constraints and conditions that the project itself must meet. They cover aspects such as project scope, budget, timelines, resources, and regulatory compliance. Examples:

  • Schedule: The project must be completed within 12 months.
  • Cost: The total project cost must not exceed $500,000.
  • Resources: Allocate a team of 5 developers, 2 testers, and 1 project manager.
  • Communication: Weekly status meetings with stakeholders are required.
  • Risks: Identify and mitigate potential risks through a risk assessment workshop at the start of each project phase.
  • Project Documentation: All project documentation must follow the organization’s standard templates and be stored in the document management system.

Quality Requirements

These specify the standards and criteria that the solution must meet to be considered acceptable. They ensure that the solution is effective and meets the agreed-upon quality standards. Examples:

  • Performance: The system should handle up to 10,000 concurrent users without performance degradation.
  • Reliability: The application must have an uptime of 99.9% over a 12-month period.
  • User Satisfaction: Achieve a user satisfaction score of at least 85% in post-launch surveys.
  • Defect Rate: Maintain a defect rate of less than 1% for critical functionalities during the first six months of operation.
  • Compliance: Ensure the product meets ISO 9001 standards for quality management.
