written by Areej Khan

Requirements are the specifications or features of a product or service that are deemed necessary by customers or stakeholders.

They are functional, non-functional, or both. Functional requirements define what a product or service should do, while non-functional requirements define how it should do it.

In this blog post, we will talk about the examples of requirements.

Examples of Requirements

1: Functional Requirements

These specify what the system should do. For example, in an e-commerce website, a functional requirement could be the ability to add items to a shopping cart.

2: Non-Functional Requirements

These outline the qualities or attributes the system must have. This could include performance criteria, like the website loading within 3 seconds.

3: User Stories

These are concise descriptions of a feature told from the user’s perspective. An example could be, “As a user, I want to reset my password easily.”

4: Use Cases

These describe the interactions between a system and an external entity. In a banking system, a use case could be withdrawing money from an ATM.

5: System Requirements

These define the hardware, software, and network requirements for the system to function. For instance, the system may need to run on Windows 10 or require a specific version of a database.

6: Business Rules

Rules that define or constrain some aspect of the business. For instance, a business rule for a subscription service could be that only registered users can access premium content.

7: Data Requirements

These specify the types and formats of data that need to be handled by the system. In a customer relationship management (CRM) system, data requirements could include storing customer names, emails, and purchase history.

8: Security Requirements

These outline the measures that need to be implemented to ensure the security of the system. For example, a banking application may require multi-factor authentication for user login.

9: Compliance Requirements

These are related to legal or industry standards that the system must adhere to. An example could be ensuring that an e-commerce site complies with data protection laws.

10: Performance Requirements

These specify the acceptable response times for various system functions. In a real-time trading system, a performance requirement could be that stock prices must be updated every second.
