Key Functional Requirements for Website Development

Creating a Website Requirements Document

A Website Requirements Document (WRD) is essential as it serves as the project's foundational blueprint. This document should clearly outline functional requirements, client stories, and acceptance criteria. 'For example, individual stories should follow a specific format: 'As a [type of individual], I want to [perform some action] so that [some reason or benefit].'' Furthermore, acceptance criteria guarantee that each feature operates as expected from an end-consumer perspective, aligning with their expectations.

Furthermore, it is essential to provide a comprehensive summary of the core framework, its primary functions, purpose, and the technology stack it utilizes. Identifying and categorizing different user groups, such as administrators, end-users, and external stakeholders, adds clarity. The WRD should also break down the core system into its subsystems or modules, describing the functionality of each and how they interact with each other and external systems.

The document must also outline the roles and responsibilities of stakeholders, timelines, and necessary resources. Involving stakeholders during the preparation process to confirm needs and assumptions is essential. This guarantees that all involved have a common comprehension of project objectives and can avert problems that stem from inadequately defined specifications, ultimately resulting in a more successful project outcome.

Distinguishing Functional and Non-Functional Requirements

Functional specifications outline the particular actions and capabilities that an application must execute, including data processing, calculations, and interactions with individuals. These are the foundational elements that directly address the needs and objectives of the business. For example, in the creation of a central framework for public records management, functional specifications might involve individual authentication, data input, and report production.

Conversely, non-technical specifications emphasize the quality characteristics of the setup, including performance, security, and scalability. These criteria guarantee the setup functions efficiently in different circumstances and satisfies user expectations. Performance testing, for instance, is crucial to assess the speed, stability, and scalability of the application, ensuring it can manage high volumes of requests and data without compromising performance.

The distinction between functional and non-functional specifications is crucial for the successful delivery of any project. While functional specifications address what the platform should do, non-functional criteria ensure the platform operates effectively in practical situations. In a project like Armor, a portfolio website for the film industry, functional specifications would include features like video playback and portfolio management, whereas non-functional criteria would ensure the site loads swiftly, is secure, and can manage high traffic volumes.

To illustrate, consider the microservices and Apache Kafka implementation by Contentsquare for notification delivery. This configuration not only meets the practical need for timely alerts but also caters to non-functional criteria by ensuring the infrastructure is scalable and dependable under peak loads. Such a balanced approach to both types of needs leads to the development of robust and user-friendly systems.
