# Software Requirements Specification Template (SRS)
## 1. Introduction
### 1.1 Purpose
The purpose of this document is to define and describe the functional and non-functional requirements for **[Product Name]**. This SRS serves as a definitive guide for the development, testing, and project management teams, and as a formal agreement between the development team and the project stakeholders. This document is intended to be a complete, unambiguous, and verifiable specification of the software system.
### 1.2 Document Conventions
All requirements are formatted as a clear, single statement. Keywords such as "shall," "must," and "will" indicate a mandatory requirement. Requirements are uniquely identified for tracking purposes.
### 1.3 Intended Audience and Reading Suggestions
This document is intended for:
* **Developers:** To understand what needs to be built. It is suggested they focus on Section 3.1 (Functional Requirements).
* **Testers:** To develop test cases and plans. They should focus on Sections 3.1 and 3.3 (Non-Functional Requirements).
* **Project Managers:** To manage scope, schedule, and resources. They should review all sections, particularly Section 2 (Overall Description).
* **Stakeholders:** To verify that the requirements align with their business needs.
### 1.4 Product Scope
**[Product Name]** is a **[brief, high-level description of the product, e.g., "web-based task management system"]** designed to **[state the primary business objective or value, e.g., "streamline workflow and improve team collaboration"]**. The system will provide **[list key features, e.g., task assignment, progress tracking, and notifications]**.

## 2. Overall Description
### 2.1 Product Perspective
**[Product Name]** is a **[e.g., standalone application, component of a larger system]**. It will interface with the following external systems/components:
* **[External System 1]**: [Description of interaction, e.g., "A third-party payment gateway for processing transactions."]
* **[External System 2]**: [Description of interaction, e.g., "A corporate LDAP server for user authentication."]
### 2.2 Product Functions
The major functions of **[Product Name]** are:
* User registration and login
* **[Function 1, e.g., "Create, read, update, and delete tasks"]**
* **[Function 2, e.g., "Assign tasks to team members"]**
* **[Function 3, e.g., "Provide real-time notifications for task status changes"]**
### 2.3 User Classes and Characteristics
| User Class | Description | Characteristics |
| :--- | :--- | :--- |
| **Administrator** | Manages system settings, users, and permissions. | Tech-savvy, requires full control, infrequent use. |
| **Team Member** | Creates, updates, and completes tasks. | Primary user, moderate technical skill, frequent use. |
| **Guest User** | Views public tasks or read-only information. | Limited access, no registration required, infrequent use. |
### 2.4 Operating Environment
The software will operate in the following environments:
* **Hardware**: A cloud-based server environment, **[e.g., AWS EC2, Google Cloud]**.
* **Operating System**: **[e.g., Linux, Windows Server]**.
* **Browsers**: The web interface must be compatible with the latest versions of Chrome, Firefox, Safari, and Edge.
### 2.5 Design and Implementation Constraints
* **Technology Stack**: The back-end must be built using **[e.g., Python with FastAPI, PostgeSQL]** and the front-end with **[e.g., Vue.js with Typescript, TailwindCSS]**.
* **Compliance**: The system must comply with **[e.g., GDPR, HIPAA]** regulations.
* **Performance**: All user actions must have a response time under **[e.g., 2 seconds]**.
### 2.6 Assumptions and Dependencies
* **Assumptions**: We assume that users have a reliable internet connection.
* **Dependencies**: The development of **[Product Name]** depends on the successful deployment of **[e.g., the corporate authentication service]**.
