leave-approve System Requirements Document

Introduction

The "leave-approve" project is designed to facilitate the management of leave requests and approvals within an organization. This document outlines the system requirements necessary to implement and operate the leave-approve system effectively.

System Overview

The leave-approve system is intended to streamline the process of requesting, approving, and tracking employee leave within an organization. It will provide a user-friendly interface for employees to submit leave requests and for managers to review and approve these requests. The system will ensure that all leave transactions are recorded and accessible for future reference, enhancing organizational efficiency and transparency.

Functional Requirements

• As an Employee, I should be able to submit a leave request specifying the type of leave, start date, and end date.
• As an Employee, I should be able to view the status of my leave requests.
• As a Manager, I should be able to view all leave requests submitted by my team members.
• As a Manager, I should be able to approve or reject leave requests.
• As an Administrator, I should be able to configure leave types and policies.
• As an Administrator, I should be able to generate reports on leave usage and trends.

User Personas

• Employee: A regular user who submits leave requests and checks their status.
• Manager: A user responsible for approving or rejecting leave requests from their team.
• Administrator: A user with the ability to configure system settings and generate reports.

Core User Flows

• Employee submits leave request -> Manager reviews request -> Manager approves/rejects request -> Employee receives notification of decision.
• Administrator configures leave types -> Employees submit requests -> Managers approve/reject requests -> Reports are generated by Administrator.

Visuals Colors and Theme

• primary: #1A73E8 (a deep blue for a professional look)
• primary_light: #E8F0FE (a light blue for hover states)
• secondary: #FF7043 (a warm coral for emphasis)
• accent: #F4B400 (a vibrant yellow for call-to-action buttons)
• highlight: #FBBC05 (a bright amber for notifications)
• bg: #FFFFFF (a clean white background)
• surface: rgba(250, 250, 250, 0.8) (a subtle light grey for panels)
• text: #202124 (a dark grey for primary text)
• text_muted: #5F6368 (a muted grey for secondary text)
• border: rgba(218, 220, 224, 0.2) (a light grey for borders)

Signature Design Concept

The homepage of the leave-approve system will feature an interactive calendar interface. Users can click on dates to initiate leave requests or view existing ones. The calendar will have smooth animations powered by framer-motion, allowing users to drag and drop to adjust leave dates dynamically. Hovering over dates will reveal a tooltip with leave details, and clicking on a date will expand it into a detailed view with options to submit or modify requests. This interactive calendar will provide an engaging and intuitive user experience.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, providing a layered depth effect as users scroll through the page. Decorative elements such as atmospheric blobs and distant shapes will move at different speeds, creating a dynamic and visually rich first impression. Internal pages, such as dashboards and settings, will adopt a "static" model to prioritize clarity and ease of use.

Non-Functional Requirements

• The system must support concurrent users without performance degradation.
• The system should ensure data security and privacy in compliance with organizational policies.
• The system must be accessible on both desktop and mobile devices.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local orchestration: Docker and docker-compose

Assumptions and Constraints

• The system will be deployed within the organization's existing IT infrastructure.
• User authentication will be handled by the organization's existing identity management system.
• The system will operate in the Singapore timezone (SGT).

Glossary

• Leave Request: An application submitted by an employee to take leave from work.
