System Requirements Document for warehouse-inventory

1. Introduction

The WAREHOUSE INVENTORY application is designed as a professional warehouse-management dashboard exclusively for use on laptop and desktop computers. It aims to provide clarity, precision, and efficient data handling for warehouse staff, focusing on landscape orientation and effective use of horizontal space. The application is not intended for mobile devices and will prioritize usability, simple navigation, efficient data entry, and comprehensive statistics, graphs, and reports.

2. System Overview

The WAREHOUSE INVENTORY application is a desktop-only solution tailored for warehouse staff to manage inventory efficiently. It features a persistent left sidebar for navigation and a main content area for displaying dashboards, calendars, stock information, and reports. The application supports multiple screen resolutions, with a primary design resolution of 1366 × 768, and is optimized for larger screens such as 1440 × 900 and 1920 × 1080. The application emphasizes clarity and usability, adhering to Dieter Rams' design principles of functional clarity and simplicity.

2a. Product Interpretation and Delivery Boundary

The application is strictly for desktop and laptop use, with no mobile application or mobile-specific navigation features. It requires application-owned identity for access to protected warehouse data and operations. The application includes a public entry surface, identity access surfaces, and operational pages for warehouse management tasks. The backend persists warehouse records, calendar data, operational tables, charts, and reports across sessions.
