GANTTIC is a Web-based project management system for scheduling resources and projects. It provides a user-friendly graphical interface and interactive Gantt charts for real-time collaboration, and is intended as an alternative to MS Project. Most businesses use resource scheduling in their everyday life, but most common tools for it are still email, paper wall charts, notebooks, and spreadsheets. Specialized tools are expensive, complicated, and hard to implement. The software has a number of users from very different areas of life: design agencies, laboratories, churches, schools, manufacturers, service providers, equipment and car rentals, and construction and logistics companies scheduling their teams, equipment, and facilities on a daily basis.
