Project management is the methodical approach of planning, organizing, and managing resources to successfully complete specific project goals and objectives.
Web-based tools can provide a structured environment to successfully handle the needs of a highly collaborative project, such as remote access of files, document version control, task and milestone tracking, and having a centralized location for team discussion.
Project management tools should be web-based, low cost, and require no programming or advanced skills. Comparing these features, as well as many others, will help to ensure your goals are met.
