Project management is all about planning, organization, and efficiency. Whether you’re managing a small team or a complex multi-phase project, having the right tools to visualize and analyze your workflow is essential. That’s where CPM-Net comes, client-side web application designed to help you master the Critical Path Method (CPM) with ease and for free.

Why Use the Critical Path Method?

The Critical Path Method is a proven technique for project scheduling that helps you:

• Improve Project Planning: Break down complex projects into manageable tasks and identify priorities.
• Strengthen Communication: Foster better communication among team members by visualizing dependencies and task sequences.
• Manage Resources Effectively: Allocate resources where they’re needed most and avoid bottlenecks.
• Minimize Delays: Detect risks early and adjust your schedule to keep your project on track.
• Control Costs: Tie costs to each task and monitor your budget more accurately.

What is CPM-Net?

CPM-Net is a browser-based project management tool that allows you to create, visualize, and analyze project schedules using the Critical Path Method. All your project data is processed locally, ensuring privacy and security. No server or installation is required—just open the app in your browser and get started.
