Online trading platform PERT chart maps critical path across nine sequential and parallel tasks from requirements through deployment on AWS infrastructure. System Requirements Analysis (2 weeks) gates UI/UX Design and Database Design (3 weeks each), which feed into parallel Trading Engine development (5 weeks), User Account Module (3 weeks), and Security Integration (2 weeks). Testing (3 weeks) consolidates outputs, followed by Debugging (2 weeks) and one-week Deployment, establishing a 26-week critical path for go-live. This PERT model helps fintech teams identify scheduling bottlenecks, resource conflicts, and risk mitigation windows before launch. Fork this diagram on Diagrams.so to customize task durations, add AWS service dependencies, or integrate with your project management workflow. The Trading Engine and Security Integration tasks represent highest-risk dependencies for trading platform reliability.
