Features
Estimate-to-duration conversion Converts T-shirt size estimates (Small, Medium, Large, XL) to day-based durations with adjustments for team velocity and complexity.
Dependency-aware scheduling Orders tasks based on blocking relationships using Mermaid’s “after” syntax so dependent tasks automatically start after their prerequisites complete.
Milestone and critical path support Marks key deliverables as milestones and highlights the critical path using Mermaid’s crit modifier to show which tasks determine the minimum project duration.
Parallel workstream visualization Supports multiple concurrent workstreams with proper integration points, showing where parallel work converges and how it affects the overall timeline.
