# Critical Path Analyzer ## Overview The Critical Path Analyzer skill performs comprehensive Critical Path Method (CPM) analysis on project schedules. It calculates forward and backward passes to determine early/late dates, identifies float values, and highlights the critical path - the longest sequence of dependent activities that determines the minimum project duration. ## Capabilities ### Core CPM Calculations - Calculate forward pass (early start/finish dates) - Calculate backward pass (late start/finish dates) - Determine total float and free float - Identify critical path activities - Detect near-critical paths (activities with low float) ### Advanced Analysis - Perform what-if analysis for schedule compression - Calculate schedule risk exposure - Generate critical path reports and visualizations - Support multiple calendar assignments - Handle complex dependency relationships (FS, SS, FF, SF with lag/lead) ### Schedule Optimization - Identify crashing candidates based on cost-duration tradeoffs - Recommend fast-tracking opportunities - Calculate compression costs and benefits - Model resource-constrained critical path ## Usage ### Input Requirements - Activity list with unique identifiers - Activity durations - Predecessor/successor relationships with dependency types - Optional: Activity calendars - Optional: Resource assignments for resource-constrained analysis ### Output Deliverables - Critical path activity list - Float analysis report (total float, free ...
