Automated Gantt Chart with Resource-Leveling and Over-allocation Alerts
Seed: TaskTable with ID, Name, Start, Duration, Resource; ResourceCapacity table; Formulas: StartOffset = MAX(PlannedStart, PrevEnd)ADVERTISEMENT - IN-ARTICLE
Implementation Guide
Build an Excel Gantt with dynamic start calculations, task dependencies, and simple resource-leveling heuristics. Use a tasks table with dependency IDs and compute earliest start via WORKDAY.INTL and MAX across predecessor end dates. Create a resource allocation matrix by mapping tasks to calendar days using formulas (e.g., use SEQUENCE to expand task days and SUMIFS to count resource demand per day). Compare demand to ResourceCapacity and flag over-allocation with conditional formatting. For leveling, implement a simple priority-based push (delay lower-priority tasks until capacity OK) using iterative recalculation or helper columns with cumulative capacity checks. Export resource-loaded timelines to a separate summary for stakeholder review and attach comments for manual adjustment. This is suitable for small-medium projects; for complex portfolios use a PM tool.
