Original Problem

Microsoft Project resource work calculations fail for multi-resource tasks, causing inaccurate project timelines and budget estimates

Project managers using Microsoft Project experience a critical bug where work totals only calculate correctly for the first resource assigned to a task, while subsequent resources show incorrect aggregations. This causes cascading errors in project schedules, resource allocation planning, and budget forecasting, forcing teams to manually recalculate or use workarounds that consume hours of administrative time.
