Project Health Score: how it is calculated
The Project Health Score sums up a plan in one number from 0 to 100. It is calculated in your browser from your export.
| Part | Weight | 100 means |
|---|---|---|
| Adherence to plan | 35% | every task due in the last 30 days was done on time |
| Open tasks not overdue | 20% | no open task is past its due date |
| Milestone slip | 20% | open milestones are on their baseline (0 at an average slip of 60 days) |
| Tasks with due date and owner | 15% | every open task has both |
| On-time completions | 10% | every task finished in the last 30 days was on time |
Parts without data (for example slip with only one export) are left out and the others are re-weighted. The tool shows each part and which one pulls the score down most.
Reading the score
- 75–100 healthy
- 50–74 needs attention
- below 50 critical
The score is a conversation starter, not a verdict. Look at the next steps the tool suggests. Check your plan.
