Metrics & Health Scoring
Every process is measured across seven metric families, then those measurements roll up into six sub-scores, a single health score, and a risk tier. All of it is computed in code and is fully reproducible.
The seven metric families
Family 1: Structural
How complex the process is, and whether its shape is sound. Complexity is the strongest predictor of maintenance cost and defect rate.
| Metric | What it tells you |
|---|---|
| Stage Count, Transition Count | The raw size of the process graph |
| Cyclomatic Complexity | The number of independent paths through the process, the core complexity signal |
| Path Explosion Factor | How many distinct routes the process can take |
| Handoff Count, Handoff Ratio | How many times work changes hands, and how dense those handoffs are |
| Process Depth | The longest chain of stages from start to finish |
| Rework Risk Index | How prone the process is to loops and rework |
| Stage Fan-In Max, Fan-Out Max | The busiest convergence and divergence points |
| Cycle Detected | Whether the graph contains a cycle |
| Orphan Stages, Dead Stages | Stages that cannot be reached, and stages with no way out |
Family 2: SLA
Whether the process can meet its time commitments, and where the time goes.
| Metric | What it tells you |
|---|---|
| Overall SLA Days | The declared end-to-end target |
| SLA Slack | How much headroom exists against that target |
| Impossible SLA | Whether the target is unachievable given the stage durations |
| SLA Buffer Ratio | The buffer expressed as a fraction of the SLA |
| SLA Coverage Gap | The share of the process that has no SLA defined at all |
| SLA Hotspot Stage | The single stage that consumes the most time |
| SLA Concentration Index | How concentrated the time budget is in one stage |
| Average Stage Duration, SLA Variance | The central tendency and the spread of stage durations |
Family 3: Automation & Lean
How much of the process runs itself, and how much waste it carries.
| Metric | What it tells you |
|---|---|
| Value-Added Ratio | The share of stages that add value |
| Automation Rate | The share of stages that are automated |
| NVA Stage Count | The number of non-value-added stages |
| Waste Index | An aggregate measure of process waste |
| Automation Opportunity Score | Manual stages that are good candidates for automation |
| Manual-to-Auto Ratio | The balance of manual versus automated work |
Family 4: Governance
Whether the process has the controls a well-run operation needs.
| Metric | What it tells you |
|---|---|
| Entry Criteria Coverage, Completion Criteria Coverage | The share of stages with defined entry and exit conditions |
| Segregation of Duties Risk | Whether one actor holds conflicting responsibilities |
| Documentation Score | How well the stages are documented |
| Exception Handler Coverage | How much of the process has exception handling |
| Escalation Path Defined | Whether an escalation route exists |
| Approval Stage Count | How many approval gates the process contains |
Family 5: Actor & Persona
Who does the work, and how much key-person risk the process carries.
| Metric | What it tells you |
|---|---|
| Actor Concentration Index (HHI) | How concentrated the workload is across actors |
| Gini Coefficient | How unequally work is distributed |
| Single Point of Failure Risk | Whether one actor is indispensable |
| Bus Factor | How many actors could leave before the process stalls |
| Unique Actor Count, Max Actor Stage Load | How many actors are involved, and how loaded the busiest one is |
| Actor Diversity Index | How evenly work is spread |
| Cross-Functional Boundary Count | How many team or role boundaries the process crosses |
| Actor-Stage Breakdown | A per-actor map of stage assignments |
Family 6: Path Analysis
The routes work actually takes, from the fastest to the worst case.
| Metric | What it tells you |
|---|---|
| Happy Path (stage count and SLA) | The intended, shortest successful route |
| Critical Path (stage count and SLA) | The longest and slowest route |
| Shortest and Longest Path Stage Count | The bounds on route length |
| All Paths Count | The total number of distinct routes |
| Detour Ratio | The critical path length divided by the happy path length |
| SLA Amplification Factor | How much worse the critical-path SLA is than the happy path |
| Exception Path Count | How many rejection or error routes exist |
Family 7: Six Sigma (estimated)
An estimate of how capable the process is of meeting its target.
| Metric | What it tells you |
|---|---|
| Process Capability Index | The estimated ability of the process to stay within its SLA |
The health score
The seven families roll up into six sub-scores, each on a 0 to 100 scale, which combine into a single composite health score. The weighting is set per project and must sum to 1.0.
| Sub-score | What it rewards | Default weight |
|---|---|---|
| Structural | Low complexity, no cycles, no orphan or dead stages | 0.20 |
| SLA | Achievable SLAs, good coverage, no single-stage concentration | 0.25 |
| Automation | High automation, little waste | 0.15 |
| Governance | Criteria coverage, exception handling, no SoD risk | 0.20 |
| Actor | No single point of failure, healthy bus factor, even workload | 0.10 |
| Path | Short detours, low SLA amplification, little rework | 0.10 |
Risk tiers
The composite score maps to a risk tier, so a portfolio can be triaged at a glance. The tier boundaries are configurable. The defaults are:
| Tier | Health score |
|---|---|
| Low | 75 and above |
| Medium | 55 to 74 |
| High | 35 to 54 |
| Critical | below 35 |
Because both the weights and the tier boundaries are per-project settings, you can calibrate the model to your own definition of healthy. See Configuration & API.
