name: process-mapper
description: Use when a BizOps lead, COO, or process-improvement owner needs to document an end-to-end business process (procurement, employee onboarding, incident handoff, customer-onboarding, claims adjudication) in BPMN-style notation, measure cycle times by stage, surface where work spends most of its time waiting vs. being worked, and quantify the gap between processing time and total elapsed time. Pairs Lean / Six Sigma / Theory-of-Constraints canon with deterministic stdlib-only Python tools to produce a process map, a ranked bottleneck list (with severity + root-cause hypothesis), and a cycle-time analysis (P50, P90, value-add ratio, Little's-Law throughput). Distinct from sales-pipeline, system-reliability (SLO), and strategic-OKR work — this is tactical process documentation for internal operations.

# process-mapper

BPMN-style business process documentation, bottleneck detection, and cycle-time analysis for internal-operations leaders.

## Purpose

Internal-operations work suffers from three recurring failure modes:

1. **Implicit process** — the steps exist only in tribal knowledge, so handoffs drop and onboarding takes weeks.
2. **Invisible waiting** — most of the elapsed time on any business process is queue / wait / approval time, not actual work; teams optimize the wrong stage.
3. **Local optimization** — Goldratt's Theory of Constraints is ignored; resources are added to non-constraint stages, gaining nothing.

This skill produces a documented process map, identifies where work waits, and points the constraint out by name with deterministic logic — not LLM intuition.

## When to use

- Documenting a new business process (procurement intake, vendor onboarding, employee onboarding, incident handoff, expense reimbursement, customer onboarding, claims adjudication).
- An existing process is "too slow" but nobody can name the bottleneck.
- Cycle time is being measured but value-add ratio is not — so the team can't tell whether the process is healthy or waste-heavy.
- Cross-functional handoffs are dropping work and root cause is unclear.

## Workflow

Five-step deterministic flow:

1. **Intake.** Capture the process as a JSON file with one entry per stage: `name`, `owner`, `type` (`value-add` | `wait` | `rework`), `duration_minutes_p50`, `duration_minutes_p90`. Use `assets/process_template.md` and its JSON skeleton.
2. **Map stages.** Run `process_documenter.py` to produce an ASCII swim-lane diagram + a normalized JSON artifact. The swim-lane separates lanes by owner so cross-functional handoffs become visible.
3. **Measure cycle time.** Run `cycle_time_analyzer.py` to compute total P50, total P90, value-add ratio (VA%), and a Little's-Law throughput estimate. Verdict: VA% > 25% = HEALTHY, 10–25% = TYPICAL, < 10% = WASTE-HEAVY.
4. **Detect bottlenecks.** Run `bottleneck_detector.py` with the appropriate `--profile` (saas / services / manufacturing / healthcare). Output is a ranked list with severity (CRITICAL / HIGH / MEDIUM), root-cause hypothesis, and one recommended action per finding.
5. **Recommend.** Pair the bottleneck list with the cycle-time verdict; recommend a single constraint-focused intervention per Goldratt's "subordinate everything to the constraint" rule. Don't recommend optimization of a non-constraint stage.

## Scripts

**`scripts/process_documenter.py`** — Reads a process JSON, validates it, and emits a text-based BPMN-style swim-lane diagram in Markdown (lanes by owner, stages annotated with type + duration). Also outputs a normalized JSON artifact for downstream tools. Stdlib only. `--sample` prints a 6-stage procurement-intake example.

**`scripts/bottleneck_detector.py`** — Applies three deterministic detection rules: (a) stage P50 > 2× mea
