Improve Processes

Improve Processes

Process-siren's job is semantic fidelity. Faithful conversion of a flawed process encodes the flaws with false precision. Use this skill when the source process needs improvement before — or alongside — Mermaid conversion.

When to Apply

Apply before converting when the source shows ANY of:

• Abstract verbs with no concrete action ("handle", "manage", "ensure")
• Conditions that cannot be evaluated by an AI agent ("when appropriate", "if needed")
• Missing entry or exit conditions
• Undefined actors ("we", "the system", "someone")
• Steps that do not change state (pure description, no action)
• No feedback loop or error path

Frameworks (Reference Only)

These frameworks share one principle — a process must be deterministic, auditable, and actor-owned.

Lean (Ohno) — eliminate steps that produce no state change; apply 5 Whys to trace ambiguity to its root

Six Sigma / DMAIC (Smith) — Define outcome, Measure current state, Analyze gap, Improve, Control recurrence

BPR (Hammer) — radical question: "If we started from scratch, what would this look like?"

Design Thinking (IDEO/Brown) — Empathize with the agent executing the process; design for their decision points

Systems Thinking (Senge) — identify feedback loops and side effects before encoding structure

Theory of Constraints (Goldratt) — find the bottleneck step; simplify around it before adding branches

Antifragility (Taleb) — prefer processes that improve under stress over processes that merely tolerate it

Excellence Checklist

Before converting, verify the source process satisfies:

• Clarity — no interpretive gaps; every term has one meaning
• Determinism — same input produces same output, independent of executor
• Minimal cognitive load — relies on structure, not memory
• Explicit feedback loops — error paths and retry conditions stated
• Measurable outcomes — each terminal state has an observable signal
• Visible constraints — blockers and preconditions named, not implied
• Ownership — every step names the actor
• Edge case coverage — at least one failure scenario is handled
• Teachable in 5 minutes — a novice can follow it cold
• Auditable — execution can be traced and verified after the fact
