Lss Tools is a skill published by agensi that equips an AI agent with structured Lean Six Sigma (LSS) methodology at a depth comparable to Master Black Belt practice. Rather than relying on general process-improvement prompts, the skill enforces specific formulas and thresholds for metrics such as Process Capability (Cp, Cpk, Pp, Ppk), Gage R&R, and Overall Equipment Effectiveness (OEE). For statistical process control, it applies the Western Electric Rules to SPC charts and uses Anderson-Darling tests for normality assessment.

Waste identification is handled through structured TIMWOODS and DOWNTIME framework audits designed to quantify non-value-add activities. Root cause analysis follows established protocols including 5 Whys, Ishikawa diagrams, and Failure Mode and Effects Analysis (FMEA) with standardized Risk Priority Number (RPN) scoring. On the operational side, the skill guides implementation of 5S, Kanban, SMED, and Takt Time synchronization, and supports structured Gemba Walk protocols and Value Stream Mapping (VSM).

Outputs are structured reports that include data tables, severity calibrations, step-by-step implementation roadmaps, and prioritized action plans based on RPN or impact-effort matrices. The skill also distinguishes between Green Belt and Black Belt depth requirements, which helps route projects to the appropriate level of rigor. There are no environment variables or external service credentials required. The skill is a good fit when an agent needs defensible, methodology-grounded LSS guidance rather than generic process advice.

Use cases

  • Calculate and interpret Cp/Cpk and Pp/Ppk scores for a manufacturing process capability study
  • Run a TIMWOODS or DOWNTIME waste audit to quantify non-value-add activities on a production line
  • Conduct an FMEA with standardized RPN scoring to prioritize failure modes before a product launch
  • Apply Western Electric Rules to SPC chart data to detect statistically significant process signals
  • Design a 5S or Kanban implementation roadmap with step-by-step guidance
  • Facilitate a root cause analysis using 5 Whys and Ishikawa diagrams for a recurring defect

When to use it

  • The agent needs technically defensible LSS statistical formulas rather than generic advice
  • A project requires structured root cause analysis with FMEA, RPN scoring, or Ishikawa diagrams
  • Operational excellence guidance such as SMED, Takt Time, or VSM is needed in a workflow
  • The use case involves determining whether a problem warrants Green Belt or Black Belt escalation

When not to use it

  • The task is general data analytics or statistical modelling outside the LSS methodology domain
  • The skill cannot execute code, query databases, or read live process data — no tools are exposed
  • The project requires integration with external systems such as MES, ERP, or IoT data streams
  • The need is for project management or change management frameworks unrelated to Lean Six Sigma
