Checks an 8D discipline by discipline for missing content, human-error root causes, missing escape cause or action, late containment and dates out of order.
acceptance-sampling-plan-selector
Select and evaluate acceptance sampling plans for incoming, in-process and final inspection: ANSI/ASQ Z1.4 / ISO 2859-1 single sampling under normal inspection (code letter from lot size and inspection level I, II, III, S-1 to S-4; sample size, Ac and Re from AQL, following the table's arrows to the correct plan; 100% when n reaches the lot size; AQLs above 10 per 100 units), operating characteristic curves (Pa at any quality, producer's quality level, indifference point, LTPD, AOQ and AOQL, binomial or hypergeometric), plans designed from producer and consumer risk, and c = 0 zero-acceptance plans. Covers AQL choice by defect class, switching rules between normal, tightened and reduced inspection, when sampling is not appropriate, and random sampling.
approved-supplier-list-manager
Manage and audit an approved supplier list (ASL) / external provider register for ISO 9001 8.4.1, IATF 16949 8.4 and AS9100 8.4.1: supplier status (approved, conditional, probation, pending, disqualified), scope of approval by commodity and process, risk class, certification and expiry, re-evaluation intervals by risk, conditions with end dates, single-source contingency, approver and customer-directed sources. Audits the list for expired or expiring certificates, overdue re-evaluations, conditional or probation status past its decision date, high-risk suppliers without the required certification, single-source suppliers without backup and missing approvers, and checks purchase orders for suppliers that are off-list, disqualified or pending, or buying outside the approved scope. Covers ERP blocks, PO requirements, off-list and emergency purchases.
apqp-phase-planner
Plan and track Advanced Product Quality Planning (AIAG APQP 3rd edition, IATF 16949) for a new or changed automotive part: back-schedule the five phases (plan and define, product design, process design, product and process validation, launch and feedback) from the start-of-production date by program complexity, with overlap, PPAP lead and safe-launch period; list the deliverables and gate for each phase (DFMEA, DVP&R, feasibility, process flow, PFMEA, control plans, MSA, Ppk, run at rate, PPAP, safe launch, lessons learned); adjust for build-to-print suppliers; flag compressed timelines and late or untracked deliverables against a status list. Covers gate reviews, red/yellow/green status reporting, run at rate and safe-launch exit criteria.
as9100-gap-analyzer
Run an AS9100D / EN 9100:2018 gap analysis for aviation, space and defence suppliers on the requirements added to ISO 9001: on-time delivery and conformity focus, management representative, ethics and human-factors awareness, operational planning and operational risk management, configuration management, product safety, counterfeit-part prevention, special requirements, critical items and key characteristics, external provider register and flow-down, FOD prevention, tooling and NC program control, special process validation, first article inspection (AS9102), traceability, in-service data and nonconforming product control. Generates and scores a worksheet, grades missing core controls as major, and checks invalid n/a claims. Covers AS9101/AS9104, OASIS, AS9102 FAI forms, counterfeit standards (AS5553, AS6174, AS6081), NADCAP and the planned IA9100 transition.
audit-report-writer
Write internal, supplier and pre-certification audit reports with the content ISO 19011:2018 6.5 expects: audit objectives, scope, criteria with revisions, dates, team and auditees, method and sampling statement, specific strengths, findings table and three-part finding details (requirement, evidence, statement), conclusion on the degree of fulfilment of criteria, diverging opinions, follow-up deadlines and distribution. Builds a Markdown report from a JSON audit record, generates the conclusion from the findings (major / minor / none) and flags reports missing required content or findings without clause or evidence. Covers conclusion wording, closing meetings, response expectations and verifying corrective actions.
capa-effectiveness-checker
Verify whether a corrective action actually worked (ISO 9001 10.2.1 d, IATF 16949, 8D D6) with statistics instead of 'no complaints so far': before/after defect-rate comparison with an exact conditional binomial test for Poisson counts and a minimum practical reduction, zero-defect demonstration size (n = ln(1-C)/ln(1-p), rule of three) with progress so far, and exact Clopper-Pearson upper bounds on the post-action defect rate. Returns effective, not yet demonstrated (with the units still needed) or not effective. Covers setting effectiveness criteria when the CAPA is opened, choosing the window by problem frequency, leading indicators for rare failures (Cpk, SPC stability, error-proofing checks, LPA), and traps such as volume changes, detection changes and containment masking.
capa-plan-writer
Write and review corrective and preventive action (CAPA) plans that meet ISO 9001 10.2 (also IATF 16949 10.2, AS9100, ISO 13485 8.5.2): correction and containment, verified root causes for occurrence and escape, corrective actions linked to each cause and ranked by strength (eliminate > error-proof > automate/detect > standardise > train > remind), owners and dates, measurable effectiveness checks, extension to similar products and sites, and updates to PFMEA, control plans, procedures and risks. Reviews a CAPA for 'operator error' or symptom root causes, correction-only actions, training-only actions, unverified causes, unlinked actions and missing effectiveness criteria; reports a CAPA log by stage, age, owner, overdue and stuck actions, and closed-too-fast CAPAs.
control-plan-writer
Write and review control plans (AIAG Control Plan, IATF 16949 8.5.1.1 and Annex A) for prototype, pre-launch and production phases: operation, equipment, product and process characteristics, special characteristic class (CC/SC), specification, measurement technique, sample size and frequency, control method (SPC, 100% inspection, error-proofing, check sheet) and reaction plans that stop, contain suspect product since the last good check, correct, verify and record. Drafts control plan rows from a PFMEA (product rows from detection controls, process rows from prevention controls, sampling parsed from the control text), and checks a control plan for missing specs, methods, sampling or reaction plans, weak controls on special characteristics, reaction plans without containment and disagreement with the PFMEA.
design-of-experiments-planner
Plan and analyse two-level designed experiments (DOE) for manufacturing process improvement: choose screening, characterisation or optimisation designs; generate full and fractional factorial designs (2^(k-p) with standard minimum-aberration generators up to 8 factors) with replicates, centre points and randomised run order; print the defining relation, resolution and alias structure; analyse results with effects for main effects and two-factor interactions, t-tests from replicates or Lenth's method for unreplicated designs, curvature tests from centre points, the coded model and recommended settings. Covers resolution III/IV/V, factor and level selection, sample size for a target effect, half-normal thinking, aliases and fold-overs, interaction interpretation and confirmation runs.
document-control-system-designer
Design and audit a document control system for ISO 9001:2015 clause 7.5 (and IATF 16949 / AS9100 / ISO 13485 variants): document hierarchy, document vs record, numbering scheme with separate revision, master list / document register fields, review and approval workflow, change control, point-of-use control, obsolete document withdrawal, external documents (standards, customer drawings), electronic systems (SharePoint, eQMS) and record retention schedules. Designs a numbering scheme and validates existing IDs (duplicates, revision letters in IDs, next free number), and audits a document register for duplicate or multiple approved revisions, missing approvals, obsolete copies at points of use, overdue reviews, self-approval, missing revisions, records without retention and stale external documents.
five-whys-analysis-facilitator
Facilitate and check 5 Why root cause analysis for quality problems, NCRs, CAPAs and 8D D4: factual problem statement without cause, why chains that stay on facts, branching when an answer has two causes, separate occurrence, escape (non-detection) and systemic legs, stopping at a controllable process or system cause rather than a person, the reverse 'therefore' test, and verifying causes by switching them on and off, reproducing them or with data. Checks a written 5 Why for causes in the problem statement, chains ending in blame or human error, too-short or too-long chains, circular answers, causes outside the organization's control, double causes and vague answers, and prints the therefore test for every leg. Includes worked examples from machining, assembly and office processes.
gage-rr-msa-analyzer
Run and interpret measurement system analysis (AIAG MSA 4th edition, IATF 16949 7.1.5.1.1): crossed variable Gage R&R by ANOVA (variance components, operator x part interaction test with pooling at p > 0.25, %contribution, %study variation, %tolerance, ndc) and by the Average and Range worksheet method (EV, AV, PV, GRR, range-chart check), and attribute agreement analysis for go/no-go and visual inspection (within-appraiser agreement, effectiveness, miss rate, false alarm rate, Cohen's kappa vs the reference, system agreement). Applies the 10% / 30% and ndc >= 5 criteria, says whether repeatability or reproducibility dominates, and covers study design, %tolerance vs %study variation, bias, linearity, stability, destructive tests and how to improve gauges and inspectors.
green-belt-exam-tutor
Tutor candidates for Six Sigma Green Belt certification exams (ASQ CSSGB, IASSC and company programmes) across fundamentals and the DMAIC domains: practice quizzes drawn from an original question bank with worked explanations (sigma and DPMO, lean wastes, takt, RTY, Kano, charters, SIPOC, CTQs, COPQ, MSA and ndc, Cp and Cpk, data types, d2 estimates, test selection, p-values, error types, correlation and regression, fractional factorials, resolution, effects, poka-yoke, control chart limits, run rules, reaction plans, handover), reproducible quizzes by seed with shuffled options, grading with per-domain scores and weak areas, an answer-key mode, a study plan and a formula sheet.
hypothesis-test-selector
Choose and run the right hypothesis test for Six Sigma Analyze and quality decisions: test roadmap by Y type (continuous, proportion, count) and X type (target, two groups, paired, several groups, continuous) covering 1-sample, 2-sample Welch and paired t-tests, F and Levene tests for variances, one-way ANOVA, Mann-Whitney, Kruskal-Wallis, 2-proportion, McNemar, chi-square of association, Poisson rate tests, correlation, regression and logistic regression, with assumptions, non-parametric alternatives and Minitab menu paths.

iatf-16949-requirement-checker
Check an automotive supplier against IATF 16949:2016 requirements that add to ISO 9001: customer-specific requirements (CSR matrix), product safety, corporate responsibility, contingency plans, MSA and laboratory requirements, competence and auditor qualification, record retention and engineering specification review, special characteristics and product approval (PPAP), supplier selection and monitoring, control plans, set-up verification, TPM, temporary process-control changes, rework and repair, manufacturing process and product audits, problem solving, error-proofing and warranty management. Generates a worksheet with the 26 required documented processes flagged and one CSR row per customer, scores it, and grades gaps as major (missing documented process, CSRs not met, missing core controls) or minor. Covers core tools (APQP, PPAP, FMEA, SPC, MSA), IATF Rules grading and CSR management.
incoming-inspection-plan-writer
Write risk-based incoming (receiving) inspection plans for purchased parts and materials: classify characteristics as critical, major or minor, set the inspection level from supplier grade and lot history (first article and 100% for new parts or suppliers, tightened for grade C/D or repeated rejects, normal c = 0 sampling from LTPD per class, skip-lot for proven grade A suppliers, dock-to-stock with periodic audit), compute c = 0 sample sizes capped at the lot size, and apply switching rules; flags grade D suppliers without an open SCAR and reduced inspection without certificates. Covers certificate (CoC/CoA) review, lot-homogeneous characteristics, what to check at receiving, the plan document format and shifting effort upstream to supplier SPC and source inspection.
internal-audit-schedule-planner
Plan a risk-based ISO 9001 internal audit programme (clause 9.2, ISO 19011): audit frequency per process from risk, previous results and changes; a load-balanced 12-month calendar that schedules overdue and never-audited processes first; auditor assignment that never puts an auditor in their own department; clause coverage check so every clause family 4-10 is audited each cycle; audit types (process, clause, product, trail, layered); auditor competence, independence and pool sizing; programme records and tracking.
iso-9001-certification-roadmap-planner
Plan the route to ISO 9001 certification: phased project timeline from gap analysis through context, processes, documentation, training, a 3-month records period, a full internal audit cycle and management review to stage 1, stage 2, nonconformity closure and certificate, scaled by headcount and starting maturity; estimated audit days from the IAF MD 5 table with surveillance and recertification dates over the 3-year cycle; target-date feasibility check; certification body selection (accreditation, IAF MLA, sector codes, 3-year cost); project governance, budget and timeline risks.
iso-9001-clause-explainer
Explain any ISO 9001:2015 clause (4.1 to 10.3, including the 2024 climate-change amendment) in plain language: its intent, what it actually requires, what compliance looks like in the user's type of organization, the evidence an auditor will ask for, common nonconformities and related clauses. Looks up clauses by number or keyword, maps ISO 9001:2008 clauses to their 2015 equivalents (management representative, preventive action, quality manual), and explains core concepts: Harmonized Structure and PDCA, process approach, risk-based thinking, documented information (maintain vs retain), correction vs corrective action, verification vs validation, shall/should/may.
iso-9001-gap-analyzer
Run an ISO 9001:2015 gap analysis (including the 2024 climate-change amendment) against an organization's current quality system: generate a clause-by-clause worksheet of auditable requirements, record status and evidence, score readiness by clause and section, grade each gap as a likely major or minor nonconformity, flag invalid exclusions (n/a outside 7.1.5, 8.3, 8.5.3, 8.5.5), 'met' with no evidence and missing mandatory documented information, and turn the gaps into an ordered closure plan with owners and evidence of closure.
iso-9001-quality-manual-writer
Write or modernise an ISO 9001:2015 quality manual that describes the company's own QMS: scope with products, services and sites, justified requirements not applicable (only 7.1.5, 8.3, 8.5.3, 8.5.5), process map and interaction table with owners, inputs, outputs, KPIs and documents, quality policy, roles and authorities, pointers to procedures and registers, and a clause cross-reference. Generates a Markdown manual draft from a JSON company profile and reviews an existing manual for missing scope, unjustified or invalid exclusions, missing policy or process interaction, ISO 9001:2008 leftovers (management representative, preventive action, six mandatory procedures), text that parrots 'the organization shall', placeholders and the 2024 climate-change amendment.
iso-audit-checklist-generator
Generate ISO 9001 internal or supplier audit checklists for a process (leadership, sales, design, purchasing, production, inspection, warehouse, maintenance, HR, quality) or for chosen clauses: open 'show me' questions with the evidence to sample, the clauses asked in every process audit (risks, objectives, competence, documented information, monitoring, corrective action), and optional turtle-diagram questions (inputs, outputs, with what, with whom, how, measures). Outputs a Markdown table or a CSV to fill in with results. Covers how to use a checklist: process approach, audit trails, sample sizes, questioning techniques, recording conforming evidence, nonconformities and OFIs.
layered-process-audit-designer
Design and run layered process audits (LPA, AIAG CQI-8, IATF 16949 and OEM requirements such as GM BIQS): layer structure (supervisors daily, managers weekly, plant leadership monthly), short risk-based yes/no question cards drawn from PFMEA, control plan reaction plans, special characteristics and recent complaints, rotation so higher layers see every area, workload per person, on-the-spot correction and escalation. Builds a rotating multi-week LPA calendar with workload from a people list, and analyses LPA results for compliance by area, layer and question, repeat failures that need corrective action, failures not corrected, layer gaps that show weak layer-1 audits, and stale always-pass questions to rotate.
manufacturing-cpk-capability-calculator
Calculate and interpret process capability for manufacturing characteristics: Cp, Cpk, Pp, Ppk and Cpm with within-subgroup sigma (R-bar/d2, pooled S, MR-bar/1.128) and overall sigma, one-sided specifications, expected ppm within and overall vs observed ppm, a Bissell confidence interval for Cpk, Anderson-Darling normality test, and the percentile method for non-normal data. Explains off-centre processes, Ppk below Cpk from shifts and drift, wide intervals from small samples, and requirements such as PPAP Ppk 1.67, ongoing Cpk 1.33 and customer-specific thresholds; covers data prerequisites (MSA, stability, 100+ values) and non-normal causes and methods.
manufacturing-dmaic-charter-writer
Write and review Six Sigma DMAIC project charters for manufacturing improvement: business case with money and strategic link, problem statement with what, where, when and how much but no cause or solution, SMART goal statement from baseline to target by a date, customer CTQ, primary metric with operational definition and a counter-balance metric, scope in and out, champion, process owner, belt and team, phase dates with tollgates. Checks charters for causes or solutions in the problem statement, missing magnitude or time frame, unmeasurable goals, targets no better than the baseline, missing scope, sponsor or owner, phase dates out of order or projects too long; estimates cost of poor quality (scrap, rework, escapes, appraisal), savings at the goal and payback. Covers SIPOC, DMAIC tollgate questions, scoping and why projects fail.
manufacturing-spc-chart-builder
Build statistical process control charts for manufacturing: choose the chart from the data (I-MR, X-bar/R, X-bar/S for measurements; p, np, c, u for defectives and defects with constant or varying sample size), compute centre lines and control limits with the standard constants, flag points beyond the limits, recompute Phase I limits after special causes are removed, report the within-subgroup sigma for capability, and render the chart as a standalone SVG with optional specification lines. Covers rational subgrouping, Phase I vs Phase II, prerequisites (MSA, sampling frequency, reaction plan), reading the chart, control vs capability and common mistakes such as spec limits used as control limits, mixed-cavity subgroups and tampering.
minitab-analysis-interpreter
Interpret Minitab output for quality and Six Sigma work: read pasted Session window or report text and extract the key numbers from Process Capability reports (Cp, Cpk, Pp, Ppk, observed vs expected PPM), Gage R&R ANOVA (%Study Var, %Tolerance, ndc, Part*Operator interaction, dominant component), regression (coefficients, P-values, VIF, S, R-sq, R-sq(adj), R-sq(pred)), one-way ANOVA, two-sample and paired t-tests (P-value, confidence interval), Anderson-Darling normality tests and DOE coded coefficients; flag what needs attention (Cpk below 1.33, Ppk well below Cpk, PPM far above prediction, GRR above 10 or 30 percent, ndc below 5, over-fitted models, insignificant terms, multicollinearity) and state the conclusion in plain words. Covers how to read each output and the most common misreadings.
ncr-nonconformance-report-writer
Write and check nonconformance reports (NCRs) for ISO 9001 8.7, IATF 16949 8.7 and AS9100: requirement vs actual description with drawing revision and measured values, part, lot and quantities, detection point, containment across machine, WIP, stock, transit, customer and supplier, disposition (rework, repair, use-as-is, scrap, return to supplier, regrade) with MRB authority, concessions and deviation permits, re-inspection after rework, and when to escalate to CAPA or 8D. Checks NCRs for missing requirement or extent, incomplete containment for late detection, use-as-is or repair without concession, rework without re-inspection and vague descriptions; trends an NCR log with Pareto by defect, part, supplier or cost, repeat part/defect combinations, aging open NCRs, escape rate and unrecorded cost.
pareto-defect-analyzer
Analyse defect, scrap, rework and complaint data with Pareto charts: counts, quantities or cost-weighted Paretos with cumulative percentages and the vital few up to 80%, grouping of small categories into Other, stratified Paretos by line, shift, supplier or part, before/after comparison by period, and an SVG chart with the cumulative line. Warns when Other outgrows the top category, when the Pareto is flat (stratify differently), and when the count and cost Paretos disagree. Covers choosing count vs cost vs severity, rates vs counts, one-off events vs chronic losses, defect code design and the cost-of-defect model.
ppap-submission-package-builder
Build and check Production Part Approval Process (AIAG PPAP 4th edition, IATF 16949 8.3.4.4) submissions: the 18 PPAP elements (design records, engineering changes, customer engineering approval, DFMEA, process flow, PFMEA, control plan, MSA, dimensional results, material and performance tests, initial process studies, lab documentation, appearance approval, samples, master sample, checking aids, CSR records, PSW), what to submit vs retain at levels 1-5, which elements are still missing, and when a PPAP is triggered by changes. Checks the Part Submission Warrant for identification, weight, results declarations, IMDS, signature and the initial process study acceptance rules (Ppk > 1.67 accepted, 1.33-1.67 customer review, < 1.33 not accepted, 100 readings in 25 subgroups, stability).
process-fmea-builder
Build and review process FMEAs with the AIAG-VDA FMEA Handbook (2019) method used under IATF 16949: seven steps, structure from the process flow diagram, failure chains (effect, failure mode, cause at the 4M work-element level), prevention and detection controls, severity / occurrence / detection ratings, Action Priority (H/M/L) instead of RPN, and actions with owners and re-rating. Rates a PFMEA CSV with the full AP table plus legacy RPN, sorts by priority, and flags AP-H rows without action, severity 9-10 without controls, invalid ratings, detection 1-3 claimed for visual inspection, occurrence 1-2 without prevention, unmarked special characteristics and actions without owners. Covers the link to the control plan, review triggers and common audit findings.
qms-audit-finding-writer
Write audit nonconformities and observations that auditees accept and can act on: the three-part structure (requirement with clause, objective re-checkable evidence with record IDs, dates and sample size, one-sentence nonconformity statement), fact-only wording without opinions, names or prescribed solutions, and correct grading as major, minor or opportunity for improvement (ISO/IEC 17021-1, IATF 16949 and AS9100 practice). Lints findings for missing requirement or evidence, advice graded as a nonconformity, opinion words, named individuals, prescribed solutions, likely grade mismatches (single lapse graded major, total absence graded minor), vague quantities, missing sample sizes and overlong statements.
qms-procedure-writer
Write and review ISO 9001 quality management system procedures and work instructions that people can follow and auditors can verify: purpose, scope, RACI responsibilities, definitions, numbered actor-action-timing steps, records with retention, references and revision history. Generates a procedure in Markdown from a JSON process description (with a RACI table built from the steps) and lints existing procedures for missing sections, vague wording (as needed, periodically, promptly, etc.), passive steps with no actor, should/may ambiguity, records without retention, overlong steps and missing time limits. Covers when to write a procedure vs a work instruction vs a form, and common manufacturing QMS procedures (document control, contract review, purchasing, calibration, nonconforming product, corrective action, internal audit, management review).
quality-fishbone-diagram-builder
Build and use Ishikawa (fishbone, cause-and-effect) diagrams for quality problems: 6M bones (Man, Machine, Method, Material, Measurement, Environment) plus 8M, service (4S/8P) and IT variants, prompt questions to fill empty bones, causes written as conditions rather than solutions or blame, sub-causes, status marking (untested, likely, verified, ruled out) and a verification plan that turns candidate causes into a proven root cause. Generates a text or Mermaid fishbone from a CSV cause list, normalises category names, and flags empty bones, solution-shaped causes, blame, duplicates and diagrams with no candidate selected.
quality-policy-objectives-drafter
Draft and check an ISO 9001:2015 quality policy (5.2) and quality objectives register (6.2). Writes a 50-120 word policy in the company's own words that covers the mandatory commitments (satisfy applicable requirements, continual improvement, framework for objectives) and checks existing policies for missing commitments, generic slogans (world-class, zero defects), numeric targets and length. Builds measurable objectives cascaded to functions with baseline, target, due date, owner, resources and evaluation method, and checks a register for unmeasurable targets, missing owners, overdue or unplanned objectives, targets no better than the baseline and functions without objectives. Includes a KPI library by function.
six-sigma-dpmo-calculator
Calculate Six Sigma defect metrics for manufacturing and transactional processes: DPU, DPO, DPMO, yield per opportunity, Poisson and observed first-time yield, sigma level with or without the 1.5 sigma shift, conversions between DPMO, yield and sigma level, rolled throughput yield across process steps with normalised yield and the hidden factory, and a sigma table. Covers how to count defect opportunities consistently, ppm defective vs DPMO, DPU vs DPO, FTY vs RTY, and the relation between sigma level and Cpk.
supplier-audit-questionnaire-builder
Build and score supplier audit and self-assessment questionnaires for approving new suppliers or re-evaluating existing ones (ISO 9001 8.4, IATF 16949 8.4.2, AS9100): questions chosen by supplier type (machining, electronics, chemical, distributor, service) and risk level, weighted sections (management system, contract review, sub-tier control, process control, inspection and measurement, nonconforming product and CAPA, traceability and delivery, commodity specifics such as ESD, MSL, IPC-A-610, batch records, CoA, authorized-channel sourcing), knockout questions, evidence to request, and a 0-3 scoring scale. Scores completed questionnaires by section and overall, applies knockouts and returns approved, conditional (with improvement plan) or not approved. Covers supplier risk classes and on-site vs self-assessment.
supplier-corrective-action-request-writer
Write supplier corrective action requests (SCARs) and evaluate the supplier's response: when to issue a SCAR, a problem statement with requirement, actual result, quantity and evidence, impact and cost recovery, response deadlines (containment 24-48 hours including stock at the supplier, in transit and at the customer with a clean point; root cause in about 10 working days; closure with effectiveness in 30-60 days). Checks the request for missing facts and loose deadlines, and checks the response for incomplete containment, missing or blame-based occurrence and escape causes, correction- or training-only actions, missing verification, effectiveness, PFMEA and control plan updates or read-across, and late steps; returns accept, accept with comments or reject.
supplier-development-plan-writer
Prioritise and plan supplier development (IATF 16949 8.4.2.5, ISO 9001 8.4): rank suppliers by spend share, risk, performance gap and single-source exposure; decide develop, replace or monitor; and draft a dated 90-day development plan per selected supplier with kick-off, joint assessment, signed action plan, levers matched to each gap (process control, MSA, capability, problem solving, delivery and planning, APQP/PPAP, quality system, special processes, sub-tier control), on-site verification and close-out, plus PPM, OTD and score targets. Covers the develop-or-replace matrix, signs a development effort will or will not work, governance and records.
supplier-quality-scorecard-builder
Build supplier quality scorecards for ISO 9001 8.4 and IATF 16949 8.4.2.4 supplier monitoring: PPM from received and rejected quantities, on-time delivery, responsiveness to corrective action requests, scored 0-100 with configurable weights, a weighted total, A/B/C/D grades, trend against previous periods, and flags for grade D suppliers, two-period declines and PPM above target without a SCAR. Covers KPI definitions (PPM, incidents, OTD window, OTIF, premium freight, disruptions), normalising for low volumes and commodities, grade-to-action rules, the automotive escalation ladder (SCAR, executive escalation, controlled shipping levels 1 and 2, new-business hold, resourcing) and avoiding distorted scores.
western-electric-rules-checker
Detect special-cause patterns on control charts with the Western Electric rules (1 point beyond 3 sigma, 2 of 3 beyond 2 sigma, 4 of 5 beyond 1 sigma, 8 in a row on one side) and optionally the Nelson rules (9 in a row, 6-point trends, 14 alternating points, 15 points hugging the centre, 8 points avoiding the centre). Works from given centre and sigma, from control limits, or from a Phase I baseline; merges overlapping hits into one signal per pattern and names the likely manufacturing cause (setting change, new lot, tool wear, tampering, stratification, mixture). Covers zones, false-alarm rates and average run length, which rules to use in Phase I vs Phase II and on range or attribute charts, autocorrelation, and how to respond to a signal without tampering.
