Maturity Guides

These reference guides explain the operational excellence tools behind the SEF maturity assessments: what each tool is, why it matters, how to put it in place, what each maturity level looks like, and the evidence an assessor looks for. Each guide includes a ready-to-use template and a 30-day starter plan.

Use them while scoring an assessment, or on their own when you are ready to fix one part of the operation.

Workplace and daily management

• 5S Workplace Organization: 5S is a method for organizing a work area so it stays clean, orderly, and easy to read.
• Total Productive Maintenance (TPM) and OEE: Total Productive Maintenance (TPM) is a way of running equipment so that breakdowns, slowdowns, and defects are designed out rather than repaired after the fact.
• Visual Management Systems: A Visual Management System (VMS) puts the right information in plain view, at the place where the work happens, so anyone can see what normal looks like, whether the area is on plan, and what to do next.
• Gemba and Tiered Daily Meetings: Gemba is Japanese for “the actual place.” In operations it means wherever the work happens: the line, the cell, the warehouse dock.
• Structured Problem Solving (A3): Structured problem solving is a disciplined, repeatable way to find the root cause of a problem and fix it so it stays fixed.
• Standard Work: Standard work is the current best known way to do a job, written down, trained, and followed, so the result is the same no matter who is on shift.

Quality

• Measurement Systems: Calibration and MSA: Every decision about quality rests on a measurement.
• Error Proofing: Poka-Yoke and Process FMEA: Error proofing is about stopping defects before they exist.
• Supplier Quality and Bottom-10 Supplier Development: Incoming inspection finds bad parts after you have paid for them, stored them, and sometimes built them into product.
• Process Control: CTQs, SPC, and Capability: Process control means measuring the few characteristics that matter most to the customer, measuring them inside the process where they are created, and reacting to statistical signals before a single defect is made.
• Customer Complaint Resolution (8D): A customer complaint resolution process is the standard path every complaint follows from the moment it arrives until it is closed: log it, protect the customer, find the root cause, fix it permanently, and prove the fix worked.
• Cost of Poor Quality (COPQ): Cost of Poor Quality (COPQ) is the money an operation loses because things are not done right the first time: scrap, rework, re-inspection, warranty, returns, credits, premium freight, and the engineering and management time spent chasing problems.

Flow and supply

• Theory of Constraints: Every plant has one resource that limits how much it can ship.
• Flow Design: VSM, SMED, and WIP: Flow design is the work of seeing how material and information actually move through the plant, then changing the layout, batch sizes, and changeovers so parts move from one value-adding step to the next without sitting and waiting.
• Pull Systems: Takt, Kanban, and Load Leveling: In a push system, a schedule built from a forecast tells each department what to make, and work is pushed forward whether or not the next step needs it.
• Supply Strategy: Kraljic Matrix and JIT: A supply strategy decides, for each group of purchased parts, how you will buy it, from whom, from where, and how it will reach the line.
• Resource Planning and Capacity: Resource planning answers one question with numbers instead of opinions: how many people and machines does this work need, and how does that compare to what we have? You take the demand for each type of work, multiply it by the time each step takes, and divide by the hours a person or machine actually gives you in a day.

People

• Safety Management and Near-Miss Reporting: A safety management system is the set of routines a plant uses to find hazards, control them, learn from what goes wrong, and check that the controls work.
• Skills Matrix and Cross Training: A skills matrix is a grid with people down one side, jobs or skills across the top, and a proficiency code in each cell.
• Improvement Recognition and Best Practice Transfer: This guide covers two habits that decide whether improvement spreads or stalls.
• Employee Satisfaction Measurement: Employee satisfaction measurement is how an operation finds out how its people feel about their work, and then acts on what it learns.

Commercial and performance

• Sales Channels: Configurators and Quote Hit Rate: The assessment scores one sales channel, whichever best fits the operation.
• Order Execution: Order execution is everything that happens between “the customer sent an order” and “the goods arrived and the invoice was right.” It covers order receipt, entry, checking, acknowledgment with a promised date, scheduling, production, shipping, transport, invoicing, and keeping the customer informed when something changes.
• Sales and Operations Planning (S&OP): S&OP is a monthly decision process.
• On Time Delivery (OTD): On Time Delivery (OTD) is the share of orders, or order lines, delivered on or before the date you committed to the customer.
• Cost Savings Register: A cost savings register is one controlled list of every cost reduction initiative in the operation.
• Planning Time Fences and Plan Stability: A planning time fence is an agreed point in time inside which the plan does not change without a deliberate decision.
