Glossary

Terms and abbreviations of manufacturing excellence

When we talk about TPM, OEE, 5S or the Ishikawa diagram, we mean what's described below. The glossary is focused on the manufacturing context.

TPM & maintenance

# TPM Total Productive Maintenance: A comprehensive approach to maintenance in which operators take responsibility for basic machine care and maintenance shifts from reactive to preventive and predictive. The goal is zero unplanned downtime and maximizing OEE.
# TPM&M Total Productive Maintenance & Management: An extension of TPM with a management layer - it connects autonomous maintenance, planning, analytics and the action plan into one platform. The iDomino brand for an advanced version of TPM focused on the whole value stream.

# AMS Audit Management Software: Software for running internal audits digitally, inspecting products and performing LPA / 5S checks with an escalation workflow, AI report generation and a link to the action plan.
# LPA Layered Process Audit: A layered process audit - short, frequent checks of standard compliance at the workstation, performed across management levels (foreman, production manager, director). A standard in automotive (IATF 16949).

# APS / Action Plan Action Plan System: A system for structured problem solving: identification, root-cause analysis (5 Whys, Ishikawa), three levels of action (immediate, corrective, preventive) and effectiveness verification on production data. It closes the PDCA cycle.
# MES Manufacturing Execution System: A system for managing and tracking the production process in real time - from the production plan through machine data collection to shift evaluation. It complements ERP downward toward the shop floor.
# ERP Enterprise Resource Planning: A corporate information system for managing finance, inventory, purchasing, human resources and sales (SAP, Oracle, Microsoft Dynamics, etc.). It typically sits "above" production - integration with MES is standard.
# CMMS Computerized Maintenance Management System: Software for asset records, preventive maintenance planning and work-order management. The traditional maintenance tool focused on "what's broken and who fixes it", without an operator layer or OEE.

# 5S Seiri, Seiton, Seiso, Seiketsu, Shitsuke: A five-phase method for workplace order: sort, set in order, shine, standardize, sustain. The foundation of visual management and lean manufacturing, a prerequisite for reliable TPM activity.
# PDCA Plan, Do, Check, Act: Deming's continuous improvement cycle: plan, do, check, act. The core of every action plan - without the Check and Act phases, improvement doesn't hold.
# Kaizen: A Japanese philosophy of continuous, small improvement with everyone's participation. The opposite of one-off large projects - kaizen relies on regularity and culture.
# Poka-Yoke: A design measure against errors - a "mistake-proof" solution that physically or logically prevents an operator error (e.g. a connector that fits only one way).
# Ishikawa diagram Fishbone: A visual tool for analyzing the causes of a problem, typically categorized by 6M: Man, Machine, Method, Material, Measurement, Milieu (environment). A complement to 5 Whys.
# 5 Whys Five Whys: A root-cause method: you ask "why" five times and gradually move from the symptom to the heart of the problem. Simple but surprisingly effective.

# OEE Overall Equipment Effectiveness: The key metric of overall equipment effectiveness, calculated as the product of Availability, Performance and Quality. A value above 85% is considered world-class in process manufacturing.
# MTBF Mean Time Between Failures: Mean time between failures - a metric of equipment reliability. It rises when preventive maintenance works and the root causes of failures are removed.
# MTTR Mean Time To Repair: Mean time to repair, from report to restoring operation. It falls with good maintenance organization, spare-parts availability and trained staff.
