Manufacturing glossary

Digital work instructions

Digital work instructions (DWI) are step-by-step procedures delivered to shop-floor operators on a tablet or screen, replacing paper instructions with rich media, live data, and automated sign-off.

Skill matrix

A skill matrix is a grid that maps each operator to every skill they can perform, with a competency level for each pair — used on the shop floor to plan shifts, gate work-instruction access, and surface training gaps.

Connected worker

A connected worker is a shop-floor operator equipped with a digital device (tablet, wearable, phone) that delivers work instructions, captures data, and ties their actions to the broader manufacturing and quality systems in real time.

Manufacturing Execution System

A Manufacturing Execution System (MES) orchestrates and records what happens on the shop floor: which work order is on which machine, who performed which step, what materials were consumed, and whether the resulting product passed quality.

Traceability

Traceability in manufacturing is the ability to reconstruct, forward and backward, the full genealogy of a product: which raw materials, components, operators, machines, and process parameters went into a given serial or lot.

Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) is the single-number measure of how well a manufacturing operation runs its equipment, calculated as Availability × Performance × Quality and expressed as a percentage.

5S

5S is a lean workplace-organization method built on five Japanese words (Sort, Set in order, Shine, Standardize, Sustain) used to keep shop-floor areas safe, clean, and efficient through regular audits.

Continuous improvement

Continuous improvement is the ongoing, structured practice of making small, measurable changes to processes, products, and services so performance improves over time — often implemented with tools like kaizen events, PDCA, and an improvement-ticket backlog.

Heijunka

Heijunka is a Toyota Production System technique that smooths production volume and product mix over time, replacing long runs of a single variant with short, interleaved runs that match demand — reducing inventory, lead time, and overburden.

ALCOA principle

ALCOA is a regulatory data-integrity framework requiring records in GxP-regulated manufacturing to be Attributable, Legible, Contemporaneous, Original, and Accurate — with the "+" extension adding Complete, Consistent, Enduring, and Available.

Electronic batch record

An electronic batch record (eBR) is the digital, auditable file that captures every step, parameter, deviation, and sign-off for a single manufactured batch — replacing the paper batch record used in pharma, food, chemicals, and other regulated industries.

IATF 16949

IATF 16949 is the global quality-management standard for automotive production and relevant service-part manufacturing, built on top of ISO 9001 with additional automotive-specific requirements around defect prevention, variation control, and supply-chain management.

8D report

An 8D report is a structured, eight-step problem-solving method (D1–D8) used in manufacturing quality to isolate, contain, resolve, and prevent recurrence of a non-conformance, typically in response to a customer complaint.

CAPA

CAPA (Corrective and Preventive Action) is a regulated quality process for investigating non-conformances, correcting them, and putting preventive measures in place so they do not recur — mandatory under ISO 9001, IATF 16949, ISO 13485, FDA 21 CFR Part 820, and GMP.

Non-conformance

A non-conformance is any product, process, or document that does not meet its specification or requirement — formally logged, classified, dispositioned, and (when required) escalated into a CAPA.
