Quality & Human Error
Management Training
A hands-on training program designed to prevent quality defects systematically, reduce human error and build a sustainable quality management system into your processes.
Why Quality and Human Error Management?
Quality defects and human-related disruptions are among the costliest sources of loss in production. Instead of reactive corrections, systematic prevention tools stop errors at source, manage operator behaviour and make the quality culture permanent.
Program Content — Tools & Methods
From root cause analysis of quality defects to human error management, and from QA Matrix design to TWTTP implementation, the training covers every component of a sustainable quality system.
Quality Defects & the Root Cause Approach
Covers how quality defects are classified, how they are addressed through root cause logic, and how preventive actions are designed.
QA Matrix
Designing and deploying the QA Matrix, which defines quality control points, methods and responsibilities process by process.
4M Analysis
Systematically assessing the impact of Machine, Material, Method and Man factors on quality, and prioritising improvements.
Human Errors & Error Types
Why human errors occur, the error types (slip, lapse, mistake) and determining the right prevention strategy for each type.
TWTTP — The Way to Teach People
The TWTTP approach, which distinguishes whether an operator error stems from a missing standard or from intent, and sets the intervention method accordingly.
The Quality–Process–Operator Relationship
Covers how quality output is linked to process design and operator competence, and how to build systemic quality management.
Daily Program Flow
The morning block covers quality and human error theory tool by tool; in the afternoon a QA Matrix is built around a sample problem, a root cause analysis is run with 4M and a real human error scenario is resolved using the TWTTP method.
Application & Workshop (13:30 – 16:00)
- Building a QA Matrix around a sample problem
- Root cause analysis exercise with 4M
- Human error scenario analysis
- TWTTP worked example
Quality Defects & the QA Matrix
Covers quality defect classification, the root cause approach, and the structure and design logic of the QA Matrix.
Human Error, TWTTP & 4M
Human error types, the TWTTP approach, 4M analysis and the quality–process–operator relationship are covered with examples.
QA Matrix & 4M Workshop
A group-based QA Matrix is built around a sample problem and a 4M root cause analysis is applied.
Human Error Scenario & TWTTP
A real human error scenario is analysed with the TWTTP method; an intervention strategy and action plan are produced.
By the End of the Training, Participants…
Participants who complete the training address quality defects with a systematic preventive approach rather than a reactive one, and can apply the QA Matrix and 4M on the shop floor independently.

Who Is This Training For?
Quality & Human Error Management training suits every operations and quality team that wants to prevent quality defects systematically and build a sustainable quality culture.
Operations Managers
Managers who want to manage quality losses with systematic prevention tools.
Manufacturing Engineers
Engineers who want to embed the QA Matrix and 4M analysis into process design.
Quality Engineers & Teams
Professionals who want to analyse quality defects at root cause level and build a preventive system.
Continuous Improvement Teams
Teams that integrate quality and human error management with CI programs.
Consultant & Instructor
With over 25 years of experience in automotive and manufacturing, Ertuğrul Turgay designs programs that take quality management and human error prevention systems to the shop floor through the WCM methodology. He treats the QA Matrix, TWTTP and 4M analysis not as theoretical tools but as practical systems that change shop-floor behaviour directly.
