Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) The GMS element “In-Process Control & Verification” incorporates the intent and purpose of the BIQ motto: Quality expectations are achieved in each process to ensure defects are not passed on to downstream process. 5
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Customer satisfaction achievement Customer satisfaction is achieved through three sub-elements: • Prevention: avoid defects or non-standards occurring • Detection: identify when defects or non-standards have occurred • Containment: assure defects or non-standards are not passed on 6
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Benefits Ø To External customers (people buying our vehicle). • Protect Customers from sub-standard vehicle quality. • Assure customer satisfaction Ø To Internal customer (downstream operation). • Prevent major repair and rework by detecting a non-conformity early in the process. • station Prevent the flow of defects from department to department and station to Ø To Internal customer (from supplier). • Protect Team Members from non-compliant parts from suppliers through advanced quality planning and prompt containment during spills. 7

Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Process Equipment Capability Reviews (Prevention) Periodic checks (typically monthly), are conducted to identify trends or shifts in capability over periods of time. 1. Identify process equipment with high risk/impact 2. Conduct initial capability confirmation 3. Conduct regular scheduled reviews to confirm capability 4. Implement corrective action as required 9
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Detection Purpose of Detection: Ø To make non-standard conditions in the manufacturing process visible - identify when defects or non-standards have occurred. ØThis supports the “Do Not Accept” element of the quality motto: § inspection process that confirms quality as soon as possible following manufacture § measures the output of the manufacturing process § alerts organization to out of standard conditions § supports containment and provides input into continuous improvement 10
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Quality Check System Update Internal/external ‘Customers’ are monitored for feedback: Where there is an indication of defect flow-out through the Verification process, a systematic analysis will be conducted; typically for: 11
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Inspection Frequencies of Critical Operations The quality check system must be established in consideration of the ‘Supplier-Customer’ relationship. Inspection frequencies must be established by each ‘supplier’ that prevent shipping defects to downstream ‘customers’. This is a requirement for safety & compliance items, key characteristics and for issues that will significantly impact the next process or customer. 12
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Independent Repair Confirmation During a repair, the risk for a discrepancy to occur is increased - many aspects of the repair operation are non-standard: Any documented repair must be verified by Repair Confirmation (both onand off-line) Ø Repair Confirmation must be conducted independently (e. g. by Quality). Ø Standardized work (non-cyclic) should be used for the confirmation Ø process – quality standards must be available. Ø Appropriate training and knowledge of standards must be developed to Ø conduct or confirm repairs. Ø Repair confirmation should be as close to the repair process as possible. Ø Repair confirmation can be conducted by man or machine. 13
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Using Andon To Stop The Process: Work Station Team has the ability to stop the line and complete standardized work in station. If the Team Member has a quality issue within their standardized work they activate the Andon system to: Ø initiate a call for help through station light, Andon board, and melody Ø empower the Team Member to stop line & organization responds to provide support Ø stop at FPS (Fixed Position Stop) to contain and complete the repair Ø where Andon is not available the principles still apply 14
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Alarm & Escalation Processes When a defect is detected, feedback to the appropriate team or individual will be given by using a communication system. The alarm is raised by using audio/visual signals (e. g. Andon). The alarm process directs the support functions to: Ø ‘Go and See’ the problem Ø Apply containment to prevent further flow of defects Ø Initiate problem solving 15
Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Containment Purpose of Containment: • The achievement of customer expectations relies on a method to contain defects within the manufacturing process, and implement corrections to protect the next/downstream customer. • This supports the “Do Not Ship” element of the quality motto: Ø vehicle delivery to the customer Ø Powertrain and MFD plants to vehicle assembly Ø external supplier to the manufacturing plant Ø internal departments (e. g. between body, paint and GA) Ø between work stations within a department 16

Folyamatközi ellenőrzés és folyamat igazolás (In-Process Control and Verification) Summary Ø Standardized work is performed in every process and includes the required quality checks. Ø Process control activities are implemented on equipment to control variation on a daily basis and maintain capability over a period of time. Ø Detection confirms the manufacturing process and ensures both internal (Production Team Members) and External Customers (people who buy our products) are receiving products that meet or exceed the quality standards. Ø A process is in place to contain defects within the manufacturing process and implement permanent corrective actions that are verified as being effective. 18
Kockázatelemzési és hiba-megelőzési módszer, PFMEA (Process Failure and Effect Analysis) Purpose of this procedure: Investigation, documentation and if necessary reduction of the risk potential (Risk Priority Number-RPN) for all production processes RISK PRIORITY NUMBER S x O x D = RPN • S = Severity • O = Occurrence • D = Detection • RPN = Risk Priority Number* * 1 = Lowest 1000 = Highest 19
Kockázatelemzési és hiba-megelőzési módszer, PFMEA (Process Failure and Effect Analysis) Potential failure mode: What things have gone wrong ? What things could go wrong ? Effects of failure: What does a failure mean to the next operation, the assy plant, the final customer? Potential Cause of failure: Root cause what has gone wrong in the past Brainstorm what could cause failures? Current controls: Recommended actions: What do we do today to prevent the defect from occurring and getting to our customer ? If current controls are not 100% effective, what actions should be taken ? 20
