Globális Gyártási Rendszer General Motors-Global Manufacturing System
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.
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
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) • Benefits • To External customers (people buying our vehicle). • Protect Customers from sub-standard vehicle quality. • Assure customer satisfaction • To Internal customer (downstream operation). • Prevent major repair and rework by detecting a non-conformity early in the process. • Prevent the flow of defects from department to department and station to station • To Internal customer (from supplier). • Protect Team Members from non-compliant parts from suppliers through advanced quality planning and prompt containment during spills.
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification)
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) • Process Equipment Capability Reviews (Prevention) • Periodic checks (typically monthly), are conducted to identify trends orshifts in capability over periods of time. • 1. Identify processequipment withhighrisk/impact • 2. Conduct initial capabilityconfirmation • 3. Conduct regularscheduled reviews toconfirm capability • 4.Implementcorrectiveaction asrequired
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) • Detection • Purpose of Detection: • To make non-standard conditions in the manufacturingprocessvisible - identify when defects or non-standardshave occurred. • This supports the “Do Not Accept”element of the quality motto: • inspection process that confirms quality assoon as possible following manufacture • measures the output of the manufacturingprocess • alerts organization to out of standardconditions • supports containment and provides inputinto continuousimprovement
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:
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.
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 on- and off-line) • Repair Confirmation must be conducted independently (e.g. by Quality). • Standardized work (non-cyclic) should be used for the confirmation • process – quality standards must be available. • Appropriate training and knowledge of standards must be developed to • conduct or confirm repairs. • Repair confirmation should be as close to the repair process as possible. • Repair confirmation can be conducted by man or machine.
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) Team has the ability to stop the line and complete standardized work in station. • Using Andon To Stop The Process: Work Station If the Team Member has a quality issue within their standardized work they activate the Andon system to: • initiate a call for help through station light, Andon board, and melody • empower the Team Member to stop line & organization responds toprovide support • stop at FPS (Fixed Position Stop) to contain and complete the repair • where Andon is not available the principles still apply
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: • ‘Go and See’ the problem • Apply containment to prevent furtherflow of defects • Initiate problem solving
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) • Purpose of Containment: • •The achievement of customer expectations relies on a method to containdefects within the manufacturing process, and implementcorrections toprotect the next/downstream customer. • •This supports the “Do Not Ship” element of thequality motto: • Containment • vehicle delivery to the customer • Powertrain and MFD plants to vehicleassembly • external supplier to themanufacturing plant • internal departments (e.g. between body,paint and GA) • between work stations within a department
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) • Containment Process Overview
Folyamatközi ellenőrzés és folyamat igazolás(In-Process Control and Verification) • Summary • Standardized work is performed in every process and includesthe required quality checks. • Process control activities are implemented on equipment tocontrol variation on a daily basis and maintain capability overa period of time. • Detection confirms the manufacturing process and ensuresboth internal (Production Team Members) and ExternalCustomers (people who buy our products) are receivingproducts that meet or exceed the quality standards. • A process is in place to contain defects within themanufacturing process and implement permanent correctiveactions that are verified as being effective.
Kockázatelemzési és hiba-megelőzési módszer, PFMEA (Process Failure and Effect Analysis) Purpose of this procedure: Investigation, documentation andif necessary reduction of the riskpotential (Risk Priority Number-RPN) for all productionprocesses • RISKPRIORITYNUMBER • S x O x D = RPN • S = Severity • O = Occurrence • D = Detection • RPN = Risk Priority Number* * 1 = Lowest 1000 = Highest
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: What do we do today to prevent the defect fromoccurring and getting to our customer ? • Recommended actions: If current controls are not 100% effective, whatactions should be taken ?
