Workshop Discussion • What methods can we use to protect the customer?
Workshop Discussion 100% Inspection – Does it work?
Will 100% inspection protect the customer? Scenario Oakland’s Marketing Department are very proud of the publications they produce. The customers of Oakland expect the highest quality publications. Therefore, the manager of the publications department has decided to employ you as an inspector at the end of the printing process to ensure that the text produced is accurate. You have 30 seconds to inspect the following set of text and count how many times the letter ‘F’ appears, (upper & lower case) including the title.

Process ImprovementMethodology Objective • Waste Elimination / Defect Reduction • Efficiency / Yield Improvement • Improved Customer Satisfaction • Higher Shareholder Value
What now? What focus? • Review • Project revision • Standardisation • Share learnings • Further improvement • Project goals/measures • Set up team • Map process • Measure process • Identify key problems • Find root causes • Identify solution • Plan for implementation Act Plan • Measurement • Assessment • Analysis Check • Prepare for implementation • Training • Communication • Implement improvement • Change management • Project management Do What happened? What action? Plan, Do, Check, Act
0. Emergency Response Action 1. Identify the team • Build cross-functional team • Protect the customer • Where, when, etc. • Is/Is not analysis • Process map • Measure and set objective 2. Define the problem • Short-term solution • Rescue affected customers 3. Contain the symptom • Use FMEA, Five Whys • Identify and check root cause 4. Identify root causes • Focus on fixing root causes • Set targets and owners for implementation 5. Choose corrective action • Implement to plan • Collect data to prove success 6. Implement corrective action • Documentation • Revise targets, FMEAs, etc. 7. Make change permanent • Recognise individuals and the team • Celebrate success 8. Recognise the team Global 8D
Define Measure Analyse Improve Control DMAIC • Identify champion and owner • Initial assessment of situation • Define scope and goals of project • Map process • Validate measurement system • Calculate process capability • Analyse for sources of variation • Identify potential root causes • Verify actual root cause • Develop solution • Create new process map • Cost / benefit analysis • Standardise • Sustain the gain • Develop control strategy

DRIVERA holistic approach • DRIVER training also includes ‘project management’ & ‘change management’
Lean Principles • Lean principles are based on the Toyota Production System (TPS) • TPS was developed after benchmarking the Ford Motor Company River Rouge plant in Detroit in the 1950’s. • The key characteristics of TPS / Lean are: • Only producing what is required, when it is required • Close links throughout the supply chain – just in time • Producing right first time • A lean mindset & company culture • The elimination of non-value added activity (waste)
Remove Waste, don’t Improve the Value-Add Total Throughput Time Value-add time Non-Value Add + Other time = + Usual Focus Work longer-harder-faster, add people, complexity or equipment Lean Eliminate Waste to Improve the Value Stream World Class Companies: ‘NVA’ = 80% TTT Typical ‘NVA’ = 99% TTT 26
Over-production Defects (Scrap/Rework) Inventory Motion Over-processing Waiting Transportation The 7 wastes 1 7 2 WASTE 6 3 5 4
A Lean Example LEAN Concepts • Standardised Work • Waste Elimination • Parallel Processing • Cell Layout • Batch Reduction • Quick Changeover • Line Balancing • Other Concepts • Visual Management • 5 S • Error Proofing
Workshop Discussion • Are Lean principles only applicable to manufacturing processes?
What is Six Sigma? • Six Sigma is focused on improving the quality of our products and services • How do we define the term ‘quality’? • The generic definition of quality is ‘meeting or exceeding the customer requirements’ • The customer of a process can be internal or external • Therefore, Six Sigma improves quality, thus, improving customer satisfaction
LSL USL Defects Defects Acceptable Customer Requirement Process Performance Six SigmaSatisfying the Customer Sigma is a capability metric that compares process performance against customer requirements
Is 99% Quality Good Enough? 3.8 Sigma 99% Good 6 Sigma 99.99966% Good 1 short or long landing every 5 years 2 short or long landings at an airport per day (200 daily flights) • Unsafe drinking water for almost 15 minutes each day Unsafe drinking water one minute every seven months 1.7 incorrect operations per week • 5,000 incorrect surgical operations per week (500,000 operations per week) 10,700 defects per million opportunities 3.4 defects per million opportunities
Quantifying Process Capability } Sigma is a universal measure of process performance

Variable Process Capability Analysis Capability is an assessment of: process spread as a ratio of the process tolerance. – Cp / Pp LSL USL Tolerance Process spread Cpk / Ppk isthe location of the process mean with respect to both process specification limits. LSL USL Mean
