A system that uses data analysis to improve an organisation’s operating performance.
A system that targets the reduction of variation to improve the outcomes of a process.
What is Six Sigma?
Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes . It uses a set of quality management methods, including statistical methods , and creates a special infrastructure of people within the organization ("Black Belts", "Green Belts", etc.)
What do you want to achieve for the customer? Commitment to Customer (Set Specific Goals)
Example – Define Customer – General Manager (Internal) VOC – Reduce the wastage of raw materials (plastic parts) to 3% of total. (Recycle?) Our Commitment to the Customer To develop and implement operational improvements to achieve a wastage rate of plastic parts to 3% of the total consumption per month within a three month period. (Set Targets/ Time Management)
D M AIC - Measure
“ If you can’t measure it you can’t manage it” (Understanding key issues)
What to measure? (Describe)
How to measure? (Provide training/Hand-on)
Example - Measure
At commencement of project it is known that the total wastage of plastic components is 11% per month
The quantities attributable to different sources is not yet known
Data collection is required (Coordinate amongst all Production wings/Section)
DM A IC - Analyse
What does my data mean? (Understand and compare)
How much mathematics do I really need? (Check the loop holes)
What tools can I use? (Set new targets)
DMA I C - Improve
Improve the target process by designing creative solutions to fix or prevent problems. (Be Proactive)
Create innovative solutions using technology and discipline (Share the ideas)
Develop and deploy implementation plan (Maintain and Retain)
DMAI C - Control
Control the improvements to keep the process on the new course. (Maintain them)
Prevent reverting t o the "old way" (Avoid old thumb roles)
Require the development, documentation and implementation of an ongoing monitoring plan
Institutionalize s e the improvements through the modification of systems and structures (specialised staffing, training, incentives)
R DMAIC R
R ecognise the need for improvement
R ealize the benefits!!
Not identifying the “customer”
Not understanding VOC
Too many projects
Statistics v results
Poor team selection
Lack of a mentor
Insufficient project monitoring and review
Organisation’s influencers not on board
Two Key Points
Six Sigma is a system that can be used effectively to grab the easy Targets as well as that which is harder to achieve .
