Sigma is a Greek letter, it is a term in statistics to describe the variation of process and standard value , in statistics it is used to represent the dispersion of data, and to describe the probability of defects .

6-Sigma: is a very demanding process to help enterprises to realise near-perfect quality objectives , a decision method based on data, the objective is to improve quality, reduce cost, maximize value, customer satisfaction / market competitiveness and a commitment to the process of continual improvements.

It is a defined production or service process standard,  it use data for description, 6-Sigma can be represented by PPM=3.4, that is, for every 1,000,000 units(or service) the defect is less than 3.4 units.

6-Sigma Benefits to organization :

  1. Enable organisations rapidly increase ability to win customers and market at the same time reduce cost
  2. Enhance management and product quality
  3. Prevent potential defects, reduce quality cost, increase efficiency
  4. Improve overall operation processes, employee attitude improvement and fitness in competition.

6-Sigma core process:

This innovative method is through Define, Measure, Analyse, Improve, Control (DMAIC) core processes.  DMAIC is used in three essential improvement processes:

  • 6-Sigma product / service realization process;
  • 6-Sigma business process improvement;
  • 6-Sigma design SSDP.

Establish 6-Sigma Management Process:

1. Top-down driven process, lead by the top management. Top management raise improvement/innovation objective (this objective is closely related to the strategy and vision of organizational development) , resources and time frame.

2. Process Control:

Define D: Define core problem, define improvement project objectives and identify critical characteristics CTQ.

Measure M: Measure present level, establish improved baseline.

Analyse A: Analyse present level and target level gap and root cause of the problems

Improve I: Use economic and effective methods to seek breakthrough and improvement.

Control C: Setup maintenance measures, standardise, replicate in similar products and processes, also apply to the development of new products/services.

3. Applicable Technology:

  • Measuring Technology: DPMO measuring methods, process capability analysis (including short/long term analysis)
  • Fundamental Technology: New, old seven tools
  • Advanced Technology:
    • SPC, variation of improvement and monitoring process
    • DOE to improve design, achieve excellence in process capability
    • FMEA, assistance in defining improvement projects, setup improvement objectives
    • QFD, convert customer requirements to internal work orders
    • Fault prevention, to prevent defects from root cause
  • Soft Technology:
    • leadership
    • improve team work
    • employee ability and empowerment
    • communication and feedback

4. Objectives:

  • Through training people with defined responsibility to ensure market share
  • Increase customer return rate;  reduce cost; reduce cycle time
  • Reduce defect rate; speed up product / service development; culture change

5. Managing Team

DMAIC applicable to operation level, strategic units (business units) levels and product / service projects.

1) Samura: Senior manager with 6-Sigma implementation responsibility. Planning 6-Sigma implmentation and overall supports. Responsible for identify and select 6-Sigma projects. follow up or monitor 6-Sigma progress.

2) Big Black Belt: 6-Sigma technical application overall responsibility. Assist Samura in project selection, preare implementation plan and time frame, provide 6-Sigma  to black belt; support advanced technical tools, responsible for mobilise, co-ordinate , and communication.

3) Black Belt: Come from different Departments, attended 6-Sigma renovation process and tools training, responsible for instruction or leading a project. provide training and instruction to green belts.

4) Green Belt: Attended training, participate 6-Sigma project from his own position.

Proportion: For every 1000 emplyees; Big Black Belt: One一名; Black Belt: 10; Green Belt: 50-70.

6. Continous improvements

  1. Performance Monitoring System establishment;
  2. Setup Self Improvement Mechanism.

FormalWin’s Role in 6-Sigma:

  1. Consultant team with industrial experiences to conduct indepth gap analysis, redesign process flow, identify core problems, find out what are the most appropriate tools and processes required.
  2. Train employees on management concepts, not on operation techniques.
  3. Implement business process flow for the organisation, identify deviation from the objectives.
  4. After delivery, a periodic evaluation is applied, adjust slipages from time to time.
  5. Emphasis on training, different training for different levels, appropriate courses for employees to understand6-Sigma, cultivate continuous improvement culture.
  6. Focus on team spirit, co-operative spirit, enable 6-Sigma system implementation, enhance effectiveness.
