Introduction to six sigma
Six sigma is a highly structured strategy for acquiring, assessing, and applying customer, competitor, and enterprise intelligence for the purposes of product, system or enterprise innovation and design.
Six Sigma is a proven systematic approach to improve measurable results for any organization
Historical back groundSix Sigma is a business
management strategy originally developed by Motorola in 1986 in USA. Founder of six sigma was bill smith.
Six Sigma Affects Six Areas Fundamental to Improving a Company’s Value
1. Process Improvement2. Product & Service Improvement3. Investor Relations4. Design Methodology5. Supplier Improvement6. Training & Recruitment
Methods Six Sigma projects follow two project
methodologies DMAIC DMADV
Methods DMAIC is used for projects aimed at
improving an existing business process.The DMAIC project methodology has
five phases:Define the problem, the voice of the
customer, and the project goals, specifically.
Measure key aspects of the current process and collect relevant data.
Methods Analyze the data to investigate and
verify cause-and-effect relationships. Determine what the relationships are, and attempt to ensure that all factors have been considered. Seek out root cause of the defect under investigation.
Methods Improve or optimize the current
process based upon data analysis using techniques such as design of experiments or mistake proofing, and standard work to create a new, future state process. Set up pilot runs to establish process capability.
Methods Control the future state process to
ensure that any deviations from target are corrected before they result in defects. Implement control systems such as statistical process control, production boards, and visual workplaces, and continuously monitor the process.
Methods DMADV is used for projects aimed at
creating new product or process designs.
The DMADV project methodology have features five phases.
Define design goals that are consistent with customer demands and the enterprise strategy.
Methods Measure and identify CTQs
(characteristics that are Critical To Quality), product capabilities, production process capability, and risks.
Methods
Analyze to develop and design alternatives, create a high-level design and evaluate design capability to select the best design.
Methods Design details, optimize the design,
and plan for design verification. This phase may require simulations.
Methods Verify the design, set up pilot runs,
implement the production process and hand it over to the process owner.
How do we design six sigma
How do we design six sigmaDefine : customer requirements and goals
for the process product and servicesMeasure : and match performance to
customer requirements. Analyze : and asses the design for the
process product and services.Design : and implement the array of new
process required for the new process product and services.
Verify : results and maintain performance.
Stages of six sigmaThere are five stages of six sigma1. Defining2. Measuring3. Analyzing4. Improving5. Controlling
Role of six sigmaExecutives ChampionMaster black beltBlack beltGreen beltProcess ownerSix sigma team
Roles : Executives
EXECUTIVES: organization should have a Six
Sigma council or equivalent body to oversight and represent Six Sigma. The executive will be concerned with corporate level, goals and targets.
Roles : Champion
CHAMPION: Can be used to describe anybody
who ‘champions’ Six Sigma, but usually refers to a senior executive who takes responsibility for Six Sigma projects and oversees, supports, finds resources, and monitors progress.
Roles : Master Black Belt
MASTER BLACK BELT: An expert in six sigma
management responsible for six sigma monitoring and training for the technical and professional standards of six sigma. In companies there is only one master black belt for every thousands employees.
Roles : Black Belt
BLACK BELT: Black belts are experts in six
sigma who manages six sigma projects. In companies there is only one black belt for every hundreds employees.
Black Belt Act as Breakthrough Strategy
experts and be Breakthrough Strategy enthusiasts.
Stimulate Champion thinking. Identify the barriers. Lead and direct teams in project
execution. Report progress to appropriate
leadership levels.
Black Belt Solicit help from Champions when
needed. Influence without direct authority. Determine the most effective
tools to apply. Prepare a detailed project
assessment during the Measurement phase.
Black Belt Get input from knowledgeable
operators, first-line supervisors, and team leaders.
Teach and coach Breakthrough Strategy methods and tools.
Manage project risk. Ensure that the results are
sustained.
Roles : Green BeltsGREEN BELTS: Green belts are similar to black
belts but are less qualified particularly in statistical methods. They can lead a smaller projects under the supervisions on black belts.
Green Belt Function as Green Belts on a part-time
basis, while performing their regular duties.
Participate on Black Belt project teams in the context of their existing responsibilities.
Learn the Six Sigma methodology as it applies to a particular project.
Continue to learn and practice the Six Sigma methods and tools after project completion.
Roles : process owner
PROCESS OWNER: The manager or the supervisor of
the section most concerned with the projects. They will b responsible for the process after six sigma process is completed.
Roles :six sigma team
SIX SIGMA TEAM: The people who work for the six
sigma project under the supervision of black belt. Six sigma team is best to kept small six people or less.
Levels of Six Sigma“Sigma” means standard deviation and
therefore Six Sigma means six standard deviations.
