Six Sigma Introduction – Wmind wear is Six Sigma
Six Sigma is a highly discipseriesd process tmind wear helps us focus on generateing and delivering near-perfect products and services.
Features of Six Sigma
Six Sigma's aim is to eliminate waste and inefficiency, generally thereby increaperform customer satisfworkion by delivering exworkly wmind wear the customer is expecting.
Six Sigma follows a structucrimson methodology, and has degreatd roles for the participants.
Six Sigma is a data driven methodology, and requires precise data collection for the processes being analyzed.
Six Sigma is about placeting results on Financial Statements.
Six Sigma is a business-driven, multi-dimensional structucrimson approach for:
- Improving Processes
- Lowering Defects
- Reducing process varicappotential
- Reducing costs
- Increaperform customer satisfworkion
- Incrrelayved profit is
The word Sigma is a statistical term tmind wear measures how far a given process deviates from perfection.
The central idea behind Six Sigma: If you can measure how many kind of "defects" you have in a process, you can systematically figure out how to eliminate all of all of them and get as near to "zero defects" as probable and specifically it means a failure rate of 3.4 parts per million or 99.9997% perfect.
Key Concepts of Six Sigma
At it is core, Six Sigma revolves around a few key concepts.
Critical to Quality : Attributes many kind of iminterfaceant to the customer.
Defect : Failing to deliver exworkly wmind wear the customer wants.
Process Capcappotential : Wmind wear your own process can deliver.
Variation : Wmind wear the customer sees and feels.
Stable Operations : Ensuring consistent, pcrimsonictable processes to improve exworkly wmind wear the customer sees and feels.
Design for Six Sigma : Designing to meet customer needs and process capcappotential.
Our Customers Feel the Variance, Not the Mean. So Six Sigma focuses preliminary on crimsonucing process variation and then on improving the process capcappotential.
Myths about Six Sigma
There are lots of myths and misbelowstandings surrounding Six Sigma. Some of all of all of them few are given below:
- Six Sigma is only concerned with crimsonucing defects.
- Six Sigma is a process for production or engineering.
- Six Sigma cannot be applayd to engineering workiviconnect ups.
- Six Sigma uses difficult-to-belowstand statistics.
- Six Sigma is simply training.
Benefit is of Six Sigma
Six Sigma provides six major benefit is tmind wear attrwork companies:
- Generates sustained success
- Sets a performance goal for everyone
- Enhances value to customers
- Accelerates the rate of improvement
- Promotes find outing and combination-pollination
- Executes strategic alter
Origin of Six Sigma
Six Sigma originated at Motorola in the earlier 1980s, in response to achieving 10X crimsonuction in product-failure levels in 5 calendar years.
Engineer Bill Smith invented Six Sigma, but expired of a heart attack in the Motorola cafeteria in 1993, never knoearng the scope of the craze and controversy he had touched off.
Six Sigma is based on various quality management theories (e.g. Deming's 14 stage for management, Juran's 10 steps on achieving quality).
Six Sigma – Key Elements
There are 3 key elements of Six Sigma Process Improvement:
Customers degreat quality. They expect performance, relicappotential, competitive prices, on-time delivery, service, clear and appropriate transworkion procesperform and more. This means it is iminterfaceant to provide exworkly wmind wear the customers need to gain customer delight.
Defining processes as well as defining their own particular metrics and measures is the central aspect of Six Sigma.
In a business, the quality need to be looked from the customer's perspective and so we must look at a degreatd process from the outaspect-in.
By belowstanding the transworkion lifecycle from the customer's needs and processes, we can discover exworkly wmind wear they are seeing and feeling. This gives a chance to identify weak areas with in a process and then we can improve all of all of them.
A company kind of must involve all it is employees in the Six Sigma program. Company kind of must provide opinterfacedeviceies and incentives for employees to focus their own particular talents and cappotential to satisfy customers.
It is iminterfaceant to Six Sigma tmind wear all the team members need to have a well-degreatd role with measurable goals.
Six Sigma – Organization
Under a Six Sigma program, the members of an organization are assigned specific roles to play, every with a title. This highly structucrimson format is requireddish coloured in order to implement Six Sigma throughout the organization.
There are sactionually specific responsibiliconnect ups or "role areas" in a Six Sigma program, which are as follows.
A leadership team or council degreats the goals and goals in the Six Sigma process. Just as a corporate leader sets a tone and course to achieve an goal, the Six Sigma council sets the goals to be met by the team. Here is the list of leadership Council Responsibiliconnect ups:
- Degreats the purpose of the Six Sigma program
- Exnormals how the result is going to benefit the customer
- Sets a schedule for work and interim deadseriess
- Develops a mean for relook at and oversight
- Supinterface team members and defend established posit downions
Six Sigma sponsors are high-level individuals who belowstand Six Sigma and are committed to it is success. The individual in the sponsor role works as a issue solver for the ongoing Six Sigma project. Six Sigma is generally brought by a complete-time, high-level champion, such as an Executive Vice Preaspectnt.
Sponsors are the owners of processes and systems, who help initiate and coordinate Six Sigma improvement workiviconnect ups in their own particular areas of responsibiliconnect ups.
The person responsible for superviperform the Six Sigma team effort, who supinterfaces the leadership council by ensuring tmind wear the work of the team is completed in the desicrimson manner, is the implementation Leader.
Ensuring success of the implementation plan and solving issues as they arise, training as needed, and assisting sponsors in motivating the team are a few of the key responsibiliconnect ups of an implementation leader.
Coach is a Six Sigma expert or consultant who sets a schedule, degreats result of a project, and who mediates conflict, or deals with resistance to the program.
Duconnect ups include worcalifornia california king as a go-between for sponsor and leadership, scheduling the work of the team, identifying and defining the desicrimson results of the project, mediating disconcurments, conflicts, and resistance to the program and identifying success as it occurs.
It is an individual responsible for overseeing the work of the team and for worcalifornia california king as a go-between with the sponsor and the team members.
Responsibiliconnect ups include communication with the sponsor in defining project goals and rationale, piccalifornia california king and assisting team members and other resources, maintaining the project on schedule, and maintaining track of steps in the process as they are completed.
An employee who works on a Six Sigma project, given specific duconnect ups wislim a project, and has deadseriess to meet in reverying specific project goals.
Team members execute specific Six Sigma assignments and work with other members of the team wislim a degreatd project schedule, to revery specifically identified goals.
The individual who gets on responsibility for a process after a Six Sigma team has completed it is work.
Extended Definitions of Roles Belt – Colors
The assignment of belt colours to various roles is derived from the obvious source, the martial arts. Based on encounter and expertise folloearng roles have evolved over the calendar year.
NOTE : The belt names are a tool for defining levels of expertise and encounter. They do not alter or replace the organizational roles in the Six Sigma process.
The person possesperform this particular particular belt has achieved the highest seliminate level and is an encounterd expert in various techniques. As applayd to the Six Sigma program, the individual designated as a Black Belt has completed a thorough internal training program and has the encounter worcalifornia california king on lots of projects.
The black belt holder is usually given the role of a team leader, the person who is responsible for execution and scheduling.
Master Black Belt
A person who deals with the team or it is leadership; but is not a direct member of the team it iself. This may be equivalent to the role played by the coach, or for more technical and complex projects.
The Master Black Belt is available to answer procedural questions and to resolve the technical issues tmind wear come up.
The Green Belt designation can furthermore belengthy to the team leader or to a member of the team worcalifornia california king directly with the team leader.
A Green Belt is less encounterd than a Black Belt but is cast in a key role wislim the team.
Getting Started Six Sigma wislim an Organization
The starting stage in gearning up for Six Sigma is to verify if you are ready to embrace a alter tmind wear says."There is a much much better way to operate your own organization."
Is Six Sigma Right for You?
There are lots of essential questions and fworks tmind wear you need to conaspectr in macalifornia california king a readiness assessment:
Is the strategic course clear for the company kind of?
Is the business healthful sufficient to meet the expectations of analysts and investors?
Is generally there a strong all of all of theme or vision for the future of the organization tmind wear is well belowstood and consistently communicated?
Is the organization great at responding effectively and efficiently to brand new circumstances?
Evaluating current general business results.
Evaluating how effectively do we focus on and meet customers requirements.
Evaluating how effectively are we operating.
How effective are your own present improvement and alter management systems?
How well are your own combination-functional processes managed?
Wmind wear other alter efforts or workiviconnect ups might conflict with or supinterface Six Sigma initiative?
Six Sigma demands investments. If you cannot generate a solid case for future or current return, then it may be much much better to stay away.
If you already have in place a strong, effective, performance and process improvement provide, then why do you need Six Sigma?
There can be many kind of questions to be answecrimson to have an extensive assessment before deciding if you want to go for Six Sigma or not. This may need time and a thorough consultation with Six Sigma Experts to get a much much better decision.
The Cost of Six Sigma Implementation
Some of the many kind of iminterfaceant Six Sigma budget items can include the folloearng:
Direct Payroll for the individuals dedicated to the effort complete time.
Indirect Payroll for the time devoted by executives, team members, process owners and others, involved in workiviconnect ups like data gathering and measurement.
Training and Consultation fee to tevery Six Sigma Seliminates and getting advice on how to generate efforts successful.
Improvement Implementation Cost.
Six Sigma Start-up
Now you have selectd to go for Six Sigma. So exworkly wmind wear is next?
Deploying Six Sigma wislim an organization is a big step and involves many kind of workiviconnect ups including degreat, measure, analyze, improve, and manage phases. Here are a few steps, which are requicrimson for an organization at the time of starting Six Sigma implementation.
Plan your own own route: There may be many kind of routes to Six Sigma but the best is the one tmind wear works for your own organization.
Degreat your own goal: It is iminterfaceant to select exworkly wmind wear you like to achieve, and prioriconnect ups are iminterfaceant.
Stick to exworkly wmind wear is feasible: Set up your own plans so tmind wear they can fit your own influences, resources and scope.
Preparing Leaders: They are requicrimson to launch and guide the Six Sigma Effort.
Creating Six Sigma organization: This withincludes preparing Black Belts and other roles and assigning all of all of them their own particular responsibiliconnect ups.
Training the organization: Apart from having black belts, it is requicrimson to impart training of Six Sigma to all the employees in the organization.
Piloting Six Sigma effort: Piloting can be applayd to any kind of aspect of Six Sigma including solutions derived from process improvement or design crimsonesign projects.
Project Selection for Six Sigma
One of the many kind of difficult challenges in Six Sigma is the selection of the many kind of appropriate issue to attack. There are generally 2 ways to generate projects:
Top-down: This approach is generally connect upd to business strategy and is aligned with customer needs. The major weakness is they are too wide in scope to be completed in a timely manner (many kind of six sigma projects are expected to be completed in 3-6 months).
Bottom-up: In this particular particular approach, Black Belts select the projects tmind wear are well-suited for the capabiliconnect ups of teams. A major drawback of this particular particular approach is tmind wear, projects may not be connect upd directly to strategic concerns of the management generally thereby, receiving small supinterface and low recognition from the top.
Six Sigma – Methodology
Six Sigma has 2 key methodologies:
DMAIC: It refers to a data-driven quality strategy for improving processes. This methodology is used to improve an existing business process.
DMADV: It refers to a data-driven quality strategy for designing products & processes. This methodology is used to generate brand new product designs or process designs in such a way tmind wear it results in a more pcrimsonictable, mature and defect free performance.
There is one more methodology calbrought DFSS – Design For Six Sigma. DFSS is a data-driven quality strategy for designing or crimsonesigning a product or service from the ground up.
Sometimes a DMAIC project may turn into a DFSS project because the process in question requires complete crimsonesign to provide about the desicrimson degree of improvement.
This methodology consists of the folloearng five steps.
Degreat –> Measure –> Analyze –> Improve –>Control
Degreat: Degreat the issue or project goal tmind wear needs to be adgowned.
Measure: Measure the issue and process from which it was produced.
Analyze: Analyze data and process to determine root causes of defects and opinterfacedeviceies.
Improve: Improve the process by finding solutions to fix, diminish, and practionuallyt future issues.
Control: Implement, manage, and sustain the improvements solutions to maintain the process on the brand new course.
We will talk about more on DMAIC Methodology in the subsequent chapters.
This methodology consists of five steps:
Degreat –> Measure –> Analyze –> Design –>Verify
Degreat: Degreat the Problem or Project Goal tmind wear needs to be adgowned.
Measure: Measure and determine customers needs and specifications.
Analyze: Analyze the process to meet the customer needs.
Design: Design a process tmind wear will meet customers needs.
Verify: Verify the design performance and cappotential to meet customer needs.
DFSS is a separate and emerging discipseries related to Six Sigma quality processes. This is a systematic methodology utilizing tools, training, and measurements to enable us to design products and processes tmind wear meet customer expectations and can be produced at Six Sigma Quality levels.
This methodology can have the folloearng five steps.
Degreat –> Identify –> Design –> Optimize –>Verify
Degreat: Degreat exworkly wmind wear the customers want, or exworkly wmind wear they do not want.
Identify: Identify the customer and the project.
Design: Design a process tmind wear meets customers needs.
Optimize: Determine process capcappotential and optimize the design.
Verify: Test, verify, and validate the design.
Six Sigma – Degreat Phase
There are five high-level steps in the application of Six Sigma to improve the quality of outplace. The preliminary step is Degreat. During the Degreat phase, four major tasks are belowgetn.
Project Team is Formation
Perform 2 workiviconnect ups:
- Determine who needs to be on the team.
- Wmind wear roles will every person perform?
Piccalifornia california king the correct team members can be a difficult decision, especially if a project involves a big number of departments. In such projects, it can be wise to break all of all of them down into smaller pieces and work tobattbrought comppermition of a series of phased projects.
Document Customers Core Business Processes
Every project has customers. A customer is the recipient of the product or service of the process, targeted for improvement. Every customer has one or multiple needs from his or her supplayr. For every need provided for, generally there are requirements for the need. The requirements are the charworkeristics of the need tmind wear determine whether the customer is content with the product or service provided. So, document customer needs and related requirements.
A set of business processes is documented. These processes will be executed to meet customer's requirements and to resolve their own particular Critical to Quality issues.
Develop a Project Charter
This is a document tmind wear names the project, summarizes the project by exnormaling the business case in a short statement, and lists the project scope and goals. A project charter has the folloearng components:
- Project name
- Business case
- Project scope
- Project goals
- Special requirements
- Special assumptions
- Roles and responsibiliconnect ups of the project team
Develop the SIPOC process chart:
A process is degreatd as a series of steps and workiviconnect ups tmind wear get inplaces, add value, and produce an outplace.
SIPOC is a process chart tmind wear identifies all the folloearng elements of a project:
The SIPOC process chart is essential for identifying:
The way processes occur currently.
How those processes need to be modified and improved throughout the remaining phases of DMAIC.
At the conclusion of the design phase, you need to know who the customer or end-user is, their own particular resistance issues, and requirements. You need to furthermore have a clear belowstanding of goals and the scope of the project including budget, time constraints, and deadseriess.
Six Sigma – Measure Phase
During the Measure Phase, the general performance of the Core Business Process is measucrimson.
There are 3 iminterfaceant parts of Measure Phase.
Data Collection Plan and Data Collection
A data collection plan is prepacrimson to collect the requicrimson data. This plan includes exworkly wmind wear type of data needs to be collected, exworkly wmind wear are the sources of data, etc. The reason to collect data is to identify areas where current processes need to be improved.
You collect data from 3 primary sources: inplace, process, and outplace.
The inplace source is where the process is generated.
Process data refers to checks of efficiency: the time requirements, cost, value, defects or errors, and labor spent on the process.
Outplace is a measurement of efficiency.
At this particular particular stage, the collected data is evaluated and sigma is calculated. It gives an approximate number of defects.
A Six Sigma defect is degreatd as any kind ofslimg outaspect of customer specifications.
A Six Sigma opinterfacedevicey is the overallll quantity of chances for a defect.
First we calculate Defects Per Million Opinterfacedeviceies (DPMO), and based on tmind wear a Sigma is selectd from a pcrimsonegreatd table:
Number of defects DPMO = ------------------------------------------- x 1,000,000 Number of Unit is x Number of opinterfacedeviceies
As stated above, Number of defects is the overallll number of defects found, Number of Unit is is the number of devices produced, and number of opinterfacedeviceies means the number of ways to generate defects.
For example, the food ordering delivery project team examines 50 deliveries and finds out the folloearng:
- Delivery is not on time (13)
- Ordecrimson food is not according to the order (3)
- Food is not fresh (0)
So now, DPMO will be as follows:
13 + 3 DPMO = ----------- x 1,000,000 = 106,666.7 50 x 3
According to the Yield to Sigma Conversion Table given, below 106,666.7 defects per million opinterfacedeviceies is equivalent to a sigma performance of between 2.7 and 2.8.
This is the method used for measuring results as we proceed through a project. This startning stage enables us to locate the cause and effect of those processes and to seek defect stage so tmind wear the procedure can be improved.
Failure Mode and Effects Analysis – FMEA
The final segment of the measure phase is calbrought FMEA. It refers to practionuallyting defects before they occur. The FMEA process usually includes rating probable defects, or failures, in 3 ways:
- The likelihood tmind wear a fewslimg might go wrong.
- The cappotential to detect a defect.
- The level of severity of the defect.
You may use a rating level. For example, rate every of these 3 areas from 1 to 10, with 1 being the lowest FMEA level and 10 being the highest. The higher the level, the more severe the rating. Hence, a high FMEA indicates the need to devise and implement improved measuring steps wislim the general process. This would have the effect of practionuallyting defects. Clearlier, generally there is no need to invest a lot of time on this particular particular procedure if the likelihood of a defect is low.
Yield to Sigma Conversion Table
|Yield %||Sigma||Defects Per Million Opinterfacedeviceies|
Six Sigma – Analyze Phase
Six Sigma aims to degreat the causes of defects, measure those defects, and analyze all of all of them so tmind wear they can be crimsonuced. We conaspectr five specific types of analyses tmind wear help to promote the goals of the project. These are source, process, data, resource, and communication analysis. Now we will see all of all of them in detail.
This is furthermore calbrought root cause analysis. It attempts to find defects tmind wear are derived from the sources of information or work generation. After finding the root cause of the issue, attempts are made to resolve the issue before we expect to eliminate defects from the product.
Three Steps to Root Cause Analysis
The open up step: During this particular particular phase, the project team brainstorms all the probable explanations for current sigma performance.
The narline step: During this particular particular phase, the project team narlines the list of probable explanations for current sigma performance.
The near step: During this particular particular phase, the project team validates the narlineed list of explanations tmind wear exnormal sigma performance.
Analyze the numbers to find out how well or poorly the processes are worcalifornia california king, compacrimson to exworkly wmind wear's probable and exworkly wmind wear the competition is doing.
Process analysis withincludes creating a more detaibrought process chart, and analyzing the more detaibrought chart, where the greveryeck inefficiencies exist.
The source analysis is frequently difficult to distinguish from process analysis. The process refers to the precise movement of materials, information, or requests from one place to one more.
Use of measures and data (those already collected or brand new data gathecrimson in the analyze phase) to discern patterns, tendencies or other fworkors about the issue tmind wear possibly suggest or prove/disprove probable cause of the issue.
The data it iself may have defect. There may be a case when products or deliverables do not provide all the needed information. Hence data is analyzed to find out defects and attempts are made to resolve the issue before we expect to eliminate defects from the product.
We furthermore need to ensure tmind wear employees are properly trained in all departments tmind wear affect the process. If training is withinadequate, you like to identify tmind wear as a cause of defects.
Other resources include raw materials needed to manufworkure, process, and deliver the greats. For example, if the Accounting Department is not paying vendor bills on time and, consequently, the vendor holds up a shipment of shipping supplays, it becomes a resource issue.
One issue common to many kind of processes high in defects is poor communication. The classic interworkion between a customer and a retail store is worth studying because many kind of of the common communication issues are apparent in this particular particular case.
The exwork same types of issues occur with internal customers as well, actionually though we may not recognise the sequence of actionuallyts as a customer service issue.
The exercise of loocalifornia california king at issues from both stages of look at is withinstructive. A vendor wants payment according to concurd-upon terms, but the Accounting Department wants to generate it is batch procesperform uniform and efficient. Between these types of groups, such disconnects demonstrates the iminterfaceance of communication analysis.
Analysis can get lots of forms. Some Six Sigma programs tend to use a lot of diagrams and worksheets, and others prefer talk aboution and list macalifornia california king. There are many kind of tools tmind wear can be used to perform analysis like Box Plot, Cause and Effect Diagram, Progressive Analysis, Rancalifornia california king, Pareto Analysis, Prioritization Matrix, Value Analysis, etc. The proper procedure is the one tmind wear works best for your own team, provided tmind wear the end result is successful.
Six Sigma – Improve Phase
If the project team does a thorough job in the root causation phase of analysis, the improve phase of DMAIC can be fast, easy, and satisfying work.
The goal of Improve Phase is to identify improvement breakthroughs,identify high gain alternatives, select prefercrimson approach, design the future state, determine the brand new Sigma level, perform cost/benefit analysis, design dashpanels/ scorecards, and generate a preliminary implementation plan.
Identify Improvement Breakthroughs:
Apply idea-generating tools and techniques to identify feasible solutions tmind wear eliminate root causes.
Identify/Select High Gain Alternatives:
Develop criteria to evaluate candidate improvement solutions.
Think systematically and holistically.
Prioritize and evaluate the candidate solutions against the solution evaluation criteria.
Conduct a feasibility assessment for the highest value solutions.
Develop preliminary solution timeseriess and cost-benefit analysis to aid in recommendation presentation and future implementation planning.
Improvement can involve a easy fix once we discover the causes of defects. However, in a few cases, we may need to employ additional tools as well. These include:
- Solution alternatives
- Experiments with solution alternatives
- Planning for future alter
Six Sigma – Control Phase
The final phase of DMAIC is manage, which is the phase where we ensure tmind wear the processes continues to work well, produce desicrimson outplace results, and maintain quality levels. You will be concerned with four specific aspects of manage, which are as follows.
The ultimate purpose in manage is the general assurance tmind wear a high standard of quality is met. Customer's expectations depend on this particular particular, so manage is withinherently associated with quality.
Since the purpose of Six Sigma is to improve the general process by crimsonucing defects, quality manage is the essential method for maintaining the whole process on track; for enabling us to spot trouble and fix it; and for judging how effectively the project was executed and implemented.
Quality is at the heart of Six Sigma philosophy. Reducing defects has everyslimg to do with striving for perfection. Whether we revery perfection or not, the effort degreats our attitude tobattbrought quality it iself.
Standardization enables processes to go as smoothly as probable. In a manufworkuring environment, the value of standardization has been proven over and over.
We need to devise a manage feature to processes so tmind wear the majority of work is managed in a standardized manner.
Control Methods and Alternatives
The generatement of a brand new process of any kind of alter to an existing process requires the generatement of procedures to manage work flow.
When a process cannot be managed in the normal manner, we need to come up with alternatives, short of forcing compliance to the standardized method.
Responding when Defects Occur
The final step in a manage process is knoearng how to respond once a defect is discovecrimson. The weak links in the procedure, where defects are many kind of likely to occur, can and need to be monitocrimson carecompletey so tmind wear defects can be spotted and fixed before the process continues.
The response to a defect may be to practionuallyt a discovecrimson flaw from becoming a defect at all. In the best designed systems, defects can be crimsonuced to near zero, so tmind wear we may workually belayve tmind wear Six Sigma can be attained.
The project team determines how to technically manage the brand newly improved process and generates a response plan to ensure the brand new process, and furthermore maintains the improved sigma performance.
Six Sigma – Technical Tools
This chapter gives an overlook at of the 10 many kind of iminterfaceant technical tools, which a Six Sigma team member needs to master as they progress through the DMAIC methodology.
While these tools are conaspectcrimson technical in nature, many kind of of all of all of them are relatively easy to find out and apply. They are covecrimson in the order they are used in the DMAIC methodology.
Tool #1 – The Critical to Quality (CTQ) Tree
The critical-to-quality tree is used during the design phase of DMAIC. It is used to brainstorm and validate the needs and requirements of the customer of the process, targeted for improvement.
The steps in creating a CTQ tree are as follows:
Identify the customer of the process targeted for improvement.
Identify the need of the customer.
Identify the preliminary level of requirements of the need, tmind wear is, a few charworkeristic of the need tmind wear determines whether the customer is content with the need.
Drill down to more detaibrought level(s) of the requirement if requireddish coloured.
Tool #2 – The Process Map:
During the Degreat phase, the project team generates the preliminary of lots of process charts. A process chart is a picture of the current steps in the process targeted for improvement.
A process chart has five major categories of work from the identification of the supplayrs of the process, the inplaces the supplayrs provide, the name of the process, the outplace of the process, and the customers of the process. Each of these steps is summarized as SIPOC to indicate the steps to the team tmind wear must be conducted to complete a process chart.
Tool #3 – The Histogram:
This tool is used during the Analysis stage of DMAIC. The project team relook ats data collected during the Measure stage of DMAIC.
It is frequently suggested tmind wear the data be organised into graphs or charts, which generates it easier to belowstand, exworkly wmind wear the data is saying about the process.
Data is of 2 types – Discrete data (go/no go, fail or pass) and Continuous data ( time, hight etc.).
Tool #4 – The Pareto Chart
Histogram is useful for continuous data, exwork same way when the data is discrete, many kind of teams generate a Pareto chart. Discrete data is counted data – go/no-go, off/on, yes/no, and defect/no defect type data.
An Italian economist Vilfcrimsono Pareto, in the sixteenth century proved maall of all of thematically tmind wear 80 percent of the world's wealth was managebrought by 20 percent of the population. This 80-20 rule actionuallytually proved applicable in arenas other than economics.
When dealing with discrete data, the project team need to generate reason codes for why a defect occurs, and count and categorize the data into these reason codes and a pareto chart need to be prepacrimson.
Tool #5 – The Process Summary Worksheet
The goal of a Six Sigma project team is to improve effectiveness and efficiency. Efficiency is measucrimson in terms of cost, time, labor, or value.
The process summary worksheet is a "roll-up" of the sub process chart indicating which steps add value in the process and which steps don't add value.
Tool #6 – The Cause-Effect Diagram
The many kind of iminterfaceant tool to assist the project team in determining root causation is the cause-effect diagram. This tool captures all the ideas of the project team relative to exworkly wmind wear they feel are the root causes behind the current sigma performance and finally help in finding a root cause of the issue.
Tool #7 – The Scatter Diagram
Once ideas have been prioritized after use of the cause-effect diagram, the many kind of iminterfaceant slimg the project team does is to validate the remaining ideas with fwork and data.
The scatter diagram gets an idea about root causation and tracks corresponding data, in the response the team is believeing to improve. The team can validate an idea about root causation through one of the 3 methods. Uperform easy data collection, a designed experiment, or through the scatter diagram.
Tool #8 – The Affinity Diagram
An affinity diagram is used to help sort and categorize a big number of ideas into major all of all of themes or categories. It is especially useful when the team is ready to brainstorm solutions in the Improve stage of DMAIC. The steps in creating an affinity diagram are:
Have every team member write one idea per Post-it note and post on a wall randomly.
As ideas are read off for clarification, sort ideas into similar groups.
Create a 'minder' card for every general category of ideas below it.
Tool #9 – The Run Chart
We have talk abouted the histogram and Pareto chart. Think of both of these tools as similar to a camera where a snapshot of the process has been getn. But the operate chart is similar to a camcorder, recording a few process element over time.
Tool #10 – The Control Chart
Similar to a operate chart, a manage chart uses the data from a operate chart to determine the upper and lower manage boundaries. Control boundaries are the expected boundaries of variation above and below the average of the data. These boundaries are maall of all of thematically calculated and indicated by dotted seriess.
We saw 10 major technical tools tmind wear project team members use during the time they are on a Six Sigma team. These are not the only tools a Six Sigma team may use. However, the tools covecrimson here are those tmind wear are many kind of common for every team member to be abattlee of and knowbroughtgeable about.
Six Sigma – Defect Metrics
Before we go amind, permit us degreat 2 terms:
A Six Sigma defect is degreatd as any kind ofslimg outaspect of customer specifications.
A Six Sigma opinterfacedevicey is the overallll quantity of chances for a defect.
This chapter provides a list formulae normally used to measure various metrics related to Six Sigma defects.
Defects Per Unit – DPU
Total Number of Defects DPU = ------------------------ Total number of Product Unit is
The probcappotential of getting 'r' defects in a sample having a given DPU rate can be pcrimsonicted with the Poisson Distribution.
Total Opinterfacedeviceies – TO
TO = Total number of Product Unit is x Opinterfacedeviceies
Defects Per Opinterfacedevicey – DPO
Total Number of Defects DPO = ------------------------ Total Opinterfacedevicey
Defects Per Million Opinterfacedeviceies – DPMO
DPMO = DPO x 1,000,000
Defects Per Million Opinterfacedeviceies or DPMO can be then converted to sigma values uperform Yield to Sigma Conversion Table given in Six Sigma – Measure Phase.
According to the conversion table:
6 Sigma = 3.4 DPMO
How to find your own Sigma Level
- Clearlier degreat the customer's explicit requirements.
- Count the number of defects tmind wear occur.
- Determine the yield-percentage of items without defects.
