Process Improvement Goals

Process Goals

Improve Schedule and budget predictability

Improve cycle time/time to market

Increase productivity

Improve quality (as measured by defects)

Increase customer satisfaction

Improve employee morale

Decrease cost of quality

Companies want to increase return on investment

Six Sigma; What is it? According to David Card, (IEEE Software 2000), Six

sigma is A generic quantitative approach to

improvement that applies to any process.

Six Sigma is a disciplined, data-driven approach and

methodology for eliminating defects (driving towardssix standard deviations between the mean and the

nearest specification limit) in any process -- from

manufacturing to transactional and from product to

service.

Six Sigma Levels

Six Sigma can be identified at three levels:

Metric

Methodology

Philosophy


7/20

Metric 3.4 Defects Per Million

Opportunities (DPMO)

DPMO allows you take complexityof product/process into account

Most companies are within 3standard deviations of the mean


8/20

Metric

The higher thesigma value, the

better the process

is capable of

producing defect

free results

To be in this six

sigma range youmust have a

quality product

99.9999998% of

the time.


9/20

Philosophy

Reduce variation in your business and

make customer-focused,

data driven decisions

Translate customer needs intooperational measurements


10/20

Methodology Structured problem solving techniques and

roadmap

Two primary sub-methodologies in Six Sigma DMAIC

DMADV


11/20

DMAIC

Define-Measure-Analyze-Improve-Control

Tool for incremental process improvement of

existing processes within an organization that fall

below required specification


12/20

DMAIC(cont.) Define

Define the problem or process to improve upon related to thecustomer and goals

Measure How can you measure this process in a systematic way?

Analyze Analyze the process or problem and identify the way in which it can

be improved. What are the root causes of problems within theprocess?

Improve Once you know the causes of the problems, present solutions for

them and implement them

Control Utilize Statistical Process Control to continuously measure your

results and ensure you are improving

Several Software Packages available to assist in measuring yield,defects per million opportunities, etc.


13/20

DMADV Define-Measure-Analyze-Design-Verify Methodology for producing new processes that

meet the Six Sigma Quality levels desired

Similar to DMAIC, however, we have a design

stage here DFSS

Design-For-Six-Sigma

Using models or prototypes to create designs and

ensure they are effective in meeting goals


14/20

DMAIC vs. DMADV


15/20

Six Sigma Personnel Champion

Manager/Director/Executive whomakes sure the resources are inplace for a Six Sigma project

Master Black Belts Quality experts in an organization Responsible for strategic implementation

Teach/Mentor other Black and Green Belts

Black Belts Six Sigma team leaders responsible for implementing process

improvement projects within the business

Green Belts Employee of an organization that has some training in Six

Sigma and may lead a Six Sigma project, but only as part oftheir job


16/20

Six Sigma Strengths

Generic Process Improvement Strategy can beapplied to any process

Trained personnel working on process

improvements for organization on continuous

basis


17/20

Six Sigma Weaknesses Derived from manufacturing which has a real tangible

process that is easy to measure and apparent, asopposed to software engineering

No formal connection to ISO 9000 ISO 9000 and CMM have milestones and certifications

Six Sigma relies on training personnel (black belts)that look for areas that need improvement which maynot be the best way to go about this Costs also involved in training for Six Sigma

Focuses on Internal process experience and doesntconsider external technology or best practices


18/20

Difference between Six Sigma Projects

and Typical Software projects

According to Zhedan Pan, Hyuncheol Park, the sixsigma projects and typical software projects can be

differentiated by the following parameters:

Start

Team

Objectives

Processes

Toolkits
