Quality is a state in which value entitlement is realized for the customer and provider in every aspect of the business relationship.

Business Quality is highest when the costs are at the absolute lowest for both the producer & consumer.

Six Sigma provides maximum value to companies in the forms of increased profits and maximum value to consumers with high-quality products and services at the lowest possible cost.

Defect is any process output that does not meet customer specifications, or that could lead to creating an output that does not meet customer specifications.

Cost of Poor Quality (COPQ) is the cost that would disappear if systems, processes, and products were perfect.

Process & Process Capability

Process is a unique combination of tools, materials, methods, and people engaged in producing a measurable output; for example a manufacturing line for machine parts. All processes have inherent stastical variability which can be evaluated by statistical methods.

The Process Capability is a measurable property of a process to the specification, expressed as a process capability index (e.g., Cpk or Cpm) or as a process performance index (e.g., Ppk or Ppm). The output of this measurement is usually illustrated by a histogram and calculations that predict how many parts will be produced out of specification (OOS).

Process capability is also defined as the capability of a process to meet its purpose as managed by an organization's management and process definition structures ISO 15504.

Two parts of process capability are: 1) Measure the variability of the output of a process, and 2) Compare that variability with a proposed specification or product tolerance.

Six Sigma is a Business PhilosophySix Sigma is a Business Philosophy

Six Sigma

Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects in any process -- from manufacturing to transactional and from product to service.

To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities (DPMO).

A Six Sigma opportunity is then the total quantity of chances for a defect. Customer focused business improvement process. Defect reduction in a process or product. Common measurement scale called the Sigma capability or Z. Six Sigma capability corresponds to an efficiency of 99.9996%. 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.) who are experts in these methods.

Six Sigma was developed by Bill Smith, QM at Motorola It’s implementation began at Motorola in 1987 It allowed Motorola to win the first Baldrige Award in 1988 Several major companies in the world have adopted Six Sigma

since then .…and applied to Manufacturing processes to improve product quality

Texas Instruments, Asea Brown Boveri, AlliedSignal, General Electric, Bombardier, Nokia Mobile Phones, Lockheed Martin, Sony, Polaroid, Dupont, American Express, Ford Motor,…….

GE applied the Six Sigma methodology to improve all business processes and it became a way of running the business.

What is Sigma

Sigma (upper case Σ, lower case σ) is the eighteenth letter of the Greek alphabet.

In the system of Greek numerals it has a value of 200.

Sigma is used to show standard variation. In probability theory and statistics, the standard deviation of a

statistical population, a data set, or a probability distribution is the square root of its variance.

It shows how much variation there is from the "average" (mean). A low standard deviation indicates that the data points tend to

be very close to the mean, whereas high standard deviation indicates that the data are spread out over a large range of values.

Six Sigma - MethodologiesThere are two Six Sigma sub-methodologies:

DMAIC and DMADV.

The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement.

The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to develop new processes or products at Six Sigma quality levels.

Both Six Sigma processes are executed by Six Sigma Green Belts and Six Sigma Black Belts, and are overseen by Six Sigma Master Black Belts.

18

Six Sigma - DMAIC Vs DMADV

DMAIC Define the project goals and

customer (internal and external) deliverables

Measure the process to determine current performance

Analyze and determine the root cause(s) of the defects

Improve the process by eliminating defects

Control future process performance

When To Use DMAIC The DMAIC methodology should be

used when a product or process is in existence at your company but is not meeting customer specification or is not performing adequately.

DMADV Define the project goals and customer

(internal and external) deliverables Measure and determine customer

needs and specifications Analyze the process options to meet

the customer needs Design (detailed) the process to meet

the customer needs Verify the design performance and

ability to meet customer needs

When To Use DMADV A product or process is not in

existence at your company and one needs to be developed

The existing product or process exists and has been optimized (using either DMAIC or not) and still doesn't meet the level of customer specification or six sigma level

Where to apply…..

Example - Pizza Delivery Service

XYZ a fast food company, owned by Mr. ABC, runs a pizza delivery service in and around Delhi. XYZ which was doing very well over the last four years, notices a drop in sales over the past five months. Customer complaints about deliveries have been gradually on the rise. Several complaints from customers regarding irregular deliveries were bothering ABC. He had increased the number of delivery personnel to improve delivery performance. But his customers were still leaving him. Pizza Hut, a multinational fast food chain, had set up shop in downtown and was becoming more popular with the customers. XYZ neither had the financial muscle to match Pizza Hut’s advertising blitz nor could afford the expensive packaging to lure his customers back.

1. How does the customer view XYZ Quality?

2. Who are the stakeholders - Customer and Process Improvement Team?

3. Which of his processes should he try to improve in order to improve Sales?

A. IDENTIFY CTQ CHARACTERISTICS

Translate the CTQ to a measurable output of the delivery process

Delivery time can be measured in many ways:

1. No. of times the delivery person delivered during the shipping window (Discrete measure)2. Time taken to travel from XYZ location to customer location (Continuous measure)3. Actual delivery time as seen by customer (Continuous measure)

Delivery time is the Project Y.

The Measure Phase - Step A

The Measure Phase - Summary

A data collection plan is done in the Measure phase. It sets the expectations for the project. This phase is owned by the Project Leader. The three steps of the Measure phase are:

1. Identify CTQ characteristic2. Define Performance Standards3. Evaluate Measurement System

The list of tools available for the Measure phase are:

Brainstorming, PMAP, FMEA, MSE, GR&R, C&E Diagram or Fishbone, Quality Function Deployment or QFD, Prioritization Matrix,

CREATING A HISTOGRAM:Using the concept of the late and early deliveries, take the target time as the reference, and find the number of minutes by which each delivery is late or early.

1. Subtract Target time for each data point from the Delivery time

2. Define 5 predetermined bins (class intervals) of size equal to 10 minutes, from -25 to 25 on a horizontal line

3. Place each data point vertically in a bin according to its value

4. Draw a bar equal to the height of stacked up points
