6 Sigma

Manzoor Ahmed

What is 6σ? Methodology Developed by Bill Smith,

Motorola, 1986 Eliminates Defects, Improves Processes <3.4 Defects per million opportunities (DPMO) Only 2 yrs after launching 6σ, motorola was honored Malcolm Baldrige Quality Award

DEFINATION A comprehensive & flexible system for

achieving, sustaining and maximizing business success. SIX SIGMA is uniquely driven by close understanding of customer needs, disciplined use of facts, data and statistical analysis, and diligent attention to managing, improving and reinventing business processes.

Benefits of SIX SIGMA Generates sustained success. Sets a performance goal for everyone. Enhances value to customers. Accelarate the rate of improvement. Promotes learning and cross pollination. Executes strategic change.

6 Themes of Six Sigma Genuine focus on the customer. Data and fact driven management. Process focus, management and

improvement. Proactive management. Boundryless collaboration. Drive for perfection, Tolerance for failure.

Implemented Cases The Dabbawallahs

Case2: Wipro  CFP  DSSS+ (Developing Six Sigma Software) - Software

Development  DSSP (Designing Six Sigma Process & Product) –Software Development  DCAM (Design for Customer Satisfaction and Manufacturability)-Hardware design & Manufacture  DMAIC (Define, Measure, Analyze, Improve, Control) Helpdesk, Infra support, Call centre  TQSS (Transactional Quality Using Six sigma)- defect reduction  CFPM (Cross Functional Process Mapping) - Cross functional streamlining of process

Terminology Green Belts (GB)- trained in Six Sigma who

spend a portion of their time completing projects, but maintain their regular work role and responsibilities. Depending on their workload, they can spend anywhere from 10% to 50% of their time on their project(s).  Black Belts (BB) -the experts in Six Sigma methodologies and its usage. Black Belts are the heart and soul of the Six Sigma quality initiative. Their main purpose is to lead quality projects and work full time until they are complete. Black Belts can typically complete four to six projects per year with savings of approximately $230,000 per year. Champions: Facilitate the leadership, implementation and deployment of Six Sigma

Case2: Wipro Evolution  1stIndian company to adopt Six Sigma in 1999  91% of the projects completed on schedule, much above the

industry average of 55%.  Across verticals and impacts multiple areas such as project management, market development and resource utilization.  A measure of quality that strives for near perfection.  An umbrella initiative covering all business units and divisions so that it could  transform itself in a world class organization.  (i) Have products and services meet global benchmarks  (ii) Ensure robust processes within the organization  (iii) Consistently meet and exceed customer expectations  (iv) Make Quality a culture within.

Difficulties Encountered Build the Culture Project selection Training Resources Project Reviews

Benefits of implementing six sigma Manufacturing sector Financial sector Research and development sector Better SCM  quantitative understanding, cost savings, and

performance improvement towards product quality Reduce the data transfer time Reduce the risk Avoid interruption due to LAN/WAN downtime. Parallel availability of the switch for the other administrative tasks during the same period.

Limitations of six sigma Time consuming Resource constrain Statistical knowledge Suppresses creativity Lack of Originality

Future? Can be applied to every business process of

an organization. Growing awareness in small and medium enterprises Need for systematic innovation
