    What is Total Quality Management (TQM)?

    A philosophy that involves everyone in an organisation in a

    continual effort to improve quality and achieve customer

    satisfaction.

    Encompasses entire organization, from supplier tocustomer

    Stresses a commitment by management to have acontinuing, companywide drive toward excellence in allaspects of products and services that are important to the

    customer.

    Principles of Total Quality

    1. Focus on the customer (Both internal &external

    2. Participation and Team work

    3. Employee involvement and empowerment4. Continuous improvement and learning.

    A program designed to reduce defects,lower costs, and improve customer

    satisfaction

    Six Sigma

  • 7/30/2019 OM Lecture 23

    9/34

    Six Sigma

    1. Define critical outputsand identify gaps forimprovement

    2. Measure the work andcollect process data

    3. Analyze the data

    4. Improve the process

    5. Control the new process tomake sure new performance ismaintained

    DMAIC Approach

    Employee Empowerment

    Getting employees involved in product andprocess improvements

    85% of quality problems are due to process

    and material Techniques

    Build communication networks that

    include employees

    Develop open, supportive supervisors

    Move responsibility to employees

    Build a high-morale organization

    Create formal team structures

  • 7/30/2019 OM Lecture 23

    Quality Circles

    Group of employees who meetregularly to solve problems

    Trained in planning, problemsolving, and statistical methods

    Often led by a facilitator

    Very effective when done properly

    Taguchi Concepts

    Engineering and experimental designmethods to improve product andprocess design

    Identify key component and processvariables affecting product variation

    Taguchi Concepts

    Quality robustness

    Quality loss function

    Target-oriented quality

  • 7/30/2019 OM Lecture 23

    13/34

    Quality Robustness

    Ability to produce products uniformly inadverse manufacturing and environmentalconditions

    Remove the effects of adverse conditions Small variations in materials and process do

    not destroy product quality

    2. Seitonputting things in orderEverything should be in itsplace and there should be place for everything (good house

    keeping)3. Seiso clean-upEvery individual should clean-up his

    work place everyday after the work.

    Quality Circles (QC)

    Quality circle: A small group of employees who meet

    regularly to undertake work-related projects designed to

    improve working conditions, spur mutual self-development

    and to advance the company, all by using quality control

    concepts.

    Quality Certification

    Quality Systems A quality system is defined as "The collectiveplans, activities and

    events that are provided to ensure that a product, process or

    service will satisfy given needs".

    International Quality Standards

    ISO 9000: A set of international standards on quality management

    and quality assurance, critical to international business

    ISO 14000: A set of international standards for assessing a

    companys environmental performance.

  • 7/30/2019 OM Lecture 23

    29/34

    ISO 9000

    Series of standards agreed upon by the InternationalOrganization for Standardization (ISO)

    Adopted in 1987 More than 100 countries

    A prerequisite for global competition?

    ISO 9000 directs you to "document what you do andthen do as you documented"

    ISO 14000: Environmental Standard

    Core Elements:

    Environmental management

    Auditing

    Performance evaluation

    Labeling

    Life cycle assessment

    ISO 9001 : 2000

    The Indian standard (second revision) which is identical with ISO9001 : 2000 "Quality Management Systems Requirements" issued

    by International organisation for standardisation (ISO) was adopted

    by the Bureau of Indian Standards (BIS) on the recommendation of

    the Quality Management Sectional Committee and approval of the

    Management and Systems Division Council.

    Process Approach

    ISO 9001 : 2000 promotes the adoption of a process approachwhen developing, implementing and improving the effectiveness

    of a quality management system, to enhance customer satisfaction

    by meeting customer requirements.

  • 7/30/2019 OM Lecture 23

    32/34

    Three Forms of ISO Certification

    1. First party: A firm audits itself against ISO 9000

    standards

    2. Second party: A customer audits its supplier

    3. Third party: A "qualified" national or international

    standards or certifying agency serves as auditor
