    The more significant changes to requirements in ISO/TS 16949:2002 are :

    Requirement to define Quality Objectives and Targets (clause 5.4.1.1)

    Increased requirements for Management Review (clause 5.6)

     Determination of employee competence (clause 6.2.2) and employee motivation & empowerment (clause 6.2.2.4)

    Inclusion of requirements for Process Design (clause 7.3)

    Enhanced Supplier Development and Supplier Monitoring requirements (clause 7.4

    Enhanced Customer Satisfaction requirements (clause 8.2.1.1)

    Well  6-Sigma is a subset of TQM and I agree to this fact , if you look into the philosophy of TQM /just the way TQM is defined it says ,”Total Quality Management (TQM) is a management approach that aims for long-term success by focussing on customer satisfaction. TQM is based on the participation of all members of an organization in improving processes, products, services, and the culture/society in which they work.
     
    Sigma refers to a measurement of how far a given process deviates from perfection. Achieving Six Sigma quality requires producing no more than 3.4 defects per million opportunities for quality in meeting customer specifications. Six Sigma is a methodology for eliminating defects through process improvement, and its practices ensure repeatable success.
     Hence six sigma is very narrowly focused on to just a process, it can rather be called as a process improvement tool, with specific time lines & objective.

    Hi ,
    You are trying to compare a tumour cell with a normal cell , in that case its a One -to – Standard value comparision i.e single sample comparision , hence U need to use a t-test

    Hi Anjali,
    Your problem is quite simple when ever you are stating your requirement yo should mention your specification limits i.e. USL & LSL , a supplier having  SPC experiece has to fix his production within the spec limits which you have mentioned i.e. his UCL & LCL so to have a good capable process he should have his Cp & Cpk  values of 1.33 or higher .
    Cp is a ratio of the customer specification tolerance to six standard deviation of the short term process variation.
    Cpk is a ratio of the diatance between the process average and the closest specification limit , to 3 standard deviations of a short term process variation , it is often refered to as process performance.

    Hi,
    I do understand the nature of your industry its basically  a manual job or an art . You must understand the fundamental saying that “Thing  which cannot be measured ,can’t be improved “. so without measures you cannot use any statistical tools.

    I do agree with your views , P-chart are used where you have propotions defectives type of data, and when the sample size is variable in nature. Some basic things which people forget is the common confusion in identifing Defect & Defectives.
    Defects : Refer to any Non compliance to specification
    Defective: A sample /product having >=1 defects can be termed as defective
    If you can send in some data …..it will help in more clarity…

    Hi,
    It would be a difficult to estimate the exact number of ISO 9001:2000 certified hospitals in India , but it I know amy hospitals where Six sigma initatives have been take ….it may not be on a very  formal basis but the goals and objectives remains same ? For Ex. Hinduja Hospital in Mumbai , Appolo hospital , to name a few

    In some aspects of quality improvement, TQM and Six Sigma share the same philosophy of how to assist organizations to accomplish Total Quality. They both emphasize the importance of top-management support and leadership. Both approaches make it clear that continuous quality improvement is critical to long-term business success. However, why has the popularity of TQM waned while Six Sigma’s popularity continues to grow in the past decade?
     Unlike TQM, Six Sigma was not developed by technicians who only dabbled in management and therefore produced only broad guidelines for management to follow. The Six Sigma way of implementation was created by some of America’s most gifted CEOs – people like Motorola’s Bob Galvin, Allied Signal’s Larry Bossidy, and GE’s Jack Welch. These people had a single goal in mind: making their businesses as successful as possible. Once they were convinced that tools and techniques of Six Sigma could help them do this, they developed a framework to make it happen.
    The differences between TQM and Six Sigma are summarized in the table mentioned below
    TQM vs. Six Sigma

    TQM

    Six Sigma

    A functional specialty within the organization.

    An infrastructure of dedicated change agents.  Focuses on cross-functional value delivery streams rather than functional division of labour.

    Focuses on quality.

    Focuses on strategic goals and applies them to cost, schedule and other key business metrics.

    Motivated by quality idealism.

    Driven by tangible benefit far a major stockholder group (customers, shareholders, and employees).

    Loosely monitors progress toward goals.

    Ensures that the investment produces the expected return.

    People are engaged in routine duties (Planning, improvement, and control).

    “Slack” resources are created to change key business processes and the organization itself.

    Emphasizes problem solving.

    Emphasizes breakthrough rates ofimprovement.

    Focuses on standard performance, e.g. ISO 9000.

    Focuses on world class performance, e.g., 3.4 PPM error rate.

    Quality is a permanent, full-time job. Career path is in the quality profession.

    Six Sigma job is temporary. Six Sigma is a stepping-stone; career path leads elsewhere.

    Provides a vast set of tools and techniques with no clear framework for using them effectively.

    Provides a selected subset of tools and techniques and a clearly defined framework for using them to achieve results (DMAIC).

    Goals are developed by quality department based on quality criteria and the assumption that what is good for quality is good for the organization.

    Goals flow down from customers and senior leadership’s strategic objectives. Goals and metrics are reviewed at the enterprise level to assure that local sub-optimization does not occur.

    Developed by technical personnel.

    Developed by CEOs.

    Focuses on long-term results. Expected payoff is not well-defined.

    Six Sigma looks for a mix of short-term and long-term results, as dictated by business demands.

    Critical to Quality Requirement is Retention of employees & Attrition is the metric to be tracked for improvement.

    Well I have consulted a number of hospitals and applied six sigma methodologies in improving the patient waiting time, Improving the overall satisfaction level of internal & external customer.
    You can contact me for further information on these areas..

    Errors in a  contract or a document or for the matter in a book follows Poisson distribution hence the user should take into consideration the properties of Poisson distribution before taking any samples , and there after use relevent statiatical tools.

    TQM is a holistic approach which goes beyond a organisation ,its a philosophy where as Six sigma  is a focussed approach to solve a problem  on a project basis . Hence in my opinion we cannot compare these two approaches.

    Well Its is not worth while comparing both because six sigma is just a methodolgy  for focused improvements,where as TQM is a philosophy in simple terms a bigger domain .
