Notas do Editor
- This slide not only looks at the impact of quality on productivity - it also enables you to begin a discussion as to the meaning of quality (or perhaps the differing meanings among different people). To many people, the notion of “high quality” carries with it the assumption of “high price.” This slide provides an initial point to challenge that assumption.
- This slide simply introduces the four activities. Subsequent slides expand on each.
- One might begin discussion of this slide by introducing the difference between “leadership” and “management.” The point should also be made, again, about the need for involvement and commitment throughout the organization.
- Some students may find the notion of “continuous improvement” (Why can’t we do it right the first time?) and “employee empowerment” (Doesn’t this reduce or abrogate the role of the manager?) the most difficult to accept. If you have not done so already, this might be a good time to discuss each in some depth. The following slide may be used in a discussion of empowerment.
- This slide can be used to form the basis for a discussion of empowerment. If you wish to discuss empowerment - begin by asking students to define the term. You may find students are already comfortable with the term, in which case the discussion can be rather short; or, you may find they have unrealistic expectations (or desires?) - in which case you may wish to pursue the discussion at greater length. It may be helpful to ask students to identify the benefits and pitfalls to both management and worker. (For example, empowerment requires workers to assume greater responsibility.)
- The main point that one might make with this slide is that the customer is, ultimately, the most important person in your business.
- Once you have introduced these definitions of quality, ask students to provide example of products that use them.

- Although the text considers service quality at the end of the chapter, you may wish, at this point, to contrast the notion of quality for goods with that for services. If not, skip this slide - it is repeated at the point at which the issues are raised in the text.
- This slide simply illustrates the relationships between quality and other elements of the firm.
- Students might be asked what problems they would foresee in implementing this process.
- A point to be made here is that TQM is not a program but a philosophy.
- Again, a point to be made here is the universality required to achieve TQM.
- One point to make here is that this list represents a recent expression of Demings 14 points - the list is still evolving. Students may notice that many of these fourteen points seem to be simply common sense. If they raise this issue - ask them to consider jobs they have held. Were these points emphasized or implemented by their employers? If not, why not? This part of the discussion can be used to raise again the issue that proper approaches to quality are not “programs,” with limited involvement and finite duration, but rather philosophies which must become ingrained throughout the organization.
- At this point, you might consider going back to the slides illustrating the differences between goods and services. Those slides are provided next. If you do not wish to use them, simply skip to the final slide in the sequence.
- This slide is a repeat of the earlier one on Service Quality Attributes as that topic appears at this point in the text.
