21. Overview of
ISO 9001 and
ISO 14001

22. ISO 9001 and ISO 14001 in
brief
 ISO 9001 and ISO 14001 are among ISO's most well
known standards ever.
 They are implemented by more than a million
organizations in some 175 countries.
 ISO 9001 helps organizations to implement quality
management.
 ISO 14001 helps organizations to implement
environmental management.

23.  ISO 9001 is for quality management
 Quality management means what the organization
does to :
 ensure that its products or services satisfy the
customer's quality requirements and
 comply with any regulations applicable to those
products or services.
 enhance customer satisfaction, and
 achieve continual improvement of its performance

24.  ISO 14001 is for environmental management. This
means what the organization does to:
 minimize harmful effects on the environment caused
by its activities,
 to conform to applicable regulatory requirements, and
to
 achieve continual improvement of its environmental
performance.

25. Processes, not products
 Both ISO 9001 and ISO 14001 concern the way an
organization goes about its work.
 They are not product standards.
 They are not service standards.
 They are process standards.
 They can be used by product manufacturers and
service providers.

26. Processes, not products
(cont.)
 Processes affect final products or services.
 ISO 9001 gives the requirements for what the
organization must do to manage processes affecting
quality of its products and services.
 ISO 14001 gives the requirements for what the
organization must do to manage processes affecting
the impact of its activities on the environment.

49. What is Ethics
Ethics involves
 Having guidelines for human behavior
 Studying moral choices and values
 Choosing between right and wrong

50. What is ethical behaviour
 Ethics
 Code of moral principles.
 Set standards of “good” and “bad” as opposed
to “right” and “wrong”
 Ethical behavior
 What is accepted as good and right in the
context of the governing moral code

51.  Law, values, and ethical behavior:
 Legal behavior is not necessarily ethical
behavior
 Personal values help determine individual
ethical behavior
Terminal values
Instrumental values

52. Alternative Views of Ethical
Behavior

53. What is code of ethics
A code of ethics is
 A systematic set of rules and procedure used to guide
the behavior of an individual, a business or a culture
 The code of ethics is in writing and available to
everyone who is expected to abide them

54. How do ethical dilemmas
complicate the workplace?
 An ethical dilemma occurs when choices, although
having potential for personal and/or organizational
benefit, may be considered unethical.
 Ethical dilemmas include:
 Discrimination
 Sexual harassment
 Conflicts of interest
 Customer confidence
 Organizational resources

55.  Ethical behavior can be rationalized by convincing
yourself that:
 Behavior is not really illegal.
 Behavior is really in everyone’s best interests.
 Nobody will ever find out.
 The organization will “protect” you

56.  Factors influencing ethical behavior include:
 The person
 Family influences, religious values, personal
standards, and personal needs.
 The organization
 Supervisory behavior, peer group norms and
behavior, and policy statements and written
rules.
 The environment
 Government laws and regulations, societal
norms and values, and competitive climate in
an industry.

57. How can high ethical
standards be maintained?
Checklist for dealing with ethical dilemmas
Step 1. Recognize the ethical dilemma
Step 2: Get the facts
Step 3. Identify your options
Step 4. Test each option: Is it legal? Is it right? Is it
beneficial?
Step 5. Decide which option to follow
Step 6. Double-check decision by asking the “spotlight”
questions: “How would I feel if my family found out
about my decision?” “How would I feel about this if my
decision were printed in the local newspaper?”
Step 7. Take action.

58. Types of Management Ethics
 Immoral
 Recognize the ethical issues involved and choose to do the
wrong thing.
 Moral
 Recognize the ethical issues involved and choose to do the
right thing.
 Amoral
 Do not consider the ethical implications of an action or
believe that ethics are irrelevant.

59. Major Sources of Ethical
Values in Business

60. The Overlap Model of Law,
Ethics and Morals
 While all three approaches of law, ethics, and morals
attempt to give us guidance as to the propriety of our
conduct, they do not always give us the same answers.

61. Definitions
 Ethics: Rules of conduct based on consensually-
accepted standards of behavior. (Conventional
Approach)
 Morals: Absolute Precepts of personal behavior based
on religion or philosophy. (Principles Approach)
 Law: Formal standards that permit or forbid certain
behaviors.

62. How Companies Manage Ethics
Seven Steps:
 Establish compliance standards and procedures
 Code of Conduct
 Ethical oversight occurs at high levels of management
 Do not delegate authority to persons who are prone to
engage in criminal behavior
 Use background checks

63.  Communicate standards to all employees
 Ethics Training Programs
 Establish Monitoring and ethical auditing systems
 Consistently enforce standards
 Immediately after an offence take steps to prevent
future offences
