Software Engineering Code of Ethics and Professional
Practice
"The time is right to get serious about this. As software
becomesincreasingly dominant in the IT industry, and, indeed,
in everything else, there is an obvious need for a
professional-level recognition. Far too much is placed on
particular credentials for specific products or applications
without regard to the bigger picture. The result is poorly
engineered software projects."
(Version 5.2) as recommended by the IEEE-CS/ACM
Joint Task Force on Software Engineering Ethics and
Professional Practices and Jointly approved by the ACM and
the IEEE-CS as the standard for teaching and practicing
software engineering.
Short Version
Preamble
The short version of the code summarizes aspirations at a
high level of the abstraction; the clauses that are included
in the full version give examples and details of how these
aspirations change the way we act as software engineering
professionals. Without the aspirations, the details can
become legalistic and tedious; without the details, the
aspirations can become high sounding but empty; together, the
aspirations and the details form a cohesive code.
Software engineers shall commit themselves to making the
analysis, specification, design, development, testing and
maintenance of software a beneficial and respected
profession. In accordance with their commitment to the
health, safety and welfare of the public, software engineers
shall adhere to the following Eight Principles:
- 1. PUBLIC
- Software engineers shall act consistently with the
public interest.
- 2. CLIENT AND EMPLOYER
- Software engineers shall act in a manner that is in the
best interests of their client and employer consistent with
the public interest.
- 3. PRODUCT
- Software engineers shall ensure that their products and
related modifications meet the highest professional
standards possible.
- 4. JUDGMENT
- Software engineers shall maintain integrity and
independence in their professional judgment.
- 5. MANAGEMENT
- Software engineering managers and leaders shall
subscribe to and promote an ethical approach to the
management of software development and maintenance.
- 6. PROFESSION
- Software engineers shall advance the integrity and
reputation of the profession consistent with the public
interest.

learning regarding the practice of their profession and
shall promote an ethical approach to the practice of the
profession.
Software Engineering Code of Ethics and Professional
Practice
IEEE-CS/ACM Joint Task Force on
Software Engineering Ethics and Professional
Practices
Full Version
Preamble
Computers have a central and growing role in commerce,
industry, government, medicine, education, entertainment and
society at large. Software engineers are those who contribute
by direct participation or by teaching, to the analysis,
specification, design, development, certification,
maintenance and testing of software systems. Because of their
roles in developing software systems, software engineers have
significant opportunities to do good or cause harm, to enable
others to do good or cause harm, or to influence others to do
good or cause harm. To ensure, as much as possible, that
their efforts will be used for good, software engineers must
commit themselves to making software engineering a beneficial
and respected profession. In accordance with that commitment,
software engineers shall adhere to the following Code of
Ethics and Professional Practice.
The Code contains eight Principles related to the behavior
of and decisions made by professional software engineers,
including practitioners, educators, managers, supervisors and
policy makers, as well as trainees and students of the
profession. The Principles identify the ethically responsible
relationships in which individuals, groups, and organizations
participate and the primary obligations within these
relationships. The Clauses of each Principle are
illustrations of some of the obligations included in these
relationships. These obligations are founded in the software
engineer's humanity, in special care owed to people affected
by the work of software engineers, and the unique elements of
the practice of software engineering. The Code prescribes
these as obligations of anyone claiming to be or aspiring to
be a software engineer.
It is not intended that the individual parts of the Code
be used in isolation to justify errors of omission or
commission. The list of Principles and Clauses is not
exhaustive. The Clauses should not be read as separating the
acceptable from the unacceptable in professional conduct in
all practical situations. The Code is not a simple ethical
algorithm that generates ethical decisions. In some
situations standards may be in tension with each other or
with standards from other sources. These situations require
the software engineer to use ethical judgment to act in a
manner which is most consistent with the spirit of the Code
of Ethics and Professional Practice, given the
circumstances.
Ethical tensions can best be addressed by thoughtful
consideration of fundamental principles, rather than blind
reliance on detailed regulations. These Principles should
influence software engineers to consider broadly who is
affected by their work; to examine if they and their
colleagues are treating other human beings with due respect;
to consider how the public, if reasonably well informed,
would view their decisions; to analyze how the least
empowered will be affected by their decisions; and to
consider whether their acts would be judged worthy of the
ideal professional working as a software engineer. In all
these judgments concern for the health, safety and welfare of
the public is primary; that is, the "Public Interest" is
central to this Code.
The dynamic and demanding context of software engineering
requires a code that is adaptable and relevant to new
situations as they occur. However, even in this generality,
the Code provides support for software engineers and managers
of software engineers who need to take positive action in a
specific case by documenting the ethical stance of the
profession. The Code provides an ethical foundation to which
individuals within teams and the team as a whole can appeal.
The Code helps to define those actions that are ethically
improper to request of a software engineer or teams of
software engineers.
The Code is not simply for adjudicating the nature of
questionable acts; it also has an important educational
function. As this Code expresses the consensus of the
profession on ethical issues, it is a means to educate both
the public and aspiring professionals about the ethical
obligations of all software engineers.
Principles
Principle 1 PUBLIC
Software engineers shall act consistently with the public
interest. In particular, software engineers shall, as
appropriate:
- 1.01. Accept full responsibility for their own
work.
- 1.02. Moderate the interests of the software engineer,
the employer, the client and the users with the public
good.
- 1.03. Approve software only if they have a well-founded
belief that it is safe, meets specifications, passes
appropriate tests, and does not diminish quality of life,
diminish privacy or harm the environment. The ultimate
effect of the work should be to the public good.
- 1.04. Disclose to appropriate persons or authorities
any actual or potential danger to the user, the public, or
the environment, that they reasonably believe to be
associated with software or related documents.
- 1.05. Cooperate in efforts to address matters of grave
public concern caused by software, its installation,
maintenance, support or documentation.
- 1.06. Be fair and avoid deception in all statements,
particularly public ones, concerning software or related
documents, methods and tools.
- 1.07. Consider issues of physical disabilities,
allocation of resources, economic disadvantage and other
factors that can diminish access to the benefits of
software.
- 1.08. Be encouraged to volunteer professional skills to
good causes and contribute to public education concerning
the discipline.

competence, call upon the opinions of other professionals
who have competence in that area.
