4. Towards Software Engineering
Profession
What does it like?
1. Body of Knowledge (e.g. SWEBOK)
2. Standards
3. Best practices (i.e. techniques proven to
work)
4. Education
5. Code of Ethics
6. Certification mechanism
7. Licensing mechanism
5. Definition
Standard:
Mandatory requirements employed and
enforced to prescribe a disciplined uniform
approach to software development, that is,
mandatory conventions and practices are
in fact standards.
(ISO/IEC 24765, Systems and Software Engineering Vocabulary)
8. Software engineering
standard
Approximately 315 software engineering
standards,
guides, handbooks, and technical reports
are maintained by approximately 46
professional, sector, national, and
international standards organizations.
9. Roles of Software Engineering
Standards
1. Specify techniques to develop software
faster, cheaper ,better, IEEE 982.1
(Measures for Reliable SW)
2. Provide consensus validity for “best
practices” that cannot be scientifically
validated, IEEE 1008 (Unit Testing)
3. Provide a systematic treatment of
“-ilities”, IEEE 730 (SW Quality Assurance)
10. Roles of Software Engineering
Standards (cont‟)
4. Provide uniformity in cases where
agreement is more important than small
improvements, IEEE P1320.1 (IDEF0)
5. Provide a framework for communication
between buyer and seller, IEEE/EIA 12207
(SW Life Cycle Processes)
6. Give precise names to concepts that
are fuzzy, complex, detailed and
multidimensional, IEEE 1028 (SW Reviews)

17. Why Use Standards?
1. Establish uniform requirements and
vocabulary for development and
documentation.
2. Define a common framework for
software life cycle processes.
3. Clarify the roles and interfaces of
participants.
4. Clarify the types and contents of
documentation.
18. Why Use Standards? (cont‟)
5. Identify the tasks, phases, baselines,
reviews, and documents needed.
6. Follow the lessons learned and proven
(best) practices of the industry
7. Avoid the pitfalls and problems of the
past.
8. Save time and $ by not reinventing the
wheel again.
19. Why Use Standards?
9. Select a supplier or a developer (e.g. ISO
9000)
10. Impose requirements in a contract.
11. Impose a trade barrier.

21. Sources of Standards
1. Within an organization
Documented from day-to-day activities
2. From consultants mandated to develop
them.
3. From manufacturers‟ user groups (e.g.
IBM)
4. From a group of companies working
together.
22. Sources of Standards (cont‟)
5. From professional groups (e.g. IEEE)
6. From government agencies (e.g. NASA,
Transport)
7. From Standards Organizations (e.g. ISO)
8. From Countries (e.g. Conseil
canadiendes normes)
23. Software Engineering
Standards: Importance
1. They consolidate existing technology
into a firm basis for introducing newer
technology.
2. They increase professional discipline
3. They protect the business
4. They protect the buyer
5. They improve the product
