Industry’s Persistent Challenges
•
•
•
•
•
•
Projects of increasing complexity
Rapidly changing requirements
Pressures for faster time to market
Need to re-design major systems
Integration of new processes and techniques
Talent shortage: needed software
engineering skills often in short supply

Industrial Companies are Good at
• Focusing on “right now” issues
–
–
–
–
Responding to market pressures
Responding to competitive threats
Developing “bottom-line” solutions
Applying technology to immediate problems
• …Expedience

Undesirable Facts of Life
•
•
•
•
Organizations “go with what has worked in the past”
“Out of date” practices become institutionalized
Few people know, or can integrate, best practices
Everyone is too busy getting product out the door to
spend time in education or training or addressing
these problems effectively

Security Industry Automation
Corporation
• Build/Operate NYSE/AMEX trading systems
• High volume, transaction processing systems
that demand the highest levels of reliability.
• Financial markets depend on these systems
• SIAC must provide reliability assurances
• Innovation and cleverness are not sufficient

SIAC Education Program
• Tuition assistance for college courses and degrees
• Leadership and management development
• “Technical” training
BUT
• Process & Engineering “under-appreciated”
• Few good local software engineering programs
• Hard to find the time to actually take training
2/26/2002

Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Universities are Good at ...
• Keeping up with the latest developments
• Organizing knowledge into a structure that
facilitates understanding and learning
• Advancing knowledge
• Taking the time to solve problems that
industry is too busy to address
2/26/2002

Persistent Challenges for
Universities
• Maintain comprehensiveness and structural
integrity of academic programs in rapidly
changing fields
• Maintaining a connection to real, industrial
problems
• Getting too focused in narrow domains due to
opportunistic funding opportunities
• Shortage of faculty talent: software “engineering”
skills in particularly short supply
2/26/2002
11
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
SMU MS Program in Software
Engineering
• Started in 1993, based on
– SEI masters level model curriculum
– SEI CMM
– Local industry needs -- and pressure for something
beyond computer science
• Comprehensive program with a dozen
software engineering courses
• Most faculty have industrial experience
• Strong distance education options
2/26/2002
12
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Challenges for the SMU Program
• Keeping up to date with rapid
improvements in the field
• Keeping ties with industrial needs
– Adjunct faculty and outreach programs
– Distance education
– Learn from students
• Supporting innovative delivery formats
(distance education, etc.)
2/26/2002
13
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
NTU Program
• National Technological University
broadcasts course from about 3 dozen
universities over satellite to hundreds of
industrial companies
• Software engineering program started about
1995, based on SEI model curriculum
• Same challenges as SMU, plus
– keep up with distance education technologies
– form a cogent program out of many universities

How SWEBOK Was Used

15
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
The Need for a Model
• Industry needs a model of software engineering to
relate knowledge with business needs and career
growth options
• Academia needs a model of software engineering
to help avoid gaps in program coverage and help
assure structural integrity to academic programs
• The model must develop, adapt and grow with the
field

• Opportunity to plan expeditiously
• Intuitive acceptance of the structure
• Individual and organization planning were supported
• Education and SPI initiatives were in alignment
2/26/2002
18
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Things that were Learned - SIAC
• Organizations seek to act expeditiously
• Even very busy organizations will embrace
opportunities where they perceive an alignment
with their needs, and a timely return on their
investment
• The SWEBOK supported a straightforward
characterization of what & where education was
needed, allowing:
– Expeditious choices to be made
– Quicker returns expected

• The courses and detailed topics were mapped to the
detailed structure of the SWEBOK
• The structure was pretty natural and the mapping was
straightforward
2/26/2002
20
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Things that were Learned - SMU
• “Holes” and overlaps in course coverage
– For example, a course on software tools was
clearly needed
• Need to update course content in selected
areas
• A clear way to provide an overall
framework from which to describe the
program to potential students
2/26/2002
21
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Using SWEBOK to Examine the
NTU Software Engineering Program
• The problem here was that courses come from many
universities, and there needs to be a model by which
to correlate their content and determine equivalencies,
overlaps, etc.

Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Things that were Learned - NTU
• The SWEBOK categories made an excellent
system for categorizing courses
– And will be used for course numbering in the
future
• Holes and overlaps in course coverage were
considerably more apparent
• The SWEBOK provides a “neutral” basis
for discussion when universities disagree
about what should be covered
2/26/2002
23
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Things that were Learned about
SWEBOK
• Seems overly dependent on standards
– Those outside the standards community do not see it
the same way as those inside
– Little guidance about relevance or applicability of
standards to specific kinds of software (example: IEEE
Standard 829 for software test documentation)
– Some standards obscure the actual content (example:
top layers of management topic are based on 12207
categories rather than things people recognize as key
topics in software management)
2/26/2002
24
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Things that were Learned about
SWEBOK (continued)
• Structure reminds people of “waterfall”
– Some feel it doesn’t fit newer lifecycle models
• Unequal size of knowledge areas
– Design is clearly much richer than configuration
management, for example
• Lingering concerns due to opposition from several
communities
– Mostly due to political issues and the relative
immaturity of the field

Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
New NTU Program Structure
• Each major course category (one digit in
course number) will be associated with one
or two KAs from SWEBOK
• Course content will be mapped to
SWEBOK at a more detailed level, to
determine equivalencies and overlaps

Outlook
2/26/2002
34
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
SIAC and Other Companies
• Interest continues
• Making very positive and tangible
improvements that cause management to
continue support despite financial
constraints
2/26/2002
35
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
SMU and NTU
• Further refinements and program structuring
are anticipated
• The structure is helping both universities
“sell” their programs to new customers
2/26/2002
36
Using SWEBOK ...Copyright © James Mason and Dennis J. Frailey, 2002
Need for Update and Revision of
SWEBOK
• All of these uses of SWEBOK are
predicated on the assumption that it will
keep up with the times
• We also need a clear mechanism for
providing feedback to SWEBOK authors
