[misc.jobs.misc] Practical Experience

It has long puzzled me why there are so few masters degree programs in
Software Engineering and even fewer (none that I know of) bachelors
programs.  Consider what universities offer our engineering brethren:
Students interested in research study, for example, chemistry, math,
or physics; those interested in building products get a degree in,
e.g., chemical engineering, electrical engineering, or civil engineering.
Of course, the engineering students must learn a foundation in the
underlying sciences, but they also learn how to apply science to
real commercial problems.

In the world of software, there would seem to be similar educational
needs:  Computer science for those exploring frontiers of the software
art, and software engineering for (the much greater number of) people
who are building software products.

Exposure to the hardware side of computing is but *one* aspect of what
distinguishes a software engineering education from a computer science
education.  In illustration of some other aspects, I'll mention a few
of the features of the Masters of Software Engineering program that I
recently completed (at the now-defunct Wang Institute of Graduate Studies):

--Two years of work experience with software was required for admission;
  students fresh out of a B.S. program were not accepted.

--Thorough grounding in computer science fundamentals (e.g, discrete
  math and data structures) was required.  As one who got his B.S. in
  the Old Days, I found meeting the admissions requirements almost as
  valuable as the degree program itself.  Then the first course in
  the program was APPLICATION (emphasis mine) of Formal Methods, such
  as classifying real problems according to complexity theory.

--Group work on projects was required.  In particular, instead of an
  individual thesis (which was not an option), one had to develop
  and deliver two software products with teams of fellow students.

--Exposure to non-technical aspects of software development was an
  essential part of the degree.  For example, a course in software
  project management was required, not to mention the lessons learned
  in the group projects.

--There was a heavy emphasis on techniques (e.g., structured analysis
  vs. Jackson's methods) and tools (from spreadsheets to compiler
  generators).

Hey, it's tough being a cheerleader for an alma mater that no longer exists!
But there are other programs with a similar slant (such as at the various
institutions where the former Wang Institute faculty have landed).  And
enterprising students can bend traditional computer science programs in
this direction.  Use your electives to take the courses required of
"real" engineers (Electric Circuits, Thermodynamics, Statics, ...).
Work as a programmer summers or between degrees or in a co-op program.
Develop a program useful to others (including the users manual!) as part
of your thesis.

There is a good case to be made that Software Engineering is not an
appropriate baccalaureate field of study and that the professional
M.S. as you described Wang Institute's M.S.E (R.I.P.) is the only
reasonable way to go.  Wang's entrance requirements helped to ensure
that the MSE was not just an advanced hacker's degree. (yech, what a
concept.)

There is, in fact, a strong case that can be made to the effect that
software is OVERemphasized in current B.S. CS programs at the expense
of problem-solving, analytical skills, mathematics, and CS theory.
The question to ask is, "How much of our undergrad program will be
obsolete in 10 years?" Too many places must answer with too high a
figure.  Students are better served in the long run by not getting a
CS(E) undergrad degree - especially the narrow, inflexible,
hacker-driven mush being pushed by the accrediting agencies.

See this month's CACM for yet another attempt at defining what a 
CS curriculum is.  Since the underlying science is so ill-defined,
the engineering discipline sits atop sand.  It is appropriate for
intensive study only by those who really need it immediately -
people working in the field who, one hopes, have outgrown their
hacker phase and are ready to adopt the mantle of professionals.
In other words, Software Engineering remains most appropriate for
a professional M.S. program.

In this case I was referring to a systems software engineering; i.e.
one who is applying the skills and techniques of software engineering
to a hardware related application.  Granted Steve, it *is* an
application, but one that all computer scientists should be versed in;
otherwise they would just be programmers. :-)

The original point of discussion which started all this was: "Who is
better qualified to develop software that requires moderate to
in-depth level of hardware knowledge and software engineering, a BSCS
or BSEE?"

The second point I would like to quibble about is that a "software
engineering education" is something that all computer scientists
should have been exposed. IMHO, software engineering is not a separate
discipline, but it may be an area of specialty for a phd dissertation.

Exactly where is the "field" of software engineering? is it in Boise? :-)

Many industrial locations call any body which authors programs a
software engineer. While in many instances this may be true, I do not
believe that it is completely accurate.  A BSCS (CIS?) may graduate
without ever having had a single course in software engineering and
yet industry still refers to them as software engineers.

see?

Bill then goes on to make an incorrect statement:
>   It DOES cover: [...]
>   Modern Programming Language Features (Ada) ...

This is incorrect because Software Engineering is independent of, and
in no way related to a *particular* language, its features, or its
associated environment. While it is true that some languages lend
themselves to software engineering techniques better than other
languages do, software engineering and ADA are mutually exclusive.

Quoting from _Software Engineering: A Practitioner's Approach_ by
Roger S. Pressman; McGraw-Hill, 1982.:

	Software engineering "... techniques deal with software as an
	engineered product that requires planning, analysis, design,
	implementation, testing, and maintenance." 

To sum this up, Software Engineers are people who apply software
engineering techniques to their programming tasks.
