COMPUTER SYSTEMS IN ORGANIZATIONS
Catalog Description: General system and information theory. Modeling organizations, activities, hardware, data, and software using current techniques with emphasis on human-computer interaction, systems engineering, and project planning. Students will study parts of actual organizations. Prerequisites: CSE 330, MATH 272, MATH 262 or consent of instructor (4 units). May not be taken by students with credit for CSE 372.
This course was taught at least 6 times as CSE372.
It is being taught for the first time as CSE557 this quarter
It is normally scheduled once per year.
no required text book.
Instead there will be readings on the Web.
I will refer you to a particular page on my web site for this class
[ http://cse.csusb.edu/dick/cs557/ ]
for you to study.
You will have to follow some of the links on these pages and study what you find there.
Most readings will have a set of review questions to be answered as the assigned work for the class.
- The course is required in the BA interdisciplinary and web options.
- This class shows you how real organizations use computers.
Your long term career
depends on how
well you understand the way organizations work
and how computers can be used in them.
- This course teaches you how to produce software
that helps an enterprise work better
by working well the other parts of the enterprise.
The software must fit the other parts or there will be trouble.
Example: My HMO/Insurance is highly computerized but
- My doctor complains that computerizing his paper work
has reduced the number of patients he sees each day from 30 to 20... and
he feels he is working harder than before.
- In another part of the organization, the pharmacy, you can order
a refill by the web or the phone, and it appears to work,
but the order does not get through to the pharmacists. Sometimes it gets through, and is fulfilled
and then lost!
- My wife had to give an annual chest xray report to the local school
district. This usually works OK
but one year the filled-in form vanished between the XRay tech, her doctor, and the reception desk
where it is picked up. It took two hours to find it.
- The HMO has got an excellent private Email system for doctor-patient-laboratory
communications. But some parts of the enterprise do not use it and rely on paper
and phone calls.
This course should help you find out why the above stories happened
and suggest feasible ways to avoid them.
- This course reviews hardware and software options
from the point of view
of both the user and the computer professional.
- Knowledge of systems analysis and design will count in winning a job.
This is course
covers a lot of systems analysis and design.
- Being able to spot risks, opportunities, and problems
is a vital skill. This course will show you how to look at a
situation and find them. It also has ways to discover improvements that reduce risks,
take advantage of opportunities, solve problems, etc.
This is a useful set of skills in any job.
- We will cover the traditional and Unified forms of diagrams.
- I will show you how to design and evaluate systems of programs.
- I will suggest methods for planning and managing projects.
- We will cover the operation, support, and maintenance of systems.
These are a vital activities in real systems.
- Field Trips!
- No Programming!
Note: many of the skills are embodied as procedures,
Data Flow Diagrams, Critical Path Method,
Entity-Relationship Diagrams, Normalization, Activity Diagrams,
etc., I expect you to learn to do them correctly.
(Required Reading): You will be required to read
handouts and designated pages on the World Wide Web.
Detailed reading assignments will be in the pages for each class on the
web -- these will be ready in time to prepare for each class.

As you study these web resources look out for
Stories, Patterns, Principles, Diagrams, Calculations, Errors,
Smells, and Jokes.
(short concrete descriptions of something of interest) are a neat way to express an idea. They
will be used to introduce topics. eXtreme Programming uses them for requirements.
"War stories" of real life systems are worth taking note of. I will also use every
day examples (making coffee, say) to illustrate techniques that are normally applied
in more realistic situations. Also see Jokes below.
are solutions to complex problems that are good enough to be used again
and again. An example might be called: "Reduce Paperwork" and another
"Keep It Simple, Stupid". Watch out for these in each topic we cover.
are general properties or rules that we use.
Some are based on theory and sometimes on practice.
Again look out for these.
are useful tools.
Typically we sketch them on paper or a board as we think about the systems.
We use tools to make tidy versions when we need to either preserve or present them.
We express our ideas about particular systems
pictures with well defined meanings. An example is the Data Flow Diagram
or DFD that shows how parts of a system effect each other. Another is the
Activity Diagram that records a particular procedure used in an organization.
You must master the rules for half-a-dozen diagrams so you can use them as
needed in your career. We use these like a mathematician uses formulas and an
engineer uses circuit diagrams (
[ http://xkcd.com/730/ ]
Joke) or engineering drawings
[ V4_AR_kit_improved.jpg ]
help check that our diagrams work.
We use calculations
to evaluate designs and plans. For example we can
use an activity diagram to describe the work to be done, and the
"Critical Path Method" to calculate how long it will take and which steps
in the plan are most critical for completing it before the time is up.
occur when you don't follow the rules for particular Diagrams or
Calculations -- like
when you add 2 and 2 and get the answer 5.
- 2 + 2 =
- These are like syntax errors
uncovered in your program by a compiler. I expect you to spot these mistakes
in quizzes. You must avoid them in your project work.
tell you something is wrong. For example
a good doctor can diagnose a strep throat from the smell on the patient's
breath. Similarly a program that does not give a name to a constant
does not smell good: it might compile and run, but something is rotten
in it. A smell in a diagram does not mean it is incorrect -- but it means
you should try figure out what is really going on, and perhaps change
the diagram. For example if a system produces and stores data that is
never used, then this smells.
encapsulate folk wisdom. Here is an example.

(History and origins)
This web site
[ http://www.jiludwig.com/ ]
seems to talk sense.
The Wikipedia is fairly trustworthy on analysis and design, but check with me.

I will be using my standard straight-line grading
scheme based on a 500 point nominal total. See

on my main web site.
40 points(8%). Lectures and discussions will be based on assigned reading.
Participating in the 20 classes will be worth 2
point each. My plan is to set you lots of exercises starting with a task to
be done while I grade the
[ Assigned Work ]
next below. There will be short lectures.
36 points(7.2%). There are 18 assignments.
Each is worth 2 points. You will normally be given some web pages to study.
They end with a set of review questions. You should try to answer as many of
review questions as you have time for. Bring one question and its answer to class
on a piece of paper with your name on it.
It is worth 2 points. If you don't have a review question+answer
hand in a blank sheet of paper with your name on it to at least
prove you were in class. In some class meetings there is no reading and so
no review questions. Instead hand in a question you want answered.
45 points(9%). There will be 3 field trips (TBA).
Two of these are "real" and one is "virtual" this quarter
Participation is worth 5 points and a written report
10 points. The report is due at the start of the
following class. It should be at least one page long. It should present
your own observations and thoughts.
You can make up for missing a field trip by organizing your own visit to any
office on campus and writing a report on how computer technology is used in
50 points(10%). Parts of five(5)
sessions (Schedule) will be dedicated to developing a team project
that interests you.
5 points will be
given for work done in class time and a further 5
points for completing the work ready for the following
session. Hand in what you have at the start of the next
session. I may also ask for a short progress report from each team
at the start of the class. At the end of the course you will be asked
to present your project to the class. These projects will be passed to
CSE375 for further development. In the past some projects have
been implemented as Senior Projects.
150 points(30%), 30 points each in 5 classes(Schedule).
Quizzes will test your memory of topics covered plus skill with
the techniques covered.
This the largest component in the assessment prior to the final.
They are the best predictor of your score in the final and so the
course. But you can improve your skills and knowledge before the final
by reviewing the graded quizzes.
You can earn the standard 5 points bonus/make up points by attending
a computer science seminar or Masters project presentation.
[ ../seminar/ ]
for the schedule. You must attend the seminar and,
at the next class meeting, email me a short report: who, what, when, why, how, ...
(less than 250 words) on the presentation within 24 hours of it finishing.
You can make up 5 points lost
before the final. They have no effect on your score in the final.
You can score a maximum of 300 points in bonuses and course work.
200 points comprehensive(40%). Questions will
be based on work done in the course
(including reading, exercises, quizzes, field trips, and project work)
during the quarter.
This final examination needs special preparation -- go back over everything we have done to prepare for it.
