**CS 190 Computer Science Design Project**

This section has as its main theme that *working* in information
technology usually involves many people. The point is that instead of exercising
one's special skills, significant accomplishment requires people to cooperate,
*synthesize their individual products to make up a joint
effort*, or, at minimum, convince another that something of
substance has been done.

By week six a project team should have completed some work toward its ultimate goal. Since the project has been described (we'd hope that was done by third or fourth week), there is a draft of an abstract, summary. That kind of item is a short paragraph. Building of an overview of the project is the next job.

An outline is an overview document. It is analogous to a table of contents in a finished document (e.g., a report or book). One way to report about a project is to create a talk outline that goes over the entire effort.

Another overview approach expands the description and adds to it a
work plan. That approach is used in the
Pyramid project.
[Item I. there was edited by A. Klinger. Questions in parentheses there
are suggestions for improvement by B. Darrah, who is doing this as a
Master's Comprehensive project.]

Creativity takes many forms. The range is from
a novel concept to a complete invention described by a working prototype
that resolves a need. At origination, work could consist of *a description*
of new software, hardware, analysis, or system activity.

*Cooperate*

*Communicate*

Email led to a search engine result. Here is the complete exchange.

*Cooperation* flowed out of the email communication; *work* is shown by the *new result * (title, year).

*Tabulated Computations *

*(The following is to enable constructing better html, which will be done
over time.)*

The following also involved email, and some computational work. The
entire task initiation (through creation of a first draft of the table)
took only hours although it required cooperation. Calculations on data
in email responses from a majority of the students completed within a
short time period from the initial inquiry form the basis of this work.
A partial summary was sent out "Date: Thu, 19 Feb 1998 22:38:30 PST" with the header "Subject: Results" and text excerpts:

As an experiment I tested the numbers provided by ... people
who've responded to my msgs today about birth-date/social-security-no.
Using Mathematica I determined the integer factorizations of those
numbers, and my own values, leading to items I've entered into a file that
represents my effort to "write it down" or "keep an engineering
notebook" record. Then I created the first draft of a table that
summarized the key data. Here's that table. ...

*The email table draft covered much of the following (which has been
revised to include a new datum and clarification of title/headings):*

That utility was used to determine the following facts, comparing

experiment (see Table W.2).
