The Deming Cycle — Everyone Should Know It.

December 13, 2017

The Deming Cycle, the historical basis for all Quality
Assurance Programs, helped Japan to recover after World
War II.

The Deming Cycle consists of four steps: Plan, Do, Check
the Results, and Alter the Plan if necessary.

The Deming Cycle is a good definition of common sense.
I have used it on many occasions without knowing it.

When applying the Deming Cycle, when do we learn new and
better ways of doing our task?

We learn during the fourth step of the Deming Cycle when
we Alter our Plan.

WHATIFWE were all taught the Deming Cycle as a part of
our public education?

The Computer Wisdom of Bugs Bunny

December 6, 2017

Do you remember the Bug’s Bunny cartoon where he pops out of the ground
in the middle of the desert and says “I think that I should have turned
left at Albuquerque”?

Mistakes always happen; some because of stupidity, some because of greed;
some because the required knowledge was not available, and some because
we are just human beings.

We are currently experiencing a great many security problems due to
hackers.

The basic computer design that makes this possible has a common program
and data buss. Hackers can cause their program to be loaded on the target
machine via this common buss.

In the late 1970’s, there was a different computer design, the Harvard
Architecture with separate data and program busses. This architecture
cannot be hacked.

About 1985, the microprocessor became practical and the Harvard
Architecture became obsolete.

“Did we turn right at Albuquerque in error”? I believe so. Could
have avoided it? I think not. We could not have predict the future.

Should we re-vitalize the Harvard Architecture? I think the benefits
would greatly out-weigh the costs.

The Most Important People In Our Society.

November 22, 2017

Who are the most important people in civilized society?

Are wealthy individuals the most important people in our
society? No, they are not.

Are celebrities the most important people in our society?
No, they are not.

Do religious organizations contain the most important
people in our society? No, they do not.

Are government officials the most important people in our
society? No, they are not.

The artisans and highly skilled professionals are the most
important people in any civilized society.

Nothing of any value gets done without the participation
of these highly skilled professional.

WHATIFWE increased the number of highly skilled home-based
pioneering professional software engineers?

Software Engineers are Quality Assurance Managers

November 14, 2017

Have you ever noticed that Quality Assurance, ISO-9001,
and the Deming Cycle is taught only in Business Administration?

I have found that when Quality Assurance was taught in Engineering
Schools, it was in Engineering Management Classes.

Is Quality Assurance just an Engineering Management Problem? Is
a Software Engineer a Quality Assurance Manager?

Computer Programs are special Deming Plans to be Done at the
client’s site by a computer not by a human being.

Software Engineers are, in reality, Quality Assurance Managers.
For the most part, they do not realize this fact.

WHATIFWE taught Quality Assurance, ISO-9001, and the Deming
Cycle to all Engineers in our Engineering Schools?

Software “Breaks”!

November 1, 2017

A 17 year old sailor on a submarine must be able to
fix a critical piece of electronic equipment within
15 minutes.

Critical submarine hardware has the required subsystems
to facilitate the location of a failed replaceable components.

Most hardware these days has at least one computer within it.
This includes critical submarine systems.

Can the same 17 year old sailor on a submarine find and
correct a critical software failure within 15 minutes?

Does software “break”? Not really. but software fails when
it illegally or incorrectly writes some data.

Programmers have many ways of preventing illegal writes which
they use in checkout and then remove before delivery.

WHATIFWE used formal illegal write prevention code in delivered
software?

Resume Preparation: A Gigantic “Plumbing” Project

October 25, 2017

We all understand a Plumbing Project. This where a supposedly
simple task become a massive, complex effort.

One of the common “Plumbing Projects” in today’s environment
is the preparation of a resume.

Each resume must be customized to the target audience. This
effort usually takes several hours to complete.

Resumes are always needed: Job searches, contracts, professional
network, and volunteering activities.

The resume effort is made more complex due to the need to paste
it into a web-site window, discovered usually at the last moment.

I have been using my Programmable Software Development Environment
to maintain its manual. Its use has greatly simplified this task.

WHATIFWE used the Programmable Software Development Environment
to develop resumes? Would it help? Yes it does!

I, A Programmer, Am Also A Quality Assurance Manager

October 18, 2017

To be strictly compliant with ISO-9001, Programmers must
use enforceable standard methods and processes.

Assembly Language Programmers used macros for common
multi-instruction processes. These macros, once developed,
were never changed.

Software “breaks fatally” when it illegally writes. The
error cannot be fixed and it might take the machine down.

There are many error detection code segments that programmers
use during checkout and then remove before delivery.

I developed a C++ Macro Preprocessor to provide a highly
competent macro capability to facilitate using error detection code.

Unlike the Macro Assembler, my C++ Macro Preprocessor prepared
source code exclusively from the Macros.

IBM developed the first piece of error-free software in 1968.
It was the PL/1 Compiler and it was a joy to use.

The PL/I Compiler was error free due the strict application of
the requirements of simple precedence.

In the late 1960’s, Bob Prince of Lockheed developed a simple
precedence based compiler writer which I used.

In the early 1970’s, I used the Lockheed Compiler Writer to
prepare non-compiler applications with moderate success.

I had difficulty with the Compiler Writer on non-compiler
applications because data flows differently than processes.

I realized many years later that a multidimensional precedence
process could manage both processes and the data flow.

I learned how to make a set of coupled precedence processors
that “policed” the use of classes and the flow of data.

I updated my C++ Macro Processor to render it capable of
deploying simple precedence principles to my programming efforts.

My Macro Processor satisfied the Standard Methods and
processes requirements of ISO-9001.

I inadvertently became a Quality Assurance Manager.

Prague Conference in 1987

October 11, 2017

In 1987, I presented a scientific paper at a conference
in Prague, Czechoslovakia.

At that time, Prague was a city in the territory under
control of the Soviet Union.

I have always performed my research on my own time and money.

I attended the conference on my vacation.

Needless to say, the other attendees were quite curious
about my personal research efforts.

During this time, I had an interesting conversation with
a Polish attendee while walking along the river:

POLISH ATTENDEE: We are not special.

MY RESPONSE: Being special is defined by what you do
to be the very best in your field.

POLISH ATTENDEE: We have no resources.

MY RESPONSE: Do you have a personal computer at your home?

POLISH ATTENDEE: Yes.

MY RESPONSE: Probably a better one than I have. My is
a Heathkit H89.

POLISH ATTENDEE: The bosses will not like it.

MY RESPONSE: Usually, the bosses don’t kill the goose
that lays the golden egg right away.

At this point he understood and I was effectively
“walking on water”.

You ask: why am I sharing this little bit of history
with you.

History is a great teacher and today we need to learn
this lesson.

Monte-Carlo Test Method

October 4, 2017

A Number of years ago, I had a contract to build a hardware
control sub-system software product.

This hardware control sub-system was designed to control
legacy hardware shipped back from the Middle East.

This legacy hardware appeared to have not been well-maintained;
it needed a lot of service.

I was afraid that I might break this hardware when I tested my
hardware control sub-system software product.

I developed a Monte-Carlo Simulator/Stimulator Test System to
validate my hardware control sub-system product.

The Monte-Carlo technology is based on a pseudo-random generator.
It was originally used in the development of nuclear weapons.

The random nature of my Monte-Carlo Test System enabled me to
rapidly and thoroughly test the hardware control sub-system, both
from a user and hardware point-of-view.

The use of a Monte-Carlo Simulator/Stimulator Test System
enabled me to deliver an error-free software product.

WHATIFWE used Monte-Carlo software test methods for all software.
Would we get better products?
