The Twitter Seminar On The Development Of Error Free Software Concludes — Session 8

PROGRAMMERS ARE SPECIAL QUALITY ASSURANCE MANAGERS!

Requiring our programmers to be special Quality Managers? This would be a terrible inconvenience?

On one of my contracts, I had the opportunity to witness an attempt to become ISO-9001 certified.

There were two ISO-9001 certification meetings; the first with the software manager and the second with QA.

The software manager had no idea as to what his group could do to be compliant with ISO-9001.

The QA manager described the increased formality required to be compliant with ISO-9001.

The body language of my client’s employees told me that no one except management wanted ISO-9001 certification.

One of the requirements of ISO-9001 is the use of “Standard Processes and Methods”.

The use of “Standard Processes and Methods” means that management would control our programming efforts.

Would you believe it I told you that programmers are already using “Standard Processes and Methods”?

No I don’t! As long as I do my job, management leaves me alone. They create more problems than they solve.

Then would you believe it I told you that programmers create their own “Standard Processes and Methods”.

No? How many times have you prepared a new source file by modifying an old previously developed source file?

Your collection of sources files defines your “Standard Methods and Processes” that you use.

Will this help you to develop error-free software? Reflect on your experience. It already has.

WHATIFWE were to make a conscious Quality Assurance Effort? Will it help? Try it, sees what happens.

My Response to Large Quantity of Comments

September 27, 2019

I am the only one managing the blog and hence
have a limited amount of time to do so.

If there are less than 100 comments, I will examine
each comment to determine whether I will approve it
or delete it.

If there are more than 100 comments, I will examine
and approve comments according the following rules:

For each group of twenty comments, I will:
1. Find the first one that I can approve.
2. Approve the selected comment.
3. Delete the remaining 19 comments.

Thank You for your understanding.

I, A Programmer, Am Also A Quality Assurance Manager

September 24, 2019

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.

ARE PROGRAMMERS SPECIAL QUALITY ASSURANCE MANAGERS?

Can a software engineer be a Quality Assurance Manager?
Quality Assurance is a management task.

To find out, let us look at the beginning of all Quality
Assurance programs; i.e., the Deming Cycle.

The Deming Cycle, first used in Japan in 1947, consists of
the following four steps.

The first Deming Cycle Step is “make a plan”. The second
Deming Cycle Step is “do the plan”.

The third Deming Cycle Step is “check the results”. The
four Deming Cycle Step is “change the plan if needed”.

The Deming Cycle appears to be a concise definition of
common sense!

Would you believe it if I told you that all programmers
are Quality Assurance Managers?

No! Then would you believe it if I told you that a computer
program is a Deming Plan?

A computer program is a Deming Plan to be done at the
client’s site by a computer, not by a person.

Most Programmers do not understand that they are very special
Quality Assurance Managers.

WHATIFWE required our programmers to be special Quality
Managers? Would this be a terrible inconvenience?

WhatifWe127 Blog — Web Browser Inquiries

September 22, 2019

There have been many comments and inquiries relative to Web
Browser and Display format problems relative to my blog and
website. I appreciate your comments but I do not have sufficient
time to individually respond to them. I have prepared this
post that will hopefully provide some answers.

Relative to the blog, I use the free Word Press blog site.
The only thing that I prepare is the text. I don’t have any
videos. I do attach pdf files containing my articles. I must
assume that WordPress is up-to-date relative to the various
Web Browsers and Displays. I have absolutely no control over
the format.

Relative to my website, I designed it a number of years ago
using Microsoft Front Page which is now obsolete. I would
assume that it would not behave properly on some of the newer
Web Browsers and Displays. I am currently redesigning it
using the CSS technology. I am using this need as a means of
building standard Web Site development kits and I cannot
at this time predict when this will be completed.

My Invitation To You

September 20, 2019

I became a software engineer in 1966 due to an experiment
that I had performed. I have never taken a course in
Software Engineering. Over the years, I have continued
to experiment on my own time and have greatly benefited
from this activity

In 1992, I became a home based software development business.
I developed a set of tools to aid me in my business activities.
These tools evolved over time and are now capable of helping
a software engineer to become a better, more competitive programmer.

I invite you to take a similar path. My tools can be downloaded
free-of-charge from my web-site, http://www.whatifwe.com and they are
well documented.

“Class Preparation” Libraries

Both the ARITHMETIC and CONDITIONAL LIBRARIES have
the needed for parameters which are either previously
defined elements or numbers.  The same software parts
are used in both cases. It is time to develop a
Parameter Library to handle this requirement.  Its
developmnent will now be started.

Prague Conference in 1987

September 17, 2019

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.

CAN WE PREVENT ERRORS DURING SOFTWARE DEVELOPMENT?

Suppose we had a software tool that produced source code
exclusively from a set of macros? Would it be restrictive?

A computing language is often considered the pallet where
the programmer expressive his creative juices.

Restricting the programming effort to a minimal set of macros
would take all of the fun out of the project.

In addition, a highly skilled programmer can be trusted to do
the job correctly without these constraints.

Would you believe it I told you that all programmers, even the
great ones, make errors.

The errors made by the junior programmers show up quickly
during checkout and are easy to fix.

The errors made by the senior programmer take a long time to
show up and are difficult to fix.

Restricting the “field of play” can greatly simplify the
development process.

Restricting the “field of play” can greatly reduce the
occurrence of errors.

In the hardware world circa 1980’s, management select the
Integrated Circuits to be used in the project.

Unfortunately, management cannot provided the an appropriate
set of software parts.

Programmers are needed to develop an appropriate set of software
parts. Is a programmer a QA manager?

WHATIFWE had a senior programmer who was also a Quality Manager?
Would this help?

The Purpose of My Blog

September 14, 2019

The original purpose of my blog was to provide me an easy
means of reporting my activity on my personally funded
research and development activities on error-free software
development methods.

I subsequently expanded the purpose of my blog to encourage
others to improve their skills by conducting their own
regular experimental process.

I became a software engineer in 1966 due to an experiment
that I had performed. I have never taken a course in
Software Engineering. You are encouraged to take a similar
path. If my tools can be of any benefit, they can be
downloaded free-of-charge from my web-site, http://www.whatifwe.com
