INTRODUCTION
The Goal is about science and education. I believe that these
two words have been abused to the extent that their original
meanings have been lost in a fog of too much respect and mys-
tery. Science for me, and for the vast majority of respectable sci-
entists, is not about the secrets of nature or even about truths.
Science is simply the method we use to try and postulate a mini-
mum set of assumptions that can explain, through a straightfor-
ward logical derivation, the existence of many phenomena of na-
ture.
The Law of Conservation of Energy of physics is not truth. It
is just an assumption that is valid in explaining a tremendous
amount of natural phenomena. Such an assumption can never be
proven since even an infinite number of phenomena that can be
explained by it does not prove its universal application. On the
other hand, it can be disproved by just a single phenomenon that
cannot be explained by the assumption. This disproving does not
detract from the validity of the assumption. It just highlights the
need or even the existence of another assumption that is more
valid. This is the case with the assumption of the conservation of
energy which was replaced by Einstein's more global-more valid
-postulation of the conservation of energy and mass. Einstein's
assumption is not true to the same extent that the previous one
was not "true".
Somehow we have restricted the connotation of science to a
very selective, limited assemblage of natural phenomena. We re-
fer to science when we deal with physics, chemistry or biology.
We should also realize that there are many more phenomena of
nature that do not fall into these categories, for instance those
phenomena we see in organizations, particularly those in indus-
trial organizations. If these phenomena are not phenomena of
nature, what are they? Do we want to place what we see in organi-
zations to the arena of fiction rather than into reality?

This book is an attempt to show that we can postulate a very
small number of assumptions and utilize them to explain a very
large spectrum of industrial phenomena. You the reader can
judge whether or not the logic of the book's derivation from its
assumptions to the phenomena we see daily in our plants is so
flawless that you call it common sense. Incidentally, common
sense is not so common and is the highest praise we give to a
chain of logical conclusions. If you do, you basically have taken
science from the ivory tower of academia and put it where it
belongs, within the reach of every one of us and made it applica-
ble to what we see around us.
What I have attempted to show with this book is that no
exceptional brain power is needed to construct a new science or
to expand on an existing one. What is needed is just the courage
to face inconsistencies and to avoid running away from them just
because "that's the way it was always done". I dared to interweave into the book a family life struggle, which I assume is quite familiar to any manager who is to some extent obsessed with his work.
This was not done just to make the book more popular, but to
highlight the fact that we tend to disqualify many phenomena of
nature as irrelevent as far as science is concerned.
I have also attempted to show in the book the meaning of
education. I sincerely believe that the only way we can learn is
through our deductive process. Presenting us with final conclu-
sions is not a way that we learn. At best it is a way that we are
trained. That's why I tried to deliver the message contained in
the book in the Socratic way. Jonah, in spite of his knowledge of
the solutions, provoked Alex to derive them by supplying the
question marks instead of the exclamation marks. I believe that
because of this method, you the reader will deduce the answers
well before Alex Rogo succeeds in doing so. If you find the book
entertaining maybe you will agree with me that this is the way to
educate, this is the way we should attempt to write our textbooks.
Our textbooks should not present us with a series of end results
but rather a plot that enables the reader to go through the deduc-
tion process himself. If I succeed by this book to change some-
what your perception of science and education, this is my true
reward.

INTRODUCTION TO
THE FIRST EDITION
"The Goal" is about New global principles of manufacturing.
It's about people trying to understand what makes their world
tick so that they can make it better. As they think logically and
consistently about their problems they are able to determine
"cause and effect" relationships between their actions and the
results. In the process they deduce some basic principles which
they use to save their plant and make it successful.
I view science as nothing more than an understanding of the
way the world is and why it is that way. At any given time our
&
nbsp; scientific knowledge is simply the current state of the art of our
understanding. I do not believe in absolute truths. I fear such
beliefs because they block the search for better understanding.
Whenever we think we have final answers progress, science, and
better understanding ceases. Understanding of our world is not
something to be pursued for its own sake, however. Knowledge
should be pursued, I believe, to make our world better—to make
life more fulfilling.
There are several reasons I chose a novel to explain my un-
derstanding of manufacturing—how it works (reality) and why it
works that way. First, I want to make these principles more un-
derstandable and show how they can bring order to the chaos
that so often exists in our plants. Second, I wanted to illustrate
the power of this understanding and the benefits it can bring.
The results achieved are not fantasy; they have been, and are
being, achieved in real plants. The western world does not have
to become a second or third rate manufacturing power. If we just
understand and apply the correct principles, we can compete
with anyone. I also hope that readers would see the validity and
value of these principles in other organizations such as banks,
hospitals, insurance companies and our families. Maybe the same
potential for growth and improvement exists in all organizations.
Finally, and most importantly, I wanted to show that we can

all be outstanding scientists. The secret of being a good scientist, I
believe, lies not in our brain power. We have enough. We simply
need to look at reality and think logically and precisely about
what we see. The key ingredient is to have the courage to face
inconsistencies between what we see and deduce and the way
things are done. This challenging of basic assumptions is essential
to breakthroughs. Almost everyone who has worked in a plant is
at least uneasy about the use of cost accounting efficiencies to
control our actions. Yet few have challenged this sacred cow di-
rectly. Progress in understanding requires that we challenge basic
assumptions about how the world is and why it is that way. If we
can better understand our world and the principles that govern
it, I suspect all our lives will be better.
Good luck in your search for these principles and for your own
understanding of "The Goal."

I come through the gate this morning at 7:30 and I can see it
from across the lot: the crimson Mercedes. It's parked beside the
plant, next to the offices. And it's in my space. Who else would do that except Bill Peach? Never mind that the whole lot is practically empty at that hour. Never mind that there are spaces
marked "Visitor." No, Bill's got to park in the space with my title on it. Bill likes to make subtle statements. So, okay, he's the division vice-president, and I'm just a mere plant manager. I guess
he can park his damn Mercedes wherever he wants.
I put my Mazda next to it (in the space marked "Controller").
A glance at the license as I walk around it assures me it has to be
Bill's car because the plate says "NUMBER 1." And, as we all
know, that's absolutely correct in terms of who Bill always looks
out for. He wants his shot at CEO. But so do I. Too bad that I
may never get the chance now.
Anyway, I'm walking up to the office doors. Already the
adrenalin is pumping. I'm wondering what the hell Bill is doing
here. I've lost any hope of getting any work done this morning. I
usually go in early to catch up on all the stuff I'm too busy to do
during the day, because I can really get a lot done before the
phone rings and the meetings start, before the fires break out.
But not today.
"Mr. Rogo!" I hear someone calling.
I stop as four people come bursting out of a door on the side
of the plant. I see Dempsey, the shift supervisor; Martinez, the
union steward; some hourly guy; and a machining center fore-
man named Ray. And they're all talking at the same time. Demp-
sey is telling me we've got a problem. Martinez is shouting about
how there is going to be a walkout. The hourly guy is saying
something about harassment. Ray is yelling that we can't finish
some damn thing because we don't have all the parts. Suddenly
I'm in the middle of all this. I'm looking at them; they're looking
at me. And I haven't even had a cup of coffee yet.
When I finally get everyone calmed down enough to ask
what's going on, I learn that Mr. Peach arrived about an hour
before, walked into my plant, and demanded to be shown the
status of Customer Order Number 41427.

Well, as fate would have it, nobody happened to know about
Customer Order 41427. So Peach had everybody stepping and
fetching to chase down the story on it. And it turns out to be a
fairly big order. Also a late one. So what else is new? Everything
in this plant is late. Based on observation, I'd say this plant has
four ranks of priority for orders: Hot . . . Very Hot . . . Red
Hot . . . and Do It NOW! We just can't keep ahead of anything.
As soon as he discovers 41427 is nowhere close to being
shipped, Peach starts playing expeditor. He's storming ar
ound,
yelling orders at Dempsey. Finally it's determined almost all the
parts needed are ready and waiting—stacks of them. But they
can't be assembled. One part of some sub-assembly is missing; it
still has to be run through some other operation yet. If the guys
don't have the part, they can't assemble, and if they can't assem-
ble, naturally, they can't ship.
They find out the pieces for the missing subassembly are
sitting over by one of the n/c machines, where they're waiting
their turn to be run. But when they go to that department, they
find the machinists are not setting up to run the part in question, but instead some other do-it-now job which somebody imposed
upon them for some other product.
Peach doesn't give a damn about the other do-it-now job. All
he cares about is getting 41427 out the door. So he tells Dempsey
to direct his foreman, Ray, to instruct his master machinist to
forget about the other super-hot gizmo and get ready to run the
missing part for 41427. Whereupon the master machinist looks
from Ray to Dempsey to Peach, throws down his wrench, and
tells them they're all crazy. It just took him and his helper an
hour and a half to set up for the other part that everyone needed so desperately. Now they want to forget about it and set up for
something else instead? The hell with it! So Peach, always the
diplomat, walks past my supervisor and my foreman, and tells the
master machinist that if he doesn't do what he's told, he's fired.
More words are exchanged. The machinist threatens to walk off
the job. The union steward shows up. Everybody is mad. Nobody
is working. And now I've got four upset people greeting me
bright and early in front of an idle plant.
"So where is Bill Peach now?" I ask.
"He's in your office," says Dempsey.
"Okay, would you go tell him I'll be in to talk to him in a
minute," I ask.

Dempsey gratefully hurries toward the office doors. I turn to
Martinez and the hourly guy, who I discover is the machinist. I
tell them that as far as I'm concerned there aren't going to be any
firings or suspensions—that the whole thing is just a misunder-
standing. Martinez isn't entirely satisfied with that at first, and the
