  Among other things, it shows the due dates promised, along with

  the dates when Ralph expected shipment, and the dates the prod-

  ucts were actually shipped.

  "You see," I tell Jons as he studies the list on the glass top of his table, "we can predict to within twenty-four hours one way or

  the other when an order will leave the plant."

  "Yes, I've seen something like this floating around," says

  Jons. "These are the dates?"

  "Of course."

  "This is impressive," says Jons.

  "As you can see by comparing a few recently shipped orders

  with ones of a month or so before, our production lead times

  have condensed dramatically. Four months' lead time is no

  longer a holy number with us. From the day you sign the contract

  with the customer to the day we ship, the current average is

  about two months. Now, tell me, do you think that could help us

  in the marketplace?"

  "Sure it could," says Jons.

  "Then how about four weeks'?"

  "What? Al, don't be ridiculous," says Jons. "Four weeks!"

  "We can do it."

  "Come on!" he says. "Last winter, when demand for every

  damn thing we make was way down, we were promising delivery

  in four months, and it was taking six! Now you're telling me you

  can go from contract to finished product in four weeks?"

  "I wouldn't be here talking to you if we couldn't," I tell him,

  hoping desperately that we're right.

  Jons snorts, unconvinced.

  "Johnny, the truth is I need more business," I tell him.

  "With our overdues gone, and our current backlog declining,

  I've got to get more work into my plant. Now we both know the

  business is out there; it's just that the competition is getting more

  of it than we are."

  Jons looks at me through narrowed eyes. "You can really

  turn around an order of 200 Model 12's or 300 DBD-50's in four

  weeks?"

  "Try me," I tell him. "Get me five orders—hell, get me ten orders—and I'll prove it to you."

  "And what happens to our credibility if you can't come

  through?" he asks.

  Flustered, I look down through the glass table.

  "Johnny," I say, "I'll make a bet with you. If I don't deliver in four weeks, I'll buy you a brand new pair of Guccis."

  He laughs, shakes his head and finally says, "Okay, you're

  on. I'll pass the word to the salespeople that on all your products,

  we're offering terms of factory shipment in six weeks."

  I start to protest. Jons holds up a hand.

  "I know you're confident," he says. "And if you ship any new orders in less than five weeks, I'll buy y o u a new pair of shoes."

  A full moon is shining through the bedroom window and

  into my eyes. The night is still. I look at the clock beside me,

  which says it's 4:20 A.M. Next to me in bed, Julie is sleeping.

  Resting on my elbow, I look down at Julie. With her dark

  hair spilled out on the white pillow, she looks nice sleeping in the

  moonlight. I watch her for a while. I wonder what her dreams are

  like.

  When I woke up, I was having a nightmare. It was about the

  plant. I was running up and down the aisles and Bill Peach was

  chasing me in his crimson Mercedes. Every time he was about to

  run me over, I'd duck between a couple of machines or hop on a

  passing forklift. He was yelling at me from the window about my

  bottom line not being good enough. Finally he trapped me in the

  shipping department. I had my back against stacks of cardboard

  cartons, and the Mercedes was racing toward me at a hundred

  miles an hour. I tried to shield my eyes from the blinding head-

  lights. Just as Peach was about to get me, I woke up and discov-

  ered that the headlights were moonbeams on my face.

  Now I'm too much awake, and too aware of the problem I

  was trying to forget this past evening with Julie for me to fall back

  to sleep. Not wanting to awaken Julie with my restlessness, I slip

  out of bed.

  The house is all ours tonight. We started out this evening

  with nothing particular to do, when we remembered we had a

  whole house in Bearington with nobody in it to bother us. So we

  bought a bottle of wine, some cheese and a loaf of bread, came

  here and got comfortable.

  From the living room window where I stand in the dark

  looking out, it seems as though the whole world is asleep except

  me. I'm angry with myself at not being able to sleep. But I can't

  let go of what's on my mind.

  Yesterday we had a staff meeting. There was some good news

  —and some bad news. Actually, there was a lot of good news.

  High among the headlines were the new contracts marketing has

  been winning for us. We've picked up about half-a-dozen new

  orders since I talked to Johnny. More good news was the fact that

  244

  efficiencies have gone up, not down, as a result of what we've

  been doing in the plant. After we began withholding the release

  of materials and timing the releases according to the completed

  processing of heat-treat and the NCX-10, efficiencies dipped

  somewhat. But that was because we were consuming excess in-

  ventories. When the excess inventories were exhausted—which

  happened quickly as a result of the increase in throughput—effi-

  ciencies came back up again.

  Then, two weeks ago, we implemented the new smaller batch

  sizes. When we cut batch sizes in half for non-bottlenecks, effi-

  ciencies stayed solid, and now it seems as though we're keeping

  the work force even more occupied than before.

  That's because a really terrific thing has happened. Before

  we reduced batch sizes, it wasn't uncommon for a work center to

  be forced idle because it didn't have anything to process—even

  though we were wading through excess inventory. It was usually

  because the idle work center had to wait for the one preceding it

  to finish a large batch of some item. Unless told otherwise by an

  expediter, the materials handlers would wait until an entire batch

  was completed before moving it. In fact, that's still the case. But

  now that the batches are smaller, the parts are ready to be moved

  to the next work station sooner than they were before.

  What we had been doing many times was turning a non-

  bottleneck into a temporary bottleneck. This was forcing other

  work centers downstream from it to be idle, which reflected

  poorly on efficiencies. Now, even though we've recognized that

  non-bottlenecks have to be idle periodically, there is actually less

  idle time than before. Since we cut batch sizes, work is flowing

  through the plant more smoothly than ever. And it's weird, but

  the idle time we do have is less noticeable. It's spread out in

  shorter segments. Inst
ead of people hanging around with noth-

  ing to do for a couple of hours, now they'll have maybe a few ten-

  to twenty-minute waits through the day for the same volume of

  work. From everybody's standpoint, that's much better.

  Still more good news is that inventories are at their lowest

  ever in the plant. It's almost shocking to walk out into the plant

  now. Those stacks and piles of parts and sub-assemblies have

  shrunk to half their former size. It's as if a fleet of trucks had

  come and hauled everything away. Which is, in fact, about what

  happened. We've shipped the excess inventory as finished prod-

  uct. Of course, the notable part of the story is that we haven't

  filled the plant back up again by dumping new work-in-process

  on the floor. The only work-in-process out there now is for cur-

  rent demand.

  But then there's the bad news. Which is what I'm thinking

  about when I hear footsteps on the carpet behind me in the dark

  "Al?"

  "Yeah."

  "How come you're out here in the dark?"

  "Can't sleep."

  "What's wrong?"

  "Nothing."

  "Then why don't you come back to bed?"

  "I'm just thinking about some things."

  It's quiet for a second. For a moment, I think she's gone

  away. Then I feel her beside me.

  "Is it the plant?" she asks.

  "Yeah."

  "But I thought everything was getting better," she says.

  "What's wrong?"

  "It has to do with our cost measurement," I tell her.

  She sits down beside me.

  "Why don't you tell me about it," she says.

  "Sure you want to hear about it?" I ask.

  "Yes, I do."

  So I tell her: the cost of parts looks as though it's gone up

  because of the additional setups necessitated by the smaller batch

  sizes.

  "Oh," she says. "I guess that's bad, right?"

  "Politically speaking, yes," I tell her. "Financially speaking, it doesn't make a damn bit of difference."

  "How come?" she asks.

  "Well ... do you know why it looks like the cost has gone

  up?" I ask her.

  "No, not at all," she says.

  I get up to switch on a lamp and find a piece of paper and

  pencil.

  I tell her, "Okay, I'll give you an example. Suppose we have

  a batch of 100 parts. The time to set up the machine is 2 hours, or

  120 minutes. And the process time per part is 5 minutes. So we've

  invested per part 5 minutes plus 2 hours of set-up divided by 100.

  It comes to 1.2 minutes of set-up per part. According to the ac-

  E.M. Goldratt

  The Goal: A Process of Ongoing Improvement

  246

  countants, the cost of the part is based upon direct labor of 6.2

  minutes.

  "Now if we cut the batch in half, we still have the same

  amount of set-up time. But it's spread over 50 parts instead of

  100. So now we've got 5 minutes of process time, plus 2.4 minutes

  of set-up for a grand total of 7.4 minutes of direct labor. And the

  calculations are all based on the cost of direct labor."

  Then I explain the way costs are calculated. First, there is the

  raw material cost. Then there is the cost of direct labor. And

  finally there is "burden," which essentially works out to be cost of the direct labor multiplied by a factor, in our case, of about three.

  So on paper, if the direct labor goes up, the burden also goes up.

  "So with more set-ups, the cost of making parts goes up,"

  says Julie.

  "It looks that way," I tell her, "but in fact it hasn't really done anything to our actual expenses. We haven't added more people

  to the payroll. We haven't added any additional cost by doing

  more set-ups. In fact, the cost of parts has gone down since we

  began the smaller batch sizes."

  "Down? How come?"

  "Because we've reduced inventory and increased the amount

  of money we're bringing in through sales," I explain. "So the

  same burden, the same direct labor cost is now spread over more

  product. By making and selling more product for the same cost,

  our operating expense has gone down, not up."

  "How could the measurement be wrong?" she asks.

  I say, "The measurement assumes that all of the workers in

  the plant are always going to be fully occupied, and therefore, in

  order to do more set-ups, you have to hire more people. That

  isn't true."

  "What are you going to do?" she asks me.

  I look up at the window. The sun is now over the roof of my

  neighbor's house. I reach over for her hand.

  "What am I going to do? I'm going to take you out to break-

  fast."

  When I get to the office, Lou walks in.

  "More bad news for me?" I joke.

  He says, "Look ... I think I can help you out on this cost

  of products thing."

  "Yeah? Like how?"

  "I can change the base we're using for determining the cost

  of parts. Instead of using the cost factor of the past twelve

  months, which is what I'm supposed to be doing, we can use the

  past two months. That will help us, because for the past two

  months, we've had big increases in throughput."

  "Yeah," I say, sensing the possibilities. "Yeah, that might work. And actually the past two months are a lot more representative of what's really going on here than what happened last

  year."

  Lou leans from side to side. He says, "We-l-l-l, yes, that's

  true. But according to accounting policy, it's not valid."

  "Okay, but we have a good excuse," I say. "The plant is different now. We're really a hell of a lot better than we were."

  "Al, the problem is Ethan Frost will never buy it," says Lou.

  "Then why did you suggest it?"

  "Frost won't buy it if he knows about it," says Lou.

  I nod slowly. "I see."

  "I can give you something that will slide through on the first

  glance," says Lou. "But if Frost and his assistants at division do any checking, they'll see through it in no time."

  "You're saying we could end up in very hot water," I say.

  "Yeah, but if you want to take a chance. . . ." says Lou.

  "It could give us a couple more months to really show what

  we can do," I say, finishing the thought for him.

  I get up and walk around for a minute turning this over in

  my mind.

  Finally I look at Lou and say, "There is no way I can show

  Peach an increase in the cost of parts and convince him the plant

  is better off this month than last. If he sees these numbers and

  gets the idea our costs are going up, we'll be in hot water any-

  way."

  "So you want to try it?" Lou asks.

  "Sure."

  "All right," he says. "Remember, if we get caught—

  "Don't worry. I'll practice my tap dancing."

  As Lou is on his way out, Fran buzzes me to say Johnny Jons

  is on my line. I pick up the phone.

  "Hello there," I tell him,
We're practically old pals by now;

  I've been on the phone with him just about every day—and

  sometimes three or four times a day—for the past few weeks.

  "What can I do for you today?"

  "Remember our dear friend Bucky Burnside?" says Jons.

  "How could I forget good ole Bucky," I say. "Is he still complaining about us?"

  "No, not anymore," says Jons. "At the moment, in fact, we

  don't even have a single active contract with Burnside's people.

  That's the reason I'm calling. For the first time in months, they've

  expressed interest in buying something from us again."

  "What are they interested in?"

  "Model 12's," he says. "They need a thousand units."

  "Terrific!"

  "Maybe not," says Jons. "They need the whole order by the

  end of the month."

  "That's only about two weeks away," I say.

  "I know," says Jons. "The sales rep on this already checked with the warehouse. Turns out we've only got about fifty of the

  Model 12's in stock."

  He's telling me, of course, we'll have to manufacture the

  other 950 by the end of the month if we want the business.

  "Well . . . Johnny, look, I know I told you I wanted busi-

  ness, and you've pulled in some nice contracts since I talked to

  you," I say. "But a thousand Model 12's in two weeks is asking a lot."

  He says, "Al, to tell you the truth, I didn't really think we

  could do anything with this one when I called. But I thought I'd

  let you know about it, just in case you knew something I didn't.

  After all, a thousand units means a little over a million dollars in

  sales to us."

  "Yes, I realize that," I say. "Look, what's going on that they need these things so fast?"

  He tells me he did some digging and found out that the

  order had originally gone to our number-one competitor, who

  makes a product similar to the Model 12. The competitor had

  had the order on its books for about five months. But they hadn't

  filled it yet, and this week it became clear they would not be able

  to meet the due date.

  "My guess is that Burnside turned to us, because they've

  heard about us offering such fast turn-around to everyone else,"

  he says. "Frankly, I think they're desperate. And, hell, if there is

  any way we can pull this off, it'd sure be a good way for us to save

  face with them."
