The Goal – Chapter 25 – “Stop Futile Work!”

[The fastest way to read The Goal, and the absolute fastest way to learn The Theory of Constraints.][Watch a video summary.]

Jonah is retrieved from the airport and supports the team at the plant.

Highlight

“What you’re saying is that making an employee work and profiting from that work are two different things.”

Ineffective employee time has a second trap – it creates future work that continues to be off target. Stopping bad direction work is a huge relief on an organization.

P203 – “Before we jump to conclusions, let’s invest half an hour to go into the plant so we can find out what’s happening,” Jonah says.

P204 – “You know, I would guess, just from looking at it, that you have at least a month or more of work lined-up here for this machine.

P205 – “But let’s say you need only 450 hours a month, or 75 percent, of Y to keep the flow equal to demand. What happens when Y has worked its 450 hours? Do you let it sit idle?”

P206 – “Excess inventory,” says Stacey.

P207 – Bob shrugs and says, “We build the orders and ship them.” “How can you?” asks Jonah.

Money cannot be made without the part as the constraint.

P208 – As he says this, I’m thinking to myself about the finished goods we’ve got crammed into warehouses.

Warehouses full of inventory are an operations and financial red flag.

P209 – “A major constraint here in your system is this machine,” says Jonah.

“When you make a non-bottleneck do more work than this machine, you are not increasing productivity. On the contrary, you are doing exactly the opposite. You are creating excess inventory, which is against the goal.”

“But what are we supposed to do?” asks Bob. “If we don’t keep our people working, we’ll have idle time, and idle time will lower our efficiencies.”

“So what?” asks Jonah.

Jonah is calling out the importance of cadence. It doesn’t make sense for the plant to outwork the constraint.

P210 – Then Ralph suggests, “What you’re saying is that making an employee work and profiting from that work are two different things.”

P211 – “We’re releasing material faster than the bottlenecks can process it.”

Creating inventory that cannot be advanced has no purpose. It is makework. Many companies make this mistake with projects – kicking off projects that cannot be completed.

The Goal – Chapter 24 – Champagne Room, Julie

[The fastest way to read The Goal, and the absolute fastest way to learn The Theory of Constraints.][Watch a video summary of Chapter 24.]

Rogo’s team achieves several major milestones and celebrates in response. Julie shows up, jumps to conclusions, and runs away from her problems as usual. Jonah returns to provide more guidance at the plant.

Highlights

“The bottlenecks have spread.”

In this re-reading, I found this line confusing. Cells at Rogo’s plant are producing out of cadence with the constraint, creating interim bottlenecks. This is a somewhat absurd situation – why would anyone do that? Perhaps it is an indication of how much wisdom has been spread since The Goal was first published.

Page by Page

P195 – “Here’s to a new plant record in shipments of product,” he says.

“Not only did we ship more product,” says Stacey, “but, having just calculated our inventory levels, I am pleased to report that between last month and now, we’ve had a twelve percent net decline in work-in-process inventory.”

P196 – “The reason I called is I know how I’m always on your case when things go wrong, Al, so I just wanted to tell you thanks from me and Jons for doing something right,” says Peach.

P197 – “You bastard!”

P198 – “Look, why don’t I talk to her.”

Often times the messenger is as important as the message.

P199 – “The bottlenecks have spread.”

P200 – If the demand on another work center has gone above one hundred percent, then we’ve created a new bottleneck.

Last week, for the first time since I’ve been at this plant, you could actually walk over to the assembly line without having to turn sideways to squeeze between the stacks and bins of inventory.

P201 – Jonah says, “Maybe I’d better come have another look.”

The Goal – Chapter 23 – Goldratt on Data Collection

[The fastest way to read The Goal, and the absolute fastest way to learn The Theory of Constraints.][Video summary of Chapter 23.]

Mike Haley’s forearms are huge and from his role as second shift he makes major contributions to freeing up the plant’s constraint at the furnace. Nakamura, Rogo’s faithful data analyst, is doing whatever he can create usable information.

Highlight

“And if what you say is true, that this operation is so vital to the plant, then it seems to me we ought to have valid statistics on it.” Nakamura

If data is required, and it doesn’t exist – then collecting data is the constraint.

Page by Page

P185 – “He’s been coming around and asking all kinds of dumb questions.”

P186 – “And if what you say is true, that this operation is so vital to the plant, then it seems to me we ought to have valid statistics on it.” Nakamura

P187 – “A few days ago on my own, I did some projections of how many shipments we would actually be able to make last week based on the output of parts from the bottlenecks.”

Ambition and initiative are hard to coach – support team members that show them. Prediction based on calculation is an important part of using data.

P188 – “You see, I asked some of the hourly people down there and they told me those kinds of delays happen a lot in heat-treat.”

P189 – “When it stops, they can get to work on it immediately.”

This is not what happens on the NCX-10. Mike Haley runs his team like a NASCAR pit crew – perfect for the constraint.

P190 – “But what happens if stealing people turns non-bottlenecks into bottlenecks?”

Solve the current problem before you earn the right to worry about the next one. It is common to find people stuck in this scenario – they let a future problem stop them from making the right move now.

P191 – “From now on, we put only our best people to work on the bottlenecks.”

“Shortly thereafter, some amazing things happen.”

Incentives on heat treat make an impact. Goldratt supports many management best practices through the book.

P192 – “Well, we could do even better if I could get someone to listen to an idea I got,” he says.

P193 – “We don’t need to get an engineering change order, because we already have an approved procedure on the books,” says Bob.

Bypass of heat treat on parts for metal shaving allows the constraint to be further freed up.

Mike Haley has huge forearms and addresses one of the plant constraints. Nakamura could use big forearms to enter the data he collects.

The Goal – Chapter 22 – Constraint Tactics

[The fastest way to read The Goal, and the absolute fastest way to learn The Theory of Constraints.][Watch a video summary of Chapter 22.]

This chapter starts and ends at the plant. Most of the dialog is about pragmatic implementation of Theory of Constraints principals.

Highlight

“I want recommendations on offloading the bottlenecks ready for our Wednesday staff meeting.”

Rogo doesn’t solve the problem – he asks his team how they would solve it.

Page by Page

P180 – “The bottlenecks are getting their parts promptly.”

Less inventory! Fully utilized constraints! Great job.

P181 – “I want recommendations on offloading the bottlenecks ready for our Wednesday staff meeting.”

Goldratt doesn’t focus on teamwork explicitly – but this is one of several times that Rogo finds the solution with a team, rather than doing it on his own.

“What we need is a simple way to show people the parts they need to treat with special attention—the ones they need to treat like gold.”

Making it easy for people to do the right thing improves the odds of success.

P182 – “Meet me on the receiving dock.”

P183 – “So this must be one of the machines you told Jonah we sold to make way for the inventory holding pen,” I say.

The Zmegma, found and shut down at another plant, opens up capacity as a step. Small improvements in constraint capacity make a big impact.

P184 – “With all the paperwork he’d have to do, it was too much trouble to sell it to us.”

Donovan discloses that bureaucracy was a constraint to learning and making money off of a line relocation.

The Goal – Chapter 21 – Working the Constraint

[Learn the goal fast, with the best chapter-by-chapter summary.] [Watch a video summary of Chapter 21.]

Alex asks Julie on a date – it is touching. The plant is learning how to focus on constraints.

Highlight

When you’ve finished the bottleneck parts, you can go back to what you were doing before.

The right to work on something outside of the constraint is earned.

Page by Page

P170 – All she can do is say no, right?

P171 – “And about ninety percent of the current overdues have parts that flow through one or both of the bottleneck operations.

P172 – “I don’t want to see either of you working on something not on that list.

P173 – “Why the hell isn’t that machine working?” I ask him.

P174 – It turns out, as Bob explains to me, that the parts they were waiting for at the NCX-10 have been sitting there for about a week.

P175 – So by continuing to run the non-bottleneck parts, this guy was actually interfering with our ability to get an order out the door and make money.”

P176 – We’re holding fifteen-minute meetings with everyone working in the plant, both foremen and hourly people.

P177 – When you’ve finished the bottleneck parts, you can go back to what you were doing before.

The Goal – Chapter 20 – Bob Donovan Coaches Change, Julie Rogo Waffles

[Click for a chapter-by-chapter summary of the whole book.] [Video summary of Chapter 20.]

Rogo starts at the plant and then travels to meet with his wife in another tempt to recognize. You’re at Chapter 20 of 40 – 1/2 way done!

Highlight

“Why don’t we go ahead with the easier things right away and see what kind of effect they have while we’re developing the others.”

Small initial success with change sets the scene for future success.

Page by Page

P162 – “If you hadn’t neglected her all these years, you wouldn’t be in this situation,” she says.

This comment from Rogo’s Mother in Law is painful, but accurate.

P163 – “Why don’t we go ahead with the easier things right away and see what kind of effect they have while we’re developing the others.”

Bob Donovan speaks wisdom on change.

P164 – “Build inventory to maintain efficiencies.”

Our problem is our backlog of overdue orders.

P165 – “Nothing else takes priority over this.”

Rogo makes it clear to his team what his priorities are.

P166 – “If you want to talk to Julie, you can do it through her lawyer,” says Ada.

Wow. Julie has escalated quickly.

P167 – “Everyone except me knows what I should do.”

If you’re in this situation – then just do those things until you figure out your plan. Stopping to take a break or flee from the problems is rarely the right move.

P168 – “The longer you stay away, the more we’re going to drift apart from each other and toward a divorce.”

Like the deadline he got from Peach – Rogo might as well state his options.

The Goal – Chapter 19 – Change

[What every MBA should know about The Goal.] [Link to video summary.]

Rogo begins the chapter at home and picks Jonah up from the airport.

Highlight

“Alex, there are two ways that the ideas I’m giving you won’t work. One is if there isn’t any demand for the products your plant makes.”

“I also can’t help you if you’re determined not to change.”

These situations are difficult to fix:

  • No product demand,
  • Culture prevents change.
  • Avoid them.

Page by Page

P149 – “We found out we’ve got some problems at the plant which we might not be able to solve.”

Double constraints.

P150 – “But you have to learn how to run your plant by its constraints.”

“Alex, there are two ways that the ideas I’m giving you won’t work. One is if there isn’t any demand for the products your plant makes.”

“I also can’t help you if you’re determined not to change.”

P151 – “Most manufacturing plants do not have bottlenecks. They have enormous excess capacity.” Spoken by Jonah to Alex at airport.

“To increase the capacity of the plant is to increase the capacity of only the bottlenecks.”

P152 – “And I suggest that first of all we go into your plant and see for ourselves exactly how you are managing your two bottlenecks.”

Spoken by Jonah to team – a manufacturer’s products come from the plant floor. Solve problems where they live.

“The six of us put on the safety glasses and hats and go into the plant.”

Safety first!

“I notice Jonah’s eyes measuring the stacks of inventory piled everywhere.”

Inventory status and hand kept statistical process control graphs are great ways to understand a plant.

P153 – Jonah says, “So talk to them. They have a stake in this plant. They’re not stupid. But you have to make them understand.”

NCX-10 is a constraint, but it is being left idle during union lunch breaks.

P154 – “There are,” says Stacey, “but going outside would increase our cost-per-part.”

The expression on Jonah’s face says he’s getting a little bored with this stonewalling.

Jonah asks about external sourcing for heat treat.

Goldratt’s 9 Layers of Resistance is a great way to tackle objections like Stacey raises around heat treat.

P155 – “I’ll put my question differently: how many products are you unable to ship because you are missing the parts in that pile?”

Rogo is asking, “what specific parts constrain revenue?”

P156 – “One million dollars,” I say with awe. “On one condition!” says Jonah. “That you get these parts in and out of heat-treat and shipped as a finished product before your customers get tired of waiting and go elsewhere!”

P157 – I ask, “You mean we should put Q.C. in front of the bottlenecks?”

“Every time a bottleneck finishes a part, you are making it possible to ship a finished product.”

Thinking through quality control is a common way to free up capacity at a constraint.

P158 – “The true cost is the cost of an hour of the entire system.”

P159 – “First, make sure the bottlenecks’ time is not wasted,” he says.

P160 – I say, “Well, actually, you and the kids were on the right track at dinner.” “We were?” asks Dave. “We need to make the Herbies go faster,” I say.

Julie is off – listening to violin music in the background like Scoobie Doo.

The Goal – Chapter 18 – An "Aha!" Moment on Constraints

[The fastest way to read The Goal, and the absolute fastest way to learn The Theory of Constraints.] [Video summary of Chapter 18.]

We start with grandma Rogo and move back to the plant for some inspection and review of lines and products.

Highlights

“I don’t know. We’ve never done it that way before.”

Planning for a new product often identifies an optimal or near – perfect approach. But that is seldom put into place. Rarely does the planning to figure out ‘perfect’ happen. Rarer still is this implemented. Just do that. Even if it isn’t perfect – often that attempt is close enough!

Page by Page

P136 – She tells us stories about the Depression and how lucky we are to have food to eat.

P137 – “This combination of dependency and fluctuations is what we’re up against every day,” I tell them. “I think it explains why we have so many late orders.”

An operations team that only plans for best case outcomes will often disappoint their customers.

P138 – “We should be trying to optimize the whole system.” On phone to Jonah.

“A bottleneck,” Jonah continues, “is any resource whose capacity is equal to or less than the demand placed upon it. And a non-bottleneck is any resource whose capacity is greater than the demand placed on it. Got that?”

The wisdom here is to focus on the system output, rather than a single step. Know your goal. Know how a current step advances you to the Goal.

P139 – “What you need to do instead is balance the flow of product through the plant with demand from the market.”

“No, bottlenecks are not necessarily bad—or good,” says Jonah, “they are simply a reality. What I am suggesting is that where they exist, you must then use them to control the flow through the system and into the market.”

Constraints and bottlenecks are present – they just exist! Any forced ranking of process speeds will have winners and losers. No need to punish the constraint – because their must be a constraint.

P140 – “I guess we look at all our resources,” I say, “and compare them against market demand.”

P141 – “It’s the complete product mix for the entire plant, including what we “sell” to other plants and divisions in the company.”

For those familiar with The Lean Startup – these are Vanity erp and Oracle metrics.

P142 – Yesterday, for instance, we found the demand for injection molding machines is about 260 hours a month for all the injection molded parts that they have to process. The available time for those machines is about 280 hours per month, per resource. So that means we still have reserve capacity on those machines.

But the more we get into this, the more we’re finding that the accuracy of our data is less than perfect.

“The problem is, we’ve been under the gun so much that a lot of the updating has just fallen by the wayside,” says Stacey.

There is a Texas saying – You can either do it, or get credit for it.

All systems struggle with accurate and consistent measurement. Effort can either drive results or reporting, but there is always a trade off.

P143 – Can’t we come up with some other faster way to isolate the bottleneck—or at least identify the candidates?

“If we’ve got a Herbie, it’s probably going to have a huge pile of work-in-process sitting in front of it.”

Bingo! Stop and look around. The Herbie is probably obvious to the team on the floor.

P144 – “But this is supposed to be one of our most efficient pieces of equipment,” I say.

… supposed to be…

Again, we find ourselves at the NCX-10. There is another story within the Goal where the sunk cost fallacy is explored. It is okay to make one bad decision – not okay to make a second one.

P145 – This one looks more like what you might think of in terms of an industrial Herbie. It’s dirty. It’s hot. It’s ugly. It’s dull. And it’s indispensable.

[And similar processes live in every plant.]

P146 – “What’s the problem here—we need bigger furnaces?” I ask. Bob says, “Well . . . yes and no. Most of the time these furnaces are running half empty.”

Common sense questions are getting candid, but wrong, answers. This topic will come back.

P147 – “Okay, but if we filled the furnace every time, would we have enough capacity to meet demand?” I ask. Bob laughs. “I don’t know. We’ve never done it that way before.”

If there is an obvious clear “right way” and no one has ever done it – give it a shot. This is a common occurrence. Do the obvious right thing.

The Goal – Chapter 17 – Dependency in the Plant

[Click for a chapter-by-chapter summary of the whole book.] [Click for the video summary.]

We start at the Rogo home, then move to the plant where a subassembly needed by Smyth requires attention.

Page by Page

P124 – “Even I know how to make pancakes.”

Sharon to Davey – it’s hard not to like good sibling rivalry. This statement also illustrates the importance of training!

P125 – “Because I’m not going to have my people do two setups for final assembly on account of your lateness.”

This is poor team behavior based on Goldratt’s definition of team seen in Chapter 15. If multiple setups eases the constraint – do it!

P126 – “But how do you know these things are really going on out there in the plant?”

Fluctuations and dependency – covered in Chapter 11 – are apparent everywhere once the concepts have been explained.

P127

“It’s okay to say that fluctuations in cycle time for a robot would be almost flat while it was working,” I tell him.

P128

“And if we know that Jonah is correct, we’d be pretty stupid to continue running the plant the same way as before—right? So I’m going to let you see for yourselves what’s happening.

P129

“We also have dependent events, because the robot cannot begin its welding until the materials handler has delivered the pieces from Pete’s department.”

P130

I tell his secretary the sub-assemblies will definitely arrive at his plant tomorrow, but that’s the best we can do—unless Hilton wants to pay for a special shipment tonight.

P131

“Let’s go see what’s really going on out there,” I say.

P132

I went around and told them how important this shipment is, and they really put themselves into it.

P133

“But when Pete delivered 28 pieces, the robot could still only do twenty-five.”

P134

“The maximum deviation of a preceding operation will become the starting point of a subsequent operation.”

It didn’t matter that Pete got his hundred pieces done, because we still couldn’t ship,” I say.

The Goal – Chapter 16 – Why hate Julie Rogo?

[I need to read The Goal fast, and the Theory of Constraints.][Video summary of Chapter 16.]

The most important part of this chapter is that we learn Rogo’s daughter’s name – Sharon. Julie is not a likable character, but as someone who has experienced similar relationship issues it might be that these scenes hit too close to home.

This is a bridge chapter like 7 and 12.

Page by Page

P120 – Al, I can’t handle always being last in line for you.

[Should he prioritize her as he had the efficiency of the NCX-10 before Jonah’s teachings? /sarcasm]

P121 – “Is Mommy still mad at me?”

P122 – “What did you do to her?” yells her mother.

P123 – “I’m very worried about her.”

It is reasonable to worry about any adult that flees from a problem and sheds their obligations as a parent. This is why Julie is so unlikable.
