I have seen a dozen decks that found margin. None of It reached the actuals.

This is the objection your case will meet, and you should raise it yourself before anyone else does. 

It is also correct. Most executives with fifteen years in manufacturing have sat through several presentations that identified millions in opportunity, approved at least one of them, and never saw the money appear in a monthly result. Their skepticism is not obstruction. It is pattern recognition, and it is accurate. 

Agreeing with it is what separates your case from the ones that came before. 

Why those cases failed 

Go back to the four layers between a loss and a funded decision. 

Losses. The physical events that consume time on the constraint. Named specifically, from your own asset. 

Measurement. A counting method someone else could repeat and land in the same place. 

Translation. Hours at the constraint converted to contribution margin, with the margin figure confirmed by finance. 

Decision. A named owner, a funded action, a date, and the place the result is expected to appear. 

Failed cases perform the third layer alone. 

They arrive with a benchmark, a percentage, and a multiplication. The arithmetic is usually correct. What is missing is any evidence that the losses were observed rather than assumed, any method a challenger could repeat, and any commitment about who will do what by when. 

So the number is interesting rather than actionable. It gets a good reception, occasionally it gets funded, and then it disperses, because nothing in the case ever specified where it was supposed to land. 

The tell 

You can spot a third layer only case in about thirty seconds. 

It cites an industry figure rather than a measurement from the plant in question. It presents a range instead of a number. It proposes a program rather than an action. It has no owner named anywhere in it. And it never says which line of which report will move, in which month. 

Every one of those is a symptom of the same thing: analysis performed at a distance from the asset. 

What holding all four layers actually buys you 

It changes what you are asking for. 

A third layer case asks the committee to believe a number. That is a hard thing to ask, and belief is exactly what a skeptical executive has learned not to extend. 

A four layer case asks the committee to make a decision. The number came from two weeks of counting on a named asset. The method is written down and repeatable. The margin figure came from finance. The action has a cost, an owner, and a date, and there is a specific place the result will show up where anyone can check. 

None of that requires belief. It requires a yes or a no, and it is perfectly acceptable to get a no, because a no arrives with a reason you can work with. 

What you already have 

If you have followed the last five weeks, you have all four layers on one asset. 

You have named categories from your own counting. You have a method you could hand to a colleague. You have hours converted to contribution margin at a rate finance confirmed in writing. And you have three priced actions ranked by cost per hour recovered. 

What remains is assembling it into something a busy executive will read, which is a smaller task than the five weeks that preceded it.
