Invent the Challengers

Enlarging the set of challengers before ranking any of them, because a decision is usually more sensitive to the menu than to the mathematics that ranks it.

Most people fill the alternatives slot with whatever was in the email, plus the status quo, and call the object complete. It is not.

The status quo on that list is the incumbent: the rule already running, with its documented parameters and its undocumented pad. Everything else on the list is a challenger. A challenger that nobody invents cannot win, however carefully the others are ranked.

This is the step technical people skip, because it does not look like analysis. Generating alternatives looks like sitting still, and sitting still feels like not working. So the week starts with the two options the requester named and a third that occurred to someone overnight, and that is the menu for the rest of the project. Six weeks later somebody in the meeting names a fourth that should have been obvious in hour one, and the ranking is about the wrong object again.

Decision quality is usually more sensitive to the menu than to the mathematics that ranks it. That is an uncomfortable claim for people whose skill is in the ranking.

The incoming list is a first offer

Treat it the way you already treat the incoming brief. The argument the organization is already having is useful information, because it tells you which alternatives will be in the room whether you write them down or not. It is a floor, not a ceiling. Organizations get stuck precisely because they are arguing inside a menu that cannot contain a good answer, and ranking harder inside that menu produces a more elaborate version of the same fight.

The test of whether you added enough is whether the menu now contains at least one commitment that nobody in the original request had words for.

Four habits that enlarge a menu

Relax a constraint that is not physics. Lead time is physics. “We have always used one service target” is not. “Classes are too political” is not. “Finance needs a single number for a slide” is not. You are not required to recommend the unconstrained version. You are required to put it on the list long enough to see whether it is better. If it is, the constraint was a habit rather than a limit.

Look at what good operators already do when the official rule is wrong. The planner who quietly pads one item class and starves another is running an unofficial rule. That rule is part of the incumbent, and it is also a candidate challenger: a class-based rule implemented badly, with no owner, no freeze discipline, and no record. Writing it down stops you proposing as novel something the field has been doing in the dark, and it gives you a cheap existence proof that the organization can already differentiate. Alternatives already being run badly are usually better candidates than alternatives that exist only on paper.

Unbundle. Requests glue together things that need not travel as a set. “Cut inventory 20 percent and protect fill” is two decisions wearing one sentence. “Roll it out everywhere on Friday” is a rule plus a scope plus a date. A rule at two sites is a different alternative from a rule everywhere, and a cash event this quarter is a different alternative from a rule still running in September.

Take each option to an extreme, then mix. What would you do if cash were the only thing that mattered? If stranded jobs were? Neither extreme is a recommendation. Both are ingredients, and the interesting alternatives are usually combinations the original list did not contain: protect a small class firmly, drain a large class firmly, and decline to split the difference in the middle. Skipping this produces menus of mild versions of the same idea, which cannot be ranked because they barely differ.

Beneath all four sits one question: where does the operation actually run out of room? A menu built around the wrong binding constraint can be ranked perfectly and still miss the answer, so ask it in the first hour.

Keep the hour of inventing separate from the hour of judging. Evaluating each idea as it appears keeps only the ones that already feel respectable, which in practice means keeping the email.

Every alternative is a complete strategy

An entry on the menu has to say what happens over the whole horizon on which the alternatives are scored, not just what happens on the freeze date. “Take finance’s 20 percent cut” is not yet an alternative, because it does not say what runs afterward. Written in full it is: bring every item down 20 percent by the freeze, then run the current rule at targets 20 percent lower. Only in that form can it be compared with keeping the current rule or adopting a class-based rule over the same twelve months.

Then kill most of them on purpose

A large menu is not a virtue. A large menu you then work through in full is the default week with more columns.

Generate widely so that you can screen cheaply. Two screens need no evidence. Remove any alternative that is worse than another on every interest already known: if classes everywhere on Friday cost more to install than classes at two centers this freeze, are harder to reverse, and are no better on cash or jobs, they cannot win. Remove any alternative the owner could not actually commit to this cycle. Rebuilding allocation logic in the enterprise system may be right over five years; it is not an alternative for the April freeze.

What remains should be short: the incumbent, the incoming favorite that cannot be made to disappear, and two or three invented challengers that survive the screens. More than five alternatives of the same kind entering the evidence work usually means the screening was skipped. Fewer than three usually means the inventing was.

Activities are not alternatives

The opposite failure is a list that looks rich and is not a menu: build a dashboard, improve master data, run a pilot, form a steering committee. Those are things to do, not commitments, and a menu of activities cannot be ranked because none of its entries settles anything.

The test is whether the owner could commit to the item on the freeze date and whether the process would run differently if they did. A pilot with an end date, an owner, and a rule for reading the result is a commitment. A pilot without those is an activity. When in doubt, rewrite the item as a sentence that begins with the owner and a date. If you cannot, it was never an alternative.

A menu for the April freeze

At Meridian Motors the email offered a dashboard, finance’s cut, and dealer operations’ fill target. After a page of inventing, the menu reads differently. Already in the room: keep the current rule, or take the blanket cut in full. Invented from a constraint that is not physical: replace the single service target with a class-based rule. Invented from what planners already do: write the unofficial padding into an official protected class. Invented by unbundling: adopt classes at two distribution centers this freeze and decide the rest in July, and take any cash event as a separate cut of the cheap class only. Invented from the extremes: close the unpriced expedite path, or price exceptions at the requester, neither of which changes how much is held but both of which change whether the rule on paper is the rule that runs. A dashboard, a forecasting platform, and a steering committee are not on the menu.

After the two screens, what probably remains is the current rule, the blanket cut, classes at two centers, and closing the bypass as a separate commitment if it has any chance of ranking. That goes back to Priya the same way the rewritten brief did: briefly, specifically, and in service of her freeze.

Invent first, judge second, bargain last

Bargaining before the menu exists is why rooms stall.

A position is a demand about a number, not a commitment anybody could make. Until alternatives exist that could serve more than one interest, the meeting can only split the difference: twenty and ninety-eight become ten and ninety-six, which is two slogans slightly less loud. Invent first. Judge second. Bargain last, and bargain the ranking of commitments rather than the positions that arrived in the brief.

Do not open by correcting the people who kept the pad

The unofficial spreadsheet is not a bad habit. It is information, written by people who still have to fill orders on Saturday, about what the official rule fails to do, and it should already have been read as part of the incumbent.

Name it specifically, this pad, this column, this reason they keep it, before you ask anyone to replace it. A challenger presented as a correction of somebody’s character gets padded by Friday, whatever the meeting decided.

A test you can run in five minutes

Write the current menu on one page, each entry as a complete strategy beginning with the owner and the date. Circle the incumbent. If no entry is a commitment that nobody in the original email had words for, the inventing has not started.
