At 08:41 on a Tuesday, the general counsel of a law firm's biggest client sends a four-line email. Her company's regulatory filing was missed — by the firm — and she learned it from the regulator's notice, not from her lawyers. She wants an explanation in writing by noon and a call at five. Her last line: "We have been approached by another firm and, as of this morning, I am listening."
That's the opening of The Keystone Account, a fictional teaching case we wrote and publish free (it's on the starter shelf in every CaseConduit account, teaching note included). Eleven-year relationship, 22% of the firm's revenue, a penalty that's probably appealable, a managing partner who won't move on fees, and an associate who warned about the exact failure — twice, in writing.
Format 1: Watch it — the animated story
Before anyone can argue about a case, they have to know it. The traditional answer is assigned pre-reading, and the traditional result is that half the room skimmed it. The Keystone case exists as a 90-second animated, narrated story — the crisis landing on the relationship lead's desk, scene by scene — generated from the written case.
What it trains: nothing, honestly. That's the point. It's the briefing format — it gets thirty people to the same starting line in two minutes, which is what makes every format below work with a cold room.
Format 2: Triage it — the crisis inbox
It's 09:00 and the inbox is filling: the GC's ultimatum, the managing partner's constraints, the associate who flagged the risk asking if she's in trouble, a partner who wants to "manage the message." You answer them, in whatever order you choose, against the clock — and the order is the lesson. Does the urgent, angriest email get your first reply or your best reply? Does the junior get protected or parked?
What it trains: prioritisation under pressure, and written judgement — every reply is scored on honesty, sequencing and what it commits to. People who are excellent in discussion are often shocked by what they write at speed.
Format 3: Chair it — the boardroom
The response committee meets. The managing partner is there ("I will not haggle away this firm's rate card to apologise for a diary error"), and the AI plays him — out loud. You chair: what does the firm admit, offer, refuse? The characters push back with their own agendas, and a running score tracks whether you're building a package or just surviving a meeting.
What it trains: the meeting-room skills the written case method famously can't — interruption, alliance, holding a line while someone senior leans on it.
Format 4: Take the call — five o'clock, face to face
Everything reduces to one conversation: the GC, on a video call, opens with "Eleven years, and I find out from the regulator — not from you. You have this call to change my mind. Go." She answers out loud, she notices hedging, and she lets silences do the work. There is nowhere to hide and no committee to defer to.
What it trains: the single hardest professional skill — owning an error, specifically and without flinching, while giving your counterpart something they can defend to their board. It's the difference between an apology and a package.
Format 5: Litigate it — the courtroom counterfactual
And if five o'clock fails? The Keystone case has a dark timeline: the client leaves, abandons the penalty appeal, and sues. The courtroom format plays that dispute — candour about the admitted error against exaggerated loss claims, with the associate's written warnings cutting both ways: proof the firm was warned, and proof it surfaces problems honestly.
What it trains: consequence. Playing the litigation after playing the call is the most persuasive argument for handling the call well that we know of.
What this adds up to
Five experiences, one set of facts, wildly different lessons — sequencing, negotiation, candour, chairing, consequence. In a classroom they chain: watch the story, vote on what the firm should offer, play an act, vote again and watch the room's answer move, play the next act, then reveal the epilogue. That whole arc exists as a one-click, ready-made session in our EducatorLab, and the full written case — four exhibits, teaching note, the lot — is free on the starter shelf.
The case method's founding insight was that people learn judgement by inhabiting decisions, not hearing about them. For a century, "inhabiting" meant a well-run discussion. It can mean more now. The case study isn't the end of the pipeline any more — it's the source code.
The Keystone Account is fiction; any resemblance to real firms or people is coincidental. It's free to teach with — create an account and it's on your shelf.
