1. For the instructor

This is a ready-to-run 75-minute class you can teach cold, with no prep. Students look at one composite (invented) company that is quietly doing three things at once, decide which single thing it should pour its small team into, and defend cutting the other two — including a tempting, press-worthy one — out loud against the rest of the room. It is built for a wide, mixed group: no business background is assumed, every term is defined the first time it appears, and the work is done in small tables so quiet students can contribute through their group.

The one idea the whole class turns on is the focus trade-off: a small team has a fixed stock of people, time, and money, so every “yes” to one thing is a silent “no” to another. Choosing well is mostly about the no — declining good, tempting opportunities so the one thing you can actually win gets enough of the team to win it. The trap the class exposes: the option that feels most exciting — the one with press, a famous name attached, or fast easy revenue — is often the one whose true cost is highest, because it pulls the team off the bet that is actually working.

What’s in the pack: this run-of-show (section 4), the concepts you need and nothing more (section 5), a group exercise with a facilitator answer key you can run without being a strategy expert (sections 6-7), Socratic debrief prompts (section 8), a printable student handout (section 9), a stretch for fast tables (section 10), and a slide outline you can present straight from (section 11).

How to run it in a mixed room: keep tables to 3-5 students, mix majors on purpose, and make each table commit to a call before the debate — the learning is in defending a decision, not in finding a “right” answer. There is no single correct option to name; there is a most defensible reading, and section 7 gives it to you along with what each other choice would cost.

One honest line, say it aloud at the start: this is teaching material, not a certification and not a credit-bearing course. It builds the skill of pricing a tempting “yes” against what it quietly costs; it does not issue any credential.

A note on the clock. The run of show below is a tight 75 minutes with little slack — in a 30–40 student room budget ~85 minutes in practice (set-up, table-forming, and report-backs always run long). If you fall behind, cap report-backs at two tables and cover two of the discussion prompts. Protect the group exercise and the answer-key debrief — those are the session.

2. Session at a glance


Audience	Capstone / mixed majors; no business background; good for debate
Class size	12-40 (tables of 3-5)
Total time	75 minutes
Materials	Printed student handout (section 9); board or slides (section 11); a timer

By the end students can:

Explain the focus trade-off — why a small team wins more by concentrating on one target than by chasing several — and name the failure mode of spreading: thin everywhere, strong nowhere.
Price a tempting “yes” in opportunity cost — see that the real cost of taking on an option is the best thing you gave up to do it, not the cash or glamour it brings in.
Make and defend one call: which single bet the team should focus on, and why cutting the other two — including the exciting one — is the right “no, not yet.”

3. The case

Sprout is a composite (invented) company; every figure below is illustrative and chosen for clean reasoning, not drawn from or claimed about any real firm.

Sprout makes a phone app that plans a week of family dinners in a few taps and turns the plan into one tidy shopping list. Busy parents love it. But Sprout has quietly grown into doing three different things at once, because each one looked like growth when it started. It has a team of 8 people and about 10 months of runway (the money it has left before it must raise more or break even). Here is where the team’s effort currently goes (all figures illustrative):

The three bets Sprout is running at once	Figures (illustrative)
A. The core app — meal planning for busy parents	40,000 active families; growing ~15%/month; parents stay ~14 months
B. Restaurant partnerships — letting local restaurants sell meal kits through the app	3 restaurants signed; a well-known local chef publicly keen; lots of press, almost no revenue yet
C. Corporate wellness — selling the app to employers for their staff	1 signed pilot with a mid-size employer; promises steady monthly revenue, but needs admin dashboards and security features Sprout hasn’t built

To build any one of these to a genuinely winning standard takes about 5 of the 8 people for roughly 6 months. Split across all three, each bet gets barely two or three people — and after a year Sprout would have a core app losing its momentum, a half-built restaurant feature, and a stalled corporate pilot: three near-misses instead of one clear win.

The founder has to choose one bet to concentrate the team on, and say “not yet” to the other two. The pull is that the restaurant partnership is the exciting one — a famous chef, press, a story everyone wants to keep telling — so cutting it feels like walking away from the best part. That is the call the class will make: which one to focus on, and how to defend the cut.

4. Run of show

8 min — Hook. Pose the situation aloud (or read Slide 2): Sprout is loved by parents but is quietly running three bets at once with a team of 8, and everything is slipping. Quick hands-up poll: “Should Sprout keep all three going, or cut down to one?” Note the split on the board; you’ll return to it.
10 min — Frame + teach. Walk section 5’s concepts using Slides 3-5: the focus trade-off, why focus beats spreading thin, opportunity cost as the price of a yes, and “no, not yet.” Keep it fast — the tables will use the ideas, not memorize them.
5 min — Set up the exercise. Hand out the worksheet (section 9). Read the task: score each of the three bets, pick the ONE to focus the team on, and name what cutting the other two costs. Assign tables.
22 min — Group work. Tables argue it out and fill the worksheet. Circulate; use the “steer a stuck table” notes in section 7. Each table must commit to one bet before the debate.
15 min — Structured debate. Two or three tables that chose differently present their call; the room challenges. Force each table to name what cutting the tempting option (the restaurant partnership) would cost — and what keeping it would cost.
10 min — Debrief + reveal. Walk the facilitator answer key (section 7) and Slides 6-8. Return to the opening poll and ask who changed their mind and why.
5 min — Takeaway + close. Land the one-sentence takeaway (section 8) and point students to the anchor course for solo practice.

Total: 75 minutes.

5. Teaching points

Teach only these — they are everything the section 7 call needs.

The focus trade-off. A small team has a fixed stock of people, time, and money. Because that stock is fixed, saying “yes” to one thing is saying “no” to another — there is no spare team hiding somewhere. The trade-off is real whether or not you name it; the only choice is whether you price it on purpose or let it happen by accident.
Focus beats spreading thin (diffusion). Diffusion means spreading a small team across many targets. It produces work that is thin everywhere and strong nowhere — several half-built things, none good enough to win. Concentrating the same team on one target ships one thing that actually wins, and a win compounds: happy customers who bring the next ones, a product shaped deeply to one real need, and a team that has learned one thing cold. Same people, same year — one clear win, or several near-misses.
Opportunity cost — the real price of a “yes.” The true cost of taking on an option is not the cash or effort it uses; it is the best thing you gave up to do it. For a team that is the binding constraint — where every person on bet B is a person taken off bet A — this is the number that matters. A tempting option can look clearly worth it on its own cash or press, yet cost you the one win you were about to get. That displaced win is on no line you can point at, which is exactly why unpriced “yes” decisions quietly bleed a small team.
The tempting option is the dangerous one. The bet that feels strongest — press, a famous name, fast easy money — is often the one whose opportunity cost is highest, because excitement pulls the team off the bet that is actually working. “It’s exciting” and “it’s real revenue” are not reasons to keep something; the test is whether it advances the one thing you are trying to win.
“No” means “not yet,” not “never.” Cutting a good option to focus is time-bound. You decline now because a scarce team can only win one thing at a time, and you revisit the others from a position of strength once the first bet is won. A disciplined “no” names the one change in the facts — the core bet turning out weak, or fresh money removing the team as the constraint — that would flip it.

6. Group exercise

The task. Your table is Sprout’s leadership. The team of 8 cannot win three bets at once. You must choose ONE bet to concentrate the team on for the next 6 months, cut the other two to “not yet” — and be ready to defend the cut against a table that chose differently.

Handout: use the worksheet in section 9. Work in these steps.

(Score each bet — together) For each of the three bets (A core app, B restaurant partnerships, C corporate wellness), write one line on each of: Traction — is it already working with real customers? Fit — does it use what Sprout is already good at, or need things the team hasn’t built? Momentum cost — what does the core app lose if the team’s attention goes here instead?
(Price the tempting one) Bet B (restaurants) is the exciting one — a famous chef, press. Write one sentence on its opportunity cost: if 5 of the 8 people build restaurant features for 6 months, what is the best thing Sprout gives up? Name it, don’t just say “revenue.”
(Make the call) Circle ONE bet to focus the whole team on: A, B, or C. The other two are cut to “not yet.”
(Defend the cut) Write one sentence on what cutting the tempting option (B) costs Sprout — and one on why that cost is worth paying. You’ll say both out loud in the debate.

Every table must commit to one bet before the debate. There is no prize for the “right” letter — the point is the reasoning, and how honestly you price what you cut.

7. Facilitator answer key

The defensible call: focus the whole team on A, the core app — the bet that is already working — and cut B (restaurants) and C (corporate wellness) to “not yet.” Here is why, and what each option would cost.

Run the three bets through the focus trade-off. A, the core app, is the only bet with real traction: 40,000 families, growing ~15% a month, staying ~14 months. It fits what Sprout is already good at, so 5 people aimed at it for 6 months deepen a win that is genuinely within reach. B, restaurant partnerships, is the tempting trap: a famous chef and press make it feel like the future, but it has almost no revenue, needs bespoke features for each restaurant, and serves a different customer than the parents Sprout is winning. Its opportunity cost is the core app’s momentum — pull 5 people onto restaurant features and the one bet that is working stalls just as it is compounding. C, corporate wellness, is the plausible distraction: one pilot and the promise of steady revenue are real, but it demands admin dashboards and security work Sprout hasn’t built, dragging a small consumer team into becoming a half-baked enterprise vendor.

What each choice costs. Choosing B spends the team’s whole effort on glamour and story while the paying, growing core goes cold — the highest-cost option wearing the most exciting face. Choosing C trades a working consumer product for a slow, feature-heavy B2B build the team isn’t staffed for, and still leaves the core untended. Choosing A has a real cost too, and the table must name it: Sprout walks away — for now — from the chef, the press, and a signed corporate pilot, and some of that goodwill may cool. But that is the price of a win instead of three near-misses, and “not yet” keeps both B and C open to revisit from strength once the core app is clearly won.

Steering a stuck table. If a table is dazzled by the chef and the press, ask: “press, or 40,000 paying families growing every month — which is the bet that’s actually working?” If a table likes C for the “steady revenue,” ask: “who builds the security features, and what happens to the core app while they do?” If a table wants to keep all three “just a little,” name it as the exact spreading- thin trap — a small team split three ways wins nothing. If a table picks A but can’t say what cutting B costs, push them: a good “no” prices what it gives up out loud.

8. Discussion & debrief

Run these after the tables report out:

Which bet tempted your table first — and what tipped you off that “exciting” and “worth keeping” are not the same thing?
Bet B has a famous chef and lots of press. Name exactly what that buys Sprout this year — and what it costs the core app. Which is bigger?
Someone says: “But the corporate pilot is signed revenue — how can saying no to money be right?” What is the money-in-hand argument missing?
You cut B and C to “not yet.” Name the one change in the facts — about the core app, or about Sprout’s runway — that would make keeping B or C the right call instead.
Sprout’s team is 8 people. If it were 800, would the answer change? What does that tell you about when the focus trade-off bites hardest?

One-sentence takeaway: The real cost of a tempting “yes” is the best thing you quietly gave up for it — so the hardest, most valuable strategic move is a well-priced “no.”

9. Student handout

Sprout — the situation (composite; all figures illustrative). Sprout makes a phone app that plans a week of family dinners and turns it into one shopping list. Busy parents love it. But Sprout is quietly running three bets at once with a team of 8 people and about 10 months of runway (money left before it must raise more or break even).

The three bets	Figures
A. Core app — meal planning for busy parents	40,000 active families; growing ~15%/month; parents stay ~14 months
B. Restaurant partnerships — restaurants sell meal kits in the app	3 signed; a famous local chef keen; lots of press, almost no revenue
C. Corporate wellness — sell the app to employers for staff	1 signed pilot; promises steady monthly revenue; needs admin + security features Sprout hasn’t built

Building any one bet to a truly winning standard takes about 5 of the 8 people for ~6 months. Split across all three, each bet gets two or three people and none of them wins.

Your task. Choose ONE bet to focus the whole team on for 6 months. The other two are cut to “not yet.” Then defend the cut — especially cutting the tempting one.

Two ideas to use: Opportunity cost = the best thing you gave up to say yes (not the cash it brings in). Spreading thin = a small team on too many targets ends up strong nowhere.

Bet	Traction (working now?)	Fit (uses our strength?)	What the core app loses if we focus here
A. Core app
B. Restaurants
C. Corporate wellness

Price the tempting one. If 5 people build restaurant features (B) for 6 months, the best thing Sprout gives up is: ______________________________________________

The call — circle one. Focus the whole team on: A B C

Defend the cut. What does cutting the tempting option cost, and why is it worth paying?

10. Stretch

For tables that finish early:

Find the flip. You cut the restaurant partnership. What single fact, if you learned it, would make focusing on B the right call after all? (Hint: think about what would have to be true about the core app’s growth, or about how much of the team the restaurant work really needs.)
When is a “yes” free? The corporate pilot (C) looked costly because it pulls people off the core. Suppose it needed only one engineer Sprout wasn’t using on the core app. Does your call change — and what does that tell you about when an opportunity’s cost is high versus low? (Find the point where an option stops displacing the core bet and becomes spare capacity.)
Sequence the “not yet.” Sprout wins the core app in a year. Sketch the order it should revisit B and C, and say which one you’d reopen first and why — what makes one a better second move than the other from a position of strength.

11. Slides

Slide 1 — The focus trade-off

A 75-minute live-debate class on the strategic power of saying no — cutting a tempting option so the one bet that’s working can win.
Presenter note: say the honest line — this is teaching material, not a certification or credit.

Slide 2 — The situation: Sprout

Composite app: plans a week of family dinners, makes one shopping list. Parents love it.
One team of 8, ~10 months of runway, quietly running THREE bets at once.
A. Core app (40,000 families, growing) · B. Restaurant partnerships (famous chef, press, no revenue) · C. Corporate wellness (1 pilot, steady revenue, needs features they lack).
Presenter note: poll the room — “keep all three, or cut to one?” Mark the split.

Slide 3 — The focus trade-off

A small team has a fixed stock of people, time, and money.
So every “yes” to one thing is a silent “no” to another — there is no spare team hiding.
The only choice is whether you price the trade-off on purpose or let it happen by accident.

Slide 4 — Focus beats spreading thin

Spread a team of 8 across three bets: thin everywhere, strong nowhere — three near-misses.
Concentrate the same 8 on one bet: one thing that actually wins, and a win compounds.

Slide 5 — Opportunity cost — the price of a “yes”

The real cost of an option is the best thing you gave up to do it — not the cash it brings in.
The tempting option (press, a famous name, fast money) is often the highest-cost one.
“Exciting” and “real revenue” aren’t reasons to keep it — does it advance the bet you can win?

Slide 6 — Your call

Pick ONE bet to focus the whole team on: A, B, or C. The other two are cut to “not yet.”
Price the tempting one: what does Sprout give up if 5 people build restaurant features for 6 months?
Presenter note: every table commits to one letter before the debate.

Slide 7 — The defensible read

Focus on A, the core app — the only bet with real traction, and it fits Sprout’s strength.
Cut B (restaurants): exciting, but its true cost is the core app’s momentum.
Cut C (corporate wellness): plausible revenue, but drags a consumer team into unbuilt enterprise work.

Slide 8 — What each choice costs

Choosing B: spends the whole team on glamour while the paying, growing core goes cold.
Choosing C: trades a working product for a slow B2B build the team isn’t staffed for.
Choosing A: real cost too — walk away for now from the chef, press, and pilot — but one win beats three near-misses, and “not yet” keeps B and C open.
Presenter note: land the takeaway — the hardest, most valuable strategic move is a well-priced “no.”
