Proposal One-Pager

Turns a rough idea into a one-page proposal: the problem, your solution, what it costs, and the ask.

What it does

You have an idea that would clearly work, and it has been sitting in your head for two months because turning it into something your boss can approve feels like a bigger job than the idea itself.

With this skill active, the assistant asks six short questions, including the one people always skip, which is what happens if nobody does anything. Then it works out what your reader is actually measured on. A director judged on cost reads a completely different page from one judged on risk, even when the facts are identical. It writes the problem in their unit, prices the thing honestly including the awkward ongoing bits, and marks every estimate as an estimate with the reasoning attached.

You get one page that ends in a single ask with a date on it, short enough that someone can say yes without booking a meeting to discuss it.

You end up with a one-page proposal ending in a single dated ask your decision-maker can approve without a meeting.

When to reach for it

Use it when you need a yes from someone who controls budget, headcount or the final call: a tool you want to buy, a hire, a pilot, a change to how the team works.

Skip it if you have no idea what the thing costs, even roughly. A proposal with no cost section reads as a wish and gets treated as one. Ask around for a rough number first, then come back.

description: Turns a rough idea into a one-page proposal a decision-maker can approve or reject without a meeting: the problem in their terms, the solution in plain words, the honest cost, the expected return, and one specific ask with a date. Use to pitch a project, a purchase, a hire, a pilot, or a change to whoever controls the budget.

# Proposal One-Pager

You write the page that gets a decision. Not the page that explains the idea well, and not the page that wins an argument. The test is whether someone who was not in your head can say yes, no, or "tell me one more thing" without scheduling anything.

## Workflow

The order matters. Writing the solution before you know the reader produces a page about your idea rather than about their problem.

1. **Take the six inputs.** Ask for them together, not one at a time.
2. **Name the decision-maker and their currency.** Money, time, risk, growth, or reputation. Pick one.
3. **Write the problem in their terms,** with a cost attached.
4. **Write the solution as the obvious next move,** in plain words.
5. **Cost it honestly,** including the parts that are inconvenient.
6. **State the expected return,** marking every estimate as one.
7. **Write one ask, with a date.**
8. **Cut to one page.** Trim detail, never sections.

```text
Proposal checklist
[ ] Six inputs collected: idea, problem, who feels it, reader, cost, ask
[ ] Reader's currency identified and the page written in it
[ ] Problem has a number or a named consequence attached
[ ] Solution stated in one plain sentence before any detail
[ ] Cost includes money, time, and the ongoing burden after launch
[ ] Every estimate labelled as an estimate with its basis
[ ] One risk stated honestly in one line
[ ] The ask is a single decision with a date
[ ] Fits on one page
```

## Step 1: the six inputs

Ask for all six in one message:

- **The idea,** in their own words. Rough is fine.
- **The problem it solves,** and who currently feels it.
- **The reader:** who approves this, and what they are measured on.
- **What it costs:** money, hours, people, in rough numbers.
- **What they are asking for:** approval, budget, a pilot, a decision by a date.
- **What happens if nobody does anything.** This is the one people forget, and it is usually the strongest paragraph on the page.

If cost figures are missing, ask for a rough estimate rather than proceeding without one. A proposal with no cost is a wish, and readers treat it as one.

## Step 2: the reader's currency

Every decision-maker converts your proposal into one unit before they judge it. Find out which.

| Currency | What the problem paragraph should lead with |
|---|---|
| Money | The amount being lost or spent now, per month or per year |
| Time | Hours going somewhere they should not, and whose hours |
| Risk | What breaks, who finds out, and how bad the day is |
| Growth | The deals, users or capacity the current situation is blocking |
| Reputation | What a customer, regulator or candidate currently sees |

Writing a time-saving proposal for a risk-focused reader is the most common way a good idea fails. Same facts, wrong unit.

If the user does not know which, ask what their reader complained about most recently. That is the currency.

## Step 3: the problem paragraph

Two to three sentences, and the hardest part of the page. It must contain:

1. **What is wrong,** stated as a fact rather than a feeling.
2. **A cost,** in the reader's currency, with a number if one exists.
3. **The trend or the trigger** if there is one, because a problem that is getting worse is a different decision from one that is stable.

> We lose about three hours a week arranging meetings by email. Across the six of us that is roughly 150 hours a year, and it has grown since we added the two contractors.

Do not open with the idea. A reader who has not felt the problem will read the solution as a preference.

Do not exaggerate. One inflated number found is enough to make a reader distrust the whole page, including the accurate parts.

## Step 4: the solution

Two to four sentences. The first one must be a complete answer on its own, because some readers will read only that.

> Buy a shared scheduling tool that lets people book directly against our calendars.

Then the detail that makes it real: what changes, who does the work, how long it takes to be running. Plain nouns, no product-marketing vocabulary, no phrases the reader would have to look up.

Alternatives considered belong here in one line, if there are obvious ones: "We tried a shared calendar block in March; it failed because external people cannot see it." This closes off the reader's first objection before they raise it.

## Step 5: costing it honestly

Three parts, and the third is the one people leave out:

- **Money.** The price, stated as it will appear on an invoice. Monthly and annual if it recurs.
- **Effort to set up.** Whose hours, roughly how many.
- **The ongoing burden.** Who maintains it, who administers it, what happens when the person who set it up leaves.

Hidden costs surface later and cost more than the money did. A proposal that names its own inconvenient parts reads as trustworthy, and trustworthy is what gets a yes.

State one genuine risk in a single line. Not a fake risk you can immediately dismiss. A real one, with what you would do about it.

## Step 6: the return

What the reader gets. Real numbers where they exist, and every estimate labelled with its basis:

> Estimated 100 hours a year returned to the team. Based on the three hours a week we currently spend, assuming the tool removes two of them.

Never present an estimate as a measurement. "Saves 150 hours" and "estimated 100 hours, based on X" are read completely differently, and the second one survives scrutiny.

If the return is not quantifiable, say so and describe what changes concretely instead. "Customers stop receiving two different answers from two people" is a real benefit without a number attached.

## Step 7: the ask

One decision, one date, one named person.

- Works: "Approve a one-month trial at £40 a month. I will report time saved on 30 April."
- Fails: "Support this initiative." "Let me know your thoughts." "Approve budget for tooling."

The ask should be the smallest thing that lets the work start. A pilot is easier to approve than a rollout, and a pilot that reports back on a date is easier still, because it gives the reader a second decision point rather than a commitment.

## The page

```text
[Title: the idea in one plain line]

The problem
[2-3 sentences. What is wrong, what it costs, whether it is growing.]

What I propose
[2-4 sentences. The solution in the first one. Alternatives ruled out, if any.]

What it costs
- Money: [amount, and whether it recurs]
- Setup: [whose hours, how many]
- Ongoing: [who owns it afterwards]
- Risk: [one real one, and what you would do]

What we get
[The return. Estimates labelled as estimates, with their basis.]

The ask
[One decision, one date, one person.]
```

## Example

**Situation:** a six-person team wants a scheduling tool. Reader is an operations director measured on cost per head.

> **A shared scheduling tool for the support team**
>
> **The problem.** We lose about three hours a week arranging meetings by email, mostly with external customers who cannot see our calendars. Across six people that is roughly 150 hours a year. It has got worse since the two contractors joined in March, because they are in a different time zone.
>
> **What I propose.** Buy a shared scheduling tool so customers book directly against our real availability. Setup is one afternoon and the calendars we already use stay as they are. We tried blocking time in a shared calendar in March; it failed because external people cannot see it.
>
> **What it costs.**
> - Money: £40 a month for six seats, £480 a year.
> - Setup: one afternoon of my time.
> - Ongoing: I own the account. If I leave, it transfers with the team inbox.
> - Risk: customers may book badly timed slots. We can set booking rules, and I would rather fix that than keep the email back-and-forth.
>
> **What we get.** Estimated 100 hours a year returned to the team, based on removing two of the three hours we currently spend each week. At our loaded rate that is worth roughly £3,000 against a £480 cost.
>
> **The ask.** Approve a one-month trial at £40. I will report actual hours saved on 30 April, and cancel it myself if the number is not there.

Note what the page does: it leads with the reader's currency, it names the failed previous attempt before the reader can, it labels the 100 hours as an estimate with a basis, it states a risk the author cannot dismiss, and it asks for a trial rather than a commitment.

## Rules

- One page. If it runs long, cut detail, never a section. A proposal missing its cost section reads as a proposal hiding its cost.
- Never invent a number. Every estimate is labelled, with the assumption it rests on.
- State one real risk. A page with no downside reads as a sales pitch.
- Plain words only. No "synergy", no "drives value", no "strategic enabler". If the reader would not use the word, do not use it.
- The ask must be specific and doable this week.
- Do not bury the cost. A reader who has to hunt for it assumes it is bad.
- Write in the reader's currency even when yours is different.

## Edge cases

- **The user has no numbers at all.** Do not proceed silently. Ask for the roughest possible estimate, label it clearly as rough, and say what would firm it up. "Roughly three hours a week, from asking the team" is honest and usable.
- **The real cost is political,** not financial. Someone loses territory, or a team's process changes. Name it in one line, because the reader already knows and will trust the page more for it.
- **The idea is not ready.** The problem is real but the solution is a guess. Change the ask to the smallest investigative step: two weeks to scope it, a conversation with two customers.
- **The reader has already said no once.** Lead with what has changed since. If nothing has changed, say so plainly and consider whether the page is worth sending.
- **Multiple decision-makers with different currencies.** Write for the one who can say no. Add a line for the others rather than averaging the whole page into something aimed at nobody.
- **The proposal competes with something the reader owns.** Say so directly and early. Discovering it themselves halfway down is far worse.
- **The user wants to include a slide deck's worth of detail.** Put the extra in an appendix that is clearly optional, and keep the page complete without it.
