Document terms, in plain English

A pitch deck is a focused set of slides that walks an audience through a business or idea: the problem it addresses, the proposed solution, the market, the business model and the team behind it. It is meant to be delivered out loud or sent ahead of a meeting, so it favours clear headlines and visuals over dense paragraphs.

A good pitch deck tells a coherent story and earns attention quickly, usually in roughly ten to fifteen slides. It states a single clear message per slide, backs claims with a few concrete numbers rather than many, and leaves the detailed financials and appendices for follow-up materials.

An investor deck is a type of pitch deck aimed at one audience: people deciding whether to invest. While a general pitch deck might sell a product to a customer or introduce a company to a partner, an investor deck is built around the case for backing the business, its market size, traction, unit economics, fundraising ask and how the money will be used.

The difference from a broader pitch deck is emphasis rather than format. A good investor deck still tells a clear story, but it leans harder on evidence: a credible market estimate, real traction figures, a believable financial trajectory and a specific ask. It typically runs ten to twenty slides, with deeper financial detail kept in an appendix or a separate data room.

A one-pager condenses the essentials of something, a company, a product, an investment opportunity, a project, onto a single page. It is used when an audience needs to grasp the core idea fast: as a leave-behind after a meeting, an email attachment, or a quick reference that sits alongside a longer document.

A good one-pager is ruthlessly selective. It states what the thing is, why it matters and what the reader should do next, using short sections, a clear hierarchy and perhaps a single chart or image. Because the space is fixed, the discipline is deciding what to leave out rather than how much to add.

An executive summary opens a longer report, business plan or proposal and distils it for a busy reader, typically a decision-maker. It covers the purpose, the main findings or argument, and the recommendation or request, so the reader can act on it even if they never reach the detailed sections that follow.

A good executive summary can stand on its own and is written after the main document, not before, so it reflects what the work actually says. It usually runs from a few paragraphs to a page or two, mirrors the order of the full document, and states conclusions plainly rather than teasing them.

A sales deck is the presentation a seller uses to move a prospect toward a purchase. Unlike a pitch deck aimed at investors, it centres on the buyer: the problem they face, how the product solves it, what results they can expect, proof from similar customers, and pricing or next steps.

A good sales deck is framed around the customer rather than the seller. It leads with the buyer's situation, uses concrete proof such as case studies, metrics or testimonials, and keeps the slide count tight so the conversation, not the slides, carries the meeting. Detailed specifications are usually left to follow-up materials.

A slide deck is the file, the collection of individual slides, produced in tools such as PowerPoint, Keynote or Google Slides. The word 'presentation' is often used as a synonym, but strictly speaking the presentation is the act of presenting while the deck is the document that supports it; a deck can also be read on its own, with no one presenting.

A good slide deck keeps each slide to one idea and lets visuals do work that prose would do in a written document. Length depends entirely on the setting, from a handful of slides for a quick update to dozens for a detailed review, but the consistent mark of quality is restraint: enough on each slide to follow, not so much that it becomes a script.

A business proposal is sent by one party to another to win work or agreement. It typically describes the client's need, the proposed solution, the scope of what will be delivered, the timeline, the price and the terms. Proposals can be solicited, written in response to a formal request, or unsolicited, sent proactively to start a conversation.

A good business proposal is specific to the recipient rather than a generic brochure. It shows a clear understanding of the client's problem, ties every deliverable to that need, and makes the cost and next steps unambiguous. Length ranges from a page or two for a simple engagement to a detailed document for a large contract.

A white paper is a longer-form document that examines a problem and presents a reasoned case or solution, backed by research, data and analysis. The form began in government and policy and is now common in business and technology, where it is often used to explain a complex approach and build credibility with a professional audience.

A good white paper is grounded and educational rather than promotional: it argues from evidence, cites its sources, and stays useful even to a sceptical reader. White papers typically run from a few pages to twenty or more, with a clear structure of introduction, analysis and conclusion.

In business and marketing, a case study tells the story of a specific customer or project: the situation they started in, the challenge they faced, the action taken, and the outcome. It works as evidence, letting prospective buyers see a credible, concrete example instead of relying on general claims.

A good case study is honest and specific. It names the situation clearly, describes what was actually done, and supports the result with real numbers wherever possible. The strongest ones follow a simple arc, challenge, solution, result, and let the customer's own words and measurable outcomes do the persuading.

A résumé presents a candidate's professional background, roles held, achievements, skills and qualifications, so an employer can assess their fit quickly. In American usage a 'résumé' is typically a concise one- to two-page summary, while 'CV' (curriculum vitae) can mean the same short document or, in academic and many international contexts, a longer and more complete record.

A good résumé is clear, well-organised and tailored to the role, leading with the most relevant and recent experience. It favours specific accomplishments over generic duties, often quantifying results, and stays easy to scan, since recruiters typically read it in seconds before deciding whether to look closer.

A cover letter accompanies a job application and does what a résumé cannot: it speaks directly to the reader, connecting the candidate's experience to the specific role and showing genuine interest in the organisation. Where the résumé lists what someone has done, the cover letter explains why it matters here.

A good cover letter is brief, usually three or four short paragraphs on a single page, and clearly addressed to the role and, where possible, the person reading it. It picks out a few of the most relevant strengths rather than restating the résumé, and reads as a natural, confident note rather than a template.

A business report gathers facts, data or research on a defined subject and organises it for a particular audience and purpose, for example a performance review, a market analysis, a project update or a recommendation. It is usually structured, moving from an overview through the detail to conclusions, so a reader can follow the reasoning or jump to the part they need.

A good report is clear about its purpose and audience, separates evidence from interpretation, and supports its conclusions with data. Many open with an executive summary and use headings, tables and charts so the findings are easy to navigate. Length ranges from a short internal memo to a substantial formal document, depending on the subject.
