What is a white paper, and what is a case study?
A white paper is an authoritative report on a problem and a way of solving it. The form comes from government, where a white paper set out policy, and business borrowed it for the same reason: the name signals seriousness. A good one runs somewhere between six and twenty pages, makes an argument, backs it with research or original data, and is written for a reader who is trying to make a decision. It is thought leadership with homework.
A case study is a story about one customer. It describes the situation they were in, what was done and what changed, with numbers and a quote from the client. It can be a page, a short film or a slide, and it answers the question every buyer asks before anything else: has this worked for someone like me.
The two are usually written about together because they do complementary jobs. The white paper establishes that a company understands the problem; the case study proves it can solve it. For agencies the case study is the portfolio in prose, and the white paper is the point of view that makes the portfolio mean something.
Why it matters
Why white papers and case studies matter
Business buying is done by committees, and these are the documents that get forwarded. A case study travels from the person who found it to the person who signs, and it has to make the argument without anyone in the room to help. A white paper is how a company gets invited into a conversation before a brief exists, by being the one that explained the problem clearly.
They also work for search and for sales at the same time. A well-made white paper ranks for the questions a buyer types, collects the contact details of people who want it, and gives the sales team something to send that is not a brochure. A case study sits on the website, in the pitch deck and in the follow-up email. Both keep working long after they are published, which is more than most content can say.
In practice
How white papers and case studies work in practice
- 01
A white paper begins with a problem the buyer actually has, not a topic the company wants to talk about. Research follows, ideally with original data from a survey, a dataset or the company's own work, because a paper that only summarizes other papers has nothing to add. It is outlined, written plainly, edited hard and designed properly, with charts that explain rather than decorate. Then a decision about gating: trading the paper for an email address brings leads and costs readers. It is promoted like a product, through email, social, search and sales.
- 02
A case study starts with permission. The best time to ask a client is in the contract, before the work begins, because asking after a success is awkward and asking after a disappointment is impossible. Then an interview with the client, a structure of before, what was done and after, real numbers, a quote in the client's own words and sign-off on every sentence. It is published as a page, a PDF for sales and, increasingly, a short film, because a client saying it on camera is worth more than a paragraph saying it for them.
Watch out
What people get wrong about white papers and case studies
Writing a white paper that is a brochure in a serious font, so the reader learns what the company sells and nothing about the problem. Publishing a case study with no numbers, which is a testimonial wearing a suit. Forgetting to get permission, then discovering the best story cannot be told. Gating everything, so the content nobody has read is protected from the people who would have shared it. Writing for the company's own executives rather than for the buyer. And skipping design, when a document meant to signal seriousness looks like it was exported from a word processor at midnight.
