How to get up to speed in a new industry in 30 days
Spend the first week on vocabulary and a map of how money flows through the industry. Spend the second on the biggest companies, using their annual reports and earnings calls. Use the third for regulation, trade press, and the open debates, and the fourth for conversations with people who work in it. Write a two-page brief at the end and test it on someone who knows the field.
This works whether you are starting a new job, joining a consulting project, selling into a sector, or researching it as an investor. The order stays the same; the emphasis changes.
Why a plan beats reading everything
A new industry arrives as a flood of acronyms, company names, and news. Reading at random leaves you with facts but no structure to hang them on. The plan below builds the structure first, then fills it. Each week ends with something you can show: a glossary, a map, a list of players, a brief.
The time estimates are rough. They assume about an hour a day on top of your normal work.
The 30-day plan
Week 1 (days 1 to 7): Learn the vocabulary and draw the value chain
Build a glossary. Every industry has dozens of terms that insiders use without explaining. Keep a running list. Write each definition in your own words, with one example. If you cannot give an example, you do not understand the term yet.
Draw the value chain. On one page, sketch who supplies inputs, who makes or delivers the product, who sells it, who uses it, and who pays. In many industries the user and the payer are different, as with health care, advertising, or enterprise software. Mark where the money flows and where the margins seem highest.
Test it with the five forces. Michael Porter's framework, restated in his 2008 Harvard Business Review article, names the forces that shape an industry's profits: rivalry among existing competitors, the power of suppliers, the power of customers, the threat of new entrants, and the threat of substitutes. Porter's summary also makes two points that save beginners from easy mistakes: a fast-growing industry is not always a profitable one, and government policy can change the strength of each force.
Get the numbers. For US industries, the Bureau of Labor Statistics' Industries at a Glance gives a "snapshot" of national data for over 100 industries, drawn from different BLS surveys. It is a quick way to see the size and shape of employment in a sector.
Week 2 (days 8 to 14): Learn the key players from their own filings
Pick the three to five largest public companies in the space, plus one fast-growing challenger.
Read their annual reports. In the US, most public companies file a Form 10-K each year with the SEC. The SEC's guide to reading a 10-K calls Item 1, "Business," "a good place to start to understand how the company operates." It can cover products, markets, competition, regulation, and seasonal factors. Item 1A, "Risk Factors," lists the most significant risks, which companies generally order by importance. Some risks are industry-wide, and those are exactly what you want to learn. Item 7, management's discussion and analysis, gives the company's own view of its results and what drives them.
Filings are free. EDGAR, the SEC's filing system, offers "free public access to millions of informational documents." Its full-text search covers filings since 2001, so you can search a term, such as a regulation name or a competitor, across every company that mentions it.
Listen to one earnings call per company. Look on the company's investor relations page for the call recording, slides, or transcript. Read the analysts' questions closely. They show what people who follow the sector full-time worry about.
Make a player table. For each company: what it sells, to whom, how it makes money, its main risk, and how it describes its competitors.
Week 3 (days 15 to 21): Regulation, trade press, and the open debates
Find the regulators. Item 1 of the 10-K often names the rules that apply. Write down each regulator, what it controls (pricing, safety, licensing, data, competition), and the rule changes people are arguing about now.
Pick your trade press. Ask two or three people in the industry which newsletters, publications, and podcasts they actually read. Subscribe to those, not to the first search result. Skim headlines daily; read one long piece a day.
List the open debates. Every industry has three to five questions that insiders disagree on: a new technology, a pricing model, a pending rule. For each, write down both sides and who holds them. It shows you which questions do not have settled answers, so you do not repeat one side as fact.
Check event agendas. The session titles at the main trade conference tell you what the industry thinks is important this year.
Week 4 (days 22 to 30): Talk to experts, then write it down
Interview five to eight people across the value chain: a customer, a supplier, a salesperson, someone at a competitor if that is appropriate, and a veteran who has seen a cycle or two. Ask the same core questions each time:
- What do newcomers always get wrong about this industry?
- Where does the money really get made?
- What changed in the last three years, and what will change next?
- Who should I read or follow?
Write a two-page brief. Cover the value chain, the key players, how money is made, the regulation, the open debates, and what you still do not know. Then ask one expert to mark it up. Their corrections are often the most useful part of the month.
How to adapt the plan to your goal
| Your goal | Spend extra time on |
|---|---|
| New job | Your employer's position in the value chain, and the vocabulary your team uses daily |
| Consulting project | The five forces, the player table, and the client's top risks from its own filings |
| Sales | Who pays and who decides, the customer's pressures, and the regulation that drives purchases |
| Investing in a sector | Risk factors, margins across the value chain, and the open debates |
Where Gregator fits in the first week
Gregator is our product, and it fits day one, when you do not yet know which questions to ask. Type a topic such as "How the US medical device industry works: value chain, reimbursement, regulation, and key players", and it researches the open web and builds a course of 1 to 12 Chapters, with inline footnotes and a Sources list in each one and a trust overview that shows the mix of source types behind the course. Ask Greg, the chat tutor, about a term for your glossary that you did not follow, and accept a deep dive when Greg offers one, which adds a Chapter on one part, such as the approval process. Gregator does not read your company's internal documents or files you upload, and it is English-first, so check key numbers against the filings and the people you interview. If you onboard a team, anyone can read a public course link without an account.
Frequently asked questions
How long does it take to learn a new industry?
You can get a working map in about 30 days at an hour a day. Real fluency, the kind that lets you spot what is new and what is noise, takes longer. Think months, and it comes mostly from conversations and work.
What should I read first when entering a new industry?
Start with an overview that explains the vocabulary and value chain, then the 10-K of the largest public company in the sector. The SEC's guide says Item 1, "Business," is a good place to start.
How do I find experts to talk to in a new industry?
Start with colleagues and their contacts, then former employees of key companies, then authors of articles you found useful. Keep requests short and specific, and offer something in return, such as your brief.
What if the industry has no public companies?
Look for public companies that supply it or buy from it. Their 10-Ks often describe the sector in their Business and Risk Factors sections. Trade associations, government statistics, and expert conversations then carry more of the weight.
