When to open: When you need to conduct competitive analysis / market research / industry research / due diligence before entering a new track. This wiki integrates the yitang Truman + Zhang Lei OSCAR system + Wang Kai's practical experience + Wang Huiwen's tier framework.

One-sentence core:Truman: "If there is only one ability that is 100% actionable and can earn back 10 years of tuition, it is systematic research". OSCAR five-step framework + 5 major channels for exploration + 60-75-85 three tiers = upgrade research from "searching Baidu and copying templates" to "scientifically obtaining information to support decision-making".

0. OSCAR Research Model (led by yitang and Zhang Lei)

Yitang / Complete system of intelligence research + lean experimentation Part A:

O S C A R
Objective(Objective) Scope(Scope) Channel(Channel) Analyze(Analyze) Report(Report)

Zhang Lei(Yitang partner / MBA lead): "The value of systematic research — helps you obtain high-value information and make high-quality decisions. "

Zhang Lei reviews 5-10 projects every day, and has advised a 2-billion-yuan payment company / a daily chemical overseas expansion company that raised 25 million yuan in financing.


1. Cross-author consensus (4 points)

1.1 Research is the ability most lacking among 95% of operators

Yitang / Complete system of intelligence research + lean experimentation §1:95% of operators lack research capabilities:

  • Lack of awareness
  • Lack of methodology
  • Lack of research skills

Real cases after learning:

  • One student directly falsified the hypothesis and abandoned the startup project
  • One student found that the marketing director did not understand the market and fired them directly
  • One student halted heavy R&D investment, comprehensively researched competitors' technology roadmaps, and obtained the answer

1.2 5 major research channels (exploratory arsenal)

Channel Purpose
Public information(reports / financial reports / news / Zhihu) Mandatory check for beginners
Service acquisition(consulting firms / Zaihang / paid interviews) In-depth information
Product teardown(competitor products / services / processes) Operational details
User connection(user interviews / customer service / reviews) Real feedback
Fake recruitment(fake interviews / resume pool) Internal information

1.3 60-75-85 point research tiers

Yitang / Advanced business prediction (industry canvas + concentration + cases) §3:

Tier Capability Training objective
60 points Able to research the present Obtain current track competition concentration data
75 points Able to predict the endgame Form insights and predict future concentration levels
85 points Able to formulate strategies Determine operational strategies based on concentration change trends

1.4 Using AI as a ruler (validated by Wang Kai)

Wang Kai RSI investment practical case collection + AI value investing philosophy —— Using research as a ruler:

  • Give AI a stable framework → research results become quantifiable
  • Running the same company multiple times should yield similar results
  • Scenarios requiring data accuracy must go through MCP / API,do not use AI web search

2. Detailed explanation of the OSCAR five-step framework

2.1 O - Objective

  • Why do the research? What are the core 1-3 hypotheses to be verified?
  • Avoid: doing research for the sake of doing research

2.2 S - Scope

  • Define: industry / sub-track / time period / company tier (head/waist/long tail) / geography
  • Avoid: scope too large, report looks good but is unusable; scope too small, key information is missed

2.3 C - Channel (5 major channels)

  • Public / services / product teardown / user connection / fake recruitment

2.4 A - Analyze

  • 3 reliability strategies for the A step: quantitative anchoring + primary source deep dive + cross-validation
  • Key rollback action: Pause before A and ask yourself "is this enough to support judgment"

2.5 R - Report

  • If unsatisfactory, roll back to supplement A for multiple rounds
  • 5-cell template + decision recommendations

3. Excellent Research Hacker cases (exclusive)

Yitang / Complete system of intelligence research + lean experimentation candy:

3.1 5 complete cases

Case Key actions
Study room V1→V4 progression 4 rounds of research gradually increasing precision
Zhang Lei nursing home 4-round onion peeling 800 yuan Zaihang verification + 5 nursing homes 5-sheet empirical study
Self-service yogurt machine: rummaging through trash cans to collect receipts Primary data
Anime e-commerce warehouse visits 7+ visits including Xiaomi and Japan's Surugaya
Luckin Coffee Snow Lake Capital perfect score case 92 full-time staff + 1418 part-time staff + 25843 receipts + 11260 hours of video, 4 methods to calculate order volume

3.2 3 counterexamples

  • Yu'an marathon poster
  • Student Chen Pepper Lunch iron plate steak
  • Student Zhang breakfast maker

3.3 Differentiation of 3 types of interview methods

Type Usage
Expert interview Industry landscape / key judgments / trends
User interview Real needs / pain points / substitutes
Franchisee / customer interview Actual operating data / real profits

4. Wang Huiwen concentration CRn research

Yitang / Advanced business prediction (industry canvas + concentration + cases) §2:

3 endgame forms:

Form CR5 threshold Example
Highly concentrated CR5 ≥ 90% WeChat, Meituan, Didi
Relatively concentrated CR5 ≈ 50% High-end baijiu, large home appliances, mobile phones
Relatively fragmented CR5 < 30% Beauty, catering, women's clothing, women's shoes

3 methods to research concentration:

  1. Read prospectuses / financial reports(when there are leading listed companies)
  2. Read research reports(keyword: XX industry + concentration)
  3. Conduct your own research and estimation(list leading players → research revenue → estimate market share)

5. How to choose — research paths by identity

Who you are Primary method Starting point
Want to do competitive analysis OSCAR five-step framework O Objective → S Scope → C 5 channels → A Analyze → R Report
Want to do industry research 60-75-85 tiers Present → endgame → strategy
Investment / rigorous scenarios Wang Kai AI as ruler + MCP Data goes through MCP, not AI web search
Deciding whether to franchise a brand Zhang Lei 4-round onion peeling 8 types of information sources + 800 yuan Zaihang verification
Learning classic cases Excellent Research Hacker assignments Study room / nursing home / Luckin / anime e-commerce

General discipline:

  1. If you only learn one ability, it is systematic research(Truman)
  2. OSCAR steps cannot be skipped(milestone-based logic)
  3. 2 rollback actions(before A / if R is unsatisfactory)
  4. 3 reliability strategies(quantitative anchoring + primary source deep dive + cross-validation)
  5. Failed projects are the most valuable textbooks
