Summary of "260504_기획_01"
Main ideas / concepts covered
1) Where the video/project work stands (schedule & deliverables)
- The speaker is tracking progress on a website/business project and deciding where to place lecture materials (education section vs later).
- They describe a pipeline: data research → site building → data analysis:
- Early stages: business fundamentals + data research (“planting”)
- Middle: build/maintain the site (maintenance materials; SQL/data extraction basics appear earlier)
- Later: decision-making driven by analytics/data analysis (e.g., Google Analytics)
- Next-week plan:
- Competitor/market research continues
- Wednesday: session on Unit Economics
- Figma work progresses in parallel
- Afternoons: practical training after lunch
- After the site is set up, they plan to:
- Build an analysis document
- Write and organize the remaining materials
2) Data/analytics foundation: using GA4 + defining metrics
- Analytics is presented as something that becomes meaningful only after the site is built.
- GA4 menus/features may change frequently (e.g., privacy changes, UI/menu updates), so templates may not always match the current interface exactly.
3) Unit Economics as the core business model logic (CAC, LTV, ARPU, churn, etc.)
The lecture focuses on how to evaluate business health through the relationship between acquisition cost and customer value.
Key terms and relationships
- CAC / CC (Customer Acquisition Cost)
- The marketing + sales spend needed to acquire customers.
- Includes (broadly): advertising, marketing labor, promotions/coupons, and content production costs.
- LTV (Customer Lifetime Value)
- Total customer value generated over time (revenue/profit framework).
- Gross margin / growth margin
- Revenue minus cost of goods sold; used as the “profit basis” for LTV.
- Payback / “Fairlead” (payback period)
- How long it takes to recover acquisition costs.
- Core health indicator idea
- LTV should exceed CAC (or at least remain favorable based on the ratio logic they discuss).
- If the ratio is too low or LTV is not high enough, it indicates a problematic unit economics structure.
Conceptual calculation flow (as described)
- Model the business value per customer as:
- Value created by one customer (LTV side)
- Cost incurred to acquire one customer (CAC side)
- The structure often includes:
- Period-based calculations (often monthly)
- Churn/dropout rate to model customer lifetime
- ARPU (average revenue per user per month)
- LTV is constructed from:
- Monthly value (from ARPU / profit basis)
- Churn behavior across months
- Time horizon (e.g., 6 months vs 12 months)
- Growth margin (profit margin basis) is applied before projecting lifetime value.
4) Why retention matters: funnels, churn, conversion rate, and optimization targets
- Analytics is tied directly to funnels and retention:
- Funnel analysis (“coat analysis”) identifies where users drop off.
- A/B testing validates whether changes improve conversion.
- The speaker suggests UI/UX complexity as a common reason for dropout (including a shopping cart analogy).
- They emphasize “planting events” and measuring behavior points:
- Where to track events in GA4 to link behavior to revenue structure:
- acquisition vs activation vs purchase vs dropout
- Where to track events in GA4 to link behavior to revenue structure:
5) Research & hypothesis methodology (qual + quant) and validation
A structured approach to product research and experimentation.
Research planning steps (high-level)
- Design research
- Define the problem and identify what information is required
- Complete questionnaires / explanation sheets with the needed details
- Formulate hypotheses
- Set OKRs and KPIs (explicitly mentioned)
- Run research in stages:
- Competitor analysis + quantitative/qualitative research
- Interviews (qualitative): sincerity method referenced; IDI/FGI-like terminology appears
- Surveys/questionnaires (quantitative): e.g., Google Forms vs Notion
- Behavioral artifacts: persona, user journey, diaries/daily records (as examples)
Hypothesis structure and verification requirement
- A hypothesis must be:
- Specific (clear description)
- Verifiable (measurable result)
- Testable under conditions using “if… then… because…” logic
- The speaker warns against unverifiable assumptions—if it can’t be measured/verified, it shouldn’t be treated as a hypothesis.
- Testing is connected to:
- Finding problems from qualitative research
- Measuring improvement impacts with quantitative analysis (GA4, A/B tests, etc.)
Validation approach using data/tools
- Funnel analysis for dropout and conversion points
- A/B testing for causal validation
- User testing / MVP prototype testing
- Criteria such as UX inspection and “usefulness” turning points
6) Priority management: IC framework + impact/confidence/ease scoring
Hypotheses/features are ranked using an ICE-style prioritization approach.
Detailed bullet process (as implied)
- For each hypothesis, compute:
- Impact (expected effect magnitude; often 1–10)
- Confidence (how sure you are; 1–10)
- Ease (Effort/Ease of implementation; 1–10, where lower effort is “easier”)
- Compute a priority score via an ICE-style arithmetic approach:
- High impact + high confidence + high ease → higher priority
- Then rank and decide what to do first:
- Strong emphasis on consistently applying the framework to pick early actions
- Practical loop: implement → observe results → pivot if needed
- Notes mention that lower confidence/high risk may affect ordering to reduce uncertainty, but the main takeaway is framework-driven prioritization
7) Agile execution loop (short sprints, quick direction changes)
- Work is split into short sprints (e.g., a few days).
- Direction can change based on research outcomes.
- Implement the “front part” first, then refine through feedback.
- The core message: frequent iteration to handle fast-moving requirements.
8) Web design & development workflow in practice (HTML/CSS + Figma + Parallax)
The later part becomes a hands-on tutorial covering layout design and implementing parallax.
Key UI/layout terminology taught
- Standard layout types:
- Standard
- Responsive
- Card
- Grid
- One-page / full page
- HTML section structure:
- header, main content, footer
- Hero section (common in landing pages)
- CTA section (concept mentioned)
- Naming conventions:
- camelCase for class naming
- Template-driven “future modules” / UI component references
Responsive vs full page behavior
- Viewport units are referenced for full-screen layouts:
- 100vw / 100vh
- Mobile behavior differs:
- Parallax and scroll interactions often require manual handling/tuning on mobile.
Parallax implementation concepts
- Split images into multiple layers (After Effects / Photoshop-style slicing).
- Parallax motion is driven by:
- scroll position
- mouse position (mouse-move parallax)
- sometimes direction and percentage values (e.g., “50%” can mean half of total scroll length rather than half of viewport)
- A loading screen approach is mentioned:
- wait until images load, then show a “Please…” message/loading animation
Figma workflow taught (practical steps)
- Start from a draft file and use templates/material kits.
- Use frames and set device sizes (e.g., 1440 → 1024 shown).
- Use guides/grids:
- columns/gutter concepts
- reminder to view at 100% (Control + 0)
- Build consistent layout structure:
- header, hero, visual area, content, footer areas
- Translate the Figma design into HTML/CSS afterward.
