## Technique Sessions

### Five Whys - 10 minutes

**Description:** Deep exploration of the root problem by asking "why" five times to uncover core motivations.

**Ideas Generated:**

1. **Surface need:** Track reading progress to meet book club deadlines
2. **Level 2:** Avoid being late prevents spoilers and maintains enjoyment
3. **Level 3:** Full participation enables nice, interesting discussions
4. **Level 4:** Discussions expose user to books outside normal reading preferences
5. **Level 5 (Core):** Broadens horizons, encourages thinking differently, appreciates diverse perspectives

**Insights Discovered:**
- The app serves book club accountability first and foremost
- Spoiler avoidance is a key pain point
- User values being challenged with unfamiliar books
- Book club creates social/intellectual engagement
- Not catastrophic to miss deadline, but diminishes experience

**Notable Connections:**
- Core purpose is intellectual growth, but user wants to focus on **tactical features** only
- Don't over-engineer toward "learning" or "growth" features
- Keep it simple: track pages, meet deadlines, stay on pace

**User Decision:** Focus on tactical needs, not deeper philosophical features

## Component #1: Book Entry - DECIDED ✅

**Options Explored:**
- Manual entry (type title, author, pages)
- API lookup (Google Books, Open Library)
- Barcode/ISBN scan
- Import from Goodreads

**User Reference:** Obsidian Book Search Plugin workflow
- Simple search box (title/author/ISBN)
- API returns results with covers
- Click to select → auto-populates metadata
- Fast and easy (3 clicks)

**Decision Made:**
**Use Open Library API** - https://openlibrary.org/search.json

**Rationale:**
- ✅ No API key required (user preference)
- ✅ Completely free
- ✅ Good book data (title, author, pages, covers)
- ✅ Search by title, author, ISBN
- ✅ Decent rate limits for single-user personal use
- ✅ Can switch to Google Books API later if needed

**Implementation Notes:**
- Search box: user types book title or author
- Query Open Library API
- Display results with cover images
- User clicks to select
- Auto-fill: title, author, total page count
- User adds deadline date
- Book added to library

---

## Component #2: Daily Page Logging - DECIDED ✅

**Options Explored:**
- Manual text entry
- Number stepper/picker
- Quick log from book list
- Calendar-first entry
- Voice/scan entry
- Running total vs. daily snapshot

**Decision Made:**
**Quick Log from Book List**

**User Flow:**
1. Open app → See list of currently reading books
2. Tap book → "Log Progress" button appears
3. Pop-up: "What page are you on?" with number input
4. Enter page number → Save
5. Done!

**Implementation Notes:**
- Primary device: Phone (mobile-optimized UI)
- Backfilling: User can tap any past date on calendar to log retrospectively
- Timing tracking: Not needed - just capture page number, not timestamp
- Quick entry: Minimize taps - tap book, enter number, save (3 actions total)
- Allow backfilling for missed days

**Rationale:**
- ✅ Mobile-first design for quick daily logging
- ✅ Minimal friction (3 taps to log)
- ✅ Backfill capability for forgotten days
- ✅ No complex timestamp tracking needed

---

## Component #3: Progress Calculation - DECIDED ✅

**Options Explored:**
- Simple daily delta
- Pace-to-goal calculation
- Days remaining + pages remaining
- Ahead/behind indicator
- Projected finish date
- Multiple metrics dashboard

**Decision Made:**
**Pace-to-Goal Calculation**

**How It Works:**
1. System calculates: (Pages Remaining) ÷ (Days Remaining) = Required Pages/Day
2. Tracks your actual pace from recent logging history
3. Compares: Required vs. Actual pace

**Display Example:**
- "**Target:** 50 pages/day to finish on time"
- "**Your pace:** 45 pages/day (last 7 days)"
- Status indicator: On track / Slightly behind / Need to catch up

**Implementation Notes:**
- Recalculates every time you log progress
- Uses rolling 7-day average for "your pace" (smooths out weekend vs. weekday variance)
- Clear, actionable number: "You need to read X pages/day"
- Visual indicator if you're on track or falling behind

**Rationale:**
- ✅ Directly supports goal of meeting deadlines
- ✅ Actionable information (tells you what to do)
- ✅ Accounts for variance in reading patterns
- ✅ Adjusts dynamically as deadline approaches

---

## Component #4: Multi-Book Management - DECIDED ✅

**Options Explored:**
- Unified view (all books together)
- One book at a time focus
- Separate tracking per book
- Smart context switching
- Book status categories

**Decision Made:**
**One Book at a Time Focus**

**How It Works:**
1. **Primary Book** displayed prominently at top
   - Shows pace calculation, progress, deadline
   - Quick "Log Progress" button front and center
2. **Other Active Books** shown below (collapsed or minimal)
   - Tap to expand and see details
   - Tap "Make Primary" to switch focus
3. **Easy switching** when you want to focus on a different book

**Implementation Notes:**
- Typically tracking 1-3 books with deadlines simultaneously
- User is usually more absorbed in one "current" book
- Primary book gets the spotlight in UI
- Other books accessible but not distracting
- Simple tap to switch which book is primary

**Rationale:**
- ✅ Reduces cognitive load (focus on one book at a time)
- ✅ Matches user's reading pattern (absorbed in one main book)
- ✅ Still supports multi-book tracking
- ✅ Makes daily logging simple (usually logging the primary book)

---

## Component #5: Goal/Deadline Setting - DECIDED ✅

**Options Explored:**
- Deadline only
- Deadline + start date
- Flexible milestones
- "Days to read" input
- Auto-calculate from book club date

**Decision Made:**
**Deadline Only**

**How It Works:**
1. When adding a book, user sets: "Finish by [Date]"
2. System calculates required pages/day from today until deadline
3. Adjusts automatically each day as deadline gets closer

**Implementation Notes:**
- Simple date picker: "When do you need to finish this book?"
- System assumes "start date" = today (or first logged page)
- Deadline can be edited anytime (book club rescheduled, etc.)
- Recalculates pace whenever deadline changes

**Rationale:**
- ✅ Minimal input required
- ✅ Focus on the constraint that matters (deadline)
- ✅ Flexible - works whether you've started or not
- ✅ Simple UX - one date picker

---

## Component #6: Progress Visualization - DECIDED ✅

**Options Explored:**
- Simple progress bar
- Pace indicator gauge
- Calendar heat map
- Timeline view
- Minimal text-only
- Dashboard with multiple views

**Decision Made:**
**Minimal Text-Only with Green/Red Color Coding**

**Display Example:**
```
📖 The Name of the Wind

312 pages left, 18 days remaining
Target: 50 pages/day
Your pace: 45 pages/day (last 7 days)

[Color-coded status indicator]
🟢 On track
🟡 Slightly behind
🔴 Need to catch up
```

**Implementation Notes:**
- Clean text-based display
- Key numbers prominent: pages left, days left, required pace
- Color coding for quick status check:
  - **Green:** Your pace ≥ target pace
  - **Yellow:** Within 10% of target
  - **Red:** Falling behind (>10% below target)
- Mobile-friendly: easy to read, no chart rendering

**Rationale:**
- ✅ Fastest to understand at a glance
- ✅ Minimal screen space
- ✅ Clear, actionable information
- ✅ No unnecessary graphics
- ✅ Works great on mobile

   - Tap **today** → Quick log current page
   - Tap **future date** → View projected pace/milestones
   - Smart behavior based on date context

**Implementation Notes:**
- Calendar uses color intensity gradient (e.g., light blue → dark blue)
- Deadline dates have special marker (e.g., 🎯 or colored border)
- Single tap opens context-appropriate action
- Easy to backfill missed days or correct errors

**Rationale:**
- ✅ Quick visual scan of reading consistency
- ✅ Easy backfilling for missed days
- ✅ See deadlines in context
