# Macroplan — Design (QFD)

Goal-driven design for the Macroplan app: a week-granular, learning-oriented view of committed Features rendered as an interactive web view from a source file. This document covers *what the system must do and what we build*; the vocabulary lives in [CONTEXT.md](CONTEXT.md) and the original-estimate baseline decision in [ADR-0001](docs/adr/0001-original-estimate-as-baseline.md). It is not a spec or a task list.

Strength weights used in matrices: **9** strong, **3** medium, **1** weak, blank none.

## 1. Goals — the WHATs

| ID  | Goal                                                                          | Weight | Source                          |
|-----|-------------------------------------------------------------------------------|:------:|---------------------------------|
| G1  | See at a glance where every Feature stands against its Original Estimate — the honest record | 10 | brief + [CONTEXT.md](CONTEXT.md) |
| G2  | Turn estimation misses into captured Learnings for next time                  |   8    | brief + [CONTEXT.md](CONTEXT.md) |
| G4  | Author & update the whole plan fast during a weekly review                    |   8    | brief                           |
| G3  | Know whether external Milestones are at risk                                  |   7    | brief + [CONTEXT.md](CONTEXT.md) |
| G5  | Hand stakeholders a shareable read-only view                                  |   5    | brief                           |

## 2. Functions — the HOWs

| ID  | Function                                                              | Dir | Target (now)                                                                                          |
|-----|----------------------------------------------------------------------|:---:|-------------------------------------------------------------------------------------------------------|
| F1  | Render the plan legibly — bars, symbols, status colors, now-line, hover comments | → | reader IDs any Feature's state (on-time/late/overdue/slip-count) in ≤3s; Feature name + week axis never lost even when the plan exceeds the viewport |
| F2  | Classify each Delivery on-time/late against the Original Estimate     |  →  | 100% correct per ADR-0001; markers land on the right Week                                             |
| F3  | Reflect a source edit in the rendered view                           |  ↓  | ≤1s (live reload while authoring)                                                                     |
| F4  | Add / edit / remove a Feature with a single local edit               |  ↓  | one contiguous block per op; no ripple edits — Weeks auto-layout, Milestones reference Features by name |
| F5  | Make it easy to attach an optional Learning to a delivered Feature   |  ↓  | one optional field; rendered in the trailing column when present, blank otherwise                     |
| F6  | Render a Milestone and flag its unmet required Features              |  →  | vertical line at the correct Week; unmet required Features identifiable                                |
| F7  | Export the rendered plan as a shareable image (clipboard + download) |  →  | one click → PNG on clipboard and/or downloaded; fully client-side, no backend                         |

## 3. Cascade — Goals → Functions → How → Components

- **G1** See where every Feature stands vs. its Original Estimate — the honest record  _W:10_
  - **F1** Render the plan legibly (incl. at scale)  _Dir→ reader IDs a state ≤3s; name + axis never lost_
    - **How**: DOM rendering with CSS Grid (symbols are the visual vocabulary *inside* cells; layout is real DOM) — chosen over a preformatted monospace text block, which can't pin a column on scroll. See T1.
      - **Component**: **C3 Grid renderer** — bars (`┣━`), markers (`◯△◉▲`), status colors, Now line, sticky name column + sticky week-header row, hover tooltips for status notes
- **G2** Turn estimation misses into captured Learnings  _W:8_
  - **F5** Make it easy to attach an optional Learning to a delivered Feature  _Dir↓ one optional field_
    - **How**: a single optional `learning` field on a Feature block; rendered in a persistent trailing column when present
      - **Component**: C3 (trailing Learning column), C1 (TOML field)
- **G4** Author & update the whole plan fast during a weekly review  _W:8_
  - **F4** Add / edit / remove a Feature with a single local edit  _Dir↓ one block per op, no ripple_
    - **How**: TOML `[[feature]]` / `[[milestone]]` blocks keyed by date literals; renderer derives Weeks & marker placement so edits never ripple. See T2.
      - **Component**: **C1 TOML source + parser** (smol-toml) → Plan model
  - **F3** Reflect a source edit in the view  _Dir↓ ≤1s_
    - **How**: in-app split editor, re-parse on every keystroke (instant); autosave to localStorage. Chosen over Vite-HMR-on-file (needs a running toolchain) and load-file-only (slow loop). See T3.
      - **Component**: **C4 Split editor** (editor pane + Vue reactivity)
- **G3** Know whether external Milestones are at risk  _W:7_
  - **F6** Render a Milestone and flag its unmet required Features  _Dir→ correct Week; unmet identifiable_
    - **How**: `[[milestone]]` references Features by name; renderer draws a vertical line at the milestone Week and marks which required Features are undelivered
      - **Component**: C2 (membership + unmet computation), C3 (vertical line overlay)
- **G5** Hand stakeholders a shareable read-only view  _W:5_
  - **F7** Export the rendered plan as a shareable image  _Dir→ one click → PNG_
    - **How**: client-side DOM-to-PNG (html-to-image) → clipboard + download. Chosen over hosting a URL, which has no data unless the source is also shipped (local-first tool). See T1, T4.
      - **Component**: **C6 Image exporter**
- **F2** Classify each Delivery on-time/late vs the Original Estimate  _Dir→ 100% correct per ADR-0001_ (serves G1)
    - **How**: pure derivation in the Plan model — compare Delivery Week to the Original Estimate Week; never to a Re-estimate
      - **Component**: **C2 Plan model** — derives contiguous Monday Weeks, classifies markers, computes Milestone membership

### Components

| ID | Component | Realises | ADR |
|----|-----------|----------|-----|
| C1 | TOML source + parser (smol-toml) → Plan model | F4, feeds F2 | ADR-0002 |
| C2 | Plan model — Week derivation, on-time/late classification, Milestone membership | F2, F6 | ADR-0001 |
| C3 | Grid renderer (Vue + CSS Grid) — bars, symbols, colors, Now line, sticky panes, hover, trailing Learning column | F1, F5, F6 | — |
| C4 | Split editor — parse-on-keystroke, localStorage autosave | F3 | ADR-0002 |
| C5 | Plan library — named Macroplans in localStorage, switch/CRUD, Import/Export .toml | scope, persistence | ADR-0002 |
| C6 | Image exporter (html-to-image) — PNG to clipboard + download | F7 | — |

## 4. House — Goals × Functions

Cells: link strength (9 strong / 3 medium / 1 weak / blank none). Σ = `Σ(weight × strength)`.

|            | F1  | F2  | F3 | F4 | F5 | F6 | F7 |
|------------|:---:|:---:|:--:|:--:|:--:|:--:|:--:|
| G1 (10)    |  9  |  9  | 1  | 1  |    | 1  |    |
| G2 (8)     |  3  |     |    |    | 9  |    |    |
| G4 (8)     |  1  |     | 9  | 9  | 3  | 1  |    |
| G3 (7)     |  3  |  3  |    |    |    | 9  |    |
| G5 (5)     |  3  |     |    |    |    |    | 9  |
| **Σ**      | 158 | 111 | 82 | 82 | 96 | 81 | 45 |
| **Rel %**  | 24  | 17  | 13 | 13 | 15 | 12 | 7  |

**Top engineering priorities:** **F1 (render, 24%)** and **F2 (classify, 17%)** carry the most goal-value — together they *are* G1, the anchor goal, so the grid renderer and the Plan-model classifier deserve the most care. **F5 (15%)** ranks third despite a single goal because it is the *sole* driver of G2 (weight 8) — under-investing in frictionless Learning capture silently abandons the learning goal. The authoring pair **F3/F4 (13% each)** matter as a unit. **F7 (7%)** is genuinely a nice-to-have; keep it cheap. (Note: this importance lens differs from §7's risk lens, where F2 ranks first as the hard correctness gate.)

## 5. Roof — Function × Function tradeoffs

`◎` strong reinforce · `○` mild reinforce · `×` mild conflict · `⊗` strong conflict.

|        | F1 | F2 | F3 | F4 | F5 | F6 | F7 |
|--------|:--:|:--:|:--:|:--:|:--:|:--:|:--:|
| **F1** | —  | ○  | ×  |    |    |    | ×  |
| **F2** |    | —  |    | ○  |    |    |    |
| **F3** |    |    | —  | ◎  |    |    |    |
| **F4** |    |    |    | —  |    |    |    |
| **F5** |    |    |    |    | —  |    |    |
| **F6** |    |    |    |    |    | —  |    |
| **F7** |    |    |    |    |    |    | —  |

**Conflicts that actually shape the design:**
- **F1 × F7 (×).** The richer F1's *hover-only* content, the more an exported image (F7) loses. Mitigation: keep the status *color* always-visible; only the note is hover-only. Owned by tension in §8.
- **F1 × F3 (×).** A heavier render (sticky panes, many cells) can slow the ≤1s reflect loop. Mitigation in §7: debounce / parse only changed blocks.
- **F3 ◎ F4.** Instant reflect + local ripple-free edits reinforce strongly — together they *are* fast authoring (G4). Invest in them as a pair.
- **F2 ○ F4.** TOML's explicit date literals feed reliable classification — structured source *helps* correctness (this is why the earlier "terse-vs-robust" tension dissolved once we chose TOML over a DSL).

## 6. Function → Component map

Strength of each Component in realising each Function (9/3/1/blank). Component list and ADR anchors are in §3.

|        | C1 | C2 | C3 | C4 | C5 | C6 |
|--------|:--:|:--:|:--:|:--:|:--:|:--:|
| **F1** |    | 3  | 9  |    |    |    |
| **F2** | 3  | 9  |    |    |    |    |
| **F3** | 3  |    |    | 9  |    |    |
| **F4** | 9  |    |    | 3  |    |    |
| **F5** | 3  |    | 9  |    |    |    |
| **F6** |    | 9  | 3  |    |    |    |
| **F7** |    |    | 3  |    |    | 9  |

**C3 (Grid renderer)** and **C2 (Plan model)** each anchor three functions — they're the load-bearing components and the most important to get right and test hard.

## 7. Critical performance budget

| Rank | Function | Target | Watched on | If we miss it |
|------|----------|--------|------------|---------------|
| 1 | F2 | 100% correct on-time/late vs Original Estimate | unit tests over sample plans (incl. multi-slip, deliver-early, overdue) | classification is the product — block release; it's pure logic, so a failing test is a hard stop |
| 2 | F1 | reader IDs a state ≤3s; legible past the viewport | manual review on a 30-feature / 26-week sample; check sticky panes | drop hover-only data into always-visible cells; simplify symbol styling |
| 3 | F3 | ≤1s edit→view | eyeball on keystroke with a large plan | debounce parse; parse only changed blocks |
| 4 | F7 | one-click PNG, faithful to on-screen | manual export of a real plan; diff against screen | fall back to download-only if clipboard API is flaky; document "what you see is what exports" |

## 8. Tradeoffs — Got / Paid / ADR

| ID | Tradeoff | Got | Paid | ADR |
|----|----------|-----|------|-----|
| T1 | DOM/CSS Grid render over monospace text block | sticky panes, real colors, hover, image export | can't paste the plan as plain text; more layout code | — |
| T2 | TOML over a bespoke terse DSL (and over YAML) | robustness, native date literals, no parser to maintain, forgiving for a non-expert | verbose per Feature; source doesn't *look like* the plan | ADR-0002 |
| T3 | In-app split editor over Vite-HMR-on-file | instant loop, no toolchain for readers, works from static build | plan isn't a plain repo file by default (mitigated by Import/Export) | ADR-0002 |
| T4 | Image export over hosted URL | no data-hosting problem, paste into Slack/decks | snapshot loses hover content (status notes) | — |
| T5 | In-app plan library over single-document | switch plans without file juggling | list/CRUD UI, naming, localStorage to manage | ADR-0002 |

### Tensions being watched (unresolved by design)

- **Hover content vanishes in the exported image (F1↔F7).** For now we accept it: the colored status dot is always visible; only the *note* is lost. **Trigger to revisit:** if shared snapshots regularly need the notes, add an "expand notes inline before export" toggle.
- **localStorage is the only live store (durability).** Accepted because Import/Export .toml is the durable, git-trackable backup. **Trigger to revisit:** first time a plan is lost, or when multi-device editing is needed → consider file-system-access API or a sync backend.
- **No multiplayer / real-time collaboration (v1).** Deliberately single-user, local-first per ADR-0002. A future version may add a **backend + database with a CRDT layer syncing edits to the same TOML** (the format and the pure Plan-model derivation are chosen to not block this). **Trigger to revisit:** when two people need to edit one Macroplan at the same time → spike a CRDT (e.g. Yjs) over the TOML document, behind the existing in-app editor.

## 9. Inconsistencies spotted and fixed

- **F8 was a solution, not a function.** "Keep names pinned while scrolling" named sticky panes (a How) and an outcome already in G1. Folded legibility-at-scale into F1's target; sticky panes became a How under F1.
- **F5 over-specified coverage.** Originally "Learning on 100% of delivered rows"; corrected — a Learning is *optional*, the function is low-friction capture, not coverage.
- **F7 assumed hosting.** Originally "ship as a static hosted artifact"; a hosted URL has no data for a local-first file-based tool. Reframed to client-side image export, which actually serves G5 better.
- **F4 conflated terseness with ergonomics.** Originally "~1 feature = 1 line"; the real property for G4 is *local, ripple-free* CRUD. Reframed; terseness target dropped (TOML is not 1-line and that's fine).

## How to keep this honest

- When a new ADR lands → add its components to §3/§Components and re-score affected rows.
- When a spike / measurement returns numbers → update §7 `Target` / `Watched on`.
- WHATs (§1) change rarely; HOWs (§2) change per release; the cascade (§3) is recomputed when either side changes.
- If a section becomes empty after edits, delete it — empty sections lie.
