DIVIO Documentation Framework

The Four Quadrants

Exactly four documentation types. Each serves one purpose. Never mix.

Tutorial

Orientation: Learning | Need: "Teach me" | Key Q: Can newcomer follow without external context? Purpose: enable first success | Assumption: user knows nothing | Format: step-by-step guided experience Success: gains competence + confidence | Include: safe repeatable steps, immediate feedback, building blocks Exclude: problem-solving, assumed knowledge, comprehensive coverage

How-to Guide

Orientation: Task | Need: "Help me do X" | Key Q: Achieves specific, measurable outcome? Purpose: accomplish specific objective | Assumption: baseline knowledge, needs goal completion Format: focused steps to outcome | Success: task completed Include: clear goal, actionable steps, completion indicator | Exclude: teaching, background, all scenarios

Reference

Orientation: Information | Need: "What is X?" | Key Q: Factually complete and lookup-ready? Purpose: accurate lookup | Assumption: user knows what to look for | Format: structured, concise, factual Success: finds correct info quickly | Include: complete API/function details, parameters, returns, errors Exclude: narrative, tutorials, opinions

Explanation

Orientation: Understanding | Need: "Why is X?" | Key Q: Explains reasoning and context? Purpose: conceptual understanding | Assumption: user wants "why" | Format: discursive, reasoning-focused Success: understands design rationale | Include: context, reasoning, alternatives, architectural decisions Exclude: step-by-step, API details, task completion

Classification Matrix

                  PRACTICAL           THEORETICAL
STUDYING:         Tutorial            Explanation
WORKING:          How-to Guide        Reference

Adjacent: Tutorial/How-to (both have steps, differ in assumed knowledge) | How-to/Reference (both "at work") | Reference/Explanation (both knowledge depth) | Explanation/Tutorial (both "studying")

Classification Decision Tree

START: What is the user's primary need?

1. Is user learning for the first time?
   YES -> TUTORIAL
   NO  -> Continue

2. Is user trying to accomplish a specific task?
   YES -> Does it assume baseline knowledge?
         YES -> HOW-TO GUIDE
         NO  -> TUTORIAL (reclassify)
   NO  -> Continue

3. Is user looking up specific information?
   YES -> Is it factual/lookup content?
         YES -> REFERENCE
         NO  -> Likely EXPLANATION
   NO  -> Continue

4. Is user trying to understand "why"?
   YES -> EXPLANATION
   NO  -> Re-evaluate (content may need restructuring)

Classification Signals

Tutorial Signals

Positive: "Getting started", "Your first...", "Prerequisites: None", "What you'll learn", "Step 1, Step 2...", "You should see..." Red flags: "Assumes prior knowledge", "If you need to...", "For advanced users..."

How-to Signals

Positive: "How to [verb]", "Before you start" (with prerequisites), "Steps", "Done:" or "Result:" Red flags: "Let's understand what X is...", "First, let's learn about..."

Reference Signals

Positive: "API", "Parameters", "Returns", "Throws", "Type:", Tables of functions/methods Red flags: "This is probably...", "You might want to...", Conversational tone

Explanation Signals

Positive: "Why", "Background", "Architecture", "Design decision", "Trade-offs", "Consider", "Because" Red flags: "1. Create...", "2. Run...", "Step-by-step", "Do this:"

JTBD-First Resolution (When in doubt, ask the JTBD)

Provenance: Ale 2026-05-02. "La JTBD ci dice quale need stiamo soddisfando."

When the four-types decision tree is ambiguous, OR when a stylistic decision inside a chosen type has plausible alternatives (ordering, fold-vs-keep, scratch-vs-real-data, prose-vs-table, etc.), DO NOT pick by aesthetic preference. Return to the document's JTBD and let the answer fall out.

Each Diataxis type maps to a canonical JTBD:

Application: resolving a stylistic dispute

Worked example, Tutorial Q: scratch directory vs use the project's seeded data?

• JTBD: "Build mental model end-to-end without risking my real project state."
• Constraint surfaced: "without risking" → seeded data DOES risk contamination → scratch wins.
• Constraint surfaced: "end-to-end" → cause-effect visible → seeded data hides cause-effect under pre-existing entries → scratch wins.

Worked example, Reference Q: fold three short sections into one "Notes"?

• JTBD: "Look up a specific answer."
• Constraint surfaced: "specific answer" → ctrl-F friendly → 3 distinct H2 entries are 3 distinct landing points → folding hurts the JTBD.
• Verdict: keep separate.

Worked example, README "Learn More" Q: alphabetical or semantic grouping?

• JTBD on a README is "I'm new; show me docs in the order I should read them" — pedagogical browsing, NOT lookup.
• Constraint surfaced: "in the order I should read them" → semantic grouping (install adjacent, authoring adjacent, troubleshooting last) → wins.
• Alphabetical serves a DIFFERENT JTBD ("I know the doc name") which has another surface (file system / search).

Decision protocol

When facing a stylistic ambiguity inside a chosen type:

1. Restate the document's JTBD in one sentence (use the canonical JTBD as the starting point, refine if the doc is more specific).
2. List the constraints implied by that JTBD (be concrete: "reproducible", "ctrl-F friendly", "links to evidence").
3. Compare each candidate option against the constraint list.
4. Pick the option satisfying the most constraints. If tied, pick the option that fails the FEWEST constraints (loss-aversion).

This procedure replaces aesthetic debate with a falsifiable check.

Anti-pattern: collapse via JTBD-blending

Some authors blend two JTBDs in one document ("a Tutorial that's also a Reference"). This is the same collapse pattern the four-types-only rule rejects, surfaced via the JTBD lens. Detection: if the document has TWO canonical JTBDs in tension (e.g. "build mental model" AND "look up specific answer"), flag for splitting.
