Delivery Planning — Risk & Sequencing Rationale
The why behind the Bolt order. Bolt is one build pass over a piece of the work, ending in something that runs. The economic order chosen here is: value core first, then the higher-unknown parallel pair, then integration.
Sequencing argument
The chosen order balances early working software (Q1=A) with de-risking the uncertain parts early (Q6=B,C,D — the user's worries: funnies unpredictability, AI drafting quality, review-handoff reliability).
- Bolt 1 —
generatorcore first (value/skeleton case). Builds the central, highest-confidence capability: CLI → content → layout → emit → A4 print. The paper works end-to-end with hand-written content early, so the highest-value surface (the printable broadsheet) is proven before the exotic parts land. This also naturally satisfies the affirmed "no separate walking skeleton": the first Bolt IS a thin end-to-end slice (markdown in → A4 page out) without calling it one. - Bolts 2a/2b —
ai-draftandfunniesin parallel (risk-reduction). The two most unpredictable units — AI copy quality and content-derived puzzle/ cartoon generation — are independent, so they build concurrently (Q4=B). Both de-risk the user's stated worries (Q6=B,C) before integration. Each is also independently testable (DraftBundle contract; puzzle+cartoon output). - Bolt 3 — integration last. Wires the two new units into the core and completes the full-chain fidelity (multi-page print, photo embed, per-article review handoff). The review-handoff reliability worry (Q6=D) is addressed here against the file:// no-server constraint.
Reference heuristic
No formal WSJF score (Q2=A). The order follows a pragmatic mix: value-first + risk-reduction + dependency-aware. It is coherent with Reinertsen's CD3-style reasoning (deliver value early while sequencing the high uncertainty soon enough to learn from it), but we did not compute a numeric score.
Deviation-from-topology note
The Bolt order does not strictly follow 2.7's topological order. Topology
says generator depends on ai-draft and funnies; a strict topological walk
would build ai-draft + funnies first. We deviate deliberately: Bolt 1 builds
generator with simple/sample content first (no ai-draft/funnies needed for
the core hand-written path), then the independent pair in parallel (Bolt 2a/2b),
then integration (Bolt 3). This is justified by Q1=A (value core early) and the
parallelism in Q4=B. The deviation is captured here as the stage requires.
Rationale
| Bolt | Rationale |
|---|---|
| Bolt 1 | Value core, highest confidence, end-to-end early |
| Bolt 2a | Independent + user worry (AI quality/drafting) — de-risk |
| Bolt 2b | Independent + user worry (funnies) — de-risk |
| Bolt 3 | Integration + full fidelity (incl. print-fidelity worry Q6=A) |
