One‑Page Launch Dossier: Turn a One‑Page PRD into Store‑Ready Assets in 90 Minutes

A one‑page launch dossier is a tightly structured artifact that moves a one‑page PRD from idea into the marketing and QA assets contractors need to deliver launch‑ready creatives. It focuses on outcomes: headline value, core user flows, three prioritized features, measurable acceptance criteria, and creative hooks for screenshots and copy.

This form works because it reduces back-and‑forth. Instead of leaving designers, copywriters, and QA to infer product intent from a long PRD or scattered messages, the dossier provides the exact inputs they need: imagery targets, short benefit headlines, testable acceptance criteria, and a small JSON‑LD block for SEO and discovery.

Set a 90‑minute timer and work in three 30‑minute sprints: (1) Clarify (product owner + PM): refine the one‑line value proposition, target persona, and three prioritized features with one acceptance criterion each. (2) Creative (designer + copywriter): map each feature to an ASO screenshot idea, a 10–12 word headline, and choose hero screen images. (3) Handoff & QA (engineer + QA): produce a JSON‑LD SoftwareApplication snippet, a 3‑test acceptance checklist, and package instructions for contractors.

For clarity, use fixed deliverables per sprint: a filled dossier template page, five screenshot captions (prioritize first three), one JSON‑LD block, and three acceptance tests written as Given/When/Then. These artifacts let a designer produce final screenshots, a marketer draft store copy, and QA run deterministic checks without another meeting.

Constrain each screenshot to a single message: problem → benefit → proof. For most stores you’ll prioritize the first three frames. Capture: (A) headline (8–12 words), (B) supporting subline (optional), and (C) the exact in‑app screen or mockup to use. Keep typography legible at small sizes and use a consistent background to unify the set.

Include technical screenshot specs for contractors. Use the App Store Connect screenshot requirements for Apple and the Play Store’s recommended dimensions for Android as non‑negotiable constraints. In the dossier, paste target pixel sizes, orientation, and the primary export format (PNG) so designers can export correctly on first pass.

A compact JSON‑LD SoftwareApplication block provides structured data for search engines and can be dropped into the app landing page or press kit to improve discovery and rich results. Keep the block minimal: name, description (one short sentence), operatingSystem, applicationCategory, and featureList or screenshot references if relevant.

Follow schema.org and Google’s Search Central examples for SoftwareApplication so your markup validates and remains future‑proof. Include the JSON‑LD as a text file in the dossier and a single instruction: “Paste into page head or include via server‑side template.” This keeps the task trivial for engineers during handoff.

Write three acceptance tests (happy path) as Given/When/Then statements that map to the prioritized features. Keep them short and specific so QA or contractors can convert them into automated tests or manual checklists quickly. Attach expected screenshots or sample data for each test so outputs are unambiguous.

Finish the dossier with launch copy: a 30‑word app description, three 10–12 word screenshot headlines, and a 1‑line press blurb. Add handoff notes listing file names, component owners, deadlines, and where to upload final assets (e.g., the project’s shared folder). This small ritual removes most last‑minute questions and accelerates review cycles.
