A feature specification answers one question: can an engineer build this without asking the PM anything? 68% of engineering re-requests trace back to spec ambiguity (Scriptonia, 2026). This template eliminates that 68% — every section exists to remove a specific class of ambiguity.
"The best feature specs read like a conversation between the PM and every engineer who will ever work on it. Anticipate the questions. Answer them in the doc. The fewer the questions at standup, the better the spec."
— Leo C., Staff Engineer at a SaaS platform company
Feature spec template (full)
Header
Feature name | Owner | Status (Draft / In Review / Locked) | Last updated | Sprint target
TL;DR (2–3 sentences)
What this feature does, for whom, and why it matters. Engineers read this first — make it scannable.
Problem statement
The specific user problem this solves. Include behavioral evidence (support tickets, user interviews, usage data). No aspirational language.
User stories
As a [specific persona], I want [specific action] so that [measurable outcome].
3–8 stories. Each story gets its own acceptance criteria below.
Acceptance criteria (per story)
Given/When/Then format. 3–5 criteria per story. Explicitly include negative paths (what happens on failure, empty state, permission denied).
Edge cases
At least 5. For each: scenario + expected system behavior. This is the section that prevents 2am production incidents.
Out of scope
Explicit list of what this feature does NOT include. As important as the in-scope list.
Technical notes
PM-visible technical constraints: rate limits, existing API contracts, performance targets. Not architecture prescriptions — those go in the tech lead's separate architecture doc.
Dependencies
External system | Owner | Status | Blocking or non-blocking
Open questions
Question | Owner | Deadline
Unresolved questions must be resolved before sprint planning, not during development.
Success metrics
Metric | Baseline | 30-day target | 90-day target
At least one metric measurable within 2 weeks of launch.
How to use this template with AI
Scriptonia generates all sections of this template from a plain-language feature description. Input: 2–4 sentences covering the user, the problem, and the core behavior. Output: a complete spec draft ready for PM review and engineering sign-off.
