Spec-driven development
for product teams building with AI

Quality isn't slower. Ambiguity is.

Stop prompting. Start specifying.
Executable is the spec-driven workflow that turns fuzzy product ideas into structured, testable specs - without losing context along the way.

Truth

Three questions every product team should be able to answer.

Executable is built around answering all three — at any point, for any part of your product.

What is the truth?

Teams shouldn't have to choose between stale documentation and reading the code. Executable is the central source of truth that describes your entire product and captures every design decision along the way.

Single source

How much of the truth exists?

See exactly how much of your product vision has actually been built and what's still outstanding — clear, trackable delivery across every feature and product area.

Defined vs. delivered

How much is working as expected?

Of everything that's been delivered, know how much is genuinely behaving as specified — full coverage tracked through executable, automated tests tied directly to the spec.

Verifiable coverage

The methodology

Three frameworks. One source of truth.

Executable combines three battle-tested product frameworks — story mapping, jobs-to-be-done, and behaviour-driven development — into a single, structured spec-driven development workflow. Product intent becomes executable specifications your team and AI coding agents can build against.

01

Structured

Story Mapping / Taxonomy

A place for every requirement — clear separation of concerns across your product domain.

02

Contextual

Jobs To Be Done

Situational contexts with clear outcomes and motivations — the glue that connects problem to solution domain.

03

Verifiable

Behaviour Driven Development

Concrete, testable examples of desired behaviour — unambiguous and executable.

Structured × Contextual × Verifiable

The flow

Executable fills the gap.

Teams don't fail at building. They fail at defining clearly enough for what to build — vision lives in prose that product, design, engineering and QA each read differently.

Executable drops into your existing loop: definition up front, verifiable tests on the back end — so prompting and code generation deliver on intent.

How it works

Built for definition. Wired for delivery.

Key capabilities that take your vision from fuzzy intent to shipped behaviour — without losing context along the way.

Definition

Structured Taxonomy

A place for every requirement.

An opinionated hierarchy for product areas, services, job stories and scenarios — clear separation of concerns and single responsibility, end-to-end.

AI Skills

Streamline definition. Surface gaps.

Purpose-built AI skills review business rules, draft scenarios, and run gap analysis across your specifications — so ambiguity gets caught before code does.

Parity

GitHub Integration

Specs in lockstep with code.

Two-way sync of .feature files into your repo — ready for CI test runners, PR review, and a single source of truth between product and engineering.

Extensibility

MCP Integration

Wire your agents into rich context.

Expose your specifications over MCP so external agents — IDE, Tests, Docs — work from the same structured intent, not from prompts and guesses.

Visibility

Workflow Overview

Bird's-eye view of the whole product.

A single spatial view across product behaviours and releases — see what's defined, what's ambiguous, and where coverage thins out. Perfect for collaborative team sessions.

Release Planning

Plan with full spec context.

Track coverage and delivery against scoped releases — every story, scenario and step rolled up so you know exactly what ships and what's still ambiguous.
