Spec Driven Development

Turn approved specifications into governed implementation work.

Pipelix supports Spec Driven Development by connecting engineering specifications to bounded AI implementation, configured validation, independent review, and evidence—while keeping human approval in the workflow.

Specifications are optional in Pipelix. Teams can continue to execute normal backlog tasks and engineering work without adopting a specification-first process.

What Spec Driven Development adds

A specification can give Pipelix a more structured execution contract than a single backlog item alone—covering requirements, constraints, acceptance criteria, implementation boundaries, and expected behavior. This is useful when a team wants more formal planning and human approval before AI implementation begins.

How the workflow fits into Pipelix

For teams that adopt it, Spec Driven Development adds a planning and approval stage in front of the execution model Pipelix already uses.

A Spec Driven Pipelix workflow
  1. Requirement / Azure DevOps PBIThe originating need, request, or backlog item.
  2. SpecificationRequirements, constraints, acceptance criteria, implementation boundaries, and expected behavior are documented.
  3. Human ApprovalA person reviews and approves the specification before implementation begins.
  4. Implementation TasksThe approved scope is broken into bounded implementation tasks.
  5. Pipelix ExecutionPipelix carries each task through bounded AI implementation.
  6. ValidationConfigured project checks and validation commands run against the change.
  7. Independent ReviewAn independent review stage assesses the result against the specification.
  8. Evidence / HandoffStatus, logs, and review outcomes stay visible for engineering handoff.

Once tasks reach execution, Pipelix carries the work through the same execution, validation, review, and evidence stages used across the platform—the specification simply supplies more of the intent up front.

Existing workflows remain valid

Spec Driven Development is one supported workflow, not a prerequisite. Pipelix can also operate directly on bounded engineering work without a specification phase—Azure DevOps backlog items, bugs, maintenance tasks, technical debt, repetitive engineering work, routines, QA-related tasks, and targeted implementation tasks all remain supported today. Spec Driven Development adds a planning and approval layer on top of this execution model when a team wants it. See Azure DevOps backlog automation, technical-debt automation, and scheduled engineering routines for these existing workflows.

An orchestration layer, not a single workflow

Pipelix acts as an AI orchestration layer across engineering work. In a Spec Driven workflow, that same orchestration can carry an approved specification through implementation, validation, review, and handoff; outside that workflow, it carries an approved backlog item or routine through the same stages.

Azure DevOps and specifications

For teams using Spec Driven Development, the relationship is conceptual: a requirement or Azure DevOps PBI leads to a specification, a person approves it, and the approved scope is broken into implementation tasks. Those implementation tasks can then be created in Azure DevOps and processed through the normal Pipelix task flow. Not every Azure DevOps task originates from a specification—most bounded work items can go directly to Pipelix without one, as described in Azure DevOps backlog automation.

Human control stays in the workflow

Spec approval is an additional human-control boundary available to teams that want it, alongside Pipelix’s existing controls: humans determine intent, work remains bounded, project-specific validation can run, implementation can be independently reviewed, evidence remains visible, and engineers retain merge and deployment responsibility. See governed AI software development and AI engineering operations for the broader operating model.
