SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Milestones are critical control points in project work, but without a consistent lifecycle process they can become ambiguous, misaligned, and hard to audit.

Core Features & Use Cases

Lifecycle orchestration: create, track phases, complete, archive, and prep the next milestone with minimal manual overhead.
State and knowledge preservation: centralize milestone state and generate summaries for audits and retrospectives.
Guardrails and transitions: enforce required fields (goals, scope, success criteria) and ensure clean state transitions between milestones and versions.

Quick Start

Create a new milestone with milestone-lifecycle create "MS-01" and define its goals, version, and success criteria.

FAQPage Schema

How do I manage project milestones from creation through archiving without manual overhead?▼

Milestone lifecycle orchestration manages project milestones from creation through archiving by enforcing milestone manifests, tracking phase states, and applying validation checks to ensure clean transitions and minimal manual overhead.

What is the best way to enforce required fields like goals and success criteria for project milestones?▼

To enforce required fields for project milestones, apply lifecycle guardrails that mandate goals, version, scope, and success criteria before transitioning states, ensuring alignment and preventing ambiguous milestone definitions.

How do I preserve milestone state and generate summaries for project audits?▼

Preserve milestone state and generate audit summaries by centralizing milestone manifests and archiving artifacts during the completion phase, capturing knowledge for retrospective analysis and continuous auditability.

Can I track milestone phases within a colony project using a structured lifecycle process?▼

Yes, you can track milestone phases within a colony project by applying a structured lifecycle process that enforces state transitions, validation checks, and knowledge preservation throughout the project management workflow.

Do I need to define a milestone manifest before starting new project phases?▼

Yes, defining a milestone manifest is required before starting new project phases, as it enforces the necessary goals, version, and success criteria to ensure clean state transitions and proper governance.

When should I archive milestone artifacts during the project lifecycle?▼

Archive milestone artifacts during the completion phase of the project lifecycle, after validation checks pass, to preserve state, generate summaries for audits, and prepare seamlessly for the next milestone.
