Documentation Development Lifecycle (DDLC)
The Documentation Development Lifecycle defines how documentation moves from planning to publishing and maintenance.
Context: Product and engineering environments where documentation needs to scale with releases.
Focus: A lifecycle model for planning, writing, reviewing, publishing, and maintaining documentation.
Purpose
DDLC creates a structured process for documentation work so teams do not rely on ad hoc execution.
Lifecycle Stages
The lifecycle typically includes:
- planning
- content design
- drafting
- review
- publishing
- maintenance
When it is used
This model is useful when:
- integrating documentation into release workflows
- improving content quality and predictability
- establishing ownership and review gates
- reducing post-release documentation gaps
Outcome
DDLC helps documentation become a repeatable operational process instead of a last-minute deliverable.
