Roadmap CARD vs. JIRA states: mapping
Roadmap CARD JIRA equivalent Meaning
Concept Drafting Strategic direction and topic identified to have further planning, before
resourcing and prioritization decision can be made. Preliminary
JIRA/blueprints and artifacts may exist but they are being drafted.
Forecast date is for rough target want to aim for.
Approved Drafting The TSC has reviewed the concept and has prioritized the EPIC with
timescale and resource limits. Roadmap cards that need to be
associated with the Approved Concept EPIC can proceed at the
engineering/OPSCOM review level.
Planning Planning Planning has been done for a task, JIRA card/Blueprints exist and
resource estimates and gating dependencies are known. Owner team
has been identified and TSC agreed prioritization has been secured.
Some preliminary development maybe in progress. Forecast date
may change based on when dependencies are met.
Development Engineering Engineering teams are actively working on the task. Expectation is that
resources are available and dependencies have been met and forecast
date reflects high confidence.
Released Delivered Work item has been made available to target audience (Members or
Public) and all associated artifacts are updated to reflect status. (JIRA
cards, Blueprints, etc. have the correct status).
