Baseline

Baseline

Intro

The Baseline is the current, approved state of architecture or process against which changes are measured. In EA, it anchors impact analysis and planning.

Key points:

  • Provides a reference point before changes
  • Enables comparison with target and transitional states
  • Common use cases: roadmap planning, risk assessment, compliance checks, cost benchmarking, capability maturity
  • Pitfall: stale baselines undermine trust and decisions

Examples:

  • Baseline application inventory by lifecycle status
  • Baseline technology standards and versions
  • Baseline capability maturity and ownership

In practice:

Establish baselines before starting initiatives within Enterprise Architecture.
