Brownfield Platform Assessment

A brownfield platform assessment helps teams understand existing risk, operational drag, and modernization options without assuming a full rebuild is required.

Assessment focus

Prioritize facts about:

• Critical services and owners.
• Runtime platforms and environments.
• Release process and rollback paths.
• Infrastructure ownership and drift.
• Secrets, identity, and privileged access.
• Observability, incidents, and recovery.
• Data stores, backups, and retention.
• Cost drivers and resource ownership.

Assessment flow

Outputs

A useful brownfield assessment produces:

• Current-state architecture map.
• Service and ownership inventory.
• Maturity scores with evidence.
• Top risks and constraints.
• Quick wins for urgent risk reduction.
• 30, 60, and 90 day roadmap.
• Decisions needed from leadership.

Recommended first moves

• Add missing ownership and escalation paths.
• Fix unsafe production access and secrets.
• Add dashboards and alert routes for critical systems.
• Document rollback and restore paths.
• Stop unmanaged drift in high-risk infrastructure.

Watchouts

• Do not start with a rewrite unless the evidence demands it.
• Do not trust diagrams without checking live systems.
• Do not let tool preferences replace risk prioritization.
• Expect undocumented dependencies and manual steps.
