Consultation
ETL Reliability Assessment
A structured review of extract–transform–load paths that surfaces failure modes, lineage gaps, and a prioritized reliability backlog your team can execute.
Typical duration: Typically 2–3 weeks from kickoff to written findings
Delivery: Remote sessions with optional on-site days in Kaohsiung or Taipei
Pricing basis: Fixed engagement fee, scoped after a free 30-minute call
Who it is for
Operations and analytics engineering teams that own overnight or near-real-time ETL and keep losing confidence after silent failures, late landings, or unexplained row-count drift.
Result you walk away with
A written reliability plan: ranked findings, evidence from your own runs, and concrete remediation steps sized for one or two sprints — not a multi-year rewrite proposal.
Scope included
- Kickoff interview with pipeline owners and on-call
- Review of job definitions, schedules, dependency graphs, and recent incident notes
- Sampling of failure logs and reconciliation checks for agreed critical feeds
- Working session on retry, idempotency, and alerting gaps
- Final findings document and a live walkthrough
Out of scope
- Building a new warehouse platform from scratch
- Vendor license negotiation
- 24/7 managed operations coverage
Provider
Senior consultants at Web Willow Hub with hands-on ETL and pipeline engineering backgrounds. You always know who is on the engagement.
Process
- Scoping call — confirm pipelines, SLAs, and access.
- Discovery week — document review and paired reading of job code.
- Deep-dive workshops — failure-mode mapping with your engineers.
- Delivery — findings, backlog, and optional follow-up office hours.
Preparation
Share read-only access to orchestration definitions, recent run history, and any existing data-quality checks. Name a single technical counterpart who can answer ownership questions within one business day.
