Custom engagement path
How assessments run
Step-by-step process for Web Willow Hub ETL reliability assessments — from scoping call to findings walkthrough.
The ETL Reliability Assessment is our flagship consultation. This page shows how the engagement actually unfolds so you can prepare stakeholders and access before kickoff.
What an assessment is (and is not)
It is a time-boxed investigation into how your extract–transform–load paths behave under real schedules, retries, and late upstream data. It is not a product demo, a maturity score marketing exercise, or an invitation to replace your stack wholesale.
The path
Scoping call
Thirty minutes to name critical pipelines, current pain (late loads, silent drops, flaky retries), and whether an assessment or another consultation fits better.
Access & counterparts
You designate a technical counterpart. We agree on read access to job definitions, recent run history, and incident notes. No production write access is required for the assessment itself.
Discovery
We inventory jobs, dependencies, and SLAs. Early findings often appear here: undocumented handoffs, clocks that disagree, or alerts that only fire on process crash.
Deep-dive workshops
Paired sessions with your engineers to reproduce failure modes, walk lineage for priority feeds, and pressure-test retry and idempotency assumptions.
Findings & walkthrough
You receive a written reliability plan and a live review. Items are ranked by blast radius and effort so the next sprint can absorb them.
Typical timeline
Most assessments complete in two to three weeks of calendar time, depending on access speed and how many pipelines sit in scope. Rush engagements are possible when a single critical chain is failing repeatedly; we will say honestly if rushing would hollow out the review.
After the assessment
Some teams continue with a reliability retainer for implementation support. Others take the backlog in-house. Either path is fine — the assessment stands on its own.
