What regulators actually ask for, and what most data teams prepare instead
A forty-page policy answers a question nobody asks. Supervisory reviews test whether your controls are demonstrable, not whether they are written down.
Migrating off a legacy warehouse without freezing the business for six months
Parallel running with automated reconciliation is slower than a big-bang cutover, and it is the only approach that stays reversible at every step.
Why dashboard adoption stalls, and what to build instead
Usage peaks in week two and decays to nothing by month four. The fix is to ask what the viewer is meant to do differently after looking.
Testing data like software
A green pipeline run proves execution, not correctness. The failure modes that matter are the ones that complete successfully.
Data ownership is not a RACI chart
Naming an owner changes nothing unless the role comes with time, a veto that holds, and a notification path that does not rely on being remembered.
The strangler pattern does not port cleanly to data platforms
Applications have a routing layer to intercept. Data platforms do not, and finding the real seam is most of the work.
Metrics that survive contact with a board meeting
Board meetings apply pressures that internal review never does. The failure modes are predictable enough to design against.
dbt at scale, and what breaks after model three hundred
The practices that were fine at thirty models are actively harmful at three hundred. Most of the fixes are cheap if done early.
The data catalogue nobody opens
Catalogues fail because they answer a discovery question analysts do not have, in a place they do not go, with content they cannot trust.
What a warehouse migration actually costs, line by line
Budgets are wrong in a consistent direction. The engineering is estimated well. The categories that do not look like engineering are left out.
The decision log, and why almost nobody keeps one
Analytics teams document everything except the decisions the analysis was for. Five fields, written at the time, solve four recurring problems.
Before you buy an AI analyst, four preconditions
A conversational interface raises the cost of a poorly modelled warehouse, because it removes the human who was quietly compensating for it.
