Quiz

Your team's on-call phone has not been paged in nine days and every dashboard is green. Why is that not yet evidence that anything is healthy, and what single mechanism turns silence into a signal?

An analytical platform's cost has grown faster than its usage. Which controls actually reduce it?

An analytics platform's cost is growing faster than its usage. What causes it, and which controls work without blocking analysts?

An analytics platform's query costs are growing faster than its data. What are the drivers and controls?

One analyst's query cost £4,000 in a single afternoon. Leadership wants a policy. What do you actually implement?

The analytics bill has tripled in six months with no corresponding growth in users or data volume. Where do you look?

A card platform integrates with a network whose data model and semantics differ fundamentally from its own. Where should the translation live and what discipline does it require?

A new service must integrate with a legacy system whose data model is entangled and poorly named. What does an anti-corruption layer actually do, and how do you know it is working?

A platform integrates retailer systems with inconsistent models. What does an anti-corruption layer prevent, and where does it belong?

A team integrates a vendor CRM whose customer model contradicts theirs. Six months later vendor field names and status codes appear throughout the codebase. What was missing and what is the fix now?

A team generates its entire API reference from code annotations and deletes the hand-written guide. Six months later integrators are opening more support tickets, not fewer, and every one of them is technically answerable from the reference. What did generation buy, and what did it destroy?

A workspace platform's API is well designed but developers repeatedly build integrations that break under real conditions. What is missing from the documentation, and what should be added?
