The architecture as components
Describe what "Give each concern exactly one owner" changes in practice.
Step 1 of 3
The architecture as components
Give each concern exactly one owner. Capture resolves identity; orchestration sequences the work; enrichment runs the provider waterfall and cache; the warehouse holds usage and scores; the CRM holds account owners, routes and rep activity; observability joins events with one trace; action sends personalized outreach idempotently. Keep one writer per field so the layers do not fight.

The Stack, One Writer per Concern
Interactive diagram. Tab through its regions; each focused region shows its detail in the panel below.
Each layer rests on the one below; the warehouse and CRM own different fields and never fight over them.
Two inflection points turn an internal tool from a localhost script into a cross-functional asset. The first is hosting: a usage dashboard or a Salesforce-embedded usage calculator stays a personal hack until an AE counterpart asks "can you send me a link?" - the fix is putting it on something like Vercel so anyone reaches it from a web page, with version control over how it's accessed. The second is live data: trade imported CSV snapshots for a proxy access layer or webhooks into the warehouse, so the tool shows account-360 visibility in real time. These connectivity and hosting needs sit outside Cursor-the-IDE - they're the systems-design step, and they're often the bridge from a no-code Airtable prototype to real code.
"the biggest inflection point was hosting these solutions on something like a versel... and then the kind of data connectivity as well. Make sure that's done by web hooks or proxy query connections to backend live data."
