Mapping a four-brand tech stack to find the silos

A staffing group with four brands, two CRMs, and a dozen tools had no single picture of how data moved. One diagram made the gaps visible and set the integration priorities.

Anonymized. Brand names and niche vendors generalized; the architecture is as mapped.

When a company grows by adding brands, the tech stack grows by accretion. Each brand picks what it needs; nobody draws the whole thing. The symptom is a question that should be simple and is not: "if a candidate fills out the form on brand A's site, where does that record end up?" This group could not answer it without three people on a call.

The map

The diagram below is the deliverable. Brands on the left, tools grouped by who uses them, and every connection drawn with a line style that says what kind of relationship it is.

Solid colored lines are ownership or active integrations. Dashed borders mark tools shared across brands. Amber marks an integration being enabled. Red dashed lines mark the gaps: tools that do not talk to each other.

What the map made obvious

What came out of it

  1. A gaps-and-actions list, ranked. Each red line became a row with the current state, the desired state, a priority, and an owner column. The ATS-to-payroll silo was marked the highest architectural risk in the stack.
  2. A tool inventory that lives beside the map. Every tool with its category, the brands it serves, integration status and partners, its purpose, and where the admin and documentation live. The map and the inventory now change together.
  3. The automation bridge recorded as an integration in its own right. A Zapier flow that carries every website inquiry is infrastructure, not a convenience, and it is now listed and versioned like one.

How to build your own

  1. List every tool with its owner and which business units use it. Expect to find two or three nobody remembers buying.
  2. Draw brands or business units on one side and tools grouped by who shares them.
  3. Draw every connection, and be honest about the ones that do not exist. The red dashed lines are the point of the exercise.
  4. Keep it as a living document. Version it; date it; re-check it whenever a contract renews.
A note on tools

The diagram is built in plain-text Mermaid, so it lives in version control and re-renders when the stack changes. A whiteboard tool works too. What matters is that one picture exists and someone owns it.
